[0019] The following description includes systems, methods, techniques, instruction sequences and computing machine program products that embody the illustrative embodiments of the present disclosure. In the following description, for the purpose of illustration, many specific details are set forth to provide an understanding of the various embodiments of the subject of the present invention. However, it will be apparent to those skilled in the art that the embodiments of the subject of the present invention can be practiced without these specific details. Typically, known instruction instances, protocols, structures and techniques are not necessarily shown in detail.

[0020] Operators of social networking systems sometimes offer their applications on many different platforms. For example, a social networking application can be used on a smartphone and on a personal computer. When a new platform is added to the mix of platforms, it may take some time before users become aware of the new platform and adopt the new platform. Therefore, it may be desirable to introduce the new platform into the mix of platforms in a subtle and natural way. One way to do this is to indicate that other users associated with the user in the social network are using the new platform when the user uses a specified platform to access the services of the social networking system by using a presence icon associated with the user.

[0021] In some examples, a user uses a user device to access an interactive service to participate in a chat session. Sometimes, a chat session is a one-to-one session in which a user chats with one other user. The user device provides a presence icon associated with other users, and the presence icon indicates whether the user is using a specified platform. If the other user is using the specified platform, the user device provides a presence icon associated with the user, and the presence icon includes a portion indicating the use of the specified platform by the other user. In addition, the user device provides a status message that identifies the user as using the specified platform. The user device also provides a selectable educational action button, which, when selected by the user, causes the user device to provide an educational user interface to the user.

[0022] Other technical features may be apparent to those skilled in the art from the following drawings, descriptions and claims.

[0023] Networked computing environment

[0024] Figure 1 1 is a block diagram illustrating an example interactive system 100 for facilitating interactions over a network (e.g., exchanging text messages, conducting text audio and video calls, or playing games). The interactive system 100 includes multiple client systems 102, each of which hosts multiple applications including an interactive client 104 and other applications 106. Each interactive client 104 is communicatively coupled to other instances of the interactive client 104 (e.g., hosted on respective other user systems 102), an interactive server system 110, and third-party servers 112 via one or more communication networks including a network 108 (e.g., the Internet). The interactive client 104 can also communicate with the locally hosted application 106 using an application program interface (API).

[0025] Each user system 102 may include a plurality of user devices, such as a mobile device 114, a head wearable device 116, and a computer user device 118, which may be communicatively coupled to exchange data and messages.

[0026] The interactive clients 104 interact with other interactive clients 104 and with the interactive server system 110 via the network 108. The data exchanged between the interactive clients 104 (e.g., interaction 120) and between the interactive clients 104 and the interactive server system 110 includes functions (e.g., commands for activating functions) and payload data (e.g., text, audio, video or other multimedia data).

[0027] The interactive server system 110 provides server-side functions to the interactive clients 104 via the network 108. Although certain functions of the interactive system 100 are described herein as being performed by the interactive clients 104 or by the interactive server system 110, whether certain functions are located within the interactive clients 104 or within the interactive server system 110 may be a design choice. For example, it may be technically preferred to initially deploy certain technologies and functions within the interactive server system 110, but to later migrate the technologies and functions to the interactive clients 104 where the user system 102 has sufficient processing power.

[0028] The interactive server system 110 supports various services and operations provided to the interactive clients 104. Such operations include sending data to the interactive clients 104, receiving data from the interactive clients 104, and processing data generated by the interactive clients 104. The data may include message content, user device information, geolocation information, media enhancements and overlays, message content persistence conditions, social network information, and live event information. The data exchange within the interactive system 100 is activated and controlled by functions available through the user interface (UI) of the interactive client 104.

[0029] Turning now specifically to the interaction server system 110, an application program interface (API) server 122 is coupled to and provides a programming interface to the interaction server 124, making the functionality of the interaction server 124 accessible to the interaction clients 104, other applications 106, and third-party servers 112. The interaction server 124 is communicatively coupled to a database server 126, thereby facilitating access to a database 128 that stores data associated with interactions processed by the interaction server 124. Similarly, a web server 130 is coupled to the interaction server 124 and provides a web-based interface to the interaction server 124. To this end, the web server 130 handles incoming network requests via the Hypertext Transfer Protocol (HTTP) and several other related protocols.

[0030] The application program interface (API) server 122 receives and sends interaction data (e.g., commands and message payloads) between the interaction server 124 and the client system 102 (and, for example, the interaction client 104 and other applications 106) and the third-party server 112. Specifically, the application program interface (API) server 122 provides a set of interfaces (e.g., routines and protocols) that the interaction client 104 and other applications 106 can call or query to activate the functions of the interaction server 124. The application program interface (API) server 122 exposes various functions supported by the interaction server 124, including account registration; login functionality; sending interaction data from a particular interaction client 104 to another interaction client 104 via the interaction server 124; transferring media files (e.g., images or videos) from the interaction client 104 to the interaction server 124; setting up a collection of media data (e.g., a story); retrieving a friend list of a user of the user system 102; retrieving messages and content; adding and removing entities (e.g., friends) from an entity graph (e.g., a social graph); locating friends in a social graph; and opening application events (e.g., related to an interaction client 104).

[0031] The interactive server 124 hosts multiple systems and subsystems, as shown below. Figure 2 describe.

[0032] System Architecture

[0033] Figure 2 1 is a block diagram showing additional details about the interactive system 100 according to some examples. Specifically, the interactive system 100 is shown to include an interactive client 104 and an interactive server 124. The interactive system 100 includes a number of subsystems that are supported on the client side by the interactive client 104 and on the server side by the interactive server 124. Example subsystems are discussed below.

[0034] Image processing system 202 provides various functions that enable a user to capture and enhance (eg, annotate or otherwise modify or edit) media content associated with a message.

[0035] The camera system 204 includes control software (e.g., in a camera application) that interacts with and controls the hardware camera hardware of the user system 102 (e.g., directly or via operating system control) to modify and enhance real-time images captured and displayed via the interactive client 104.

[0036] The enhancement system 206 provides functionality related to the generation and publication of enhancements (e.g., media overlays) to images captured in real time by the camera of the user system 102 or retrieved from the memory of the user system 102. For example, the enhancement system 206 is operable to select, present, and display media overlays (e.g., image filters or image lenses) to the interactive client 104 for enhancing real-time images received via the camera system 204 or stored images retrieved from the memory of the user system 102. These enhancements are selected and presented to the user of the interactive client 104 by the enhancement system 206 based on some input and data, such as:

[0037] The geolocation of the user system 102; and

[0038] Social network information of users of the user system 102 .

[0039] Enhancement can 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. Audio and visual content or visual effects can be applied to media content items (e.g., photos or videos) at user systems 102 for transmission in messages, or applied to video content such as video content streams or feeds sent from interactive clients 104. Therefore, image processing system 202 can interact with various subsystems of communication system 210, and supports various subsystems of communication system 208, such as messaging system 210 and video communication system 212.

