For example, the processor (314, 334) may be configured to execute instructions received according to program code stored in a recording device such as memory (312, 332).

[0061] The communication module (316, 336) may provide a configuration or function for the user terminal (210) and the information processing system (230) to communicate with each other via the network (220), and may provide a configuration or function for the user terminal (210) and / or the information processing system (230) to communicate with another user terminal or another system (e.g., a separate cloud system). For example, a request or data (e.g., a request for permission to access content) generated by the processor (314) of the user terminal (210) according to program code stored in a recording device such as 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) can be received by the user terminal (210) through the communication module (336) and the network (220) via the communication module (316) of the user terminal (210). For example, the user terminal (210) can receive a connection link that allows access to content from the information processing system (230).

[0062] The input / output interface (318) may be a means for interfacing with an input / output device (320). As an 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, or a mouse, and the output device may include a device such as a display, a speaker, or a haptic feedback device. As another example, the input / output interface (318) may be a means for interfacing with a device in which the configuration or function for performing input and output is integrated into one, such as a touchscreen. Although the input / output device (320) is depicted in FIG. 3 as not being included in the user terminal (210), it is not limited thereto and may be configured as a single device with the user terminal (210). Additionally, the input / output interface (338) of the information processing system (230) may be a means for interfacing with a device (not shown) for input or output that is connected to the information processing system (230) or that the information processing system (230) may include. In FIG. 3, the input / output interface (318, 338) is shown as an element configured separately from the processor (314, 334), but is not limited thereto, and the input / output interface (318, 338) may be configured to be included in the processor (314, 334).

[0063] The user terminal (210) and the information processing system (230) may include more components than those of FIG. 3. However, it is not necessary to clearly illustrate most of the prior art components. In one embodiment, the user terminal (210) may be implemented to include at least some of the input / output devices (320) described above. Additionally, the user terminal (210) may further include other components such as a transceiver, a GPS (Global Positioning System) module, a camera, various sensors, a database, etc. For example, if the user terminal (210) is a smartphone, it may include components that are generally included in a smartphone, and may be implemented to include various components such as an accelerometer, a gyroscope, a microphone module, a camera module, various physical buttons, buttons using a touch panel, input / output ports, and a vibrator for vibration.

[0064] According to one embodiment, the processor (314) of the user terminal (210) may be configured to operate an instant messaging application that provides instant messaging services. At this time, program code associated with the application may be loaded into the memory (312) of the user terminal (210). While the application is operating, the processor (314) of the user terminal (210) may receive information and / or data provided from an input / output device (320) through an input / output interface (318) or receive information and / or data from an information processing system (230) through a communication module (316), and may process the received information and / or data and store it in the memory (312). Additionally, such information and / or data may be provided to the information processing system (230) through the communication module (316).

[0065] While the instant messaging application is in operation, the processor (314) may receive voice data, text, images, videos, etc., that are input or selected through an input device such as a touch screen, keyboard, audio sensor and / or image sensor, camera, microphone, etc., connected to the input / output interface (318), and may store the received voice data, text, images and / or videos, etc. in memory (312) or provide them to an information processing system (230) through a communication module (316) and a network (220). In one embodiment, the processor (314) may receive a user input that allows access to content associated with a first user account included in a first chat room of the instant messaging application input through an input device, and may provide a request indicated by the user input (e.g., a request indicating that access is to be allowed) to an information processing system (230) through a network (220) and a communication module (316).

[0066] In one embodiment, the processor (314) may determine at least one piece of content to be allowed access among a plurality of pieces of content associated with the first user account. In one embodiment, the processor (314) may allow the second user account included in the first chat room to access the determined at least one piece of content. For example, the processor (314) may transmit a request to allow the second user account access to the determined at least one piece of content (for example, a request indicating that access to the second user account is to be allowed) to the information processing system (230).

