Description

[Technical Field]

[0001] The present disclosure relates to methods and systems for sharing content via instant messaging applications, and more particularly to methods and systems for granting a second user account access to content associated with a first user account of an instant messaging application. [Background technology]

[0002] With the proliferation of mobile devices such as smartphones and the development of the Internet, instant messaging applications have become widely used. Through chat rooms in such applications, multiple users can naturally communicate with each other in their daily lives and share various content such as their photos, pictures, videos, files, contacts, etc. In addition, multiple users can be included in multiple chat rooms consisting of different users and can share content with different users through each of the multiple chat rooms.

[0003] In conventional instant messaging applications, users had to directly upload images, text, files, etc. to a chat room to share their content with other users in the chat room. In such an environment, the number of pieces of content a user could share at one time was limited. Furthermore, in order to share content that had already been shared in another chat room, a user had to inconveniently read the content already shared in the other chat room and re-upload it to the chat room. Another problem was that users who shared content were passively provided with content they did not need. [Prior art documents] [Patent documents]

[0047] FIG. 1 illustrates an example in which a user 100 according to an embodiment of the present disclosure accesses content of other users through a talk room of an instant messaging application running on a user terminal 110. Through a talk room of the instant messaging application running on the user terminal 110, the user (or user account) 100 can access content associated with other users (or other user accounts) included in the talk room. Hereinafter, user 100 may refer to a second user or a second user account, and another user may refer to a first user or a first user account. Content associated with the first user may include images (or videos), files, and contacts stored on the first user's user terminal (not shown). Additionally or alternatively, content associated with the first user may include at least a portion of content associated with a talk room that includes the first user but not the second user.

[0048] In one embodiment, a second user 100 may request permission to access content associated with the first user from a first user included in the chat room via a chat room of an instant messaging application. For example, the second user 100 may transmit a permission request (e.g., a request indicating a desire to be granted access) for content associated with the first user to the user terminal of the first user. In this case, the second user 100 may select content for which permission is requested from among multiple pieces of content associated with the first user. Thus, the permission request transmitted to the user terminal of the first user may include information about the selected content (i.e., information about the content for which access is requested).

[0049] The user terminal of the first user (e.g., at least one processor of the user terminal) may receive a user input permitting access to content associated with the first user in response to an access permission request from the second user 100. Alternatively, the user terminal of the first user may receive a user input permitting the second user 100 to access content associated with the first user without an access permission request from the second user 100. The user terminal of the first user may then determine at least one piece of content to which the second user 100 is permitted to access, among a plurality of pieces of content associated with the first user. For example, the user terminal of the first user may determine at least one piece of content to which the first user is permitted to access, based on information about the content to which access is requested. In this case, the content to which the second user has requested access may be determined as the at least one piece of content to which the first user is permitted to access. Alternatively, the user terminal of the first user may determine at least one piece of content to which the first user is permitted to access, based on a user input from the first user selecting at least one piece of content from a plurality of pieces of content associated with the first user.

[0050] The user terminal of the first user may permit the second user 100 to access at least one of the determined contents. As a result, the second user 100 may access at least one of the plurality of contents associated with the first user. For example, the user terminal 110 of the second user 100 may output at least one of the plurality of contents associated with the first user via the second user's chat room. To this end, the user terminal 110 of the second user 100 and / or an information processing system connected to the user terminal of the first user may receive, from the user terminal of the first user, a request for permission to access the content associated with the first user (e.g., a request indicating that the second user's access is to be permitted). Thereafter, the information processing system may provide, via the chat room of the second user 100, a link enabling the second user 100 to access the content associated with the first user. Here, the accessible connecting link may include a connecting link that allows a user terminal 110 of the second user 100 to remotely connect to the user terminal of the first user.

[0051] As shown in the figure, when a second user 100 and "USER A" (i.e., a first user account) are included in "Chatroom X" of an instant messaging application, the second user 100 can access images of "USER A" via "Chatroom X." That is, at least a portion 122 of a plurality of images stored in the user terminal of "USER A" can be displayed on the screen 120 of the user terminal 110. Also, as shown in the figure, a message "You can access images of USER A" is displayed on the screen 120 of the user terminal 110, so that the second user 100 can recognize that access to images of "USER A" is permitted.