[0040] Media overlays may include text or image data that can be superimposed on a photo taken by the user system 102 or a video stream produced by the user system 102. In some examples, the media overlay may be a location overlay (e.g., Venice Beach), the name of a live event, or a business name overlay (e.g., Beach Cafe). In other examples, the image processing system 202 uses the geolocation of the user system 102 to identify a media overlay that includes the name of a business at the geolocation of the user system 102. The media overlay may include other tags associated with the business. The media overlay may be stored in the database 128 and accessed by the database server 126.

[0041] The image processing system 202 provides a user-based publishing platform that enables a user to select a geographic location on a map and upload content associated with the selected geographic location. The user can also specify situations in which a particular media overlay should be provided to other users. The image processing system 202 generates a media overlay that includes the uploaded content and associates the uploaded content with the selected geographic location.

[0042] The augmented creation system 214 supports the augmented reality developer platform and includes applications for content creators (e.g., artists and developers) to create and publish augmentations (e.g., augmented reality experiences) for the interactive clients 104. The augmented creation system 214 provides content creators with a library of built-in features and tools, including, for example, custom shaders, tracking techniques, and templates.

[0043] In some examples, the enhancement creation system 214 provides a merchant-based publishing platform that enables merchants to select specific enhancements associated with a geographic location via a bidding process. For example, the enhancement creation system 214 associates the media overlay of the highest bidding merchant with the corresponding geographic location for a predefined amount of time.

[0044] The communication system 208 is responsible for enabling and processing various forms of communication and interaction within the interactive system 100, and includes a messaging system 210, an audio communication system 216, and a video communication system 212. The messaging system 210 is responsible for enforcing temporary or time-limited access to content by the interactive clients 104. The messaging system 210 includes multiple timers (e.g., in a transient timer system 218) that selectively enable access (e.g., for presentation and display) of messages and associated content via the interactive clients 104 based on 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 218 are provided below. The audio communication system 216 enables and supports audio communication (e.g., real-time audio chat) between multiple interactive clients 104. Similarly, the video communication system 212 enables and supports video communication (e.g., real-time video chat) between multiple interactive clients 104.

[0045] The user management system 220 is operationally responsible for managing user data and profiles, and includes a social networking system 222 that maintains information about relationships between users of the interactive system 100 .

[0046] The collection management system 224 is operationally responsible for managing a collection or collection of media (e.g., a collection of text, image video, and audio data). A collection of content (e.g., messages, including images, videos, text, and audio) can be organized into an "event library" or "event story". Such a collection can be made available within a specified time period (e.g., the duration of the event to which the content relates). For example, content related to a concert can be available as a "story" for the duration of the concert. The collection management system 224 can also be responsible for publishing an icon that provides a notification of a specific collection to the user interface of the interactive client 104. The collection management system 224 includes a curation function that enables collection managers to manage and curate specific content collections. For example, a curation interface enables event organizers to curate a collection of content related to a specific event (e.g., deleting inappropriate content or redundant messages). In addition, the collection management system 224 uses machine vision (or image recognition technology) and content rules to automatically curate content collections. In some examples, compensation can be paid to users for including user-generated content in a collection. In such a case, the collection management system 224 operates to automatically pay such users to use their content.

[0047] The mapping system 226 provides various geolocation functions and supports the presentation of map-based media content and messages by the interactive client 104. For example, the mapping system 226 enables the display of a user icon or avatar (e.g., stored in the profile data 302) on a map to indicate the current or past locations of the user's "friends" within the context of the map, as well as media content (e.g., a collection of messages including photos and videos) generated by these friends. For example, on the map interface of the interactive client 104, a message posted by the user to the interactive system 100 from a particular geolocation can be displayed to the "friends" of a particular user within the context of that particular location on the map. The user can also share his or her location and status information with other users of the interactive system 100 via the interactive client 104 (e.g., using an appropriate status avatar), where the location and status information is similarly displayed to the selected user within the context of the map interface of the interactive client 104.

[0048] The gaming system 228 provides various gaming functions within the context of the interactive client 104. The interactive client 104 provides a gaming interface that provides a list of available games that can be launched by a user within the context of the interactive client 104 and played with other users of the interactive system 100. The interactive system 100 also enables a particular user to invite other users to participate in playing a particular game by sending an invitation to such other users from the interactive client 104. The interactive client 104 also supports voice, video, and text messaging (e.g., chat) within the context of game play, provides leaderboards for games, and also supports the provision of in-game rewards (e.g., game coins and items).

[0049] The external resource system 230 provides an interface for the interactive client 104 to communicate with a remote server (e.g., a third-party server 112) to launch or access an external resource (i.e., an application or applet). Each third-party server 112 hosts, for example, an application or a small-scale version of an application based on a markup language (e.g., HTML5) (e.g., a game application, a utility application, a payment application, or a ride-sharing application). The interactive client 104 can launch a web-based resource (e.g., an application) by accessing an HTML5 file from a third-party server 112 associated with a web-based resource. The application hosted by the third-party server 112 is programmed in JavaScript using a software development kit (SDK) provided by the interactive server 124. The SDK includes an application program interface (API) with functions that can be called or activated by a web-based application. The interactive server 124 hosts a JavasScript library that provides a given external resource access to specific user data of the interactive client 104. HTML5 is an example of a technology for programming games, but applications and resources programmed based on other technologies can be used.

[0050] In order to integrate the functionality of the SDK into the web-based resource, the SDK is downloaded from the interactive server 124 by the third-party server 112, or the SDK is received by the third-party server 112 in other ways. Once downloaded or received, the SDK is included as part of the application code of the web-based external resource. The code of the web-based resource can then call or activate certain functions of the SDK to integrate the features of the interactive client 104 into the web-based resource.

[0051] The SDK stored on the interactive server system 110 effectively provides a bridge between external resources (e.g., applications 106 or applets) and the interactive client 104. This gives the user a seamless experience of communicating with other users on the interactive client 104 while also preserving the appearance of the interactive client 104. In order to bridge the communication between the external resources and the interactive client 104, the SDK facilitates the communication between the third-party server 112 and the interactive client 104. The WebViewJavaScriptBridge running on the user system 102 establishes two one-way communication channels between the external resources and the interactive client 104. Messages are sent asynchronously between the external resources and the interactive client 104 via these communication channels. Each SDK function activation is sent as a message and a callback. Each SDK function is implemented by constructing a unique callback identifier and sending a message with the callback identifier.

[0052] By using the SDK, not all information from the interactive client 104 is shared with the third-party server 112. The SDK limits which information is shared based on the needs of the external resource. Each third-party server 112 provides an HTML5 file corresponding to a web-based external resource to the interactive server 124. The interactive server 124 can add a visual representation (e.g., a box design or other graphics) of the web-based external resource in the interactive client 104. Once the user selects the visual representation or instructs the interactive client 104 to access the features of the web-based external resource through the GUI of the interactive client 104, the interactive client 104 obtains the HTML5 file and instantiates the resource for accessing the features of the web-based external resource.

