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 the embodiment of the present invention does not have to include all of the above components at the same time, and some of the above components may be omitted according to each embodiment, and the processor 210 is Some or all of the constituent parts of may be selectively 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 on a file to be shared and information on a person to be shared with the file designated by the file sharer terminal 120a. That is, the file sharing request information may include information on which files are to be shared with whom, and may be a signal for requesting creation of a chat room for file sharing.

Therefore, 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 generation unit 320 and the control unit 330.

The chat room generation unit 320 may create a file sharing chat room. To which file the corresponding file sharing chat room is associated with a chat room, and who is a participant in the chat room may be designated by the file sharing request information described above. The chat room creation unit 320 is associated with the file to be shared, and is associated with the file to be shared according to information that can identify the file to be shared and the person to be shared in the file sharing request information provided by the file sharing request receiving unit 310 You can create a file sharing chat room in which you 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 file to be shared through the corresponding file sharing chat room.

As a file-sharing chat room for a specific file is opened, the file sharer and the file-sharing target participate as chat participants in the file-sharing chat room to share the file to be shared through the file-sharing chat room. In particular, even if the file to be shared is a file to which the file to be shared has not previously been granted access rights, the file to be shared is provided through a file sharing chat room, thereby obtaining limited access rights to the file to be shared. And the file to be shared can be shared with the file sharer.

There may be various embodiments of a method for the control unit 330 to provide 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 a chat room, the chat room-based file sharing device 110 transmits the file to be shared to the file sharing target terminal 120b. Can be transmitted. In addition, in the file sharing chat room, an access path to a corresponding file to be shared may be provided as one of the chat messages.

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

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

That is, the controller 330 may provide a file object corresponding to the file to be shared in the form of a conversation 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 file to be shared 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 control unit 330 may transmit an access path to the file to be shared through the corresponding 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 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. In addition, the file to be shared 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 a memory in the file sharing target terminal 120b.

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

That is, according to an embodiment of the present invention, the control unit 330 allows the file to be shared to be shared with a plurality of users, but provides the file to be shared to the person to be shared with the file-sharing subject in a state of restricting authority to the file.

The difference between file sharing through e-mail or general messenger and the present invention is that by restricting permanent storage of the file to be shared, the rights of the file-sharing target for file retention, modification, and deletion beyond the control of the file sharer are limited. will be. This distinction is also meaningful in that it can prevent the copying or redistribution of files to be shared that require security maintenance.

Meanwhile, the file to be shared may be a file that is also shared by other users excluding the file sharer and the file share target. In particular, it may be assumed that the file to be shared is a file located in a specific shared folder, and other users participate as folder participants in the shared folder. 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 person to whom the file is to be shared. In addition, according to an embodiment, update details due to modification or change of a file to be shared by a folder participant may be reflected in real time in a file sharing chat room.

Here, the update of a file may be an example of an update that occurs in a file in which all changes that have occurred in relation to a file, such as when a file is newly created, modified, changed, or edited, or an access right to a file is changed. The update details of the file indicate specific contents that have changed as the file is updated.

That is, when a file to be shared is modified by a third party other than a participant in the conversation, including a folder participant in the shared folder, an update history including at least one of modification and change occurs in the file to be shared. In this case, the controller 330 may provide a new file object corresponding to the updated file to be shared 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 a file to be shared 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 a file sharing chat room.

When a file to be shared is updated, the control unit 330 records information about the file update through a file sharing chat room, by recording when and with what content the update was generated through a user's terminal, that is, the corresponding sharing. Information on the subject of the update and the time of the update, along with the update history of the target file can be provided.

In addition, when a chat message is not input through the file sharing chat room for a certain period of time or longer or the file to be shared is not updated, the control unit 330 is the target of the latest version of the last version updated by the chat participant terminal 120a or 120b. The file object of the file may be stored in the memory 220. In addition, the controller 330 may delete the file objects of the previous version of the file to be shared in the old order. Alternatively, if the control unit 330 selects a file to be deleted first, the memory 220 may delete the corresponding file or move it to a separate storage space.

In addition, when the file to be shared is modified by a third party other than the participant in the conversation, the control unit 330 provides the update details according to the modification or change of the file to be shared 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.

In addition, as illustrated above, the third party except for the conversation participant who updated the file to be shared may be at least some of the folder participants of the shared folder where the file to be shared was originally located. And the file sharer may be at least one of the folder participants.

In this case, the shared folder where the file to be shared was 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 differences in the path or authority to access the file to be shared.

The 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 a folder participant. In this case, the conversation participant, that is, the file sharer and the file sharing target can access the file to be shared through the file sharing chat room materialized in their respective terminals. And folder participants can access the files to be shared through the shared folder, that is, the original folder.