[0052] 1, at least a portion 122 of the plurality of contents associated with the first user is output in a lower region of the screen 120 of the user terminal 110, but is not limited to this. For example, at least a portion 122 of the plurality of contents associated with the first user may be output in the entire or partial region of the screen 120 of the user terminal 110.

[0053] 2 is a schematic diagram illustrating a configuration in which an information processing system 230 is communicably connected to multiple user terminals 210_1, 210_2, and 210_3 to provide a content sharing service according to an embodiment of the present disclosure.

[0057] In one embodiment, the information processing system 230 may receive, from the user terminals 210_1, 210_2, and 210_3 (e.g., user terminals associated with a first user account), a request for access permission for a second user account to content associated with the first user account (i.e., a request indicating an intention to grant access to the second user account). In one embodiment, the information processing system 230 may provide, to the user terminals 210_1, 210_2, and 210_3 (e.g., user terminals associated with the second user account), a connection link through which the second user account can access content associated with the first user account. For example, the information processing system 230 may provide a connection link through which the second user account can access content associated with the first user account via a first talk room of the second user account.

[0058] FIG. 3 is a block diagram showing the internal configuration of a user terminal 210 and an information processing system 230 according to an embodiment of the present disclosure. The user terminal 210 may refer to any computing device capable of executing an instant messaging application and capable of wired / wireless communication, and may include, for example, the mobile phone terminal 210_1, the tablet terminal 210_2, and the PC terminal 210_3 of FIG. 2. As shown in the figure, the user terminal 210 may include a memory 312, a processor 314, a communication module 316, and an input / output interface 318. Similarly, the information processing system 230 may include a memory 332, a processor 334, a communication module 336, and an input / output interface 338. As shown in FIG. 3, the user terminal 210 and the information processing system 230 may be configured to communicate information and / or data via the network 220 using their respective communication modules 316 and 336. Furthermore, the input / output device 320 may be configured to input information and / or data to the user terminal 210 and output information and / or data generated by the user terminal 210 via the input / output interface 318.

According to one embodiment, the memories 312 and 332 may include a permanent mass storage device such as a random access memory (RAM), a read only memory (ROM), a disk drive, a solid state drive (SSD), and a flash memory. As another example, a permanent mass storage device such as a ROM, an SSD, a flash memory, and a disk drive may be included in the user terminal 210 or the information processing system 230 as a separate permanent storage device distinct from the memory. The memories 312 and 332 may also store an operating system and at least one program code (e.g., code for an application related to an instant messaging service, a content sharing service, etc.).

[0060] These software components may be loaded from a computer-readable recording medium separate from the memories 312, 332. Such separate computer-readable recording media may include recording media directly connectable to the user terminal 210 and the information processing system 230, such as a floppy drive, a disk, a tape, a DVD / CD-ROM drive, and a memory card. As another example, the software components may be loaded into the memories 312, 332 via the communication modules 316, 336 rather than from a computer-readable recording medium. For example, at least one program may be loaded into the memories 312, 332 based on a computer program (e.g., an application related to an instant messaging service or a content sharing service) that is installed by a file provided via the network 220 by a developer or a file distribution system that distributes application installation files.

[0061] The processors 314, 334 may be configured to process computer program instructions by performing basic arithmetic, logic, and input / output operations. The instructions may be provided to the processors 314, 334 by the memories 312, 332 or the communications modules 316, 336. For example, the processors 314, 334 may be configured to execute instructions received by program code stored in a storage device, such as the memories 312, 332.

[0062] The communication modules 316 and 336 may provide configurations and functions for the user terminal 210 and the information processing system 230 to communicate with each other via the network 220, and may also provide configurations and functions for the user terminal 210 and / or the information processing system 230 to communicate with other user terminals or other systems (e.g., another cloud system, etc.). For example, a request or data (e.g., a request for access permission to content) generated by the processor 314 of the user terminal 210 via program code stored in a storage device such as the memory 312 may be transmitted to the information processing system 230 via the network 220 under the control of the communication module 316. Conversely, a control signal or command provided under the control of the processor 334 of the information processing system 230 may be received by the user terminal 210 via the communication module 316 of the user terminal 210 via the communication module 336 and the network 220. For example, the user terminal 210 may receive a link from the information processing system 230 that allows access to content.