[0053] The interactive client 104 presents a graphical user interface (e.g., a login page or title screen) for an external resource. During, before, or after presenting the login page or title screen, the interactive client 104 determines whether the launched external resource has been previously authorized to access the user data of the interactive client 104. In response to determining that the launched external resource has been previously authorized to access the user data of the interactive client 104, the interactive client 104 presents another graphical user interface of the external resource including the functions and features of the external resource. In response to determining that the launched external resource has not been previously authorized to access the user data of the interactive client 104, after displaying the login page or title screen of the external resource for a threshold period of time (e.g., 3 seconds), the interactive client 104 slides up a menu (e.g., animating the menu to emerge from the bottom of the screen to the middle or other part of the screen) for authorizing the external resource to access the user data. The menu identifies the type of user data that the external resource will be authorized to use. In response to receiving a user selection of the accept option, the interactive client 104 adds the external resource to the list of authorized external resources and allows the external resource to access the user data from the interactive client 104. External resources are authorized by the interactive client 104 to access user data under the OAuth 2 framework.

[0054] The interaction client 104 controls the type of user data shared with the external resource based on the type of external resource that is authorized. For example, an external resource including a full-scale application (e.g., application 106) is provided with access to a first type of user data (e.g., a two-dimensional avatar of a user with or without different avatar characteristics). As another example, an external resource including a small-scale version of an application (e.g., a web-based version of the application) is provided with access to a second type of user data (e.g., payment information, a two-dimensional avatar of a user, a three-dimensional avatar of a user, and an avatar with various avatar characteristics). Avatar characteristics include different ways to customize the appearance of an avatar (e.g., different poses, facial features, clothing, etc.).

[0055] The advertising system 232 operatively enables third parties to purchase advertisements for presentation to end users via the interactive clients 104 and also handles the delivery and presentation of these advertisements.

[0056] Data Architecture

[0057] Figure 3 is a diagram illustrating a data structure 300 that may be stored in a database 304 of an interactive server system 110 according to some examples. Although the contents of the database 304 are illustrated as including a plurality of tables, it should be understood that data may be stored in other types of data structures (e.g., object-oriented databases).

[0058] Database 304 includes message data stored in message table 306. For any particular message, the message data includes at least message sender data, message recipient (or receiver) data, and payload. Figure 3 Additional details regarding information that may be included in a message and included within the message data stored in message table 306 are described.

[0059] The entity table 308 stores entity data and is linked (e.g., referenced) to the entity graph 310 and the profile data 302. The entity for which records are maintained within the entity table 308 may include a person, a corporate entity, an organization, an object, a place, an event, etc. Regardless of the entity type, any entity about which the interactive server system 110 stores data may be an identified entity. Each entity is provided with a unique identifier and an entity type identifier (not shown).

[0060] The entity graph 310 stores information about relationships and associations between entities. For example, such relationships may be simply social relationships based on interests or based on activities, professional relationships (e.g., working in a common company or organization). Some relationships between entities may be one-way, such as a personal user's subscription to a business or publishing user's digital content (e.g., a newspaper or other digital media outlet or brand). Other relationships may be two-way, such as a "friend" relationship between various users of the interactive system 100.

[0061] Certain permissions and relationships can be attached to each relationship, and can also be attached to each direction of the relationship. For example, a two-way relationship (e.g., a friend relationship between individual users) can include authorization for the publication of digital content items between the individual users, but certain restrictions or filters (e.g., based on content characteristics, location data, or time of day data) can be imposed on the publication of such digital content items. Similarly, a subscription relationship between an individual user and a business user can impose varying degrees of restrictions on the publication of digital content from the business user to the individual user, and can significantly limit or prevent the publication of digital content from the individual user to the business user. As an example of an entity, a particular user can record certain restrictions (e.g., by way of privacy settings) in the record of the entity within the entity table 308. Such privacy settings can apply to all types of relationships within the context of the interactive system 100, or can be selectively applied to only certain types of relationships.

[0062] The profile data 302 stores multiple types of profile data about a particular entity. Based on the privacy settings specified by the particular entity, the profile data 302 can be selectively used and presented to other users of the interactive system 100. In the case where the entity is a person, the profile data 302 includes, for example, the user name, phone number, address, settings (e.g., notification and privacy settings), and an avatar representation (or a collection of such avatar representations) selected by the user. The particular user can then selectively include one or more of these avatar representations within the content of messages transmitted via the interactive system 100 and on a map interface displayed to other users by the interactive client 104. The collection of avatar representations can include a "status avatar" that presents a graphical representation of a status or activity that the user can choose to transmit at a particular time.

[0063] Where the entity is a group, profile data 302 for the group may similarly include one or more avatar representations associated with the group, in addition to the group name, members, and various settings for the relevant group (eg, notifications).

[0064] Database 304 also stores enhancement data, such as overlays or filters, in enhancement table 312. Enhancement data is associated with and applied to videos (data for videos is stored in video table 314) and images (data for images is stored in image table 316).

[0065] In some examples, the filter is displayed as an overlay on an image or video during presentation to the recipient user. The filter can be of various types, including a user-selected filter from a set of filters presented to the sending user by the interactive client 104 when the sending user is composing a message. Other types of filters include geolocation filters (also referred to as geofilters), which can be presented to the sending user based on geolocation. For example, a geolocation filter specific to a nearby or special location can be presented by the interactive client 104 within the user interface based on geolocation information determined by a global positioning system (GPS) unit of the user system 102.

[0066] Another type of filter is a data filter, which can be selectively presented to the sending user by the interaction client 104 based on other input or information collected during the message creation process by the user system 102. Examples of data filters include the current temperature at a particular location, the current speed at which the sending user is traveling, the battery life of the user system 102, or the current time.

[0067] Other augmented data that may be stored in the image table 316 include augmented reality content items (eg, corresponding to application "lenses" or augmented reality experiences). Augmented reality content items may be real-time special effects and sounds that may be added to an image or video.

[0068] As described above, augmented data includes augmented reality (AR) content items, virtual reality (VR) content items, and mixed reality (MR) content items, overlays, image transformations, images, and modifications that can be applied to image data (e.g., videos or images). This includes real-time modifications that modify images when they are captured using the device sensors (e.g., one or more cameras) of the user system 102 and then display the modified images on the screen of the user system 102. This also includes modifications to stored content (such as video clips in a collection or group that can be modified). For example, in a user system 102 that can access 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 will modify the stored clips. Similarly, real-time video capture can use modifications to show how the video image currently captured by the sensor of the user system 102 will modify the captured data. Such data can be displayed only on the screen without being stored in the memory, or the content captured by the device sensor can be recorded and stored in the memory with or without modification (or both). In some systems, the preview feature can simultaneously show how different augmented reality content items will look in different windows in the display. For example, this can enable multiple windows with different pseudo-random animations to be viewed on the display at the same time.

