[0004] Electronic messaging, particularly instant messaging, continues to be popular worldwide. Users can quickly share electronic media content items including text, electronic images, audio, and video with each other instantaneously.

[0005] As the number of users on social networking systems increases, each user also has a growing network of individuals she follows. To maintain a user's engagement on a social networking system, it is most important for the system to have the ability to present to each user the media content items that she is most interested in or most relevant to. In addition to the need to curate media content items, social networking systems also face the challenge of providing a graphical user interface that attracts a user's attention and allows her to view the curated media content items and further interact with the network of individuals she follows.

[0027] In a messaging system, a user is connected to a variety of other users with whom they have different levels and types of relationships. For example, a user can be connected to his group of close friends as well as his colleagues, acquaintances, and people he does not know outside of the messaging system.

[0028] Embodiments of the present disclosure improve the functionality of electronic messaging software and systems by recognizing that a user may want to share media content items with a group of users (e.g., close friends) rather than with the remainder of the users to whom he is connected on the messaging system. Specifically, embodiments of the present disclosure generate an invitation media overlay for inviting one or more selected users (e.g., recipients) to join a private group that can access a private collection of media content items (e.g., images, pictures, text, videos, audio, etc.) generated by a user (e.g., a sender). When a recipient receives a media content item with an invitation media overlay from the sender, the recipient is more likely to continue engaging with the messaging system and send a response to the sender when the media content item received appears to be a direct personal message and allows him to join the private group.

[0029] Networked Computing Environment

[0030] Figure 1 is a block diagram showing an example messaging system 100 for exchanging data (e.g., messages and associated content) over a network. The messaging system 100 includes multiple instances of client devices 102, each of which hosts several applications including a messaging client 104. Each messaging client 104 is communicatively coupled via a network 106 (e.g., the Internet) to other instances of the messaging client 104 and a messaging server system 108.

[0031] The messaging client 104 is capable of communicating with and exchanging data with another messaging client 104 and a messaging server system 108 via a network 106. The data exchanged between the messaging clients 104 and between the messaging client 104 and the messaging server system 108 includes functionality (e.g., commands to trigger functionality) and payload data (e.g., text, audio, video, or other multimedia data).

[0032] The messaging server system 108 provides server-side functionality to a particular messaging client 104 via the network 106. Although certain functions of the messaging system 100 are described herein as being performed by the messaging client 104 or by the messaging server system 108, the location of certain functions within the messaging client 104 or the messaging server system 108 can be a design choice. For example, it may be technically preferable to initially deploy certain technologies and functionality within the messaging server system 108, but later migrate the technology and functionality to the messaging client 104 when the client device 102 has sufficient processing power.

[0033] The messaging server system 108 supports various services and operations provided to the messaging client 104. Such operations include sending data to the messaging client 104, receiving data from the messaging client 104, and processing data generated by the messaging client 104. The data can include, by way of example, message content, client device information, geolocation information, media enhancements and overlays, message content persistence conditions, social network information, and live event information. Data exchange within the messaging system 100 is triggered and controlled via functionality available through the user interface (UI) of the messaging client 104.

[0034] Turning now specifically to the messaging server system 108, an application programming interface (API) server 110 is coupled to an application server 112 and provides a programming interface to the application server 112. The application server 112 is communicatively coupled to a database server 118, which facilitates access to a database 120 that stores data associated with messages processed by the application server 112. Similarly, a web server 124 is coupled to the application server 112 and provides a web-based interface to the application server 112. To this end, the web server 124 processes incoming network requests via the Hypertext Transfer Protocol (HTTP) and several other related protocols.

[0035] The Application Programming Interface (API) server 110 receives and sends message data (e.g., commands and message payloads) between the client device 102 and the application server 112. In particular, the Application Programming Interface (API) server 110 provides a set of interfaces (e.g., routines and protocols) that the messaging client 104 can call or query to invoke the functions of the application server 112. The Application Programming Interface (API) server 110 exposes various functions supported by the application server 112, including: account registration; login functionality; sending a message from a particular messaging client 104 to another messaging client 104 via the application server 112; sending a media file (e.g., an image or video) from the messaging client 104 to the messaging server 114; and setting a collection of media data (e.g., a story) for access by another messaging client 104, retrieving a friend list of the user of the client device 102, retrieving such a collection, retrieving messages and content, adding and deleting entities (e.g., friends) to and from an entity graph (e.g., a social graph), locating friends in the social graph, and opening application events (e.g., related to the messaging client 104).

[0036] The application server 112 hosts several server applications and subsystems, including, for example, the messaging server 114, the image processing server 116, and the social network server 122. The messaging server 114 implements several message processing techniques and functions that particularly relate to the aggregation and other processing of content (e.g., text and multimedia content) included in messages received from multiple instances of the messaging client 104. As will be described in further detail, text and media content from multiple sources can be aggregated into content collections (e.g., called stories or galleries). These collections are then made available to the messaging client 104. Given the hardware requirements for other processor- and memory-intensive processing of the data, such processing can also be performed on the server side by the messaging server 114.

[0037] The application server 112 also includes an image processing server 116 that is dedicated to performing various image processing operations generally with respect to images or videos within the payload of messages sent from or received at the messaging server 114.

[0038] The social network server 122 supports and makes available various social networking functions and services to the messaging server 114. To this end, the social network server 122 maintains and accesses an entity graph 306 within the database 120 (as Figure 3as shown). Examples of functions and services supported by the social network server 122 include identifying other users in the messaging system 100 who have a relationship with or are “following” a particular user, and identifying the interests of a particular user and other entities.

[0039] System Architecture

[0040] Figure 2 is a block diagram showing further details of the messaging system 100 according to some examples. Specifically, the messaging system 100 is shown to include a messaging client 104 and an application server 112. The messaging system 100 includes a number of subsystems that are supported on the client side by the messaging client 104 and on the server side by the application server 112. These subsystems include, for example, a transient timer system 202, a collection management system 204, an enhancement system 206, a map system 208, and a game system 210.

[0041] The transient timer system 202 is responsible for implementing temporary or time-limited access to content by the messaging client 104 and the messaging server 114. The transient timer system 202 includes a number of timers that selectively enable access (e.g., for presentation and display) to messages and associated content via the messaging client 104 based on the duration and display parameters associated with a message or a collection of messages (e.g., a story). Additional details regarding the operation of the transient timer system 202 are provided below.

[0042] The collection management system 204 is responsible for managing groups and collections of media (e.g., collections of text, image, video, and audio data). Collections of content (e.g., messages including images, videos, text, and audio) can be organized into “event galleries” or “event stories”. Such collections can be made available for a specified period of time, e.g., for the duration of an event related to the content. For example, content related to a concert can be made available as a “story” for the duration of the concert. The collection management system 204 can also be responsible for posting an icon providing a notification of the existence of a particular collection to the user interface of the messaging client 104. In one implementation, the collection management system 204 can be responsible for managing a private collection of media content items that can only be viewed by a group of users selected by the creator of the private collection in the messaging system. In one implementation, the private collection of media content items can only be modified by the creator. For example, the collection management system 204 only processes and implements modifications, such as adding, deleting, or editing media content items included in the private collection received from the creator's client device 102. The private collection can also be a “private story” such that the private collection is available for a specified period of time enforced by the transient timer system 202.

[0043] In addition, the collection management system 204 further includes a curation interface 212 that allows the collection manager to manage and curate a specific content collection. For example, the curation interface 212 enables an event organizer to curate a content collection related to a specific event (e.g., deleting inappropriate content or redundant messages). In addition, the collection management system 204 employs machine vision (or image recognition technology) and content rules to automatically curate the content collection. In some examples, compensation may be paid to users for including user-generated content in the collection. In such cases, the curation management system 204 operates to automatically pay such users for using their content.