[0063] The input / output interface 318 may be a means for interfacing with the input / output device 320. For example, the input device may include a device such as a camera including an audio sensor and / or an image sensor, a keyboard, a microphone, a mouse, etc., and the output device may include a device such as a display, a speaker, a haptic feedback device, etc. As another example, the input / output interface 318 may be a means for interfacing with a device that integrates components or functions for performing input and output, such as a touch screen. Although FIG. 3 illustrates the input / output device 320 as not being included in the user terminal 210, the present invention is not limited thereto and may be configured integrally with the user terminal 210. Furthermore, the input / output interface 338 of the information processing system 230 may be a means for connecting to the information processing system 230 or for interfacing with an input or output device (not shown) that may be included in the information processing system 230. Although FIG. 3 shows the input / output interfaces 318, 338 as elements configured separately from the processors 314, 334, this is not limiting and the input / output interfaces 318, 338 may also be configured to be included in the processors 314, 334.

[0064] The user terminal 210 and the information processing system 230 may include more components than those shown in FIG. 3 . However, it is not necessary to explicitly show most of the conventional components. According to one embodiment, the user terminal 210 may be embodied to include at least a portion of the input / output device 320 described above. The user terminal 210 may also include other components such as a transceiver, a global positioning system (GPS) module, a camera, various sensors, and a database. For example, if the user terminal 210 is a smartphone, it may include components typically found in smartphones. For example, the user terminal 210 may be embodied to further include various components such as an acceleration sensor, a gyro sensor, a microphone module, a camera module, various physical buttons, buttons using a touch panel, input / output ports, and a vibrator for vibration.

[0065] According to one embodiment, the processor 314 of the user terminal 210 may be configured to run an instant messaging application that provides an instant messaging service. In this case, program code associated with the application may be loaded into the memory 312 of the user terminal 210. When the application is running, the processor 314 of the user terminal 210 may receive information and / or data provided by the input / output device 320 via the input / output interface 318 or from the information processing system 230 via the communication module 316, process the received information and / or data, and store it in the memory 312. Such information and / or data may also be provided to the information processing system 230 via the communication module 316.

[0066] When the instant messaging application is operated, the processor 314 may receive voice data, text, images, videos, etc. input or selected by an input device such as a touch screen, keyboard, camera including an audio sensor and / or image sensor, microphone, etc. coupled to the input / output interface 318, and may store the received voice data, text, images, and / or videos in the memory 312 or provide them to the information processing system 230 via the communication module 316 and the network 220. In one embodiment, the processor 314 may receive a user input, input by the input device, granting access to content associated with a first user account included in a first talk room of the instant messaging application, and provide a request indicated by the user input (e.g., a request indicating an intention to grant access) to the information processing system 230 via the network 220 and the communication module 316.

[0067] In one embodiment, the processor 314 can determine at least one piece of content to which the first user account is permitted access from among a plurality of pieces of content associated with the first user account. In one embodiment, the processor 314 can grant a second user account included in the first talk room access to the determined at least one piece of content. For example, the processor 314 can forward a request for granting access to the determined at least one piece of content from the second user account (e.g., a request indicating that the second user account is to be granted access) to the information processing system 230.

[0068] The processor 314 of the user terminal 210 can output information and / or data by transferring it to the input / output device 320 via the input / output interface 318. For example, the processor 314 of the user terminal 210 can output the processed information and / or data via the output device 320, such as a display-capable device (e.g., a touch screen or display) or an audio-capable device (e.g., a speaker).

[0069] The processor 334 of the information processing system 230 may be configured to manage, process, and / or store information and / or data received from multiple user terminals 210 and / or multiple external systems. The information and / or data processed by the processor 334 may be provided to the user terminal 210 via the communication module 336 and the network 220. In one embodiment, the processor 334 may receive, from a first user account included in a first talk room of an instant messaging application, a request for permission to access content associated with the first user account from a second user account (e.g., a request indicating an intention to grant access to the second user account). Here, the second user account may be included in the first talk room. Furthermore, the content associated with the first user account may include content associated with a second talk room in which the first user account is included. In one embodiment, the processor 334 may provide a link through which the second user account can access content associated with the first user account via the first talk room of the second user account. Here, the accessible connecting link may include a connecting link that allows a second user terminal associated with the second user account to remotely connect to a first user terminal associated with the first user account.

