3 is a block diagram of the processor 210 in the chat room-based file sharing device 110 according to an embodiment of the present invention.

According to the embodiment described with reference to FIG. 3 , the processor 210 includes a file sharing request processing unit 310 , a chat room generation unit 320 , a control unit 330 , a folder management unit 340 , and a message management unit 350 . can do. However, the processor 210 according to an embodiment of the present invention does not have to include all of the above components at the same time, and according to each embodiment, some of the above components may be omitted, and the processor 210 is Some or all of the constituent parts of may be optionally included.

The file sharing request processing unit 310 may receive file sharing request information from the file sharer terminal 120a. The file sharing request information includes information about a file to be shared and information about a target to share the file designated by the file sharer terminal 120a. That is, the file sharing request information may include information on which file to share with whom, and may be a signal for requesting creation of a chat room for file sharing.

Accordingly, when the file sharing request processing unit 310 receives the file sharing request information from the file sharer terminal 120a, the identification information of the file to be shared and the identification information of the file sharing target or the file sharing target terminal 120b from the file sharing request information may be extracted and provided to the chat room creation unit 320 and the control unit 330 .

The chat room creation unit 320 may create a file sharing chat room. Which file the corresponding file sharing chat room is associated with and who are the chat participants of the corresponding chat room may be designated by the file sharing request information described above. The chat room generating unit 320 is associated with the sharing target file according to the information capable of identifying the sharing target file and the file sharing target in the file sharing request information provided by the file sharing request receiving unit 310, and the file sharing target You can create a file sharing chat room where you can participate.

In addition, when the file sharing chat room is materialized in the file sharing target terminal 120b, the controller 330 may provide a file object corresponding to the sharing target file through the file sharing chat room.

As a file sharing chat room for a specific file is opened, the file sharer and the file sharing target share the file to be shared through the file sharing chat room by participating as conversation participants in the file sharing chat room. In particular, even if the target file to be shared is a file that does not have access rights in the past, by receiving the file sharing target file through the file sharing chat room, the file sharing target acquires limited access rights to the file sharing target file. Then, the file to be shared can be shared with the file sharer.

There may be various embodiments of a method in which the controller 330 provides a file to be shared to the file sharing target terminal 120b.

According to an embodiment, when a request signal for file provision is first received from the file sharing target terminal 120b through the chat room, the chat room-based file sharing device 110 sends the file sharing target file to the file sharing target terminal 120b. can be transmitted In addition, in the file sharing chat room, an access path to the corresponding shared target file may be provided as one of the chat messages.

For example, when the file sharing target clicks the chat room name of the file sharing chat room displayed on the file sharing target terminal 120b, the control unit 330 recognizes this as a request signal for requesting the provision of the sharing target file and the file sharing target file may be provided to the file sharing target terminal 120b through the file sharing chat room.

And in this case, when the sharing target file is transmitted to the file sharing target terminal 120b through the file sharing chat room, there may be various embodiments as to how the sharing target file is materialized in the file sharing target terminal 120b. First, the file to be shared may be provided in the form of a chat message in the file sharing chat room materialized in the file sharing target terminal 120b. In addition, an access path to the corresponding shared target file may also be provided in the form of a chat message in the file sharing chat room.

That is, the controller 330 may provide a file object corresponding to the sharing target file in the form of a chat message. When the file sharing chat room is materialized in the file sharing target terminal 120b, the controller 330 may transmit a file object corresponding to the sharing target file as one of the chat messages in the file sharing chat room through the file sharing chat room.

In addition, when the file sharing chat room is materialized in the file sharing target terminal 120b, the controller 330 may transmit an access path to the sharing target file through the file sharing chat room as one of the chat messages in the file sharing chat room.

In this case, the file to be shared may be displayed as a chat message in the chat window of the file sharing chat room, or may be displayed through a separate window subordinate to the file sharing chat room.

The sharing target file provided to the file sharing target terminal 120b through the file sharing chat room may be set to be temporarily stored in the memory 220 in the file sharing target terminal 120b. And the file sharing target file provided to the file sharing target terminal 120b through the file sharing chat room may be set to be impossible to be permanently stored in the memory in the file sharing target terminal 120b.