[0044] The enhancement system 206 provides various functions that enable a user to enhance (e.g., annotate or otherwise modify or edit) media content associated with a message. For example, the enhancement system 206 provides functions related to generating and publishing media overlays for messages processed by the messaging system 100. The enhancement system 206 operably supplies a media overlay or enhancement (e.g., an image filter) to the messaging client 104 based on the geolocation of the client device 102. In another example, the enhancement system 206 operably supplies a media overlay to the messaging client 104 based on other information such as the social network information of a user of the client device 102. The media overlay may include audio and visual content and visual effects. Examples of audio and visual content include pictures, text, logos, animations, and sound effects. Examples of visual effects include color overlays. The audio and visual content or visual effects may be applied to a media content item (e.g., a photo) at the client device 102. For example, the media overlay may include text or an image that can be overlaid on a photo taken by the client device 102. In another example, the media overlay includes a location marker overlay (e.g., Venice Beach), a live event name, or a merchant name overlay (e.g., Beach Café). In another example, the enhancement system 206 uses the geolocation of the client device 102 to identify a media overlay that includes the name of a merchant at the geolocation of the client device 102. The media overlay may include other markers associated with the merchant. The media overlay may be stored in the database 120 and accessed via the database server 118. In one embodiment, the enhancement system 206 generates an invitation media overlay for a private collection of media content items. The invitation overlay may include text identifying the private collection of media content items. The invitation overlay may also include an avatar associated with the user who created the private collection.

[0045] In some examples, the augmentation system 206 provides a user-based publishing platform that enables a user to select a geolocation on a map and upload content associated with the selected geolocation. The user can also specify an environment in which a particular media overlay should be provided to other users. The augmentation system 206 generates a media overlay that includes the uploaded content and associates the uploaded content with the selected geolocation.

[0046] In other examples, the augmentation system 206 provides a merchant-based publishing platform that enables a merchant to select a particular media overlay associated with a geolocation via a bidding process. For example, the augmentation system 206 associates the media overlay of the highest-bidding merchant with the corresponding geolocation for a predefined amount of time.

[0047] The map system 208 provides various geolocation functions and supports the presentation of map-based media content and messages by the messaging client 104. For example, the map system 208 enables the display on a map of user icons or avatars (e.g., stored in the profile data 308) to indicate the current or past locations of a user's "friends" in the context of the map, as well as media content (e.g., a collection of messages including photos and videos) generated by such friends. For example, a message posted by a user from a particular geolocation to the messaging system 100 can be displayed to the "friends" of the particular user at that particular location in the context of the map on the map interface of the messaging client 104. A user can also share his or her location and status information with other users of the messaging system 100 (e.g., using an appropriate status avatar) via the messaging client 104, where the location and status information is similarly displayed to the selected users in the context of the map interface of the messaging client 104.

[0048] The game system 210 provides various game functions in the context of the messaging client 104. The messaging client 104 provides a game interface that provides a list of available games that can be launched by a user in the context of the messaging client 104 and played with other users of the messaging system 100. The messaging system 100 also enables a particular user to invite such other users to participate in playing a particular game by sending an invitation from the messaging client 104 to the other users. The messaging client 104 also supports both voice messaging and text messaging (e.g., chat) in the context of playing a game, provides a leaderboard for the game, and also supports the provision of in-game rewards (e.g., coins and items).

[0049] Data Architecture

[0050] Figure 3FIG. 0 is a schematic diagram showing a data structure 300 that can be stored in a database 120 of a messaging server system 108 according to some examples. Although the contents of the database 120 are shown as including several tables, it should be understood that the data can be stored in other types of data structures (e.g., as an object-oriented database).

[0051] The database 120 includes message data stored within a message table 302. For any particular message, the message data includes at least message sender data, message recipient (or receiver) data, and a payload. Additional details regarding information that can be included in a message and included in the message data stored in the message table 302 are described below with reference to Figure 4 FIGS.

[0052] The entity table 304 stores entity data and is linked (e.g., referentially) to an entity graph 306 and profile data 308. Entities for which records are maintained within the entity table 304 can include individuals, corporate entities, organizations, objects, locations, events, etc. Any entity for which the messaging server system 108 stores data about it can be an identified entity, regardless of the entity type. Each entity is provided with a unique identifier and an entity type identifier (not shown).

[0053] The entity graph 306 stores information about the relationships and associations between entities. Such relationships can be, for example, merely social, professional (e.g., working in a common company or organization), interest-based, or activity-based.

[0054] The profile data 308 stores various types of profile data about a particular entity. Based on privacy settings specified by the particular entity, the profile data 308 can be selectively used and presented to other users of the messaging system 100. In the case where the entity is an individual, the profile data 308 includes, for example, a username, a phone number, an address, settings (e.g., notification and privacy settings), and a user-selected avatar representation (or a collection of such avatar representations). Then, a particular user can selectively include one or more of these avatar representations in the content of messages transmitted via the messaging system 100 and on a map interface displayed by the messaging client 104 to other users. The collection of avatar representations can include "status avatars" that present graphical representations of statuses or activities that a user can choose to convey at a particular time.

[0055] In the case where the entity is a group, in addition to the group name, members, and various settings of the associated group (e.g., notifications), the profile data 308 of the group can similarly include one or more avatar representations associated with the group.

[0056] The database 120 also stores enhanced data, such as overlays or filters, in the enhancement table 310. The enhanced data is associated with videos (the video data is stored in the video table 314) and images (the image data is stored in the image table 316) and is applied to the videos and images.

[0057] In one example, a filter is an overlay that is displayed as being overlaid on an image or video during presentation to a receiving user. Filters can be of various types, including filters selected by a user from a set of filters presented to the sending user by the messaging client 104 when the sending user is composing a message. The filters selected by the user can include an invite media overlay associated with a private collection of media content items.

[0058] Other types of filters include geolocation filters (also known as geo - filters), which can be presented to the sending user based on geolocation. For example, specific to a nearby or special location geolocation filters can be presented by the messaging client 104 within the user interface based on geolocation information determined by the global positioning system (GPS) unit of the client device 102.

[0059] Another type of filter is a data filter, which can be selectively presented to the sending user by the messaging client 104 based on other input or information collected by the client device 102 during the message creation process. Examples of data filters include the current temperature at a specific location, the current speed at which the sending user is traveling, the battery life of the client device 102, or the current time.

[0060] Other enhanced data that can be stored within the image table 316 includes augmented reality content items (e.g., corresponding to an applied lens or augmented reality experience). Augmented reality content items can be real - time special effects and sounds that can be added to an image or video.

[0061] As described above, enhanced data includes augmented reality content items, overlays, image transformations, AR images, and similar items that refer to modifications that can be applied to image data (e.g., video or images). This includes real-time modifications that modify an image when the image is captured using device sensors (e.g., one or more camera devices) of the client device 102 and then displayed on the screen of the client device 102 in the modified case. This also includes modifications to stored content (e.g., video clips in a gallery that can be modified). For example, in the client device 102 that has access to multiple augmented reality content items, a user can use a single video clip with multiple augmented reality content items to see how different augmented reality content items would modify the stored clip. For example, by selecting different augmented reality content items for the same content, multiple augmented reality content items applying different pseudo-random motion models can be applied to the same content. Similarly, real-time video capture can be used with the shown modifications to show how the video image currently captured by the sensors of the client device 102 would modify the captured data. Such data can be simply displayed on the screen without being stored in memory, or the content captured by the device sensors can be recorded and stored in memory with or without modification (or both). In some systems, a preview feature can show how different augmented reality content items would look within different windows on the display simultaneously. For example, this can enable viewing multiple windows with different pseudo-random animations on the display at the same time.

[0062] Accordingly, systems that use data of augmented reality content items and various other such transformation systems that use the data to modify content can involve the detection of objects (e.g., faces, hands, bodies, cats, dogs, surfaces, objects, etc.), the tracking of such objects as they leave, enter, and move around within the field of view of a video frame, and the modification or transformation of such objects when they are being tracked. In various embodiments, different methods can be used to implement such transformations. Some examples can involve generating a three-dimensional mesh model of one or more objects and using the transformation and animated textures of the model within the video to implement the transformation. In other examples, the tracking of points on an object can be used to place an image or texture (which can be two-dimensional or three-dimensional) at the tracked locations. In further examples, neural network analysis of video frames can be used to place an image, model, or texture within the content (e.g., an image or frame of a video). Accordingly, augmented reality content items refer both to the images, models, and textures used to create transformations within content and to the additional modeling and analysis information required to implement such transformations using object detection, tracking, and placement.