[0070] In one embodiment, the processor 334 may transmit a message regarding whether the second user account is authorized to access content associated with the second talk room to a third user account included in the second talk room and receive a response regarding whether the access is authorized from the third user account. The processor 334 may then provide a link through which the second user account can access content associated with the second talk room via the first talk room of the second user account based on the received response from the third user account (e.g., a response indicating that access is authorized, a request indicating that access is being authorized, etc.). Alternatively, if the processor 334 receives a request to block access (i.e., an access blocking request) from the third user account, it may block the second user account's access to content associated with the second talk room.

[0071] In one embodiment, the processor 334 may generate an analysis result for text included in the first chat room, and transmit a message regarding whether the second user account has access to content associated with the first user account via the first chat room of the first user account based on the generated analysis result. In one embodiment, the processor 334 may determine a range of recommended content based on the analysis result for at least one of the content associated with the first user account or the text included in the first chat room, and provide the determined range of recommended content via the first chat room of the first user account.

[0072] 4 is a flowchart illustrating a content sharing method 400 according to one embodiment of the present disclosure. In one embodiment, the content sharing method 400 may be performed by a processor (e.g., at least one processor of a user terminal). In another embodiment, the content sharing method 400 may be performed by at least one processor of an information processing system. In still another embodiment, the content sharing method 400 may be performed by at least one processor of the user terminal and at least one processor of the information processing system while communicating information required for content sharing with each other.

[0073] The content sharing method 400 may begin by receiving user input granting access to content associated with a first user account included in a first talk room of an instant messaging application (S410). For example, the processor may receive the user input granting access to the content associated with the first user account in response to a message regarding whether or not a second user account is authorized to access the content and / or a message regarding a request for authorization.

[0074] Next, the processor may determine at least one piece of content to which access is permitted from among a plurality of pieces of content associated with the first user account (S420). Here, the at least one piece of content may include content associated with a second chat room in which the first user account is included. Additionally, the processor may determine an access permission expiration date for the determined at least one piece of content. In one embodiment, the processor may receive a user input selecting at least one piece of content to which access is permitted from among a plurality of pieces of content associated with the first user account, and in response thereto, determine at least one piece of content to which access is permitted from among a plurality of pieces of content associated with the first user account.

[0075] The processor then permits a second user account included in the first talk room to access the at least one piece of content determined in step S420 (S430). For example, if the current time is within the access permission period, the processor permits the second user account to access the at least one piece of content. This allows the at least one piece of content to be output via the first talk room of the second user account.

[0076] In one embodiment, a message regarding whether or not access to content associated with the second talk room is transmitted to a third user account included in the second talk room, and the processor grants the second user account access to the content associated with the second talk room based on the access permission request from the third user account. At this time, a message indicating that the second user account is accessing the content associated with the second talk room may be output via the second talk room. Alternatively, a message regarding whether or not access to content associated with the second talk room is transmitted to a third user account included in the second talk room, and the processor may block the second user account's access to the content associated with the second talk room based on the access blocking request from the third user account.

[0077] In one embodiment, a processor may receive a request for access permission to content associated with a first user account from a second user account and output a message regarding the access permission request received via a first chat room of the first user account. The processor may then receive a user input granting access to the content associated with the first user account in response to the output message. Here, the access permission request may include information regarding the content for which access is requested by the second user account. In this case, the processor may determine at least one piece of content to which access is permitted from among a plurality of pieces of content associated with the first user account, based on the information regarding the content for which access is requested by the second user account.

[0078] In one embodiment, the processor may output a message regarding whether or not the second user account is authorized to access content associated with the first user account via the first chat room of the first user account based on the analysis result of the text included in the first chat room. In this case, the processor may receive a user input permitting access to the content associated with the first user account in response to the output message regarding whether or not the second user account is authorized to access the content associated with the first user account.

[0079] In one embodiment, the processor may output a range of recommended content via the first chat room based on an analysis result of at least one of content associated with the first user account or text included in the first chat room, and determine at least one piece of content to which access is permitted by selecting at least one piece of content from the output range of recommended content. For example, the processor may determine at least one piece of content to which access is permitted based on user input selecting at least one piece of content from the output range of recommended content.