In this case, for example, when the file sharing chat room is terminated, the window in which the file to be shared is displayed may also be terminated or deactivated.

That is, according to the embodiment of the present invention, the control unit 330 allows the sharing target file to be shared with a plurality of users, but the file sharing target file can be provided to the file sharing target file in a state in which the authority for the file is limited.

The difference between file sharing through e-mail or general messenger and the present invention is that by limiting the permanent storage of the file to be shared in this way, it restricts the right of the person to share the file with respect to holding, modifying, or deleting the file that is out of the control of the file sharer. will be. This distinction is also meaningful in that it can prevent duplication or redistribution of shared files that require security.

Meanwhile, the sharing target file may be a file shared by the file sharer and other users other than the file sharing target. In particular, it may be assumed that the shared target file is a file located in a specific shared folder, and other users participate in the shared folder as folder participants. In this case, the file sharing target is not included in the folder participants of the shared folder.

In this case, the file to be shared may be modified and changed by users other than the file sharer and the file share target. And, according to an embodiment, the update history due to the modification or change of the sharing target file by the folder participant may be reflected in the file sharing chat room in real time.

Here, the update of a file may be an example of an update in which all changes occurring in relation to a file, such as when a file is newly created, modified, changed, or edited, or when access rights to the file are changed, occur in the file. The update history of the file indicates specific content changed as the file is updated.

That is, when a shared target file is modified by a third party other than a conversation participant, including a folder participant in the shared folder, an update history including at least one of modification and change occurs in the shared target file. In this case, the controller 330 may provide a new file object corresponding to the updated sharing target file through the file sharing chat room. Here, the new file object may be provided to the chat room in the form of a chat message. That is, when the sharing target file is modified by a third party other than the conversation participant, the controller 330 may provide it to the conversation participant terminals 120a and 120b in real time through the file sharing chat room.

When the file to be shared is updated, the control unit 330 records together when and through which user's terminal the update details were generated, and information about the update of the file through the file sharing chat room, that is, the corresponding sharing It is possible to provide information on the subject of the update, the update time, and the like along with the update history of the target file.

In addition, when a conversation message is not input through the file sharing chat room for a certain period of time or more, or the share target file is not updated, the control unit 330 controls the last version of the share target updated most recently by the conversation participant terminal 120a or 120b. A file object of a file may be stored in the memory 220 . In addition, the controller 330 may delete the file objects of the previous version of the shared target file in the order of the oldest. Alternatively, when the controller 330 selects a file to be deleted first, the memory 220 may delete the file or move the file to a separate storage space.

In addition, when the sharing target file is modified by a third party other than the conversation participant, the control unit 330 provides the update details according to the modification or change of the sharing target file to the conversation participant terminals 120a and 120b through the file sharing chat room. You may. In this case, the controller 330 may provide a new file object or update details according to the modified sharing target file as a chat message in the file sharing chat room through the file sharing chat room.

And, as exemplified above, a third party other than the conversation participant who updated the sharing target file may be at least some of the folder participants of the shared folder where the sharing target file was originally located. And the file sharer may be at least one of the folder participants.

In this case, the shared folder in which the file to be shared is originally located will be referred to as an original folder for convenience. In this case, the folder participant of the original folder, the file sharer, and the file sharing target have a difference in the path or authority to access the shared target file.

A file to be shared is located in a shared folder, that is, an original folder, and one or more users including a file sharer participate in the shared folder as folder participants. In this case, the conversation participants, that is, the file sharer and the file sharing target, can access the sharing target file through the file sharing chat room materialized in their respective terminals. And folder participants can access the shared target file through the shared folder, that is, the original folder.

Therefore, the file sharer who is a folder participant can access the shared target file through both the file sharing chat room and the shared folder. And, if the file sharer is not a folder participant, the file sharer is not allowed to access the shared folder, which is the original folder, or to the file to be shared through the shared folder. A file sharing target who is not a folder participant can access the file to be shared only through the file sharing chat room, and a folder participant who is not a conversation participant can access the shared file only through the shared folder, the original folder.

