At this time, the processor 200 and components of the processor 200 may be implemented to execute instructions according to code of an operating system included in a memory and code of at least one program. Here, the components of the processor 200 may be expressions of different functions performed by the processor 200 according to a control command provided by the program code stored in the social media providing server 100.

The processor 200 may load program code stored in a file of a program for a method for providing social media into a memory. For example, when a program is executed in the social media providing server 100, the processor may control the social media providing server to load program code from a file of the program into a memory under the control of the operating system.

In step 310, the generator 210 may generate a chat room. The generation unit 210 may generate a chat room by inviting at least one user who wants to share the sharing information in the connected social media as identification information related to each user is input. At this time, a chat room may be opened in a messenger service that can share information between users.

In step 320, the first receiver 220 may receive that shared information is input from at least one user included in the chat room. The first receiver 220 may process the received sharing information and output the specific processed sharing information to a chat room. At this time, it is possible to blur the content of the shared information to make it difficult to read. In addition, it is possible to further process the process of displaying the presence or absence of the input shared information without outputting the content of the shared information. For example, sharing information including text data, images, and videos input from users invited to a chat room may be recognized as a message to conduct a conversation.

In step 330, the allocation unit 230 may allocate the divided pieces generated by dividing the received shared information based on the number of users included in the chat room to each user terminal included in the chat room. The allocation unit 230 may transmit the encrypted fragments obtained by encrypting the fragments using different encryption keys to each user terminal included in the chat room, and store the encrypted fragments in each user terminal. have.

In operation 340, the second reception unit 240 may receive a request for viewing the specific processed shared information from a specific user terminal included in the chat room.

In step 350, the restorer 250 may restore the specific shared information processed based on the divided pieces received from each user terminal included in the chat room. The restoration unit 250 requests to transmit the divided pieces allocated to each user terminal included in the chat room, when approval for viewing the specific processed shared information is accepted from each user terminal included in the chat room, and the chat room After receiving the encryption key corresponding to each user terminal together with the fragment pieces from each user terminal included in the decrypted fragment pieces, the specific shared information can be restored.

In step 360, the transmitting unit 260 may transmit the restored shared information to the user terminal requesting the viewing of the shared information. The transmission unit 260 may output the restored sharing information related to the sharing information in a chat room of the user terminal requesting the viewing of the sharing information.

4 is a diagram illustrating an example of a process of dividing shared information according to an embodiment.

In order to maintain the security of shared information transmitted and received between a plurality of users in social media, it will be described that the shared information is divided and stored. In order to be described in more detail, FIG. 4 will describe a process of dividing shared information transmitted and received between the first user terminal 110 and the second user terminal 111.

A chat room including the first user terminal 110 and the second user terminal 111 may be opened (410). The social media providing server 100 may automatically invite selected users to the chat room as at least one user is selected from the first user terminal 110, or, after the first user terminal creates the chat room, generates Users can be invited to the chat room. At this time, the chat room may include at least two or more users, and other users may be further added by users invited to the chat room later.

The first user terminal 110 may input sharing information in a chat room (420 ). At this time, the sharing information may exist in various ways, such as text data (for example, symbols, emoticons, numbers, characters, etc.), document files, images or videos, and may also include shooting data immediately photographed by a user. For example, when the first user terminal 110 loads a document file, image, video, voice data, etc. stored in the first user terminal 110, the loaded information may be uploaded to the chat room. In addition, the first user terminal 110 may upload the shared information generated in conjunction with functions such as shooting, recording, and document creation to a chat room.

The social media providing server 100 may receive the sharing information input from the first user terminal 110 (430 ). At this time, the social media providing server 100 may automatically delete the sharing information input from the first user terminal 110 as it receives the sharing information input from the first user terminal 110. For example, as the first user terminal 110 inputs a message including text data, the social media providing server 100 may output a message input from the first user terminal 110 in a chat room. At this time, the social media providing server 100 converts the message input from the first user terminal 110 to private after a preset time so that the content of the message input from the first user terminal 110 to each user terminal. It can be suppressed.

The social media providing server 100 may divide the sharing information input from the first user terminal 110 based on the number of users (N and N are natural numbers) included in the chat room (440). Alternatively, the social media providing server 100 may divide the sharing information based on the number of users (N-1, N is a natural number) excluding users who input a message among users included in the chat room. The social media providing server 100 may divide the sharing information into fragments of the same ratio or different ratios by identifying the first user terminal 110 and the second user terminal 110 included in the chat room. At this time, the social media providing server 100, after dividing the shared information, may be maintained by matching the information related to the division of the shared information as information necessary when restoring the divided shared information.