[0080] In one embodiment, the processor can output a message indicating that the second user account is accessing the determined at least one piece of content via the first talk room of the first user account. Additionally or alternatively, the processor can receive a user input blocking access to the at least one piece of content and, based on such user input, block the second user account's access to the at least one piece of content.

[0081] 5 illustrates example operations 510 and 520 for granting access to content from other users or requesting access to content from other users, according to one embodiment of the present disclosure. In one embodiment, a user may grant access to his / her content to other users in a chat room via a chat room of an instant messaging application. In another embodiment, a user may request access to content from other users in the chat room via a chat room of an instant messaging application.

[0082] As shown in a first operation 510, a processor (e.g., at least one processor of a user terminal) can display a button 512 associated with "access to content" on a display via "Chatroom X." The processor can then receive user input on the button 512 associated with "access to content" displayed on the display. In response to such user input, the processor can display a "Grant access to my content" button 522 and a "Request access to content" button 524 on the display, as shown in a second operation 520.

[0083] In one embodiment, the user allows at least some of the other users (or user accounts) included in "Chatroom X" to access at least one of the plurality of pieces of content associated with the user by touching an "Allow access to my content" button 522 shown in the second operation 520. In another embodiment, the user can request at least some of the other users (or user accounts) included in "Chatroom X" to grant access to at least one of the plurality of pieces of content associated with the user by touching a "Request access to content" button 524 shown in the second operation 520.

[0084] FIG. 6 is a diagram illustrating an example of determining content to which access is permitted according to an embodiment of the present disclosure. In one embodiment, a processor (e.g., at least one processor of a user terminal) may receive a user input selecting at least one piece of content to which access is permitted from among a plurality of pieces of content associated with a first user account. In response to the user input, the processor may determine at least one piece of content to which access is permitted from among a plurality of pieces of content associated with the first user account. The processor then permits a second user account included in the first chat room to access the determined at least one piece of content. Here, the content associated with the first user account may include files, contacts, photos, etc. stored on the user terminal of the first user account. Additionally or alternatively, the content associated with the first user account may include content stored in a storage space (e.g., a cloud storage space, an external storage device, etc.) of the first user account and / or content associated with a chat room to which the first user account belongs.

[0085] In one embodiment, the at least one piece of content to which access is permitted may refer to an item of content itself, such as a file item 612, a contact item 614, a photo item 618, etc., associated with the first user account, the storage space 616 of the first user account itself, and / or each of the chat rooms 620, 622, 624 to which the first user account belongs. For example, when the file item 612, the contact item 614, the photo item 618, etc. are selected, the content to which access is permitted may refer to content stored in the user terminal to which the first user account is connected (i.e., the user terminal associated with the first user account), and may be determined as, for example, all or part of a file, all or part of a contact, all or part of an image (photo or video), etc. As shown in the figure, the processor can display on the display buttons associated with a file item 612, a contact item 614, a storage space 616, a photo item 618, Chat A (620), Chat B (622), and Chat C (624) as multiple pieces of content associated with the first user account. Then, in response to receiving user input (e.g., touch input, etc.) on a portion of the multiple buttons displayed on the display (e.g., the button associated with photo item 618), the processor can determine that item (e.g., photo item 618) is at least one piece of content to which access is permitted. Thus, the processor permits the second user account to access all of the content included in photo item 618 of the first user.

[0086] The processor can determine an access permission expiration date 628 for the determined at least one piece of content. For example, the access permission expiration date 628 can include a time period such as one hour, one day, one week, or one month, and / or an end date (or a start date) corresponding to a specific point in time, such as "2021.01.22." In one embodiment, the processor can receive user input for setting the access permission expiration date 628 and determine the access permission expiration date 628 for the at least one piece of content in response thereto. For example, the first user account can set the access permission expiration date 628 for the content by directly inputting (e.g., text inputting) the access permission expiration date 628 using an input device. Alternatively, the first user account can set the access permission expiration date 628 for the content by selecting at least one of the time periods included in the list for the access permission expiration date 628.