Accordingly, the file sharer, who is a folder participant, can access the file to be shared through both the file sharing chat room and the shared folder. In addition, 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, and to the file to be shared through the shared folder. File sharing targets who are not folder participants can access the files to be shared only through the file sharing chat room, and folder participants who are not participants of the conversation can access the files to be shared only through the shared folder, which is the original folder.

If the file sharer is not a folder-sharing member of the original folder, that is, a folder participant, for example, if the file sharer has also shared the target file from another user, especially the file to be shared along with a personal folder for file sharing. This can be illustrated as a case where the user receives the shared file and has the right to re-share the file to be shared.

If a personal folder for file sharing is provided to the person to whom the file is shared, the person to whom the file is shared, not the folder participant of the shared folder, which is the original folder, can access the file to be shared through the file sharing chat room and the personal folder for file sharing. .

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

The control unit 330 may grant a conversation participant permission to one or more of viewing or modifying a file to be shared, and may grant a folder participant permission to one or more of viewing, modifying, and deleting a file to be shared. . That is, when a file to be shared is shared through a file sharing chat room, the person to whom the file is shared may not be given permission to delete the file to be shared. In other words, whether or not to delete the file to be shared through the file sharing chat room can be decided by the folder participants of the original folder or the file sharer. In particular, when a corresponding file to be shared is deleted from a shared folder, which is an original folder, a file to be shared and/or a file to be shared provided for sharing through 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 a conversation message or an update history of a file to be shared is newly generated, the controller 330 is a conversation participant terminal (120a and/or 120b) or a terminal of a folder participant having permission to access the corresponding shared file. You can send a notification message to. 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 person to whom the file is to be shared, if necessary. In the above-described embodiment, a case where a file request signal is input from the file sharing target terminal 120b has been described. That is, an embodiment in which the chat room-based file sharing device 110 transmits the corresponding file to be shared to the file sharing target terminal 120b, and the corresponding file to be shared is accessed through the chat room and materialized as described above.

In contrast, in 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 a file sharing target person, and the file sharing target person terminal 120b The case of accessing the file to be shared through this personal folder will be described.

For example, when a file to be shared is provided to the file sharing target terminal 120b through a folder, the folder management unit 340 creates a file sharing personal folder dedicated to the file sharing target person, and stores the file to be shared through the corresponding personal folder. It can be provided to the sharing 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 file to be shared is included in the personal folder, and the file sharing target terminal 120b is in the corresponding personal folder. You have access rights, and you can access the files to be shared through the corresponding personal folder. In this case, the file to be shared provided to the file sharing target terminal 120b may be located in a personal folder for file sharing.

In the case where the file sharing target terminal 120b accesses the corresponding personal folder again later, the folder management unit 340 or the control unit 330 checks whether or not the file sharing target terminal 120b has access rights. As a result of the verification, only when access rights to the corresponding personal folder are confirmed, a list of files to which the file sharing target terminal 120b has access rights among files to be shared in the corresponding personal folder may be provided.

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 rights 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 determined that the corresponding file sharing target person or the file sharing target person terminal 120b has permission to access the corresponding personal folder.

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

In addition, as described above, the 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 has been provided with a personal folder for file sharing may access the file to be shared through the corresponding personal folder or the file to be shared through a file sharing chat room. However, in the personal folder, not only the corresponding file sharing chat room, but also other files shared to the person to whom the file is shared through other chat rooms may be located together. When a personal folder for file sharing is not provided, the access path may be restricted so that the file sharing target terminal 120b can access the corresponding file to be shared only through a file sharing chat room.

In addition, here, the permission for the viewing and updating of the file-sharing target for the file to be shared may be set in advance. For example, a person to whom the file is shared may be able to view the file to be shared but cannot modify it, or it may be set to allow both view and modification. When the terminal 120b of the file sharing target accesses the file to be shared, the file to be shared may be opened only when the permission of the file sharing target is confirmed according to a preset setting, and displayed on the terminal 120b of the file sharing target or , It 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 above-described personal folder or file sharing chat room.

If the file to be shared is modified or changed by the file sharing target terminal 120b, a new file object updated and other update details 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 updated details and the updated new file object may also be stored in the personal folder. Alternatively, in the case of a file to be shared provided through a chat room, update details and an updated new version of the file object may be recorded in the chat room. In this case, the update details 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 updated details and the updated new version of the file object will be stored in the memory 220 of the chat room-based file sharing device 110. I can.