[0063] Real-time video processing can be performed using any kind of video data (e.g., video streams, video files, etc.) stored in the memory of any kind of computerized system. For example, a user can load a video file and save it in the device's memory, or can use the device's sensors to generate a video stream. Additionally, computer animation models can be used to process any object, such as parts of a human face and body, animals, or inanimate objects (e.g., chairs, cars, or other objects).

[0064] In some examples, when a specific modification is selected along with the content to be transformed, the element to be transformed is identified by the computing device, and then, if the element to be transformed is present in a frame of the video, the element to be transformed is detected and tracked. The elements of the object are modified according to the modification request, thereby transforming the frame of the video stream. For different kinds of transformations, the transformation of the frame of the video stream can be performed by different methods. For example, for a frame transformation that mainly refers to the variation form of the elements of an object, the feature points of each element of the object are calculated (e.g., using an active shape model (ASM) or other known methods). Then, a grid based on the feature points is generated for each of at least one element of the object. This grid is used for the subsequent stage of tracking the elements of the object in the video stream. During the tracking process, the mentioned grid of each element is aligned with the position of each element. Then, additional points are generated on the grid. A first set of first points is generated for each element based on the modification request, and a set of second points is generated for each element based on this set of first points and the modification request. Then, the frame of the video stream can be transformed by modifying the elements of the object based on this set of first points, this set of second points, and the grid. In such a method, the background of the modified object can also be changed or distorted by tracking and modifying the background.

[0065] In some examples, a transformation that uses the elements of an object to change some regions of the object can be performed by calculating the feature points of each element of the object and generating a grid based on the calculated feature points. Points are generated on the grid, and then various regions are generated based on these points. Then, the elements of the object are tracked by aligning the regions of each element with the position of each of at least one element, and the attributes of the regions can be modified based on the modification request, thereby transforming the frame of the video stream. Depending on the specific modification request, the attributes of the mentioned regions can be transformed in different ways. Such modifications can involve: changing the color of the region; removing at least part of the region from the frame of the video stream; including one or more new objects in the region based on the modification request; and modifying or distorting the region or the elements of the object. In various embodiments, any combination of such modifications or other similar modifications can be used. For some models to be animated, some feature points can be selected as control points for determining the entire state space of the options for model animation.

[0066] In some examples of computer animation models that use face detection to transform image data, a specific face detection algorithm (e.g., Viola-Jones) is used to detect faces in an image. Then, an Active Shape Model (ASM) algorithm is applied to the face region of the image to detect facial feature reference points.

[0067] In other examples, other methods and algorithms suitable for face detection can be used. For example, in some embodiments, landmarks are used to locate features, where a landmark represents a distinguishable point that exists in most images under consideration. For example, for face landmarks, the location of the left eye pupil can be used. If the initial landmark is not recognizable (e.g., if a person has an eye patch), secondary landmarks can be used. Such a landmark recognition process can be used for any such object. In some examples, a set of landmarks forms a shape. The shape can be represented as a vector using the coordinates of the points in the shape. One shape is aligned with another using a similarity transformation (allowing translation, scaling, and rotation) that minimizes the mean Euclidean distance between the shape points. The average shape is the average of the aligned training shapes.

[0068] In some examples, a search for landmarks begins from an average shape aligned with the position and size of the face determined by a full-face detector. Then, such a search repeats the steps of: suggesting a tentative shape by adjusting the positioning of shape points through template matching of the image texture around each point, and then conforming the tentative shape to a global shape model until convergence occurs. In some systems, individual template matches are unreliable, and the shape model pools the results of weak template matches to form a stronger overall classifier. The entire search is repeated at each level of an image pyramid from a coarse resolution to a fine resolution.

[0069] The transformation system can capture an image or video stream on a client device (e.g., client device 102) and perform complex image manipulations locally on client device 102 while maintaining an appropriate user experience, computation time, and power consumption. Complex image manipulations can include size and shape changes, emotion transfer (e.g., changing a face from a frown to a smile), state transfer (e.g., aging a subject, reducing apparent age, changing gender), style transfer, application of graphical elements, and any other suitable image or video manipulation implemented by a convolutional neural network that has been configured to execute efficiently on client device 102.

[0070] In some examples, a computer animation model for transforming image data can be used by a system in which a user can capture an image or video stream (e.g., a selfie) using a client device 102 having a neural network operating as part of a messaging client 104 operating on the client device 102. A transformation system operating within the messaging client application 104 determines the presence of a face within the image or video stream and provides a modification icon associated with the computer animation model to transform the image data, or the computer animation model can be presented as being associated with the interfaces described herein. The modification icon includes a change that can be the basis for modifying the user's face within the image or video stream as part of a modification operation. Once the modification icon is selected, the transformation system initiates a process of converting the user's image to reflect the selected modification icon (e.g., generating a smiling face on the user). Once the image or video stream is captured and the specified modification is selected, the modified image or video stream can be presented in a graphical user interface displayed on the client device 102. The transformation system can implement a complex convolutional neural network on a portion of the image or video stream to generate and apply the selected modification. That is, once the modification icon is selected, the user can capture an image or video stream and the result of the modification can be presented in real time or near real time. Additionally, when a video stream is being captured, the modification can be persistent and the selected modification icon remains toggled. A machine-taught neural network can be used to implement such modifications.

[0071] A graphical user interface presenting the modifications performed by the transformation system can supply additional interaction options to the user. Such options can be based on the interface used to initiate content capture and selection for a particular computer animation model (e.g., initiated from a content creator user interface). In various embodiments, the modification can be persistent after an initial selection of the modification icon. The user can turn the modification on or off and store it for later viewing or browsing to other areas of the imaging application by tapping or otherwise selecting the face modified by the transformation system. In the case where multiple faces are modified by the transformation system, the user can globally turn the modification on or off by tapping or selecting an individual face modified and displayed within the graphical user interface. In some embodiments, individual faces within a group of multiple faces can be modified separately, or such modifications can be toggled individually by tapping or selecting each individual face or a series of individual faces displayed within the graphical user interface.

[0072] The story table 312 stores data regarding a collection of messages, along with associated image, video, or audio data, which are compiled into a collection (e.g., a story or a gallery). The creation of a particular collection can be initiated by a particular user (e.g., each user whose record is maintained in the entity table 304). A user can create a "personal story" in the form of a collection of content that has been created and sent / broadcast by that user. To this end, the user interface of the messaging client 104 can include user-selectable icons to enable the sending user to add specific content to his or her personal story.

[0073] The collection can also constitute a "live story" as a collection of content from multiple users, which is created manually, automatically, or using a combination of manual and automatic techniques. For example, a "live story" can constitute a curated stream of user-submitted content from various locations and events. Options can be presented, for example, via the user interface of the messaging client 104 to users of its client devices whose location services are enabled and who are at a public location event at a particular time, to contribute content to a particular live story. A live story can be identified to a user by the messaging client 104 based on his or her location. The end result is a "live story" told from a community perspective.

[0074] Another type of content collection is called a "location story", which enables users whose client devices 102 are located within a particular geolocation (e.g., on a college or university campus) to contribute to a particular collection. In some embodiments, contributing to a location story may require a second degree of authentication to verify that the end user belongs to a particular organization or other entity (e.g., is a student on a university campus).

[0075] As mentioned above, the video table 314 stores video data, which, in one example, is associated with messages whose records are maintained in the message table 302. Similarly, the image table 316 stores image data associated with messages whose message data is stored in the entity table 304. The entity table 304 can associate various enhancements from the enhancement table 310 with the various images and videos stored in the image table 316 and the video table 314.

[0076] Data Communication Architecture

[0077] Figure 4FIG. is a schematic diagram showing the structure of a message 400 according to some examples, which is generated by a messaging client 104 for transmission to another messaging client 104 or a messaging server 114. The content of a particular message 400 is used to populate a message table 302 stored in a database 120, which can be accessed by the messaging server 114. Similarly, the content of the message 400 is stored in memory as "in-transit" or "in-flight" data of the client device 102 or the application server 112. The message 400 is shown as including the following example components:

[0078] · Message identifier 402: A unique identifier that identifies the message 400.

[0079] · Message text payload 404: Text to be generated by a user via a user interface of the client device 102 and included in the message 400.

[0080] · Message image payload 406: Image data captured by a camera device component of the client device 102 or retrieved from a memory component of the client device 102 and included in the message 400. The image data for a sent or received message 400 can be stored in an image table 316.