If the file sharer is not a folder sharing member of the shared folder that is the original folder, i.e., not a folder participant, for example, if the file sharer also receives the shared target file from another user, especially the shared target file together with the personal folder for file sharing It can be exemplified as a case in which the user has shared the file and has the re-sharing right for the file to be shared.

If a personal folder for file sharing is provided to a file sharing target, the file sharing target who is not a folder participant in the original shared folder can access the shared target file through the file sharing chat room and personal folder for file sharing. .

Between the conversation participant and the folder participant of the shared folder that is the original folder, and between the file sharer and the file share target, not only the access path to the shared target file but also various permissions for the shared target file may be differentially set.

The control unit 330 may grant the conversation participant the right to at least one of viewing and modifying the file to be shared, and grant the folder participant the right to at least one of viewing, modifying, and deleting the file to be shared. . That is, when a file to be shared is received through a file sharing chat room, the file sharing target may not be granted the right to delete the file to be shared. That is, whether or not to delete the shared target file shared through the file sharing chat room can be decided by the folder participants or the file sharer of the original folder. In particular, when the corresponding sharing target file is deleted from the shared folder that is the original folder, the sharing target file provided for sharing through the file sharing chat room and/or the corresponding file sharing chat room may be deleted or deactivated together.

In addition, when a new chat message is generated and accumulated in the file sharing chat room, the controller 330 may provide an alarm for this to the chat participant terminals 120a and/or 120b. When one or more of the conversation message or the update history of the sharing target file is newly generated, the control unit 330 is a conversation participant terminal 120a and/or 120b having access to the corresponding shared target file or a terminal of a folder participant to send a notification message. Alternatively, the notification message may be transmitted to the user terminal 120 through the network input/output unit 240 .

The folder management unit 340 may provide a folder to a file sharing target if necessary. In the embodiment described above, the case where there is an input of a file request signal from the file sharing target terminal 120b has been described. That is, the embodiment in which the chat room-based file sharing device 110 transmits the corresponding sharing target file to the file sharing target terminal 120b, and the corresponding sharing target file is accessed and materialized through the chat room has already been described.

On the contrary, through the embodiment described below, the chat room-based file sharing device 110, in particular, the folder management unit 340 provides a personal folder for file sharing to the file sharing target, and the file sharing target terminal 120b. Let us explain the case of accessing the shared target file through this personal folder.

For example, when the target file to be shared is provided to the file sharing target terminal 120b through the folder, the folder management unit 340 creates a personal folder for file sharing dedicated to the file sharing target, and stores the share target file through the personal folder. It can be provided to the share target terminal (120b).

That is, when the folder management unit 340 creates a personal folder for file sharing and provides it to the file sharing target terminal 120b, the sharing target file is included in the corresponding personal folder, and the file sharing target terminal 120b is stored in the corresponding personal folder. You will have access rights, and you can access the file to be shared through the corresponding personal folder. In this case, the sharing target file provided to the file sharing target terminal 120b may be located in a personal folder for file sharing.

And when the file sharing target terminal 120b accesses the personal folder again later, the folder management unit 340 or the control unit 330 checks whether the file sharing target terminal 120b has access rights. As a result of the check, only when the access right to the corresponding personal folder is confirmed, it is possible to provide a list of sharing target files to which the file sharing target terminal 120b has access right among the sharing target files in the corresponding personal folder.

Here, the folder management unit 340 may obtain user information associated with the file sharing target terminal 120b or identification information of the terminal, and check the access right of the file sharing target terminal 120b to the personal folder for file sharing. The folder management unit 310 may allow access only when it is confirmed that the file sharing target or the file sharing target terminal 120b has the right to access the corresponding personal folder.

Here, the sharing target file may be a file in a personal folder provided to the file sharer by the chat room-based file sharing device, or may be a shared file in a shared folder in which the file sharer is participating as a folder participant together with other users. In this case, the controller 330 and/or the folder manager 340 may create a copy of the sharing target file and store it in a personal folder provided to the file sharing target for file sharing.

In addition, as described above, the target file to be shared may be provided to the file sharing target terminal 120b through a file sharing chat room without a personal folder for file sharing.