[0067] The processor (314) of the user terminal (210) can transmit information and / or data to an input / output device (320) through an input / output interface (318) and output it. For example, the processor (314) of the user terminal (210) can output the processed information and / or data through an output device (320), such as a display output device (e.g., touch screen, display, etc.) or a voice output device (e.g., speaker).

[0068] The processor (334) of the information processing system (230) may be configured to manage, process, and / or store information and / or data received from a plurality of user terminals (210) and / or a plurality of external systems. The information and / or data processed by the processor (334) may be provided to the user terminals (210) through a communication module (336) and a network (220). In one embodiment, the processor (334) may receive a request to allow access to content associated with the first user account from a first user account included in a first chat room of an instant messaging application (e.g., a request indicating an intention to allow access to the second user account). Here, the second user account may be included in the first chat room. Additionally, the content associated with the first user account may include content associated with the second chat room in which the first user account is included. In one embodiment, the processor (334) may provide a connection link through the first chat room of the second user account that enables the second user account to access content associated with the first user account. Here, the accessible connection link may include a connection link that enables remote access to the first user terminal associated with the first user account by the second user terminal associated with the second user account.

[0069] In one embodiment, the processor (334) may send a message to a third user account included in the second chat room regarding whether to allow access to content associated with the second chat room, and receive a response from the third user account regarding whether to allow access. Afterward, based on the received response from the third user account (e.g., a response indicating permission to access, a request indicating an intention to allow access, etc.), the processor (334) may provide a connection link through the second user account's first chat room that allows the second user account to access content associated with the second chat room. Alternatively, if the processor (334) receives a request from the third user account to block access (i.e., an access blocking request), it may block access to content associated with the second chat room by the second user account.

[0070] In one embodiment, the processor (334) generates an analysis result for text included in the first chat room and, based on the generated analysis result, can transmit a message regarding whether to allow access to content associated with the first user account by the second user account through the first chat room of the first user account. In one embodiment, the processor (334) determines the range of recommended content based on an analysis result for at least one of the content associated with the first user account or text included in the first chat room, and can provide the determined range of recommended content through the first chat room of the first user account.

[0071] FIG. 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 yet another embodiment, the content sharing method (400) may be performed by at least one processor of a user terminal and at least one processor of an information processing system communicating information required for content sharing with each other.

[0072] The content sharing method (400) may be initiated by receiving user input that allows access to content associated with a first user account included in a first chat room of an instant messaging application (S410). For example, the processor may receive user input that allows access to content associated with the first user account in response to a message regarding whether to allow access to a second user account and / or a message regarding a request for access permission.

[0073] Then, the processor may determine at least one piece of content to be allowed access 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 containing the first user account. Additionally, the processor may determine a period for allowing access to the determined at least one piece of content. In one embodiment, the processor receives user input selecting at least one piece of content to be allowed access among a plurality of pieces of content associated with the first user account, and in response thereto, may determine at least one piece of content to be allowed access among a plurality of pieces of content associated with the first user account.

[0074] The processor may allow a second user account included in the first chat room to access at least one determined piece of content (S430). For example, if the current time falls within the access permission period, the processor may allow the second user account to access at least one piece of content. Accordingly, at least one piece of content may be output through the second user account's first chat room.

[0075] In one embodiment, a message regarding whether to allow access to content associated with the second chat room may be transmitted to a third user account included in the second chat room, and the processor may allow the second user account to access the content associated with the second chat room based on the access permission request from the third user account. In this case, a message indicating that the second user account is accessing the content associated with the second chat room may be output through the second chat room. Alternatively, a message regarding whether to allow access to content associated with the second chat room may be transmitted to a third user account included in the second chat room, and the processor may block the second user account's access to the content associated with the second chat room based on the access block request from the third user account.

[0076] In one embodiment, the processor receives a request from a second user account to allow access to content associated with a first user account and may output a message regarding the access permission request received through the first chat room of the first user account. Subsequently, the processor may receive user input allowing access to 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, based on the information regarding the content for which access is requested by the second user account, the processor may determine at least one content among a plurality of contents associated with the first user account to be allowed access.