[0087] When an access permission deadline 628 for content is set, the processor permits the second user account to access at least one piece of content only if the current time (e.g., the current time on the user terminal) is within the access permission deadline 628. For example, by a user input (e.g., touch input, etc.) of the first user account that sets the access permission deadline 628 to "1 hour," the access permission deadline 628 can be determined as "1 hour" as shown in the figure. In this case, the second user account is permitted to access at least one piece of content for one hour from the access permission start time.

[0088] 6, when a first user account grants access to content (e.g., immediately before or after granting access), the at least one content to which the second user account is granted access and the access permission deadline 628 can be determined by selecting at least one content to which access is granted and the access permission deadline 628. For example, when the second user account requests access to content (i.e., a request indicating a desire to be granted access), the at least one content to which access is granted and / or the access permission deadline can be determined based on information about the selected content (i.e., the content for which access permission is requested) and / or the access permission deadline.

[0089] FIG. 7 is a diagram illustrating an example of determining content to which access is permitted according to an embodiment of the present disclosure. In one embodiment, the at least one piece of content to which access is permitted may include each individual piece of content included in a content item, each individual piece of content included in a chat room to which the first user account belongs, and each individual piece of content included in a storage space of the first user account. For example, when the first user account selects a button for a photo item among buttons for content items (or chat rooms or storage spaces) displayed on a display, a processor (e.g., at least one processor of a user terminal) can output multiple images stored on the user terminal on the display. Then, as shown in the figure, when the first user account selects (e.g., by touch input, drag input, etc.) at least some 712 of the multiple images, the processor allows the second user account to access at least some of the selected images 712.

[0090] In one embodiment, the processor may output a range of recommended content through a first chat room of the first user account based on an analysis result of at least one of content associated with the first user account or text included in the first chat room. To this end, the information processing system and / or the processor may determine a range of recommended content based on an analysis result of at least one of content associated with the first user account or text included in the first chat room, and provide the determined range of recommended content through the first chat room of the first user account. The information processing system and / or the processor may use various image analysis algorithms, text analysis algorithms, etc. to analyze at least one of content associated with the first user account or text included in the first chat room. The processor may then determine at least one piece of content to which access is permitted by receiving user input (e.g., touch input, drag input, etc.) selecting at least one piece of content from the output range of recommended content.

[0091] For example, the processor can determine, among a plurality of images stored on the user terminal of the first user account, images that include (or are photographed by) at least a portion of the user account included in the first talk room as the range of recommended content, and output the range of recommended content via the first talk room of the first user account. To this end, the information processing system can determine, based on a person analysis result included in each of the plurality of images, images that include (or are photographed by) at least a portion of the user account included in the first talk room as the range of recommended content, and provide the determined range of recommended content via the first talk room of the first user account.

[0092] As another example, the processor may determine, based on the analysis result of the text "assignment" included in the first chat room, file items associated with the first user account (or documents stored on the user terminal containing the text "assignment") as a range of recommended content, and output the range of recommended content via the first chat room of the first user account. To this end, the information processing system may determine, based on the analysis result of the text included in the first chat room, file items associated with the first user account (or documents stored on the user terminal containing the text "assignment") as a range of recommended content, and provide the determined range of recommended content via the first chat room of the first user account.

[0093] 8 illustrates an example of receiving an access permission request from another user account according to an embodiment of the present disclosure. In one embodiment, a processor (e.g., at least one processor of a user terminal) may receive an access permission request from a second user account to access content associated with a first user account. Accordingly, the processor may output a message 812 regarding the access permission request received via a first chat room of the first user account. In response to the output message 812, the processor may receive a user input granting access to the content associated with the first user account.

[0094] The access permission request received from the second user account may include information about the content to which the second user account has requested access. The processor may determine at least one piece of content to which the first user account is permitted access based on the information about the content to which access has been requested. That is, the second user account may select the content to which it wishes to request access from the plurality of pieces of content associated with the first user account and transmit a request for access permission for the selected content to the second user account. If the first user account then permits the second user account to access the selected content, the processor may permit the second user account to access the selected content. Alternatively, the first user account may reselect the at least one piece of content to which it is permitted access and permit the second user account to access the selected content. In this case, the processor may permit the second user account to access only the reselected at least one piece of content.