The terminal of the file sharing target who is provided with the personal folder for file sharing may access the sharing target file through the corresponding personal folder, or may access the sharing target file through the file sharing chat room. However, in the personal folder, not only the file sharing chat room but also other files shared with the file sharing target through other chat rooms may be located together. When a personal folder for file sharing is not provided, the access path may be limited so that the file sharing target terminal 120b can access the corresponding sharing target file only through the file sharing chat room.

And here, the right for the file sharing target to view and update the file to be shared may be set in advance. For example, the file sharing target may be able to read the sharing target file, but may not be able to modify it, or may be set to enable both viewing and editing. When the file sharing target terminal 120b accesses the sharing target file, the sharing target file may be opened only when the file sharing target's authority is confirmed according to a preset bar, and the file sharing target terminal 120b is displayed or , may be updated in response to a user input of the file sharing target terminal 120b. Of course, the file to be shared may be opened through the aforementioned personal folder or file sharing chat room.

If the file sharing target file is modified or changed by the file sharing target terminal 120b, the update details and the updated new file object according to the modification or change may be stored. When a file to be shared is provided through a personal folder for file sharing, the update history and updated new file object may also be stored in the personal folder. Alternatively, in the case of a shared target file provided through a chat room, the update history and the updated new version of the file object may be recorded in the chat room. In this case, the update history and the updated new version of the file object may be transmitted through the chat room in the form of a chat message. In addition, in the case of a file provided through a chat room and opened through a separate window dependent on the chat room, the update history and the updated new version of the file object are stored in the memory 220 of the chat room-based file sharing device 110. can

As described above, it may be limited to store the shared target file shared through the file sharing chat room in the memory of the chat participant terminals 120a and 120b. In addition, the authority to read and update the shared target file follows according to the preset bar. Here, the terminal 120b of the file sharing target may update the shared target file opened through the file sharing chat room only when the right to update the sharing target file such as modification of the file sharing target file is confirmed.

When the file to be shared is provided as one of the chat messages, the chat participant can update the file to be shared through the file sharing chat room. Alternatively, when the file to be shared is provided through a separate window that is dependent on or associated with the file sharing chat room, the conversation participant may update the file to be shared through the window. In this case, the new version of the sharing target file updated by the conversation participant and the update history of the sharing target file may be recorded in the file sharing chat room or stored in the memory 220 .

When the file to be shared is provided through the personal folder for file sharing described above, the conversation participant can access the file to be shared through the personal folder and open and update the file to be shared. In this case, the new version of the sharing target file updated by the conversation participant and the update history may be stored in the corresponding personal folder or may be stored in the memory 220 .

In addition, the processor 210 may further include a message management unit 350 . The message manager 350 may generate a chat message by receiving a signal input from the chat participant terminal (the file sharer terminal 120a and/or the file sharing target terminal 120b).

In addition, the message management unit 350 may create a chat file object including a message thread to be displayed through the file chat room. The message thread may include a chat message and a shared object file provided in the form of a chat message or an update history of the shared object file. The chat message is a general chat message input through the chat window of the file sharing chat room by the chat participant terminals 120a and 120b. A text or image, a voice or a file object may be input as a conversation message. Accordingly, the conversation message may have one or more types of file objects such as text, image, voice, or document.

When generating a conversation message, the message management unit 350 may generate a conversation message including all of the conversation participants who input the message when, when, and with what content. For this purpose, identification information of the conversation participant terminal (the file sharer terminal 120a and/or the file sharing target terminal 120b) may be used.

As the conversation message of the conversation participant terminal (the file sharer terminal 120a and/or the file sharing target terminal 120b) is continuously newly input in real time, the message management unit 350 also creates a new conversation message, and the control unit 330 can continue to update the file sharing chat room.

4 is a flowchart illustrating a chat room-based file sharing method according to an embodiment of the present invention.