[0077] In one embodiment, the processor may output a message regarding whether to allow access to content associated with the first user account through the first chat room of the first user account, based on the analysis result of text included in the first chat room. In this case, the processor may receive user input allowing access to content associated with the first user account in response to the output message regarding access permission.

[0078] In one embodiment, the processor may output a range of recommended content through the first chat room based on an analysis result of at least one of the content associated with the first user account or text included in the first chat room, and determine at least one content to be allowed access by selecting at least one content from the output range of recommended content. For example, the processor may determine at least one content to be allowed access based on user input selecting at least one content from the output range of recommended content.

[0079] In one embodiment, the processor may output a message indicating that a second user account is accessing at least one determined content through a first chat room of a first user account. Additionally or alternatively, the processor may receive user input blocking access to at least one content, and based on such user input, access by the second user account to at least one content may be blocked.

[0080] FIG. 5 is a diagram illustrating an example of an operation (510, 520) for allowing another user access to content or requesting access to content by another user according to an embodiment of the present disclosure. In one embodiment, a user may allow another user included in a chat room to access their content through a chat room of an instant messaging application. In another embodiment, a user may request access to content by another user included in a chat room through a chat room of an instant messaging application.

[0081] As illustrated in the first operation (510), a processor (e.g., at least one processor of a user terminal) may display a button (512) associated with 'content access' via 'Chatroom X' on the display. Subsequently, the processor may receive user input regarding the button (512) associated with 'content access' displayed on the display. In response to this user input, the processor may display a 'Allow access to my content' button (522) and a 'Request access to content' button (524) on the display, as illustrated in the second operation (520).

[0082] In one embodiment, the user may allow at least some of the other users (or user accounts) included in 'Chatroom X' to access at least one of their own content by touching the 'Allow access to my content' button (522) shown in the second action (520). In another embodiment, the user may request at least some of the other users (or user accounts) included in 'Chatroom X' to allow access to at least one of the multiple contents associated with the user by touching the 'Request access to content' button (524) shown in the second action (520).

[0083] FIG. 6 is a diagram illustrating an example of determining content to be accessed 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 user input selecting at least one content to be accessed among a plurality of contents associated with a first user account. In response to such user input, the processor may determine at least one content to be accessed among a plurality of contents associated with the first user account. Accordingly, the processor may allow a second user account included in a first chat room to access the determined at least one 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 the storage space of the first user account (e.g., cloud storage space, external storage device, etc.) and / or content associated with a chat room containing the first user account.

[0084] In one embodiment, at least one piece of content to be accessed may refer to the content item itself, such as a file item (612), a contact item (614), or a photo item (618) associated with the first user account, the storage space (616) of the first user account itself, and / or each chat room (620, 622, 624) containing the first user account itself. For example, as the file item (612), contact item (614), photo item (618), etc. are each selected, the content to be accessed may refer to content stored on 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, 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 described, the processor may display on the display buttons associated with each of the following contents associated with the first user account: 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). Then, in response to receiving user input (e.g., touch input, etc.) for some of the buttons displayed on the display (e.g., a button associated with the photo item (618)), the processor may determine that the item (e.g., the photo item (618)) is at least one of the contents to be accessed. Accordingly, the processor may allow the second user account to access all of the contents included in the first user's photo item (618).

[0085] The processor may determine an access permission period (628) for at least one determined content. For example, the access permission period (628) may include a period such as one hour, one day, one week, one month, and / or an end date (or start date) corresponding to a specific point in time such as '2021.01.22'. In one embodiment, the processor may receive user input to set the access permission period (628) and, in response, determine an access permission period (628) for at least one content. For example, the first user account may set the access permission period (628) for the content by directly inputting the access permission period (628) through an input device (e.g., text input). Alternatively, the first user account may set the access permission period (628) for the content by selecting at least one of the periods included in the list of access permission periods (628).