[0069] Thus, data and various systems using augmented reality content items or other such transformation systems that use the data to modify content may involve detection of objects (e.g., faces, hands, bodies, cats, dogs, surfaces, objects, etc.) in video frames; tracking of such objects as they leave, enter, and move around the field of view; and modification or transformation of such objects as they are tracked. In various examples, different methods for implementing such transformations may be used. Some examples may involve: generating a three-dimensional mesh model of one or more objects; and using transformations and animated textures of the models within the video to implement the transformations. In some examples, tracking of points on the objects may be used to place images or textures (which may be two-dimensional or three-dimensional) at the tracked locations. In other examples, neural network analysis of the video frames may be used to place images, models, or textures in content (e.g., images or video frames). Thus, augmented reality content items involve both: images, models, and textures used to create transformations in the content; and additional modeling and analysis information required to implement such transformations using object detection, tracking, and placement.

[0070] Real-time video processing can be performed using any type of video data (e.g., video streams, video files, etc.) stored in the memory of any type of computerized system. For example, a user can load a video file and save it in the memory of the device, or a sensor of the device can be used to generate a video stream. In addition, computer animation models can be used to process any object, such as a human face and parts of a human body, an animal, or a non-living thing such as a chair, a car, or other objects.

[0071] In some examples, when a specific modification is selected together with the content to be transformed, the element to be transformed is identified by a computing device, and then if the element to be transformed is present in a frame of the video, it 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 types of transformations, the transformation of the frame of the video stream can be performed by different methods. For example, for the transformation of the frame that mainly refers to changing the form of the elements of the object, the characteristic points of each element of the object are calculated (for example, using an active shape model (ASM) or other known methods). Then, a grid based on the characteristic points is generated for each element of the object. The grid is used in a subsequent stage in which the elements of the object in the video stream are tracked. During the tracking process, the grid for each element is aligned with the location of each element. Then, additional points are generated on the grid.

[0072] In some examples, the transformation of some areas of the object using the elements of the object can be performed by calculating the characteristic points of each element of the object and generating a grid based on the calculated characteristic points. Points are generated on the grid, and then various areas based on these points are generated. Then, the elements of the object are tracked by aligning the area of ​​each element with the positioning of each element of at least one element, and the properties of the area can be modified based on the request for modification, thereby transforming the frame of the video stream. Depending on the specific request for modification, the properties of the mentioned area can be transformed in different ways. Such modifications may involve: changing the color of the area; removing at least part of the area from the frame of the video stream; including new objects in the area based on the modification request; and modifying or distorting the elements of the area or object. In various examples, any combination of such modifications or other similar modifications may be used. For certain models to be animated, some characteristic points can be selected as control points of the entire state space to be used to determine options for model animation.

[0073] In some examples of computer animation models for transforming image data using face detection, faces are detected on an image using a specific face detection algorithm (e.g., Viola-Jones). An active shape model (ASM) algorithm is then applied to the face region of the image to detect facial feature reference points.

[0074] Other methods and algorithms suitable for face detection may be used. For example, in some examples, landmarks are used to locate features, and landmarks represent distinguishable points that are present in most of the images considered. For example, for facial landmarks, the location of the left pupil can be used. If the initial landmarks are not recognizable (for example, if the person is wearing an eye patch), secondary landmarks can be used. Such a landmark identification procedure 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 shape using a similarity transformation (allowing translation, scaling, and rotation) that minimizes the average Euclidean distance between the shape points. The average shape is the average of the aligned training shapes.

[0075] The transformation system can capture an image or video stream on a user device (e.g., user system 102) and perform complex image manipulations locally on the user system 102 while maintaining an appropriate user experience, computational time, and power consumption. Complex image manipulations can include size and shape changes, emotion transformations (e.g., changing a face from a frown to a smile), state transitions (e.g., aging a subject, reducing apparent age, changing gender), style transformations, application of graphical elements, and any other suitable image or video manipulations implemented by a convolutional neural network that has been configured to execute efficiently on the user system 102.

[0076] In some examples, a computer animation model for transforming image data may be used by a system in which a user may capture an image or video stream of the user (e.g., a selfie) using a user system 102 having a neural network operating as part of an interactive client 104 operating on the user system 102. The transformation system operating within the interactive client 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 may exist in association with an interface described herein. The modification icon includes changes as a basis for modifying the user's face within the image or video stream as part of the modification operation. Once the modification icon is selected, the transformation system initiates a process of transforming the user's image to reflect the selected modification icon (e.g., generating a smile on the user). Once the image or video stream is captured and the specified modification is selected, the modified image or video stream may be presented in a graphical user interface displayed on the user system 102. The transformation system may implement a complex convolutional neural network on a portion of the image or video stream to generate and apply the selected modification. That is, a user can capture an image or video stream, and once a modification icon is selected, the modified result can be presented to the user in real time or near real time. In addition, the modification can be persistent while the video stream is being captured and the selected modification icon remains toggled. Machine-taught neural networks can be used to implement such modifications.

[0077] The graphical user interface presenting the modifications performed by the transformation system can supply additional interactive options to the user. Such options can be based on an interface for initiating content capture and selection of a particular computer animation model (e.g., initiated from a content creator user interface). In various examples, the modification can persist after the initial selection of the modification icon. The user can turn the modification on or off by tapping or otherwise selecting a face modified by the transformation system, and store it for later viewing or browsing to other areas of the imaging application. In the case of multiple faces modified by the transformation system, the user can globally turn the modification on or off by tapping or selecting a single face modified and displayed within the graphical user interface. In some examples, a single face in a group of multiple faces can be individually modified by tapping or selecting a single face or a series of single faces displayed within the graphical user interface, or such modifications can be individually switched.

[0078] The story table 318 stores data about a collection of messages and associated images, video or audio data that are compiled into a collection (e.g., a story or gallery). The creation of a particular collection can be initiated by a particular user (e.g., each user for whom a record is maintained in the entity table 308). A user can create a "personal story" in the form of a collection of content that has been created and sent / broadcasted by the user. To this end, the user interface of the interactive client 104 may include a user-selectable icon to enable the sending user to add specific content to his or her personal story.

[0079] The collection may also constitute a "live story", which is a collection of content from multiple users created manually, automatically, or using a combination of manual and automatic techniques. For example, a "live story" may constitute a curated stream of user-submitted content from different locations and events. Users whose user devices have location services enabled and who are at a co-located event at a particular time may be presented with the option of contributing content to a particular live story, for example, via the user interface of the interactive client 104. Live stories may be identified to the user by the interactive client 104 based on his or her location. The end result is a "live story" told from a group perspective.

[0080] Another type of content collection is called a "location story" that enables users whose user system 102 is located within a specific geographic location (e.g., on a college or university campus) to contribute to a specific collection. In some examples, contributions to location stories may require secondary authentication to verify that the end user belongs to a specific organization or other entity (e.g., is a student on a university campus).