[0081] · Message video payload 408: Video data captured by a camera device component or retrieved from a memory component of the client device 102 and included in the message 400. The video data for a sent or received message 400 can be stored in a video table 314.

[0082] · Message audio payload 410: Audio data captured by a microphone or retrieved from a memory component of the client device 102 and included in the message 400.

[0083] · Message enhancement data 412: Enhancement data (e.g., filters, stickers, or other annotations or enhancements) representing enhancements to be applied to the message image payload 406, message video payload 408, or message audio payload 410 of the message 400. The enhancement data for a sent or received message 400 can be stored in an enhancement table 310.

[0084] · Message duration parameter 414: A parameter value indicating, in seconds, the amount of time for which the content of the message (e.g., message image payload 406, message video payload 408, message audio payload 410) is to be presented to or accessible by a user via the messaging client 104.

[0085] · Message Geolocation Parameter 416: Geolocation data (e.g., latitude coordinates and longitude coordinates) associated with the content payload of a message. Multiple Message Geolocation Parameter 416 values can be included in the payload, with each of these parameter values associated with a content item included in the content (e.g., a specific image that has entered the message image payload 406, or a specific video in the message video payload 408).

[0086] · Message Story Identifier 418: An identifier value that identifies one or more content collections (e.g., the "stories" identified in the story table 312), where a specific content item in the message image payload 406 of message 400 is associated with one or more content collections. For example, the identifier value can be used to associate each of multiple images within the message image payload 406 with multiple content collections.

[0087] · Message Tag 420: Each message 400 can be tagged with multiple tags, with each of such multiple tags indicating a theme of the content included in the message payload. For example, in the case where a specific image included in the message image payload 406 depicts an animal (e.g., a lion), a tag value can be included within the message tag 420 indicating the relevant animal. The tag value can be manually generated based on user input, or can be automatically generated using, for example, image recognition.

[0088] · Message Sender Identifier 422: An identifier (e.g., a messaging system identifier, an email address, or a device identifier) that indicates the user of the client device 102 on which message 400 is generated and from which message 400 is sent.

[0089] · Message Recipient Identifier 424: An identifier (e.g., a messaging system identifier, an email address, or a device identifier) that indicates the user of the client device 102 to which message 400 is addressed.

[0090] The content (e.g., values) of the various components of message 400 can be pointers to the locations in the tables where the content data values are stored. For example, the image value in the message image payload 406 can be a pointer to a location within the image table 316 (or an address of a location within the image table 308). Similarly, the value within the message video payload 408 can point to data stored in the video table 314, the value stored in the message enhancement 412 can point to data stored in the enhancement table 310, the value stored in the message story identifier 418 can point to data stored in the story table 312, and the values stored in the message sender identifier 422 and the message recipient identifier 424 can point to user records stored in the entity table 304.

[0091] Although the described flowcharts may show operations as a sequential process, many of the operations can be performed in parallel or simultaneously. In addition, the order of the operations can be rearranged. The process terminates when its operations are completed. The process can correspond to a method, program, algorithm, etc. The operations of the method can be performed in whole or in part, can be combined with some or all of the operations in other methods, and can be executed by any number of different systems such as the systems described herein or any part thereof such as a processor included in any system.

[0092] Time-based access restriction architecture

[0093] Figure 5 is a schematic diagram showing an access restriction process 500 according to which access to content (e.g., a transient message 502 and a multimedia payload of associated data) or a collection of content (e.g., a transient message group 504) can be time-restricted (e.g., transient).

[0094] The transient message 502 is shown as being associated with a message duration parameter 506, the value of which determines the amount of time that the messaging client 104 will display the transient message 502 to the recipient user of the transient message 502. In one embodiment, depending on the amount of time specified by the sending user using the message duration parameter 506, the receiving user can view the transient message 502 for up to 10 seconds at most.

[0095] The message duration parameter 506 and the message recipient identifier 424 are shown as inputs to a message timer 512, which is responsible for determining the amount of time to display the transient message 502 to a specific recipient user identified by the message recipient identifier 424. In particular, the transient message 502 is displayed to the relevant recipient user only for the time period determined by the value of the message duration parameter 506. The message timer 512 is shown as providing an output to a more general transient timer system 202, which is responsible for the overall timing of displaying content (e.g., the transient message 502) to the receiving user.

[0096] Figure 5 The transient message 502 shown in is included within a transient message group 504 (e.g., a collection of messages in a personal story or an event story). The transient message group 504 has an associated group duration parameter 508, the value of which determines the duration for which the transient message group 504 is presented and accessible by the users of the messaging system 100. For example, the group duration parameter 508 can be the duration of a concert, where the transient message group 504 is a collection of content related to the concert. Alternatively, when setting up and creating the transient message group 504, the user (all users or a curator user) can specify the value of the group duration parameter 508.

[0097] In addition, each transient message 502 within the transient message group 504 has an associated group participation parameter 510, and the value of the group participation parameter 510 determines the duration for which the transient message 502 will be accessible within the context of the transient message group 504. Thus, a particular transient message group 504 can "expire" and become inaccessible within the context of the transient message group 504 before the transient message group 504 itself expires according to the group duration parameter 508. The group duration parameter 508, the group participation parameter 510, and the message recipient identifier 424 each provide an input to a group timer 514, which is operable to first determine whether a particular transient message 502 of the transient message group 504 will be displayed to a particular receiving user, and if so, for how long. Note that due to the message recipient identifier 424, the transient message group 504 also knows the identity of the specific receiving user.

[0098] Thus, the group timer 514 is operable to control the overall expiration time of the associated transient message group 504 and the individual transient messages 502 included within the transient message group 504. In one embodiment, each transient message 502 within the transient message group 504 remains viewable and accessible for a period of time specified by the group duration parameter 508. In another example, within the context of the transient message group 504, a particular transient message 502 can expire based on the group participation parameter 510. Note that even within the context of the transient message group 504, the message duration parameter 506 can still determine the duration for which a particular transient message 502 is displayed to the receiving user. Thus, the message duration parameter 506 determines the duration for which a particular transient message 502 is displayed to the receiving user, regardless of whether the receiving user views the transient message 502 within or outside the context of the transient message group 504.

[0099] The transient timer system 202 can also operably remove a particular transient message 502 from the transient message group 504 based on determining that the particular transient message 502 has exceeded the associated group participation parameter 510. For example, when the sending user has established a group participation parameter 510 of 24 hours from the time of posting, the transient timer system 202 will remove the associated transient message 502 from the transient message group 504 after the specified 24 hours. The transient timer system 202 also operates to remove the transient message group 504 when the group participation parameter 510 has expired for each transient message 502 within the transient message group 504, or when the transient message group 504 itself has expired according to the group duration parameter 508.

[0100] In certain usage scenarios, the creator of a specific ephemeral message group 504 can specify an indefinite group duration parameter 508. In such cases, the expiration of the group participation parameter 510 for the last remaining ephemeral message 502 within the ephemeral message group 504 will determine when the ephemeral message group 504 itself expires. In such cases, a new ephemeral message 502 with a new group participation parameter 510 added to the ephemeral message group 504 effectively extends the lifespan of the ephemeral message group 504 to be equal to the value of the group participation parameter 510.

[0101] In response to the ephemeral timer system 202 determining that the ephemeral message group 504 has expired (e.g., is no longer accessible), the ephemeral timer system 202 communicates with the messaging system 100 (and in particular, for example, the messaging client 104) such that a marker (e.g., an icon) associated with the relevant ephemeral message group 504 is no longer displayed within the user interface of the messaging client 104. Similarly, when the ephemeral timer system 202 determines that the message duration parameter 506 for a specific ephemeral message 502 has expired, the ephemeral timer system 202 causes the messaging client 104 to no longer display a marker (e.g., an icon or text identifier) associated with the ephemeral message 502.

[0102] Invitation media overlay

[0103] In one embodiment, a first user associated with the first client device 102 can generate a private collection (e.g., a private story) of media content items to be shared only with a selected group of users (e.g., close friends). To invite users to join the group that can view his private story, an invitation media overlay (e.g., a private story sticker) can be overlaid on each media content item shared as a "story" with the selected group of users or shared as a direct message with each user in the selected group of users. The selected group of users (e.g., the recipients) can join the private story by selecting the invitation media overlay.