The chat room-based file sharing device 110 receives file sharing request information from the file sharer terminal 120a (S410). The file sharer terminal 120a is a terminal of a user who shares a file with another user, ie, a file sharing target, through a chat room for file sharing based on the sharing authority for a specific file. The file-sharing target terminal 120b is a user designated to receive a file share by the file-sharing terminal 120a. The file sharer terminal 120a and the file sharing target terminal 120b are user terminals connected to a chat room-based file sharing device by wire or wireless, and may each include one or more user terminals.

The file sharing request information transmitted by the file sharer terminal 120a includes information on the subject of file sharing, that is, information on the file sharing target indicating with whom the file is to be shared, and information on the object of file sharing, that is, which file. It includes information about the file to be shared, indicating whether you want to share it.

In addition, the chat room-based file sharing device 110 creates a file sharing chat room associated with the sharing target file according to the file sharing request information ( S420 ). The chat room-based file sharing device 110 creates a file sharing chat room associated with a specified sharing target file according to the file sharing request information. And, the chat room-based file sharing device 110 designates a chat participant of the file sharing chat room, including the file sharer and the file sharing target designated by the file sharing request information.

In addition, the chat room-based file sharing device 110 may provide the file sharing chat room to the chat participant terminals 120a and 120b, and provide the file to be shared through the file sharing chat room (S430).

Here, the file sharing target terminal 120b may receive the sharing target file by inputting a sharing file request signal through the file sharing chat room. For example, when a chat room for file sharing is opened and the chat room is materialized, such as being displayed on the file sharing target terminal 120b, the file sharing target inputs a shared file request signal through the file sharing chat room on the file sharing target terminal 120b can do. An area for inputting a shared file request signal may be provided in advance on the user interface for the file sharing chat room. For example, when a button for inputting a shared file request signal is clicked or the title of the chat room is clicked, the chat room-based file sharing device 110 recognizes it as a shared file request signal according to a preset bar and sends it to the file sharing target terminal 120b. You can send and provide files to be shared.

Here, providing the file to be shared does not mean that the file sharing target terminal 120b receives and downloads the corresponding sharing target file and permanently stores the file in the memory area within the file sharing target terminal 120b. The file to be shared may be provided to the file sharing target terminal 120b to be materialized and displayed, and may be modified, changed, or updated according to the permission setting of the file sharing target. However, permanent storage in the memory within the file sharing target terminal 120b may be limited. This is to prevent files to be shared from being updated, retained, retransmitted, or distributed beyond the control of the file sharer. And due to this point, the embodiment of the present invention can be distinguished from the transmission and sharing of files through e-mail or a general messenger.

Accordingly, the file to be shared may be transmitted in the form of a chat message in the file sharing chat room. In this case, if the file sharing target modifies or changes the sharing target file, the updating of the file may also be performed in the chat window of the file sharing chat room. In addition, the update history and the updated new version of the shared target file may be recorded in the file sharing chat room and stored in the memory 220 .

Alternatively, the file to be shared may be displayed through a separate window subordinate to or related to the file sharing chat room, and may be updated, modified, changed, or the like. Even in this case, the update history and the updated new version of the shared target file may be recorded in the file sharing chat room and stored in the memory 220 .

In addition, an access path to a shared target file may be displayed in the file sharing chat room. The access path to the sharing target file may be displayed in the form of a chat message in the file sharing chat room, or may be fixedly displayed in some area of the file sharing chat room.

Alternatively, the file to be shared may be provided to the file sharing target terminal 120b through a folder created for file sharing, in particular, a virtual personal folder provided to the file sharing target. To this end, the chat room-based file sharing device 110 may create a personal folder dedicated to a file sharing target for file sharing. In addition, the file sharing target terminal 120b may be given an access path and access authority to the corresponding personal folder, and the file to be shared may be provided through the corresponding personal folder. As a method of providing the file to be shared through the personal folder, there may be a method of storing an access path to the file to be shared in the personal folder or a method of storing a copy of the file to be shared. And in this case, the personal folder for file sharing could be a kind of cloud.

5 is a diagram illustrating a chat room-based file sharing method according to another embodiment of the present invention.

5, on the chat room-based file sharing system 100, the chat room-based file sharing device 110 and the chat participant terminals 120a and 120b, that is, the file sharer terminal 120a and the file sharing target terminal ( 120b) to explain the signal flow between them.