[0086] When an access permission period (628) for content is set, the processor may allow a second user account to access at least one piece of content only if the current time (e.g., the current time of the user terminal) falls within the access permission period (628). For example, depending on user input (e.g., touch input, etc.) of a first user account that sets the access permission period (628) to '1 Hour', the access permission period (628) may be determined to be '1 Hour' as illustrated. In this case, the second user account may be allowed to access at least one piece of content for one hour from the start time of access permission.

[0087] In FIG. 6, when the first user account allows access to content (e.g., immediately before or immediately after allowing access), at least one content and an access permission period (628) to be accessed are selected, thereby determining at least one content and an access permission period (628) to be accessed by the second user account, but are not limited thereto. For example, at least one content and / or an access permission period to be accessed may be determined based on information regarding the content (i.e., the content to be accessed) and / or the access permission period selected by the second user account when requesting access to content (i.e., a request indicating that access is to be allowed).

[0088] FIG. 7 is a diagram illustrating an example of determining content to be accessed according to an embodiment of the present disclosure. In one embodiment, at least one piece of content to be accessed may refer to each individual piece of content included in an item of content, each individual piece of content included in a chat room including a first user account, and each individual piece of content included in a storage space of a first user account. For example, as the first user account selects a button for a photo item among the buttons for items of content (or chat rooms, storage spaces) displayed on the display, a processor (e.g., at least one processor of a user terminal) may output a plurality of images stored in the user terminal on the display. Subsequently, as illustrated, as the first user account selects at least some (712) of the plurality of images (e.g., touch input, drag input, etc.), the processor may allow a second user account to access the selected at least some of the images (712).

[0089] In one embodiment, the processor may output a range of recommended content through the first chat room of the first user account based on an analysis result of at least one of the content associated with the first user account or the 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 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 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., for the analysis of at least one of the content associated with the first user account or the text included in the first chat room. Subsequently, the processor may determine at least one content to be accessed by receiving a user input (e.g., touch input, drag input, etc.) for selecting at least one content from the output range of recommended content.

[0090] For example, the processor may determine, among a plurality of images stored on the user terminal of the first user account, an image containing (or captured) at least some of the user accounts included in the first chat room as the range of recommended content, and output the range of recommended content through the first chat room of the first user account. To this end, the information processing system may determine, based on the person analysis results included in each of the plurality of images, an image containing (or captured) at least some of the user accounts included in the first chat room as the range of recommended content, and provide the determined range of recommended content through the first chat room of the first user account.

[0091] As another example, the processor may determine the scope of recommended content to include a file item associated with the first user account (or a document containing the text 'assignment' stored on a user terminal, etc.) based on the analysis result of the text 'assignment' included in the first chat room, and output the scope of recommended content through the first chat room of the first user account. To this end, the information processing system may determine the scope of recommended content to include a file item associated with the first user account (or a document containing the text 'assignment' stored on a user terminal, etc.) based on the analysis result of the text included in the first chat room, and provide the determined scope of recommended content through the first chat room of the first user account.

[0092] FIG. 8 is a diagram illustrating an example in which an access permission request is received from another user account according to one 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 for content associated with a first user account. Accordingly, the processor may output a message (812) regarding the access permission request received through a first chat room of the first user account. In response to the output message (812), the processor may receive user input allowing access to content associated with the first user account.

[0093] An access permission request received from a second user account may include information regarding the content for which access is requested by the second user account. Based on the information regarding the content for which access is requested, the processor may determine at least one content to be allowed among a plurality of contents associated with the first user account. That is, the second user account may select the content to request access to from among the plurality of contents associated with the first user account and transmit an access permission request for the selected content to the second user account. Subsequently, if the first user account allows access by the second user account, the processor may allow access to the content selected by the second user account. Alternatively, the first user account may re-select at least one content to be allowed access and allow access by the second user account. In this case, the processor may allow the second user account to access only the re-selected at least one content.