[0081] As mentioned above, video table 314 stores video data that, in some examples, is associated with messages for which records are maintained within message table 306. Similarly, image table 316 stores image data associated with messages whose message data is stored in entity table 308. Entity table 308 may associate various enhancements from enhancement table 312 with various images and videos stored in image table 316 and video table 314.

[0082] Data communication architecture

[0083] Figure 4 is a schematic diagram illustrating the structure of a message 400 according to some examples, the message 400 being generated by an interactive client 104 for transmission to another interactive client 104 via an interactive server 124. The content of a particular message 400 is used to populate a message table 306 stored in a database 304 accessible by the interactive server 124. Similarly, the content of the message 400 is stored in memory as "in-transit" or "in-flight" data of the user system 102 or the interactive server 124. The message 400 is shown to include the following example components:

[0084] Message identifier 402 : a unique identifier that identifies the message 400 .

[0085] Message text payload 434 : Text to be generated by the user via the user interface of the user system 102 and included in the message 400 .

[0086] Message image payload 404: Image data captured by the camera component of the user system 102 or retrieved from the memory component of the user system 102 and included in the message 400. The image data for a message 400 sent or received may be stored in an image table 406.

[0087] Message video payload 408: Video data captured by the camera component or retrieved from the memory component of the user system 102 and included in the message 400. The video data for the message 400 sent or received may be stored in a video table 410.

[0088] Message audio payload 412 : audio data captured by a microphone or retrieved from a memory component of the user system 102 and included in the message 400 .

[0089] Message enhancement data 414: Enhancement data (e.g., filters, stickers, or other annotations or enhancements) representing enhancements to be applied to the message image payload 404, message video payload 408, or message audio payload 412 of the message 400. The enhancement data for a sent or received message 400 may be stored in an enhancement table 416.

[0090] Message duration parameter 418: A parameter value indicating the amount of time in seconds that the content of a message (eg, message image payload 404, message video payload 408, message audio payload 412) is to be presented to or made accessible to a user via the interactive client 104.

[0091] Message geolocation parameters 420: Geolocation data (e.g., latitude and longitude coordinates) associated with the content payload of the message. Multiple message geolocation parameter 420 values ​​may be included in the payload, with each of these parameter values ​​being associated with a content item included in the content (e.g., a specific image within a message image payload 404 or a specific video in a message video payload 408).

[0092] Message story identifier 422: An identifier value that identifies one or more content collections (e.g., a "story" identified in story table 424) associated with a particular content item in message image payload 404 of message 400. For example, multiple images within message image payload 404 may each be associated with multiple content collections using an identifier value.

[0093] Message tags 426: Each message 400 may be tagged with a plurality of tags, each of which indicates the subject of the content included in the message payload. For example, where a particular image included in the message image payload 404 depicts an animal (e.g., a lion), a tag value may be included within the message tags 426 indicating the relevant animal. The tag value may be manually generated based on user input, or may be automatically generated using, for example, image recognition.

[0094] • Message sender identifier 428: An identifier (eg, a messaging system identifier, an email address, or a device identifier) ​​that indicates the user of the user system 102 on which the message 400 was generated and from which the message 400 was sent.

[0095] • Message recipient identifier 430: Indicates an identifier (eg, a messaging system identifier, an email address, or a device identifier) ​​of the user of user system 102 to which message 400 is addressed.

[0096] The content (e.g., value) of each component of message 400 may be a pointer to a location in a table where the content data value is stored. For example, the image value in message image payload 404 may be a pointer (or address) to a location within image table 406. Similarly, the value within message video payload 408 may point to data stored within video table 410, the value stored within message enhancement data 418 may point to data stored in enhancement table 416, the value stored within message story identifier 422 may point to data stored in story table 424, and the values ​​stored within message sender identifier 428 and message recipient identifier 430 may point to user records stored within entity table 432.

[0097] Time-based access restriction architecture

[0098] Figure 5 is a schematic diagram illustrating an access restriction process 500 according to which access to content (e.g., a multimedia payload of an ephemeral message 502 and associated data) or a collection of content (e.g., an ephemeral message group 504) can be time-restricted (e.g., ephemeral).

[0099] The ephemeral message 502 is shown to be associated with a message duration parameter 506, the value of which determines the amount of time that the ephemeral message 502 will be displayed by the interactive client 104 to the receiving user of the ephemeral message 502. In some examples, the receiving user may view the ephemeral message 502 for up to 10 seconds, depending on the amount of time specified by the sending user using the message duration parameter 506.

[0100] The message duration parameter 506 and the message recipient identifier 508 are shown as inputs to a message timer 510, which is responsible for determining the amount of time that the ephemeral message 502 is shown to the particular receiving user identified by the message recipient identifier 508. In particular, the ephemeral message 502 is shown to the associated receiving user for a period of time determined by the value of the message duration parameter 506. The message timer 510 is shown as providing an output to a more generalized messaging system 512, which is responsible for the overall timing of displaying content (e.g., the ephemeral message 502) to the receiving user.

[0101] exist Figure 51. The ephemeral message 502 is shown as being included in an ephemeral message group 504 (e.g., a collection of messages in a personal story or an event story). The ephemeral message group 504 has an associated group duration parameter 514, the value of which determines the duration for which the ephemeral message group 504 is presented and accessible to users of the interactive system 100. For example, the group duration parameter 514 may be the duration of a concert, wherein the ephemeral message group 504 is a collection of content related to the concert. Alternatively, a user (an owning user or a curator user) may specify the value of the group duration parameter 514 when performing setup and creation of the ephemeral message group 504.

[0102] In addition, each ephemeral message 502 within the ephemeral message group 504 has an associated group participation parameter 516, the value of which determines the duration for which the ephemeral message 502 will be accessible within the context of the ephemeral message group 504. Thus, a particular ephemeral message group 504 may "expire" and become inaccessible within the context of the ephemeral message group 504 before the ephemeral message group 504 itself expires according to the group duration parameter 514. The group duration parameter 514, the group participation parameter 516, and the message recipient identifier 508 each provide inputs to a group timer 518, which first operatively determines whether a particular ephemeral message 502 of the ephemeral message group 504 will be displayed to a particular receiving user, and if so, how long to display it. Note that the identity of the particular receiving user is also known to the ephemeral message group 504 due to the message recipient identifier 508.

[0103] Thus, the group timer 518 operatively controls the total lifespan of the associated ephemeral message group 504 and the individual ephemeral messages 502 included in the ephemeral message group 504. In some examples, each ephemeral message 502 within the ephemeral message group 504 remains viewable and accessible for a period of time specified by the group duration parameter 514. In another example, within the context of the ephemeral message group 504, a particular ephemeral message 502 may expire based on the group participation parameter 516. Note that even within the context of the ephemeral message group 504, the message duration parameter 506 may still determine the duration for which a particular ephemeral message 502 is displayed to a receiving user. Thus, the message duration parameter 506 determines the duration for which a particular ephemeral message 502 is displayed to a receiving user, regardless of whether the receiving user views the ephemeral message 502 within the context of the ephemeral message group 504 or outside the context of the ephemeral message group 504.