First, the file sharer terminal 120a transmits file sharing request information to the chat room-based file sharing device 110 (S510). The file sharing request information may include identification information of a file to be shared and identification information of the file sharing target or the file sharing target terminal 120b.

The chat room-based file sharing device 110 creates a file sharing chat room according to the file sharing request information (S515). Conversation participants in the file sharing chat room are the file sharer and the file share target. Each of the file sharer and the file share target may be at least one or more users, and one user may connect using one or more terminals.

The chat room-based file sharing device 110 provides the created file sharing chat room to the file sharer terminal 120a and the file share target terminal 120b, respectively (S520 and S525). In addition, the chat room-based file sharing device 110 may transmit a notification signal notifying that there is a file shared through the file sharing chat room and there is an invitation to the chat room to the file sharing target terminal 120b ( S530 ).

And in the file sharing target terminal 120b, the file sharing chat room may be materialized (S535). The file sharing target who has accepted the invitation to the file sharing chat room and executed the file sharing chat room on the file sharing target terminal 120b sends a shared file request signal to the chat room-based file sharing device 110 to check the sharing target file It can be transmitted (S540). For example, the file sharing target may input a shared file request signal by clicking the title of the file sharing chat room materialized on the file sharing target terminal 120b or a specific area in the chat window.

As the shared file request signal is input, the chat room-based file sharing device 110 requested to provide the shared file may process the file to be shared according to a preset bar ( S545 ). That is, according to an embodiment, when the file to be shared is set to be provided as one of the chat messages, the chat room-based file sharing device generates the file to be shared as a chat message, and the file to be shared in the form of a chat message is newly added to the message thread. You can update the dialog file object by inserting it.

Alternatively, according to another embodiment, when the sharing target file itself is transmitted through a chat room, the sharing target file may be compressed into a transmittable form, and the like. However, in this processing process, the authority of the file sharing target for the corresponding sharing target file may be limited. For example, the sharing target file may be set not to be permanently stored in the file sharing target terminal 120b. In addition, it may be set so that viewing is possible but modification is not possible. The right of the file sharing target for saving, deleting, viewing, or modifying the file may be set in various ways. In addition, the file to be shared is dependent on or related to the file sharing chat room, and may be set to be displayed only through a predetermined separate window.

And, the chat room-based file sharing device 110 transmits and provides the shared target file processed according to a preset bar to the file sharing target terminal 120b (S550).

Thereafter, the target file to be shared may be materialized in the file sharing target terminal 120b (S555). For example, the file sharing chat room may be displayed through the display unit of the file sharing target terminal 120b. And when the file sharing target has the right to modify the file to be shared, the target file to be shared may be modified on the file sharing target terminal 120b (S560).

Then, the update history of the file to be shared may be transmitted to the chat room-based file sharing device 110 (S565). In this case, a new version of the shared target file updated together with the update history may also be transmitted to the chat room-based file sharing device 110 .

The chat room-based file sharing device 110 stores the update history by the file sharing target terminal 120b and a new version of the sharing target file according to the update history in the memory 220, and can be reflected in the file sharing chat room. (S570). That is, the update history and/or the updated new version of the shared target file is provided in the form of a chat message, or provided to be downloaded or viewed through a file sharing chat room.

Accordingly, the file sharer terminal 120a may receive the update history of the sharing target file and/or the updated new version of the sharing target file by the file sharing target, and check the contents (S575). The file sharer, who has confirmed the update of the file to be shared, can give feedback on this by inputting a chat message, and the chat message is transmitted to the chat room-based file sharing device 110 (S580). The chat room-based file sharing device updates the chat file object again by adding a new chat message received from the file sharer terminal 120a to the message thread, and reflects the new chat message in the file sharing chat room (S585). And a new conversation message may be transmitted to the file sharing target terminal (120b) (S590).

6 is a diagram illustrating a chat room-based file sharing method according to another embodiment of the present invention.

6, a signal between the chat room-based file sharing device 110 and the chat participant terminals (the file sharer terminal 120a and the file share target terminal 120b) and other terminals having access to the file to be shared to explain the flow.