As described above, it may be limited to store the 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 view and update the file to be shared follows according to the pre-set. Here, the terminal 120b of the file sharing target may update the opened file to be shared through the file sharing chat room only when the right to update, such as modification of the file sharing target, 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 corresponding file sharing chat room. Alternatively, when the file to be shared is subordinated to the file sharing chat room or provided through a separate window associated with the file sharing chat room, the chat participant may update the file to be shared through the window. In this case, the new version of the file to be shared and the update history of the file to be shared 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 file to be shared and the update history updated by the conversation participant may be stored in a 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 management unit 350 may generate a conversation message by receiving a signal input from a conversation 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 file to be shared or an update history of a file to be shared provided in the form of a chat message. The conversation message is a general conversation message input through the conversation window of the file sharing conversation room by the conversation participant terminals 120a and 120b. Text or image, voice, or 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 who and when a message of which content is input among conversation participants. To this end, identification information of the conversation participant terminal (the file sharer terminal 120a and/or the file share 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 the file to another user, that is, a file sharing target person 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 by the file sharer terminal 120a to share files. The file sharer terminal 120a and the file share target terminal 120b are user terminals connected to a chat room-based file sharing device by wired or wirelessly, 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 the file sharing, that is, information on the person to whom the file is to be shared, and information on the object of the file sharing, that is, which file. It contains information about the file to be shared, indicating whether you want to share the file.

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

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

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

Here, the provision of a file to be shared does not mean that the file sharing target terminal 120b receives and downloads the corresponding file to be shared, and permanently stores it in a 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 in the file sharing target terminal 120b may be limited. This is to prevent the file 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 transmission and sharing of files through e-mail or a general messenger.

Therefore, the file to be shared may be transmitted in a form of a chat message in a file sharing chat room. In this case, when the file-sharing target person modifies or changes the file to be shared, the file may be updated in the chat window of the file-sharing chat room. In addition, the updated details and the updated new version of the file to be shared may be recorded in the file sharing chat room and stored in the memory 220.

Alternatively, the file to be shared may be subordinated to the file sharing chat room or displayed through a separate window associated with it, and may be updated, modified or changed. Even in this case, the update details and the updated new version of the file to be shared may be recorded in the file sharing chat room and stored in the memory 220.

In addition, an access path to a file to be shared may be displayed in the file sharing chat room. The access path to the file to be shared may be displayed in the form of a chat message in the file sharing chat room, or may be fixedly displayed in a partial 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, an access path and access rights to a corresponding personal folder may be given to the file sharing target terminal 120b, and a file to be shared may be provided through the corresponding personal folder. As a method of providing a file to be shared through a personal folder, there may be a method of storing an access path to the file to be shared in a 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 may 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 a chat room-based file sharing system 100, a chat room-based file sharing device 110 and chat participant terminals 120a and 120b, that is, a file sharer terminal 120a and a file sharing target terminal ( The signal flow between 120b) will be described.

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 a file sharing target person or 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). Participants in the conversation in the file sharing chat room are the file sharer and the person to whom the file is shared. The file sharer and the file sharing target may each be at least one user, and one user may access using one or more terminals.

The chat room-based file sharing device 110 provides the generated 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 indicating that there is a file shared through the file sharing chat room and that there is a chat room invitation to the file sharing target terminal 120b (S530).

In addition, the file sharing chat room may be materialized in the file sharing target terminal 120b (S535). The file sharing target who 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 in order to check the file to be shared. Can be transmitted (S540). For example, the file sharing target may input a shared file request signal by clicking on 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 that is requested to provide the shared file may process the file to be shared according to a preset setting (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 insert it to update the dialog file object.

Alternatively, according to another embodiment, when the file to be shared is transmitted through a chat room, the file to be shared may be compressed into a transferable form, or the like. However, in such a processing process, the rights of the file sharing target for the corresponding file to be shared may be restricted. For example, the file to be shared may be set not to be permanently stored in the file sharing target terminal 120b. In addition, it may be set so that it can be viewed but not edited. The rights of the file sharing target for saving, deleting, viewing, and modifying files can be set in various ways. In addition, the file to be shared is dependent on or associated with the file sharing chat room, and may be set to be displayed only through a separate window designated in advance.

In addition, the chat room-based file sharing device 110 transmits and provides the file to be shared to the file sharing target terminal 120b, which has been processed according to a preset setting (S550).

Thereafter, the 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. In addition, when the file sharing target person has the right to modify the file to be shared, the target file may be modified on the file sharing target device terminal 120b (S560).

Then, the update details 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 file to be shared, updated together with the update details, may also be transmitted to the chat room-based file sharing device 110.