[0094] As illustrated in the first operation (810), upon receiving a request from 'USER A' to allow access to the user's document file, the processor may output a message (812) through 'Chatroom X' stating, 'USER A requests permission to access the document file.' The message (812) may include a 'View Details' button (814), an 'Accept Access' button (816), and a 'Deny Access' button (818). If the user touches the 'Accept Access' button (816) included in the message (812), the processor may allow 'USER A' to access the user's document file. Additionally, if access permission conditions and / or access permission information, such as the content to be accessed, the access permission period, and the user to be accessed, are modified before or after the user touches the 'Accept Access' button (816) included in the message (812), the processor may allow USER A access 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 may not allow 'USER A' access to the user's document file. Additionally, if the user touches the 'View Details' button (814) included in the message (812), the processor may output detailed information regarding 'USER A's' access permission request, such as information about the content for which access is requested and the requested access permission period.

[0095] In one embodiment, the processor may output a message (822) indicating that the second user account is accessing at least one determined content through the first chat 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 content associated with the first user account in real time through the first chat room of the first user account (e.g., content is being output to the user terminal of the second user account or content is being downloaded). Alternatively or additionally, the processor may output a message indicating that the second user account is in a state where it can access at least one content associated with the first user account (i.e., access is allowed).

[0096] As illustrated in the second operation (820), the processor may output a message (822) through 'Chatroom X' stating, 'USER A access to the document file is allowed.' Through this message (822), the user can recognize that 'USER A' is able to access their document file. The message (822) may include a 'View Details' button (824) and a 'Restrict Access' button (826). For example, if the user touches the 'View Details' button (824), the processor may output detailed information such as the content (or range of content) that is allowed access, the content that 'USER A' is accessing in real time, and the access permission period. Additionally, the processor may receive user input to block access to at least one piece of content, and based on this user input, access by the second user account to at least one piece of content may be blocked. For example, if the user touches the 'Restrict Access' button (826), the processor can block 'USER A's' access to the document file.

[0097] FIG. 8 illustrates an example in which one of the multiple user accounts included in a chat room is allowed to access at least one piece of content, but is not limited thereto. For example, all or some of the multiple user accounts included in a chat room may be allowed to access at least one piece of content.

[0098] FIG. 9 is a diagram illustrating an example in which a message (914) regarding whether access is allowed is output based on the result of analyzing 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 access to content associated with a first user account is allowed through a first chat room of a first user account, based on the result of analyzing text (912) included in a first chat room. To this end, an information processing system and / or processor may generate an analysis result for text (912) included in a first chat room and, based on the generated analysis result, transmit a message (914) regarding whether access to content associated with a first user account is allowed through a first chat room of a first user account. In this case, at least one content to be accessed and / or the access permission period may be automatically determined based on the analysis result. For example, the processor may determine, based on the analysis result of the text "Yeosu travel photos" among the texts included in the chat room of the first user account, an image containing location information corresponding to "Yeosu" as at least one piece of content to be allowed access. Alternatively, the at least one piece of content to be allowed access and / or the access permission period may be automatically determined as a default value.

[0099] As described above, based on the analysis result of the text (912) of ‘USER A’ included in ‘Chatroom X’ that says ‘I want to see the photo taken yesterday’, the processor may output a message (‘Would you allow USER A’s access to the image taken (or saved) on yesterday’s date (e.g., ‘2021.01.01’) among the multiple images included in the user terminal (‘Would you allow USER A’s access to the image from 2021.01.01?’) (914). To do this, the information processing system and / or processor may generate a text analysis result of the text included in ‘Chatroom X’ that says ‘yesterday’, ‘photo’, and / or ‘want to see’, and based on the generated analysis result, transmit a message (914) regarding whether to allow USER A’s access to the image taken (or saved) on yesterday’s date among the multiple images through the user’s ‘Chatroom X’. In other words, even if 'USER A' does not directly perform a separate task for the access permission request, the access permission request can be executed by automatically recognizing 'USER A's' intent through text analysis, etc.