In FIG. 6, terminals other than the conversation participant terminals 120a and 120b having access to the file to be shared have access to the shared folder including the file to be shared and the files in the shared folder. 120c). That is, the folder participant is a folder sharing member of the shared folder that is the original folder containing the file to be shared, but is not a conversation participant in the file sharing chat room according to the embodiment of the present invention.

First, the file sharer terminal 120a transmits file sharing request information to the chat room-based file sharing device 110 (S610). Accordingly, the chat room-based file sharing device 110 creates a file sharing chat room (S615). In addition, the chat room-based file sharing device 110 may transmit the file sharing chat room to the file sharer terminal 120a (S620), and the file sharer terminal 120a may materialize the file sharing chat room (S625).

The chat room-based file sharing device 110 may provide a file sharing chat room to the file sharing target terminal 120b as well. In addition, a file to be shared may be provided through the corresponding file sharing chat room (S630). The shared target file transmitted at this time is a file that has not yet been updated by the user, and is referred to as the sharing target file of version A (Ver.A) for convenience. Accordingly, the file sharer terminal 120b may materialize the file to be shared of the version A (Ver.A) (SS635).

As described above, users other than the file sharer may also have access to and modification rights to the file to be shared. In particular, the case where the original folder in which the file to be shared was originally located is a shared folder in which two or more users participate may be an example. Accordingly, the folder participant terminal 120c of the shared folder, which is the original folder, may be a representative example of a user terminal that is not a conversation participant but has rights such as access and modification to the corresponding shared target file.

In the embodiment described with reference to FIG. 6 , the folder participant terminal 120c may access the file to be shared through the shared folder that is the original folder and update the file to be shared. In addition, the update history generated outside the file sharing chat room by the folder participant terminal 120c may be reflected in the file sharing chat room in real time.

Also, in another embodiment, the original folder in which the sharing target file is located may be a personal folder of the file sharer. Even if the file sharer terminal 120a, which is one of the conversation participant terminals 120a and 120b, accesses the shared target file through the original folder, the personal folder or the shared folder, and updates the sharing target file, not through the file sharing chat room. The update history and the updated new version of the shared target file can be reflected in the file sharing chat room in real time.

The folder participant terminal 120c may access the sharing target file through the shared folder, which is the original folder, and modify the sharing target file of version A (Ver.A) to the sharing target file of version B (Ver.B) (S640). ). When the sharing target file is saved after modification, the sharing target file of version B (Ver.B) is transmitted to the chat room-based file sharing device 110 (S645).

And the updated sharing target of version B (Ver.B) is stored in the memory 220, and the update history of the sharing target file from version A to version B may be reflected in the file sharing chat room (S650). Therefore, the update history and the file to be shared of the updated version B may be recorded in the form of a chat message in the file sharing chat room, or provided to the chat participant terminals 120a and 120b through the file sharing chat room in a downloadable or viewable form ( S655).

The file sharing target who has checked the shared target file updated to version B may re-edit the corresponding shared target file (S660). In this case, of course, it must be assumed that the file sharing target or the file sharing target terminal 120b has the right to modify the sharing target file. First, the file sharing target file of version B is materialized on the file sharer terminal 120a and the file sharing target terminal 120b, and the file sharing target file of the version B is modified in the file sharing target terminal 120b, and the version C sharing target file may be updated (S660).

Accordingly, the second update history of the sharing target file from version B to version C may be transmitted from the file sharing target terminal 120b to the chat room-based file sharing device 110 (S665). A shared target file of the updated new version, that is, version C, may also be transmitted along with the update history.

The chat room-based file sharing device 110 may store the shared target file updated to version C and the update history from version B to version C in the memory 220 received from the file sharing target terminal 120b, This can be reflected in the file sharing chat room (S670). The update history and the file to be shared of the updated version C may be provided to the file sharer terminal 120a in the form of a chat message or a file that can be downloaded or read through a chat room (S675).

In addition, since the shared target file updated to version C and the update history from version B to version C are stored in the memory 220 and reflected in the shared folder, which is the original folder, upon request of the folder participant terminal 120c, the folder participant The terminal 120c may receive the shared target file updated to version C and the update history from version B to version C (S680).