[0104] Figure 6 A process 600 for generating an invitation media overlay for a private collection of media content items is shown in accordance with one embodiment. The operations of the process 600 can be performed by any number of different systems, such as by the messaging server 114 or the messaging client 104 described herein or any part thereof, such as a processor included in any system.

[0105] At operation 602, the processor receives a first media content item from the first client device 102 associated with the first user. The media content item can be an image, a picture, a video, text, or any combination thereof. The first user can use a camera device included in the first client device 102 to capture the media content item. Figure 7shows a user interface 700 that can be displayed on a first client device 102. As Figure 7 shown, the media content item 702 is a picture or photograph of a cat. The user interface 700 also includes a sticker menu icon 704. When a first user selects the sticker menu icon 704, Figure 8 the user interface 800 in

[0106] is displayed by the first client device 102. The user interface 800 includes different media overlays that can be applied to enhance the media content item 702. Figure 8 In operation 604, the processor receives, from the first client device 102, a selection of an invitation media overlay to be applied to a first media content item. The invitation media overlay layer can be associated with a private collection of media content items. In

[0107] one embodiment, the processor can cause the privacy option to be displayed by the first client device 102. The processor can also cause a text input item to be displayed by the first client device 102. As Figure 9 shown, in response to a selection of the invitation media overlay option 802, a user interface 900 can be displayed by the first client device 102. The user interface 900 can include a text input item 902, a privacy option 904, and a share option 906.

[0108] When the first user selects the privacy option 904, the processor receives, from the first client device 102, a selection of the privacy option 904. In response to receiving the selection of the privacy option 904 from the first client device 102, the processor establishes that the private collection of media content items can only be modified by the first client device 102.

[0109] When the first user selects the share option 906, the processor receives, from the first client device 102, a selection of the share option 906 and establishes that the collection of media content items is a shared collection of media content items. The shared collection of media content items can be modified by other users such as selected users in a group.

[0110] AsFigure 9 As shown, the private option 904 and the share option 906 can be selectable radio buttons. In other embodiments, the private option 904 and the share option 906 can be selectable items such as text, links, icons, images, etc.

[0111] The processor can also receive text from the first client device 102 via the text input item 902 in the user interface 900. As Figure 10 shown, the user interface 1000 that can be displayed by the first client device 102 shows that the first user has entered the text "Justin's cat" in the text input item 902. This text can be a title related to a private collection of media content items.

[0112] At operation 606, the processor generates a modified first media content item by overlaying an invitation media overlay on the first media content item.

[0113] At Figure 11 shown, the user interface 1100 that can be displayed by the first client device 102 is shown. Once the first user enters the text "Justin's cat" in the text input item 902 and selects the private option 904, the user interface 1100 is displayed by the first client device 102, and the user interface 1100 includes the modified media content item 1102. As Figure 11 shown, the modified media content item 1102 includes an invitation media overlay 1104 overlaid on the media content item 702. The invitation media overlay 1104 can include the text entered in the text input item 902 (e.g., "Justin's cat"). In one embodiment, the invitation media overlay 1104 can also include an icon that includes an avatar of the creator of the private collection (e.g., the first user). To indicate that the story or collection is a private collection, as shown in the invitation media overlay 1104, the icon can also include an image of a lock.

[0114] At operation 608, the processor generates a private collection of media content items. The private collection of media content items includes the modified first media content item (e.g., the modified media content item 1102). In one embodiment, the private collection of media content items includes a plurality of media content items received from the first client device 102. In one embodiment, the processor receives a second media content item from the first client device 102.

[0115] At operation 610, the processor receives a selection of a second user associated with a second client device 102 from a first client device 102. The second user is selected by the first user to be included in a selected user group (e.g., a private group) that can view a private collection. The private group can include one or more users associated with one or more client devices 102.

[0116] At operation 612, the processor causes the modified first media content item to be displayed by the second client device 102.

[0117] In one embodiment, the second client device 102 can receive the modified first modified media content item 1102 as a story or collection. For example, the processor can cause the second client device 102 to display a story icon associated with the modified media content item 1102 from the first user. The story icon for the first user's private collection can be included among a plurality of story icons associated with a plurality of users (e.g., the second user's contacts or friends) connected to the second user on the messaging system 100. In this embodiment, the modified media content item 1102 from the first user is broadcast as a story available for a limited amount of time to the users in the private group. When the second user selects the story icon for the first user's private collection, Figure 14 the user interface 1400 in can be displayed by the second client device 102. The user interface 1400 includes the modified media content item 1102 with an invitation media overlay 1104. The user interface 1400 also includes invitation response selectable items 1402. The second user can select the invitation media overlay 1104 or an invitation response selectable item 1402 to join the private story or collection (e.g., "Justin's Cat"). In other words, the second user can join the private group that can access and view the media content item.

[0118] When the second user selects the invitation media overlay 1104, at operation 614, the processor receives a selection of the invitation media overlay from the second client device 102. In one embodiment, as Figure 15As shown, when the second user selects the invitation response option 1402, the processor causes the user interface 1500 to be displayed on the second client device 102. The user interface 1500 includes an invitation details display 1502, which can be a pop-up or scroll-up notification overlaying the user interface 1400. The invitation details display 1502 can include the information included in the invitation media overlay 1104, such as text (e.g., "Justin's cat") and an icon with the avatar of the first user. The invitation details display 1502 can also include text inviting the second user to join a story or collection. For example, the text can indicate that the first user invites the second user to view a private collection of media content items (e.g., "Justin invites you to see her private story!"). The invitation details display 1502 also includes an invitation details response option 1504. The second user can select the invitation details response option 1504 to respond to the invitation to join the private story. In one embodiment, when the second user selects the invitation details response option 1504, the processor can also receive a selection of the invitation media overlay from the second client device 102 in operation 614.

[0119] In another embodiment, the second client device 102 can receive a modified first modified media content item 1102 from the first client device 102 as a direct message. When the modified media content item 1102 is received as a direct message, Figure 16 the user interface 1600 in can be displayed by the second client device 102. The user interface 1600 includes a message notification corresponding to the message received from the first user (e.g., Justin). The message notification includes a direct message notification 1602 and a direct message invitation option 1604. When the second user selects the direct message notification 1602, the user interface 1400 including the modified media content item 1102 can be displayed by the second client device 102. Alternatively, when the second user selects the direct message invitation option 1604, the user interface 1700 can be displayed on the second client device 102. The user interface 1700 includes an invitation details display 1502 overlaying the user interface 1600. The invitation details display 1502 in the user interface 1700 can also include an invitation details response option 1504.

[0120] At operation 616, the processor causes a private collection of media content items to be displayed by the second client device 102. In one embodiment, the private collection is broadcast as a story available for a limited amount of time to the users in the private group. In one embodiment, the second client device 102 can receive a story notification associated with the private collection. The story notification indicates to the second user that the private collection includes media content items that have not been viewed by the second user.

[0121] When a first user adds a second media content item to a private collection, the processor may receive the second media content item from the first client device 102 and update the private collection of media content items to include the second media content item. The processor may also cause the updated private collection of media content items to be displayed by the second client device 102.

[0122] Figure 7 A user interface 700 is shown that is displayed on the client device 102 according to one embodiment. The user interface 700 may be displayed on the first client device 102 that is creating a media content item for a private collection. The media content item 702 may be an image, a photo, an audio recording, a video, text, or any combination thereof. The media content item 702 may be captured by the first client device 102 using a camera device included in or coupled to the first client device 102. The user interface 700 includes the media content item 702 and a plurality of icons for enhancing the media content item 702 with text, audio, editing, drawing, animation, stickers, special effects, and the like. The sticker menu icon 704 is one of the plurality of icons in the user interface 700. The sticker menu icon 704 is used to activate the sticker menu user interface 800.

[0123] Figure 8 A user interface 800 is shown that is displayed on the client device 102 according to one embodiment. The user interface 800 may be displayed on the first client device 102 that is creating a media content item for a private collection. The user interface 800 includes different media overlays that may be applied to enhance the media content item 702. The media overlays may include a plurality of images (e.g., stickers), which may be static or animated (e.g., images of cats, bears, snails, turtles, etc.). The media overlays may also include an invite media overlay option 802. The invite media overlay option 802 is associated with a sticker that invites a recipient user to join the collection of media content items. In one embodiment, the sticker is a private story sticker that invites the recipient to join the private collection of media content items.