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

Accordingly, the file sharer terminal 120a may receive the update details of the file to be shared and/or the updated new version of the file to be shared by the person to be shared, and check the contents (S575). The file sharer who has confirmed the update of the file to be shared may provide feedback by inputting a chat message about this, and the corresponding chat message is transmitted to the chat room-based file sharing device 110 (S580). The chat room-based file sharing device adds a new chat message received from the file sharer terminal 120a to the message thread to update the chat file object again, and reflects the new chat message in the file sharing chat room (S585). In addition, the new chat 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 rights to the file to be shared. Try to explain the flow.

In FIG. 6, terminals other than the conversation participant terminals 120a and 120b having access rights to the files to be shared are the shared folder including the files to be shared and the folder participant terminals having access rights to files in the shared folder ( 120c). That is, the folder participant is not a folder sharing member of the shared folder, which is the original folder in which the file to be shared was included, 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. In addition, a file to be shared may be provided through the corresponding file sharing chat room (S630). At this time, the transmitted file to be shared is a file that has not yet been updated by the user, and is referred to as a file to be shared of version A (Ver.A) for convenience. Accordingly, the file sharer terminal 120b may materialize the file to be shared of version A (Ver.A) (SS635).

As described above, users other than the file sharer may also have access and modification rights to the file to be shared. In particular, an example may be a case where the original folder where the file to be shared is originally located is a shared folder in which two or more users participate. Accordingly, the folder participant terminal 120c of the shared folder, which is the original folder, may be a representative example of a user terminal having rights to access and modify a corresponding file to be shared without being a participant in the conversation.

In the embodiment described with reference to FIG. 6, the folder participant terminal 120c may access a file to be shared through a shared folder, which is an original folder, and may update the file to be shared. In addition, the update details 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.

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

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

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

The file sharing target who checks the file to be shared updated to version B may modify the target file to be shared again (S660). In this case, of course, it should be assumed that the file sharing target person or the file sharing target device terminal 120b has the right to modify the file to be shared. First, the file to be shared of version B is materialized on the file sharer terminal 120a and the file sharer terminal 120b, and the file to be shared of version B is modified on the file sharer terminal 120b, so that the file to be shared of version C It can be updated to (S660).

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

The chat room-based file sharing device 110 may store in the memory 220 a file to be shared, updated to version C, and update history from version B to version C, received from the file sharing target terminal 120b, This may be reflected in the file sharing chat room (S670). The updated details 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 viewed through a chat room (S675).

In addition, since the file to be shared 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, at the request of the folder participant terminal 120c, the folder participant The terminal 120c may receive the file to be shared updated to version C and the update details from version B to version C (S680).

As the file to be shared is updated, the file sharer terminal 120a may request the chat room-based file sharing device 110 to delete the oldest version of the file to be shared (S685). Of course, in another embodiment, when a predetermined condition is satisfied, such as a predetermined time elapsed or a predetermined number of updated files of a new version are accumulated, the controller 330 stores the old version of the file to be shared. You can also have them 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 file to be shared, which is stored in the memory 220. However, the file sharing chat room according to an embodiment of the present invention may be maintained as it is without being terminated or deactivated, assuming that files to be shared of version B and version C other than version A remain. If all versions of the file to be shared are deleted by a user who has permission to delete, the file sharing chat room may be terminated or disabled.

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 to the file sharing target terminal 120b, and to the file sharing target terminal 120b through the folder. You can provide the file to be shared. Here, the folder for file sharing may be a folder related to the 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 generate a file sharing chat room in response to the 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 file to be shared through a folder for file sharing (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 folder may be a personal folder of the file sharing target terminal 120b, or a shared folder to which the conversation participant terminals 120a and 120b jointly participate.

Here, the file sharing target terminal 120b may access the file to be shared through a folder for file sharing, and view and modify the file to be shared (S740). In this case, the file sharing target terminal 120b may access the file to be shared by accessing the file to be shared through the file sharing chat room, and may access the file to be shared through the folder to modify the file to be shared (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 file to be shared through the folder and view and modify the file to be shared.

When the file sharing target terminal 120b accesses the sharing target file through a folder for file sharing and modifies the sharing target file, the update details 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 a chat room for file sharing, the chat room-based file sharing device 110 does not need to create a folder, and the target to be shared through the file sharing chat room The file may be provided to the file sharing target terminal 120b. In addition, the file to be shared may be accessed and viewed by the person to be shared with the file through a chat room (S735).

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

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

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

In addition, the update of the file to be shared is reflected in the original folder where the file to be shared was originally located (S780), and the updated file to be shared may also be stored in the original folder. Therefore, even if a user who is not a participant in the chat has access and view rights to the file to be shared, the update history and the updated version of the file can be checked by the chat participant.

Although the above has been described with reference to preferred embodiments of the present invention, those skilled in the art will variously modify and change the present invention within the scope not departing from the spirit and scope of the present invention described in the following claims. You will understand that you can do it.