[0095] As shown in a first operation 810, the processor can output a message 812 via "Chatroom X" saying, "USER A is requesting access permission to a document file" by receiving a request from "USER A" for access permission to the user's document file. The message 812 can include a "Details" button 814, an "Allow Access" button 816, and a "Deny Access" button 818. If the user touches the "Allow Access" button 816 included in the message 812, the processor can allow "USER A" to access the user's document file. Additionally, if the user modifies the access permission conditions and / or access permission information, such as the content to which access is permitted, the access permission expiration date, and the user to whom access is permitted, before or after touching the "Allow Access" button 816 included in the message 812, the processor can allow "USER A" to access the user's document file based on the modified access permission conditions and / or access permission information. On the other hand, if the user touches the "Deny Access" button 818 included in the message 812, the processor does not allow "USER A" to access the user's document file. Additionally, if the user touches the "Details" button 814 included in the message 812, the processor can output detailed information about "USER A's" access permission request, such as information about the content to which access is requested, the requested access permission expiration date, etc.

[0096] In one embodiment, the processor may output a message 822 indicating that the second user account is accessing the determined at least one piece of content via the first talk room of the first user account. For example, the processor may output a message indicating that the second user account is accessing at least one piece of content associated with the first user account in real time (e.g., content is being output to a user terminal of the second user account or content is being downloaded) via the first talk room of the first user account. Additionally or alternatively, the processor may output a message indicating that the second user account is in a state where it can access (i.e., access is permitted to) at least one piece of content associated with the first user account.

[0097] As shown in second operation 820, the processor can output a message 822 via "Chatroom X" stating, "USER A is permitted to access the document file." Such message 822 allows the user to recognize that "USER A" has access to his or her document file. The message 822 can include a "Details" button 824 and a "Restrict Access" button 826. For example, if the user touches the "Details" button 824, the processor can output detailed information such as the content (or range of content) to which access is permitted, the content that "USER A" is currently accessing in real time, and the access permission expiration date. Additionally, the processor can receive a user input to block access to at least one piece of content, and based on such user input, can block the second user account's access to at least one piece of content. For example, if the user touches the "Restrict Access" button 826, the processor can block "USER A"'s access to the document file.

[0098] 8 illustrates an example in which one of multiple user accounts included in a chat room is permitted to access at least one piece of content, but this is not limiting. For example, all or some of multiple user accounts included in a chat room may be permitted to access at least one piece of content.

[0099] 9 is a diagram illustrating an example in which a message 914 regarding whether or not access is permitted is output based on an analysis result of text included in a chat room according to an embodiment of the present disclosure. In one embodiment, a processor (e.g., at least one processor of a user terminal) may output a message 914 regarding whether or not a second user account is permitted to access content associated with the first user account via a first chat room of the first user account based on an analysis result of text 912 included in the first chat room. To this end, the information processing system and / or the processor may generate an analysis result of the text 912 included in the first chat room and, based on the generated analysis result, transmit a message 914 regarding whether or not the second user account is permitted to access content associated with the first user account via the first chat room of the first user account. In this case, at least one piece of content to which access is permitted and / or an access permission period may be automatically determined based on the analysis result. For example, the processor may determine an image including location information corresponding to "Yeosu" as the at least one piece of content to which access is permitted based on an analysis result of the text "Yeosu travel photo" included in the chat room of the first user account. Alternatively, the at least one piece of content to which access is permitted and / or the access permission period may be automatically determined as default values.

[0100] As shown in the figure, based on the analysis results of text 912 by "USER A" contained in "Chatroom X," "I want to see the photos I took yesterday," the processor can output a message ("Do you want to allow USER A to access the images taken (or saved) yesterday (e.g., "2021.01.01") 914 regarding whether or not "USER A" should be granted access to the images taken (or saved) yesterday among the multiple images contained in the user terminal ("Do you want to allow USER A to access the images taken (or saved) yesterday?"). To this end, the information processing system and / or processor can generate text analysis results for "yesterday," "photo," and / or "I want to see" among the text contained in "Chatroom X," and based on the generated analysis results, transmit a message 914 via the user's "Chatroom X" regarding whether or not "USER A" should be granted access to the images taken (or saved) yesterday among the multiple images. In other words, the access permission request can be fulfilled by automatically recognizing "USER A's" intent through text analysis, etc., without "USER A" having to directly perform a separate task to request access permission.