[0124] Figure 9 A user interface 900 is shown that is displayed on the first client device 102 according to one embodiment. The user interface 900 includes a text input item 902, a private option 904, and a share option 906. The text input item 902 may receive text input by the first user, which is the title of the private collection or story. The text may also be included in a private story sticker (e.g., invite media overlay 1104) that is being generated.

[0125] The first user has an alternative option to select either the private option 904 or the share option 906. Selecting the private option 904 makes the story a private collection such that only the first user has permission to modify the private collection and the content of the private collection. Selecting the share option 906 makes the story a shared collection such that users in the private group can modify the shared collection and the content of the shared collection.

[0126] Figure 10 Shown is a user interface 1000 displayed on a first client device 102 according to one embodiment. The user interface 1000 shows the first user entering a title for the private collection (e.g., "Justin's Cat") in the text input item 902, which is also the text in the invitation media overlay 1104.

[0127] Figure 11 Shown is a user interface 1100 displayed on a first client device 102 according to one embodiment. Once text is entered in the text input item 902 in the user interface 900 and the private option 904 is selected to generate the invitation media overlay 1104, the user interface 1100 is displayed on the first client device 102. The user interface 1100 includes a modified media content item 1102 that includes the invitation media overlay 1104 overlaid on the media content item 702.

[0128] Figure 12 Shown is a user interface 1200 displayed on a first client device 102 according to one embodiment.

[0129] The user interface 1200 shows a situation when the first user is generating a media content item to add to an existing private collection. When the first user enters a portion of text (e.g., "sna") in the text input item 902, multiple collection options 1202 with titles including that portion of text (e.g., "Snacks", "Snap Doggies", etc.) are displayed in the user interface 1200.

[0130] In another example, if the first user enters a portion of text "Justin", the collection options associated with the private collection (e.g., "Justin's Cat") may appear in the multiple collection options 1202 in the user interface 1200. In this example, the first user can add an additional media content item to the private collection "Justin's Cat" by selecting the collection option associated with the private collection (e.g., "Justin's Cat").

[0131] Figure 13 Shown is a user interface 1300 displayed on a first client device 102 according to one embodiment.

[0133] Figure 14 is displayed. User interface 1300 includes a modified media content item 1302, which includes an invitation media overlay 1304 covering the media content item 702. The invitation media overlay 1304 includes the text "snacks" and is associated with a private collection titled "snacks".

[0134] When a second user receives the modified media content item 1102 as a story, the user interface 1400 is displayed to the second user. The modified media content item 1102 is received as a story when the first client device 102 broadcasts the modified media content item 1102 to a private group and the story is associated with a story icon on each user's client device 102 in the private group.

[0135] When the second user activates the Figure 16 direct message notification 1602 associated with the modified media content item 1102 in

[0136] the user interface 1400 can also be displayed by the second client device 102.

The invitation details display 1502 can also include text for inviting a second user to join a story or collection. For example, the text can indicate that the first user invites the second user to view a private collection of media content items (e.g., "Justin invites you to see her private story!"). The invitation details display 1502 also includes invitation details response options 1504. The second user can select the invitation details response options 1504 to respond to the invitation to join the private story.

[0143] Machine architecture

[0144] Figure 18is an illustrative representation of a machine 1100, in which instructions 1808 (e.g., software, program, application, applet, app, or other executable code) can be executed to cause the machine 1800 to perform any one or more of the methods discussed herein. For example, the instructions 1808 can cause the machine 1800 to perform any one or more of the methods described herein. The instructions 1808 transform the general, non-programmed machine 1800 into a particular machine 1800 programmed to perform the described and illustrated functions in the described manner. The machine 1800 can operate as a stand-alone device or can be coupled (e.g., networked) to other machines. In a networked deployment, the machine 1800 can operate in the capacity of a server machine or a client machine in a server-client network environment, or as a peer machine in a peer-to-peer (or distributed) network environment. The machine 1800 can include, but is not limited to: server computers, client computers, personal computers (PCs), tablet computers, laptop computers, netbooks, set-top boxes (STBs), personal digital assistants (PDAs), entertainment media systems, cellular telephones, smart phones, mobile devices, wearable devices (e.g., smart watches), smart home devices (e.g., smart appliances), other smart devices, network devices, network routers, network switches, network bridges, or any machine capable of executing the instructions 1808 that specify actions to be taken by the machine 1800, either sequentially or otherwise. Further, while only a single machine 1800 is shown, the term "machine" shall also be taken to include a collection of machines that individually or jointly execute the instructions 1808 to perform any one or more of the methods discussed herein. For example, the machine 1800 can include any one of the client devices 102 or a number of server devices forming part of the messaging server system 108. In some examples, the machine 1800 can also include both a client system and a server system, where certain operations of a particular method or algorithm are executed on the server side and where certain operations of a particular method or algorithm are executed on the client side.

[0145] Machine 1800 may include a processor 1802, a memory 1804, and input / output (I / O) components 638 that may be configured to communicate with each other via a bus 1840. In an example, the processor 1802 (e.g., a central processing unit (CPU), a reduced instruction set computing (RISC) processor, a complex instruction set computing (CISC) processor, a graphics processing unit (GPU), a digital signal processor (DSP), an application specific integrated circuit (ASIC), a radio frequency integrated circuit (RFIC), another processor, or any suitable combination thereof) may include, for example, a processor 1806 and a processor 1810 that execute instructions 1808. The term "processor" is intended to include multi-core processors, which may include two or more independent processors (sometimes referred to as "cores") that may execute instructions simultaneously. Although Figure 18 multiple processors 1802 are shown, machine 1800 may include a single processor with a single core, a single processor with multiple cores (e.g., a multi-core processor), multiple processors with a single core, multiple processors with multiple cores, or any combination thereof.

[0146] The memory 1804 includes a main memory 1812, a static memory 1814, and a storage unit 1816, all of which may be accessed by the processor 1802 via the bus 1840. The main memory 1804, the static memory 1814, and the storage unit 1816 store instructions 1808 that implement any one or more of the methods or functions described herein. The instructions 1808 may also reside, completely or partially, within the main memory 1812, within the static memory 1814, within the machine-readable medium 1818 of the storage unit 1816, within at least one of the processors 1802 (e.g., within a cache memory of the processor), or within any suitable combination thereof during execution by the machine 1800.

[0147] The I / O components 1838 may include various components for receiving input, providing output, generating output, transmitting information, exchanging information, capturing measurement results, etc. The specific I / O components 1838 included in a particular machine will depend on the type of the machine. For example, a portable machine such as a mobile phone may include a touch input device or other such input mechanism, while a headless server machine may not include such a touch input device. It should be appreciated that the I / O components 1838 may include Figure 18Many other components not shown. In various examples, the I / O component 1838 can include a user output component 1824 and a user input component 1826. The user output component 1824 can include visual components (e.g., displays such as plasma display panels (PDPs), light emitting diode (LED) displays, liquid crystal displays (LCDs), projectors, or cathode ray tubes (CRTs)), acoustic components (e.g., speakers), haptic components (e.g., vibration motors, resistance mechanisms), other signal generators, etc. The user input component 1826 can include alphanumeric input components (e.g., keyboards, touchscreens configured to receive alphanumeric input, optical keyboards, or other alphanumeric input components), point-based input components (e.g., mice, touchpads, trackballs, joysticks, motion sensors, or other pointing instruments), haptic input components (e.g., physical buttons, touchscreens that provide the location and / or force of a touch or touch gesture, or other haptic input components), audio input components (e.g., microphones), etc.

[0148] In another example, the I / O component 1838 can include: a biometric component 1828, a motion component 1830, an environmental component 1832, or a location component 1834, as well as a variety of other components. For example, the biometric component 1828 includes components for detecting expressions (e.g., hand expressions, facial expressions, voice expressions, body postures, or eye tracking), measuring biometric signals (e.g., blood pressure, heart rate, body temperature, sweating, or brain waves), identifying people (e.g., voice recognition, retina recognition, face recognition, fingerprint recognition, or electroencephalogram-based recognition), etc. The motion component 1830 includes acceleration sensor components (e.g., accelerometers), gravity sensor components, rotational sensor components (e.g., gyroscopes).