As the sharing target file is updated, the file sharer terminal 120a may request the chat room-based file sharing device 110 to delete the sharing target file of version A, which is the oldest version (S685). Of course, in another embodiment, when a preset condition is satisfied, such as when a predetermined time elapses or a new version of the updated file accumulates more than a predetermined number, the control unit 330 stores the old version of the shared target file stored in the memory 220 You can also have it deleted.

In response to a deletion request from the file sharer terminal 120a, the chat room-based file sharing device 110 may delete the version A sharing target file stored in the memory 220 . However, a file sharing chat room according to an embodiment of the present invention may be maintained without being terminated or deactivated on the premise that, in addition to version A, files to be shared of version B and version C remain. If all versions of the shared target file are deleted by a user with the right to delete, the file sharing chat room may be terminated or deactivated.

7 is a diagram illustrating a chat room-based file sharing method according to another embodiment of the present invention.

In the embodiment described with reference to FIG. 7 , the chat room-based file sharing device 110 creates a folder for file sharing in the file sharing target terminal 120b, and sends the file to the file sharing target terminal 120b through the folder. You can provide a shared target file. Here, the folder for file sharing may be a folder associated with a chat room.

The chat room-based file sharing device 110 receives a file sharing request from the file sharer terminal 120a (S710). Transmission of file sharing request information is an example of a file sharing request. The chat room-based file sharing device 110 may create a file sharing chat room in response to a request and provide the file sharing chat room to the chat participants 120a and 120b (S720).

The chat room-based file sharing device 110 determines whether to share the sharing target file through a file sharing folder (S730). When a file to be shared is provided through a folder for file sharing, the chat room-based file sharing device 110 first creates a folder ( S740 ). The corresponding folder may be a personal folder of the file sharing target terminal 120b or a shared folder in which the conversation participant terminals 120a and 120b jointly participate.

Here, the file sharing target terminal 120b may access the sharing target file through a folder for file sharing, and view and modify the sharing target file (S740). In this case, the file sharing target terminal 120b may access the sharing target file through the file sharing chat room and modify the sharing target file, and may access the sharing target file through the corresponding folder and modify the sharing target file (S750) .

When a folder for file sharing is created as a shared folder in which conversation participants participate, not only the file sharing target but also the file sharers can access the shared target file and view and modify the shared target file through the folder.

When the file sharing target terminal 120b modifies the sharing target file by accessing the sharing target file through the file sharing folder, the update history and the updated new version of the sharing target file may be stored in the corresponding folder (S760). ).

If the chat room-based file sharing device 110 does not share a file through the chat room for file sharing, the chat room-based file sharing device 110 does not need to create a folder, and a sharing target through the file sharing chat room The file may be provided to the file sharing target terminal 120b. And the sharing target file can be accessed and viewed by the file sharing target through the chat room (S735)

When the file sharing target intends to modify the sharing target file, it is first determined whether the file sharing target or the file sharing target terminal 120b has update authority such as modification (S745). As a result, if it is determined that there is no right to edit, the chat room-based file sharing device 110 only provides the file to be shared for viewing (S735)

If the file sharing target has the authority to edit the file, the file sharing target can view and modify the shared target file through the file sharing chat room (S755).

The shared target file updated through the above-described process, such as correction or change, may be stored in a folder for file sharing or the memory 220 together with update details (S760). In addition, the chat room-based file sharing device 110 may reflect the update of the sharing target file in the file sharing chat room, and provide the update details and/or the updated sharing target file to the chat participant terminals 120a and 120b (S770). ).

Also, the update of the sharing target file is reflected in the original folder in which the corresponding sharing target file is originally located (S780), and the updated sharing target file may be stored in the original folder as well. Therefore, a user who is not a conversation participant can check the update history and the updated version of the file by the conversation participant if he/she has access and viewing rights to the file to be shared.

Although the above has been described with reference to preferred embodiments of the present invention, those skilled in the art can variously modify and change the present invention within the scope without departing from the spirit and scope of the present invention as set forth in the claims below. You will understand that it can be done.