[0104] In addition, the messaging system 512 may be operative to remove a particular ephemeral message 502 from the ephemeral message group 504 based on a determination that the particular ephemeral message 502 has exceeded the associated group participation parameter 516. For example, when the sending user has established a group participation parameter 516 of 24 hours from posting, the messaging system 512 will remove the associated ephemeral message 502 from the ephemeral message group 504 after the specified 24 hours. The messaging system 512 is also operative to remove an ephemeral message group 504 when the group participation parameter 516 for each ephemeral message 502 within the ephemeral message group 504 has expired, or when the ephemeral message group 504 itself has expired according to the group duration parameter 514.

[0105] In some use cases, the creator of a particular ephemeral message group 504 may specify an indefinite group duration parameter 514. In this case, the expiration of the group participation parameter 516 of the last remaining ephemeral message 502 within the ephemeral message group 504 will determine when the ephemeral message group 504 itself expires. In this case, a new ephemeral message 502 with a new group participation parameter 516 added to the ephemeral message group 504 effectively extends the life of the ephemeral message group 504 to a value equal to the group participation parameter 516.

[0106] In response to the messaging system 512 determining that the ephemeral message group 504 has expired (e.g., is no longer accessible), the messaging system 512 communicates with the interactive system 100 (and, for example, in particular the interactive client 104) to cause the indicia (e.g., icon) associated with the relevant ephemeral message group 504 to no longer be displayed within the user interface of the interactive client 104. Similarly, when the messaging system 512 determines that the message duration parameter 506 of a particular ephemeral message 502 has expired, the messaging system 512 causes the interactive client 104 to no longer display the indicia (e.g., icon or text identification) associated with the ephemeral message 502.

[0107] According to some examples, Fig. 6A is a process flow chart of the platform notification method 600, and Figure 6B is a sequence diagram of the platform notification method 600, Figure 6C , Fig.6D , Fig. 6E and Fig. 6F6 is an illustration of a user interface of a platform notification method 600. A user device 626 (e.g., any of the user devices of the user system 102) uses the platform notification method 600 to provide a user with a notification that one or more other users in a chat session are using a particular platform to participate in the chat session. The user uses the user device 626 of the user system (e.g., the user system 102) to access one or more interaction servers 124 (e.g., interaction server 628) of the interaction system 100, thereby providing chat session services to the user.

[0108] In operation 602, the interaction server 628 receives chat session participation request data 630 from one or more other users using corresponding one or more other user devices 624. The chat session participation request data 630 includes a request to enter into a chat session and platform data indicating what platform the user is using to access the interaction server 628 and participate in the chat session. The interaction server 628 generates chat state message data 656 based on the chat session participation request data 630, and the chat state message data 656 includes user identifiers of other users in the chat session associated with platform identifiers, and the platform identifier indicates what platform each other user is using to access the interaction server 628 and participate in the chat session. The interaction server 628 transmits the chat state message data 656 to the user device 626.

[0109] In operation 604 , the interaction server 628 detects, based on the chat status message data 656 , that one or more other users are using the designated platform.

[0110] In operation 606 , the user device 626 determines whether the chat session is a group chat session in which two or more other users are in the chat session, or whether the chat session is a one-to-one chat session in which one other user is in the chat session.

[0111] In operation 608, based on determining that the chat session is a group chat session, the user device 626 provides a group chat session user interface 648 to the user. The group chat session user interface 648 includes a display portion for displaying user communications 634. The group chat session user interface 648 also includes two or more user presence icons 640 associated with other users, which indicate the presence of other users participating in the group chat. The user device 626 determines whether the other user is using a specified platform based on the chat status message data 656. Based on determining that the other user is using a specified platform, the user device 626 provides a platform presence icon 632 indicating that the other user is using a specified platform. Based on determining that the other user is not using a specified platform, the user device 626 provides a presence icon 658 about the other user without a platform indication. The group chat session user interface 648 also includes a specified platform notification 636 indicating that the other user is using a specified platform. The group chat session user interface 648 also includes a selectable educational action button 638, which the user selects to learn more about the specified platform.

[0112] In operation 610, based on determining that the chat session is a one-to-one chat session, the user device 626 provides a one-to-one chat session user interface 650 to the user. The one-to-one chat session user interface 650 includes a display portion for displaying user communications 634. The one-to-one chat session user interface 650 also includes a presence icon indicating the presence of other users participating in the one-to-one chat session. The user device 626 determines whether the other user is using the specified platform based on the chat status message data 656. Based on determining that the other user is using the specified platform, the user device 626 provides an alternative platform presence icon 642 indicating that the other user is using the specified platform. Based on determining that the other user is not using the specified platform, the user device 626 provides a simple presence icon about the other user without a special indication. The one-to-one chat session user interface 650 also includes a specified platform notification 636 indicating that the other user is using the specified platform. The one-to-one chat session user interface 650 also includes a selectable educational action button 638, which the user selects to learn more about the specified platform.

[0113] In operation 612 , the user device 626 detects that the user has selected the selectable educational action button 638 from the group chat session user interface 648 or the one-to-one chat session user interface 650 .

[0114] In operation 614, based on detecting that the user has selected the selectable educational action button 638, the user device 626 provides the user with a platform educational user interface 652. The platform educational user interface 652 includes a task bar 660 with an advertising display, which includes an informational or advertising display portion for displaying information about the specified platform. The task bar 660 with the advertising display also includes a link to other information button 644, which can be selected by the user to obtain a link to other information about the specified platform for the user. The task bar 660 with the advertising display also includes a send action button 662, which the user selects to terminate the platform notification method 600 and continue the chat session on the off-platform site.

[0115] In operation 616, the user device 626 detects the user's selection of the link to other information button 644 and copies a uniform resource link (URL) to the specified platform to the clipboard of the user device.

[0116] In operation 618, based on detecting the user's selection of the link to other information button 644, the user device 626 provides the user with a feedback message user interface 654. The feedback message user interface 654 includes a feedback message 646 indicating that the URL to the specified platform has been copied to the user device 626 clipboard data store.

[0117] In operation 620, the user device 626 detects a user selection of a send action button 662. Based on detecting the selection of the send action button 662, in operation 622, the user device 626 terminates the platform notification method 600 and initiates a chat session on an off-platform site.

[0118] In some examples, the user device 626 determines that there are two or more other users using the specified platform based on the chat status message data 656. Based on determining that there are two or more other users using the specified platform, the user device 626 provides two or more platform presence icons respectively associated with the two or more users using the specified platform (i.e., the platform presence icon is associated with each of the two or more users using the specified platform).

[0119] In some examples, the user device 626 uses the platform notification method 600 only when the chat user first starts a chat session using the specified platform. To this end, the user device 626 generates the text of the specified platform notification 636 based on the chat status message data 656. In some examples, the chat status message data 656 is provided once for each user in the chat session using the specified platform when the user participates in the chat session.