[0149] The environmental component 1832 includes, for example: one or more camera devices (with still image / photo and video capabilities), lighting sensor components (e.g., photometers), temperature sensor components (e.g., one or more thermometers that detect ambient temperature), humidity sensor components, pressure sensor components (e.g., barometers), acoustic sensor components (e.g., one or more microphones that detect background noise), proximity sensor components (e.g., infrared sensors that detect nearby objects), gas sensors (e.g., gas detection sensors that detect the concentration of hazardous gases for safety or measure pollutants in the atmosphere), or other components that can provide an indication, measurement, or signal corresponding to the surrounding physical environment.

[0150] Regarding the imaging device, the client device 102 may have an imaging device system that includes, for example, a front imaging device on the front surface of the client device 102 and a rear imaging device on the rear surface of the client device 102. The front imaging device may be used, for example, to capture still images and videos of the user of the client device 102 (e.g., "selfies"), and the still images and videos may then be enhanced with the above-described enhancement data (e.g., filters). For example, the rear imaging device may be used to capture still images and videos in a more conventional imaging device mode, and these images are similarly enhanced with the enhancement data. In addition to the front imaging device and the rear imaging device, the client device 102 may further include a 360° imaging device for capturing 360° photos and videos.

[0151] In addition, the imaging device system of the client device 102 may include a dual rear imaging device (e.g., a main imaging device and a depth sensing imaging device), or even a triple, quadruple, or quintuple rear imaging device configuration on the front and rear sides of the client device 102. For example, these multi-imaging device systems may include a wide-angle imaging device, an ultra-wide-angle imaging device, a telephoto imaging device, a macro imaging device, and a depth sensor.

[0152] The location component 1834 includes a positioning sensor component (e.g., a GPS receiver component), an altitude sensor component (e.g., an altimeter or barometer that detects air pressure, and altitude can be obtained based on the air pressure), an orientation sensor component (e.g., a magnetometer), etc.

[0153] Various techniques can be used to implement communication. The I / O component 1838 also includes a communication component 1836 that is operable to couple the machine 1800 to the network 1820 or the device 1822 via a corresponding coupling or connection. For example, the communication component 1836 may include a network interface component or other suitable device that interfaces with the network 1820. In another example, the communication component 1836 may include a wired communication component, a wireless communication component, a cellular communication component, a near field communication (NFC) component, components (e.g., low power), Wi- components, and other communication components that provide communication via other modalities. The device 1822 may be another machine or any of various peripheral devices (e.g., a peripheral device coupled via USB).

[0154] In addition, the communication component 1836 can detect an identifier, or include components operable to detect an identifier. For example, the communication component 1836 can include a radio frequency identification (RFID) tag reader component, an NFC smart tag detection component, an optical reader component (e.g., an optical sensor for detecting one-dimensional barcodes such as Universal Product Code (UPC) barcodes, multi-dimensional barcodes such as Quick Response (QR) codes, Aztec codes, Data Matrix, Dataglyph, MaxiCode, PDF417, Ultra Code, UCC RSS-2D barcodes, and other optical codes), or an acoustic detection component (e.g., a microphone for identifying a tagged audio signal). In addition, various information can be obtained via the communication component 1836, such as a location via Internet Protocol (IP) geolocation, a location via Wi- signal triangulation, a location via detecting an NFC beacon signal, etc., where the NFC beacon signal can indicate a specific location.

[0155] Various memories (e.g., main memory 1812, static memory 1814, and the memory of the processor 1802) and the storage unit 1816 can store one or more sets of instructions and data structures (e.g., software) implemented or used by any one or more of the methods or functions described herein. When executed by the processor 1802, these instructions (e.g., instruction 1808) cause various operations to implement the disclosed examples.

[0156] Instructions 1808 can be sent or received over the network 1820 via a network interface device (e.g., the network interface component included in the communication component 1836), using a transmission medium and using any one of a plurality of well-known transmission protocols (e.g., Hypertext Transfer Protocol (HTTP)). Similarly, instructions 1808 can be sent or received using a transmission medium via a coupling (e.g., a peer-to-peer coupling) to the device 1822.

[0157] Software architecture

[0158] Figure 19FIG. 1900 is a block diagram showing a software architecture 1904 that can be installed on any one or more of the devices described herein. The software architecture 1904 is supported by hardware such as a machine 1902 that includes a processor 1920, a memory 1926, and I / O components 1938. In this example, the software architecture 1904 can be conceptualized as a stack of layers, where each layer provides a specific function. The software architecture 1904 includes layers such as an operating system 1912, libraries 1910, frameworks 1908, and applications 1906. In operation, the application 1906 activates API calls 1950 through the software stack and receives messages 1952 in response to the API calls 1950.

[0159] The operating system 1912 manages hardware resources and provides common services. The operating system 1912 includes, for example, a kernel 1914, services 1916, and drivers 1922. The kernel 1914 acts as an abstraction layer between the hardware layer and other software layers. For example, the kernel 1914 provides memory management, processor management (e.g., scheduling), component management, networking, and security settings, among other functions. The services 1916 can provide other common services to other software layers. The drivers 1922 are responsible for controlling or interfacing with the underlying hardware. For example, the drivers 1922 can include a display driver, a camera device driver, or a low-power driver, a flash driver, a serial communication driver (e.g., a USB driver), a WI- driver, an audio driver, a power management driver, and the like.

[0160] The libraries 1910 provide common low-level infrastructure used by the applications 1906. The libraries 1910 can include system libraries 1918 (e.g., the C standard library), which provide functions such as memory allocation functions, string manipulation functions, mathematical functions, and the like. In addition, the libraries 1910 can include API libraries 1924, such as media libraries (e.g., libraries for supporting the rendering and manipulation of various media formats, such as Moving Picture Experts Group 4 (MPEG4), Advanced Video Coding (H.264 or AVC), Moving Picture Experts Group Layer 3 (MP3), Advanced Audio Coding (AAC), Adaptive Multi-Rate (AMR) audio codec, Joint Photographic Experts Group (JPEG or JPG), or Portable Network Graphics (PNG)), graphics libraries (e.g., the OpenGL framework for rendering graphical content in two-dimensional (2D) and three-dimensional (3D) on a display), database libraries (e.g., SQLite, which provides various relational database functions), web libraries (e.g., WebKit, which provides web browsing functions), and the like. The libraries 1910 can also include various other libraries 1928 to provide many other APIs to the applications 1906.

[0161] The framework 1908 provides a common advanced infrastructure for use by the application 1906. For example, the framework 1908 provides various graphical user interface (GUI) functions, advanced resource management, and advanced location services. The framework 1908 may provide a wide range of other APIs that can be used by the application 1906, some of which may be specific to a particular operating system or platform.

[0162] In an example, the application 1906 may include a home application 1936, a contacts application 1930, a browser application 1932, a book reader application 1934, a location application 1942, a media application 1944, a messaging application 1946, a gaming application 1948, and various other applications such as a third-party application 1940. The application 1906 is a program that executes functions defined in the program. One or more of the applications 1906 can be created using various programming languages, such as object-oriented programming languages (e.g., Objective-C, Java, or C++) or procedural programming languages (e.g., C language or assembly language). In a particular example, the third-party application 1940 (e.g., an application developed using an ANDROID TM or IOS TM software development kit (SDK)) can be mobile software that runs on a mobile operating system such as IOS TM , ANDROID TM , , Phone or another mobile operating system. In this example, the third-party application 1940 can activate an API call 1950 provided by the operating system 1912 to facilitate the functions described herein.

[0163] Processing component

[0164] Now turning to Figure 20 , a graphical representation of a processing environment 2000 is shown, which includes processors 2002, 2006, and 2008 (e.g., a GPU, a CPU, or a combination thereof).

[0165] The processor 2002 is shown coupled to a power supply 2004 and includes (permanently configured or temporarily instantiated) modules, namely, a collection management component 2010, an enhancement component 2012, and a transient timer component 2014. The collection management component 2010 operably generates and manages a private collection of media content items, the enhancement component 2012 operably generates an invitation media overlay, and the transient timer component 2014 operably manages an access time associated with each media content item in the private collection. As shown, the processor 2002 is communicatively coupled to both the processor 2006 and the processor 2008.