[0100] Subsequently, depending on the response of the first user account to the message (914), the processor may determine whether to allow the second user account access to the content associated with the first user account. For example, the processor may receive user input allowing access to the content associated with the first user account in response to the output message (914) regarding access permission. As illustrated, the message (914) regarding access permission may include a 'View Details' button (916), an 'Accept Access' button (918), and a 'Deny Access' button (920). For example, if the user touches the 'Accept Access' button (918), the processor may allow 'USER A' access to an image taken on 2021.01.01 stored on the user terminal. On the other hand, if the user touches the 'Access Denied' button (920), the processor may not allow 'USER A' access to the image taken on 2021.01.01 stored on the user terminal. Additionally, if the user touches the 'View Details' button (916), the processor may output detailed information such as information about the content associated with access permission and the deadline.

[0101] FIG. 10 is a diagram illustrating an example in which a message (1012) regarding whether access to content associated with a chat room is allowed and a message (1022) indicating that access to content associated with a chat room is being accessed are output according to an embodiment of the present disclosure. At least one piece of content to be allowed access may include content associated with a second chat room (e.g., 'Chatroom Y') that includes a first user account (e.g., 'USER B') and does not include 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 containing the first user account through the first chat room (e.g., a chat room containing the first user account and the second user account). 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 included in the second chat room (i.e., conversation content), content associated with the user account included in the second chat room, etc. In one embodiment, to allow access to content associated with the second chat room by the second user account, a message (1012) regarding whether to allow access to content associated with the second chat room (e.g., all or part of the content within the chat room) may be sent to a third user account included in the second chat room. Here, the third user account may include one or more user accounts included in the second chat room.

[0102] In one embodiment, a processor (e.g., at least one processor of a user terminal) may allow a second user account to access content associated with a second chat room based on an access permission request from a third user account (i.e., a request indicating an intention to allow access). Conversely, the processor may block the second user account's access to content associated with the second chat room based on an access blocking request from the third user account. For example, if all of the plurality of third user accounts allow access to the second user account, the processor may allow the second user account to access content associated with the second chat room. Alternatively, if a majority of the plurality of third user accounts allow access to the second user account, the processor may allow the second user account to access content associated with the second chat room. Thus, the second user account may be allowed to access content associated with the second chat room when permission is granted by the third user account as well as the first user account.

[0103] To this end, an information processing system (e.g., at least one processor of the information processing system) transmits a message regarding whether to allow access to content associated with the second chat room to a third user account included in the second chat room, receives a response regarding whether to allow access (e.g., a request to allow access or a request to block access) from the third user account, and based on the received response from the third user account, may provide a connection link through the first chat room of the second user account that enables the second user account to access the content associated with the second chat room.

[0104] As illustrated in the 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 to allow access to content associated with 'Chatroom Y', the user terminal of said user account may output a message (1012) through 'Chatroom Y' stating, "USER A requests permission to access Chat Y." The message (1012) may include a "View Details" button, an "Accept Access" button (1014), and a "Deny Access" button (1016). For example, if all user accounts included in 'Chatroom Y' select the "Accept Access" button (1014), access by "USER A" to content associated with 'Chatroom Y' may be allowed. On the other hand, if some of the user accounts included in 'Chatroom Y' select the 'deny access' button (1016), access to content associated with 'Chatroom Y' by 'USER A' may not be allowed.

[0105] In one embodiment, a message (1022) indicating that the second user account is accessing content associated with the second chat room may be output through the second chat room of the first user account and / or the third user account. As illustrated in the second operation (1020), a message (1022) stating "USER A's access to Chat Y is allowed" may be output through the 'Chatroom Y' of the user account included in 'Chatroom Y'. Through this message (1022), the user account included in 'Chatroom Y' may recognize that 'USER A' is in a state where they can access content associated with 'Chatroom Y'. The message (1022) may include a 'View Details' button and a 'Restrict Access' button (1024). If some of the user accounts included in 'Chatroom Y' select the 'Restrict access' button (1024), access by 'USER A' to content associated with 'Chatroom Y' may be blocked.