[0120] In some examples, if user device 626 receives multiple chat status messages in chat status message data 656 during the chat session, user device 626 connects the user identification of the designated platform user to generate designated platform notification 636. In some examples, based on detecting multiple chat status messages received at different times, user device 626 generates the text of designated platform notification 636 based on the most recently received chat status message.

[0121] Machine Architecture

[0122] Figure 7 700 within which instructions 702 (e.g., software, programs, applications, applet, app, or other executable code) may be executed for causing the machine 700 to perform any one or more of the methods discussed herein. For example, the instructions 702 may cause the machine 700 to perform any one or more of the methods described herein. The instructions 702 convert a general purpose, unprogrammed machine 700 into a specific machine 700 that is programmed to perform the functions described and illustrated in the manner described. The machine 700 may operate as a standalone device or may be coupled (e.g., networked) to other machines. In a networked deployment, the machine 700 may operate as 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 700 may include, but is not limited to, a server computer, a client computer, a personal computer (PC), a tablet computer, a laptop computer, a netbook, a set-top box (STB), a personal digital assistant (PDA), an entertainment media system, a cellular phone, a smart phone, a mobile device, a wearable device (e.g., a smart watch), a smart home device (e.g., a smart appliance), other smart devices, a web device, a network router, a network switch, a network bridge, or any machine capable of sequentially or otherwise executing instructions 702 specifying actions to be taken by the machine 700. In addition, although only a single machine 700 is shown, the term "machine" should also be taken to include a collection of machines that individually or jointly execute instructions 702 to perform any one or more of the methods discussed herein. For example, the machine 700 may include any of the plurality of server devices that form part of the interactive server system 110 or the user system 102. In some examples, the machine 700 may also include both a client system and a server system, wherein certain operations of a particular method or algorithm are performed on the server side, and certain operations of the particular method or algorithm are performed on the client side.

[0123] The machine 700 may include a processor 704, a memory 706, and an input / output (I / O) component 708 that may be configured to communicate with each other via a bus 710. In an example, the processor 704 (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 712 and a processor 714 that execute instructions 702. 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 7 Multiple processors 704 are shown, but machine 700 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.

[0124] The memory 706 includes a main memory 716, a static memory 718, and a storage unit 720, which are all accessible by the processor 704 via the bus 710. The main memory 706, the static memory 718, and the storage unit 720 store instructions 702 that implement any one or more of the methods or functions described herein. The instructions 702 may also reside, completely or partially, within the main memory 716, within the static memory 718, within a machine-readable medium 722 within the storage unit 720, within at least one of the processors 704 (e.g., within a cache memory of a processor), or within any suitable combination thereof during execution thereof by the machine 700.

[0125] The I / O components 708 may include various components for receiving input, providing output, generating output, sending information, exchanging information, capturing measurements, etc. The specific I / O components 708 included in a particular machine will depend on the type of 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 will be less likely to include such a touch input device.

The front-facing camera may, for example, be used to capture still images and videos of a user of user system 102 (e.g., “selfies”), which may then be enhanced with the enhancement data (e.g., filters) described above. For example, the rear-facing camera may be used to capture still images and videos in a more conventional camera mode, which images are similarly enhanced with the enhancement data. In addition to the front-facing camera and the rear-facing camera, user system 102 may also include a 360° camera for capturing 360° photos and videos.

[0129] Additionally, the camera system of the user system 102 may include dual rear cameras (e.g., a main camera and a depth sensing camera), or even triple, quad, or quintuple rear camera configurations on the front and back sides of the user system 102. For example, these multi-camera systems may include a wide-angle camera, an ultra-wide-angle camera, a telephoto camera, a macro camera, and a depth sensor.

[0131] Various technologies may be used to achieve communication. The I / O component 708 also includes a communication component 736 that is operable to couple the machine 700 to a network 738 or device 740 via a corresponding coupling or connection.

Similarly, the instructions 702 may be sent or received via a coupling (e.g., a peer-to-peer coupling) with the device 740 using a transmission medium.

[0135] Software Architecture

[0136] Figure 8 800 is a block diagram illustrating a software architecture 802 that may be installed on any one or more of the devices described herein. The software architecture 802 is supported by hardware such as a machine 804, which includes a processor 806, a memory 808, and an I / O component 810. In this example, the software architecture 802 may be conceptualized as a stack of layers, where each layer provides specific functionality. The software architecture 802 includes layers such as an operating system 812, a library 814, a framework 816, and an application 818. In operation, the application 818 activates an API call 820 through the software stack and receives a message 822 in response to the API call 820.

[0137] The operating system 812 manages hardware resources and provides public services. The operating system 812 includes, for example, a kernel 824, services 826, and drivers 828. The kernel 824 serves as an abstraction layer between the hardware and other software layers. For example, the kernel 824 provides memory management, processor management (e.g., scheduling), component management, networking and security settings, and other functions. Services 826 can provide other public services to other software layers. Drivers 828 are responsible for controlling or interfacing with the underlying hardware. For example, drivers 828 may include display drivers, camera drivers, or Low-power drivers, Flash drivers, Serial communication drivers (e.g., USB drivers), Drivers, audio drivers, power management drivers, etc.

[0138] The library 814 provides a low-level common infrastructure used by the application 818.

[0139] The framework 816 provides a high-level common infrastructure used by the applications 818. For example, the framework 816 provides various graphical user interface (GUI) functions, advanced resource management, and advanced location services. The framework 816 can provide a wide range of other APIs that can be used by the applications 818, some of which can be specific to a particular operating system or platform.

[0140] In an example, applications 818 may include a home application 836, a contacts application 838, a browser application 840, a book reader application 842, a location application 844, a media application 846, a messaging application 848, a game application 850, and a variety of other applications such as third-party applications 852. Applications 818 are programs that execute functions defined in the program. Various programming languages ​​can be used to create one or more of the applications 818 constructed in various ways, 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 specific example, third-party applications 852 (e.g., those created by entities other than the vendor of a particular platform using ANDROID TM or IOS TM Software Development Kit (SDK) can be used to develop applications on platforms such as IOS TM ANDROID TM , Mobile software running on the mobile operating system of the phone or other mobile operating system. In this example, the third-party application 852 can activate the API call 820 provided by the operating system 812 to facilitate the functions described herein.

[0141] Glossary

[0142] "Carrier signal" refers to any intangible medium that can store, encode or carry instructions for execution by a machine and includes digital or analog communications signals or other intangible media that facilitates communication of such instructions. Instructions may be sent or received over a network using a transmission medium via a network interface device.

[0143] "User device" refers to any machine that interfaces with a communications network to obtain resources from one or more server systems or other user devices. A client device may be, but is not limited to, a mobile phone, a desktop computer, a laptop computer, a portable digital assistant (PDA), a smart phone, a tablet computer, an ultrabook, a netbook, a laptop computer, a multiprocessor system, a microprocessor-based or programmable consumer electronics product, a game console, a set-top box, or any other communications device that a user may use to access a network.