[0166] Glossary

[0167] "Carrier signal" means any non - tangible medium capable of storing, encoding, or carrying instructions executed by a machine and includes digital or analog communication signals or other non - tangible media to facilitate the communication of such instructions. Instructions can be sent or received over a network via a network interface device using a transmission medium.

[0168] "Client device" means any machine that interfaces with a communication network to obtain resources from one or more server systems or other client devices. A client device can be, but is not limited to, a mobile phone, desktop computer, laptop computer, portable digital assistant (PDA), smartphone, tablet computer, ultrabook, netbook, laptop computer, multi - processor system, microprocessor - based or programmable consumer electronics, game console, set - top box, or any other communication device that a user can use to access a network.

[0169] "Communication network" means one or more portions of a network, which can be an ad - hoc network, intranet, extranet, virtual private network (VPN), local area network (LAN), wireless LAN (WLAN), wide area network (WAN), wireless WAN (WWAN), metropolitan area network (MAN), the Internet, a portion of the Internet, a portion of the public switched telephone network (PSTN), plain old telephone service (POTS) network, cellular telephone network, wireless network, Wi - Fi network, another type of network, or a combination of two or more such networks. For example, a network or a portion of a network can include a wireless network or a cellular network, and the coupling can be a code - division multiple access (CDMA) connection, global system for mobile communications (GSM) connection, or other type of cellular or wireless coupling. In this example, the coupling can implement any data - transfer technology among various types of data - transfer technologies, such as single - carrier radio transmission technology (1xRTT), evolution - data optimized (EVDO) technology, general packet radio service (GPRS) technology, GSM - enhanced data rates for GSM evolution (EDGE) technology, 3rd Generation Partnership Project (3GPP) including 3G, 4th - generation wireless (4G) network, universal mobile telecommunications system (UMTS), high - speed packet access (HSPA), worldwide interoperability for microwave access (WiMAX), long - term evolution (LTE) standard, other data - transfer technologies defined by various standards - setting organizations, other long - distance protocols, or other data - transfer technologies.

[0170] "Component" refers to a device, physical entity, or logic having the following boundaries: the boundaries are defined by functions or subroutine calls, branch points, APIs, or other techniques provided for partitioning or modularizing a particular processing or control function. Components can be combined with other components via their interfaces to perform machine processes. A component can be an encapsulated functional hardware unit designed to be used with other components and can be part of a program that generally performs a specific function among related functions. Components can constitute software components (e.g., code implemented on a machine-readable medium) or hardware components. A "hardware component" is a tangible unit capable of performing certain operations and can be configured or arranged in some physical manner. In various example embodiments, one or more computer systems (e.g., a stand-alone computer system, a client computer system, or a server computer system) or one or more hardware components of a computer system (e.g., a processor or a group of processors) can be configured by software (e.g., an application or a part of an application) to operate to perform certain operations as described herein as a hardware component. A hardware component can also be implemented mechanically, electronically, or in any suitable combination thereof. For example, a hardware component can include dedicated circuitry or logic permanently configured to perform certain operations. A hardware component can be a dedicated processor, such as a field programmable gate array (FPGA) or an application specific integrated circuit (ASIC). A hardware component can also include programmable logic or circuitry temporarily configured by software to perform certain operations. For example, a hardware component can include software executed by a general purpose processor or other programmable processor. Once configured by such software, the hardware component becomes a particular machine (or a particular component of a machine) uniquely customized to perform the configured function and is no longer a general purpose processor. It will be understood that the decision to implement a hardware component mechanically, in dedicated and permanently configured circuitry, or in temporarily configured circuitry (e.g., configured by software) can be driven by cost and time considerations. Accordingly, the phrase "hardware component" (or "hardware-implemented component") should be understood to include a tangible entity, i.e., an entity that is physically constructed, permanently configured (e.g., hard-wired), or temporarily configured (e.g., programmed) to operate in some manner or perform certain operations described herein. Considering embodiments where a hardware component is temporarily configured (e.g., programmed), each of the hardware components need not be configured or instantiated at any given time. For example, in the case where a hardware component includes a general purpose processor configured by software to become a dedicated processor, the general purpose processor can be configured into different dedicated processors (e.g., including different hardware components) at different times. Thus, software configures one or more specific processors to, for example, constitute a particular hardware component at one time and different hardware components at different times. Hardware components can provide information to and receive information from other hardware components. Thus, the described hardware components can be considered communicatively coupled.In the presence of multiple hardware components, communication can be achieved by transmitting signals between or among two or more hardware components (e.g., via appropriate circuitry and buses). In embodiments where multiple hardware components are configured or instantiated at different times, communication between such hardware components can be achieved, for example, by storing information in a memory structure accessible to the multiple hardware components and retrieving the information from the memory structure. For example, one hardware component can perform an operation and store the output of the operation in a memory device communicatively coupled thereto. Then, other hardware components can access the memory device at a subsequent time to retrieve the stored output and process it. Hardware components can also initiate communication with input or output devices and can operate on resources (e.g., collection of information). Various operations of the example methods described herein can be performed at least in part by one or more processors that are temporarily configured (e.g., via software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such processors can constitute processor-implemented components that operate to perform one or more of the operations or functions described herein. As used herein, a "processor-implemented component" refers to a hardware component implemented using one or more processors. Similarly, the methods described herein can be implemented at least in part by a processor, where a particular one or more processors are examples of hardware. For example, at least some operations of the method can be performed by one or more processors 1004 or processor-implemented components. Additionally, one or more processors can also operate to support the execution of relevant operations in a "cloud computing" environment or as a "software as a service" (SaaS) operation. For example, at least some of the operations can be performed by a group of computers (as an example of a machine including processors), where the operations are accessible via a network (e.g., the Internet) and via one or more appropriate interfaces (e.g., an API). Execution of certain operations can be distributed among processors, which can reside not only within a single machine but also be deployed across several machines. In some example embodiments, the processor or processor-implemented components can be located in a single geographical location (e.g., within a home environment, an office environment, or a server farm). In other example embodiments, the processor or processor-implemented components can be distributed across several geographical locations.

[0171] "Computer-readable storage medium" refers to both machine storage media and transmission media. Thus, the term includes both storage devices / media and carrier / modulated data signals. The terms "machine-readable medium", "computer-readable medium", and "device-readable medium" mean the same thing and can be used interchangeably in this disclosure.

[0172] "Ephemeral message" refers to a message that is accessible for a limited duration. Ephemeral messages can be text, images, videos, etc. The access time of an ephemeral message can be set by the message sender. Alternatively, the access time can be a default setting or a setting specified by the recipient. Regardless of the setting technique, the message is temporary.

[0173] "Machine storage medium" refers to a single or multiple storage devices and media (e.g., centralized or distributed databases, and associated caches and servers) that store executable instructions, routines, and data. Thus, the term should be considered to include, but not be limited to, solid-state memories as well as optical and magnetic media, including memories internal or external to a processor. Specific examples of machine storage media, computer storage media, and device storage media include: non-volatile memories, including, for example, semiconductor memory devices such as erasable programmable read-only memories (EPROMs), electrically erasable programmable read-only memories (EEPROMs), FPGAs, and flash memory devices; magnetic disks, such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks. The terms "machine storage medium", "device storage medium", and "computer storage medium" mean the same thing and can be used interchangeably in this disclosure. The terms "machine storage medium", "computer storage medium", and "device storage medium" expressly exclude carrier waves, modulated data signals, and other such media, at least some of which are subsumed in the term "signal medium".

[0174] "Non-transitory computer-readable storage medium" refers to a tangible medium that can store, encode, or carry instructions executable by a machine.

[0175] "Signal medium" refers to any intangible medium that can store, encode, or carry instructions executable by a machine, and "signal medium" includes digital or analog communication signals or other intangible media for facilitating the transmission of software or data. The term "signal medium" should be considered to include any form of modulated data signal, carrier wave, etc. The term "modulated data signal" refers to a signal whose one or more characteristics are set or changed in such a way that information is encoded in the signal. The terms "transmission medium" and "signal medium" mean the same thing and can be used interchangeably in this disclosure.