[0101] Thereafter, based on the first user account's response to the message 914, the processor can determine whether to grant access to the second user account to the content associated with the first user account. For example, the processor can receive user input to grant access to the content associated with the first user account in response to the output message 914 regarding granting or denying access to the content. As shown in the figure, the message 914 regarding granting or denying access to the content can include a "Details" button 916, a "Allow Access" button 918, and a "Deny Access" button 920. For example, if the user touches the "Allow Access" button 918, the processor can grant "USER A" access to images taken on 2021.01.01 stored on the user terminal. In contrast, if the user touches the "Deny Access" button 920, the processor can deny "USER A" access to images taken on 2021.01.01 stored on the user terminal. Additionally, if the user touches the "Details" button 916, the processor can output detailed information, such as information about the content associated with the access permission, a deadline, etc.

[0102] 10 is a diagram illustrating an example in which a message 1012 regarding permission to access content associated with a chat room and a message 1022 indicating that content associated with the chat room is being accessed are output, according to an embodiment of the present disclosure. The at least one content to which access is permitted may include content associated with a second chat room (e.g., "Chatroom Y") that includes a first user account (e.g., "USER B") but not a second user account (e.g., "USER A"). That is, the second user account may request permission to access content associated with the second chat room including the first user account through the first chat room (e.g., a chat room including the first and second user accounts). Here, the content associated with the second chat room may include content shared through the second chat room, content stored in the storage space of the second chat room, text (i.e., conversation content) included in the second chat room, content associated with user accounts included in the second chat room, etc. In one embodiment, for the second user account's access permission to content associated with the second talk room, a message 1012 regarding whether or not access permission to content associated with the second talk room (e.g., all or part of the content in the talk room) may be transmitted to a third user account included in the second talk room. Here, the third user account may include one or more user accounts included in the second talk room.

[0103] In one embodiment, a processor (e.g., at least one processor of a user terminal) allows a second user account to access content associated with a second talk room based on a request for access permission (i.e., a request indicating an intention to grant access) from a third user account. In contrast, the processor can block the second user account's access to content associated with the second talk room based on a request for access blocking from the third user account. For example, if all of the multiple third user accounts allow the second user account to access the content associated with the second talk room, the processor allows the second user account to access the content associated with the second talk room. Alternatively, if a majority of the multiple third user accounts allow the second user account to access the content associated with the second talk room, the processor allows the second user account to access the content associated with the second talk room. Thus, the second user account is allowed to access the content associated with the second talk room only if permission is granted by not only the first user account but also the third user account.

[0104] To this end, the information processing system (e.g., at least one processor of the information processing system) can forward a message regarding whether the second user account has access to content associated with the second talk room to a third user account included in the second talk room, receive a response regarding whether the access is allowed (e.g., an access permission request or an access blocking request) from the third user account, and, based on the response received from the third user account, provide a connecting link through which the second user account can access the content associated with the second talk room via the first talk room of the second user account.

[0105] As shown in a first operation 1010, when a user account included in "Chatroom Y" (i.e., the first user account and / or the third user account) receives a message regarding whether or not access is permitted to content related to "Chatroom Y," the user terminal of the user account can output a message 1012 stating, "USER A is requesting access permission to Chatroom Y" via "Chatroom Y." The message 1012 can include a "Details" button, an "Allow Access" button 1014, and a "Deny Access" button 1016. For example, if all user accounts included in "Chatroom Y" select the "Allow Access" button 1014, "USER A" is permitted to access content related to "Chatroom Y." In contrast, if some of the user accounts included in "Chatroom Y" select the "Deny Access" button 1016, "USER A" is not permitted to access content related to "Chatroom Y."

[0106] In one embodiment, a message 1022 indicating that the second user account is accessing content related to the second chat room may be output via the second chat room of the first user account and / or the third user account. As shown in second operation 1020, a message 1022 stating "USER A's access to Chatroom Y is permitted" may be output via "Chatroom Y" of a user account included in "Chatroom Y." This message 1022 allows the user accounts included in "Chatroom Y" to recognize that "USER A" is allowed to access content related to "Chatroom Y." The message 1022 may include a "Details" button and a "Restrict Access" button 1024. If some of the user accounts included in "Chatroom Y" select the "Restrict Access" button 1024, "USER A's" access to content related to "Chatroom Y" may be blocked.