[0144] "Communications network" means one or more parts of a network, which may be an ad hoc network, an intranet, an extranet, a virtual private network (VPN), a local area network (LAN), a wireless LAN (WLAN), a wide area network (WAN), a wireless WAN (WWAN), a metropolitan area network (MAN), the Internet, a part of the Internet, a part of the public switched telephone network (PSTN), a plain old telephone service (POTS) network, a cellular telephone network, a wireless network, A network, other type of network, or a combination of two or more such networks. For example, the network or a portion of the network may include a wireless network or a cellular network, and the coupling may be a code division multiple access (CDMA) connection, a global system for mobile communications (GSM) connection, or other type of cellular or wireless coupling. In this example, the coupling may implement any of various types of data transmission technologies, such as single carrier radio transmission technology (1xRTT), evolution data optimized (EVDO) technology, general packet radio service (GPRS) technology, enhanced data rate for GSM evolution (EDGE) technology, the third generation partnership project (3GPP) including 3G, fourth generation wireless (4G) network, universal mobile telecommunications system (UMTS), high speed packet access (HSPA), world wide interoperability for microwave access (WiMAX), long term evolution (LTE) standards, other data transmission technologies defined by various standard setting organizations, other long distance protocols, or other data transmission technologies.

[0145] "Component" refers to a logic or device, a physical entity with the following boundaries, which is defined by a function or subroutine call, a branch point, an API, or other technical definitions that provide partitioning or modularization for a specific processing or control function. A component can be combined with other components via its interface to perform machine processing. A component can be a packaged functional hardware unit designed for use with other components, and a part of a program that generally performs a specific function of a related function. A component can constitute a software component (e.g., a code implemented on a machine-readable medium) or a hardware component. A "hardware component" is a tangible unit that can perform certain operations and can be configured or arranged in a certain physical manner. In various examples, one or more computer systems (e.g., an independent computer system, a client computer system, or a server computer system) or one or more hardware components (e.g., a processor or a processor group) of a computer system can be configured by software (e.g., an application or an application part) to operate to perform certain operations as described herein. Hardware components can also be implemented mechanically, electronically, or in any suitable combination thereof. For example, a hardware component may include a dedicated circuit or logic that is permanently configured to perform certain operations. The hardware component may be a dedicated processor, such as a field programmable gate array (FPGA) or an application specific integrated circuit (ASIC). The hardware component may also include a programmable logic or circuit that is temporarily configured to perform certain operations by software. For example, the hardware component may include software executed by a general-purpose processor or other programmable processor. Once configured by such software, the hardware component becomes a specific machine (or a specific component of a machine), which is uniquely customized to perform the function of the configuration and is no longer a general-purpose processor. It will be recognized that it can be determined whether to mechanically implement the hardware component in a dedicated and permanently configured circuit or in a temporarily configured (e.g., configured by software) circuit for cost and time considerations. Therefore, the phrase "hardware component" (or "hardware-implemented component") should be understood to include a tangible entity, that is, an entity that is physically constructed, permanently configured (e.g., hardwired) or temporarily configured (e.g., programmed) to operate in some way or perform certain operations described herein. Considering an example in which a hardware component is temporarily configured (e.g., programmed), it is not necessary to configure or instantiate each hardware component in the hardware component at any one time. For example, where a hardware component includes a general purpose processor that is configured by software to be a special purpose processor, the general purpose processor may be configured as different special purpose processors (e.g., including different hardware components) at different times. The software configures a specific one or more processors accordingly, such as to constitute a specific hardware component at one time and to constitute different hardware components at different times. Hardware components may provide information to other hardware components and receive information from other hardware components. Thus, the described hardware components may be considered to be communicatively coupled.In the case of multiple hardware components being present at the same time, communication can be achieved by signal transmission between or among two or more hardware components (e.g., by appropriate circuits and buses). In examples 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 multiple hardware components and retrieving information in the memory structure. For example, a hardware component can perform an operation, and the output of the operation is stored in a memory device coupled to it in communication. Then, other hardware components can access the memory device at a subsequent time to retrieve the stored output and process it. The hardware component can also initiate communication with an input device or an output device, and can operate on resources (e.g., a collection of information). The various operations of the example methods described in this article can be performed at least in part by one or more processors that are temporarily configured (e.g., by software) or permanently configured to perform related operations. Whether it is temporarily configured or permanently configured, such a processor can constitute a processor-implemented component that operates to perform one or more operations or functions described herein. As used herein, "processor-implemented components" refer to hardware components implemented using one or more processors. Similarly, the method described in this article can be implemented at least in part by a processor, wherein one or more specific processors are examples of hardware. For example, at least some of the various operations of the method can be performed by one or more processors or the parts implemented by the processor. In addition, one or more processors can also operate to support the execution of related operations in a "cloud computing" environment or as a "software as a service" (SaaS) operation. For example, at least some operations in the operation can be performed by a computer group (as an example of a machine including a processor), wherein these operations can be accessed via a network (for example, the Internet) and via one or more appropriate interfaces (for example, API). The execution of some operations can be distributed between processors, not only resident in a single machine, but deployed across multiple machines. In some examples, a processor or a part implemented by a processor can be located in a single geographic location (for example, in a home environment, an office environment, or a server cluster). In other examples, a processor or a part implemented by a processor can be distributed across multiple geographic locations.

[0146] "Computer-readable storage media" refers to both machine storage media and transmission media. Therefore, these terms include both storage devices / media and carrier waves / modulated data signals. The terms "machine-readable medium", "computer-readable medium" and "device-readable medium" mean the same thing and may be used interchangeably in this disclosure.

[0147] "Ephemeral messages" are messages that are accessible for a limited duration. Ephemeral messages can be text, images, videos, etc. The access time for ephemeral messages can be set by the sender of the message. Alternatively, the access time can be a default setting or a setting specified by the recipient. Regardless of the setting technique, the message is ephemeral.

[0148] “Machine storage media” 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 is not limited to, solid-state memory and optical and magnetic media, including memory internal or external to the processor. Specific examples of machine storage media, computer storage media, and device storage media include: non-volatile memory, including, for example, semiconductor memory devices such as erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), FPGA, 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 media,” “device storage media,” and “computer storage media” mean the same thing and may be used interchangeably in this disclosure. The terms “machine storage media,” “computer storage media,” and “device storage media” explicitly exclude carrier waves, modulated data signals, and other such media, at least some of which are encompassed by the term “signal media.”

[0149] “Non-transitory computer-readable storage medium” refers to tangible media capable of storing, encoding, or carrying instructions to be executed by a machine.

[0150] "Signal medium" refers to any intangible medium that is capable of storing, encoding or carrying instructions executed by a machine and includes digital or analog communication signals or other intangible media that facilitate the communication of software or data. The term "signal medium" should be deemed to include any form of modulated data signals, carrier waves, etc. The term "modulated data signal" means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. The terms "transmission medium" and "signal medium" mean the same thing and may be used interchangeably in this disclosure.