The social media providing server 100 may allocate the segmentation piece 1 to the first user terminal 110 and the segmentation segment 2 to the second user terminal 111 according to the division into the segmentation segment 1 and the segmentation segment 2. (450, 451). At this time, the divided pieces themselves are divided into forms that cannot be restored to the original shooting information.

The social media providing server 100 allocates each of the fragment pieces obtained by encrypting the fragment pieces using different encryption keys in the allocation of the fragment pieces, respectively, the first user terminal 110 and the second user terminal 111 ). At this time, the encryption key used for encryption may use the same encryption key or different encryption keys for each of the divided pieces, and transmits the encryption key used for the encryption of the divided pieces to each user terminal to divide the encryption key and the divided pieces. It can be saved together. Alternatively, the social media providing server 100 may store the encryption key on the server without transmitting it to the user terminal. Also, the encryption key used for the encryption of the fragmentation fragment may be stored in a different storage location from the fragmentation fragment.

The first user terminal 110 may store the divided piece 1, and the second user terminal may store the divided piece 2 (460, 470).

5 is a view for explaining an example of a process of restoring shared information according to an embodiment.

As described in FIG. 4, a process of restoring shared information transmitted and received between the first user terminal 110 and the second user terminal 111 included in the chat room will be described. From the first user terminal 110, viewing of shared information (for example, a message) transmitted and received in a chat room may be requested (510). At this time, the sharing information may be specific processed sharing information. For example, shared information may be blurred or private. The social media providing server 100 requests a user terminal (second user terminal) included in the chat room to view the specific processed sharing information by receiving a request to view the specific processed sharing information from the first user terminal 110 It may transmit a message related to (520). Approval for viewing the specific processed shared information from the second user terminal 111 may be accepted (530).

The social media providing server 100 receives the approval for the viewing of the specific processed shared information from the second user terminal 111, and the first user terminal 110 and the second user terminal 111, respectively. It may request to transmit the fragments stored in the terminal of the. The social media providing server 100 may receive the divided fragment 1 stored in the first user terminal from the first user terminal 110 and receive the divided fragment stored in the second user terminal from the second user terminal 111. (540, 541). On the other hand, if the second user terminal 111 does not accept the restoration of the specific processed sharing information, the social media providing server 100 cannot secure the fragment 2 for the requested sharing information to the original information. Since it is impossible to restore, it is possible to notify the first user terminal 110 of the inability to use the shared information. At this time, when the fragment fragment related to the shared information is encrypted, the social media providing server 100 may request transmission of an encryption key in the process of requesting the fragment fragment of the shared information. Accordingly, the fragmentation piece and the encryption key for the fragmentation piece can be received from the second user terminal to decrypt the fragmentation piece. Alternatively, when the encryption key is stored in the social media providing server 100, the encryption key for the fragment is read to decrypt the fragment.

The social media providing server 100 may restore the original shared information by using the divided fragment 1 and the divided fragment 2 (550) as both the fragment 1 and the fragment 2 are received. The social media providing server 100 may transmit the restored sharing information to the first user terminal 110 requesting the viewing of the sharing information (560). The restored shared information may be disclosed in the chat room of the first user terminal 110. At this time, when the social media providing server 100 transmits the restored sharing information to the first user terminal requesting the use of the sharing information, it copies the restored sharing information using a copy protection technique (eg, watermark technology, etc.) In the case of shared information containing contents that are intended to be protected between users, it is possible to restore and use the shared information only with the consent of each other.

The social media providing server according to an embodiment may divide the sharing information into pieces and store and share it in each user terminal included in the chat room, thereby confirming the sharing information with permission between users included in the chat room, If the other party does not allow, it is impossible to check and leak the shared information.

6 to 10 are examples for explaining a method for providing social media in a user terminal according to an embodiment.

Referring to FIG. 6, a diagram for explaining a process of executing social media in a user terminal. The user may select the user interface 630 for logging in after entering identification information related to the user in order to access social media through the user terminal 110. For example, as the ID (email address) and password are input as identification information related to the user, the social media providing server may perform user authentication by comparing the identification information stored in the social media providing server. In this case, the social media providing server may allow the user to access the social media if the user's identification information matches the stored identification information, and if the user's identification information does not match, the social media providing server is not permitted to access the social media. can do.

As an example, a process of subscribing to social media at the user terminal may be performed. At this time, when the user terminal joins the social media, an authentication server for processing user authentication, an OTP server for generating a password, and a social media providing server may be operated. The social media providing server may request a new OTP to the authentication server according to the subscription request of the user terminal, and the social media providing server may transmit a user ID for joining social media to the authentication server when requesting a new OTP. The authentication server may request a new OTP from the OTP server according to the new OTP request from the social media providing server. The OTP server may randomly generate OTP according to a new OTP request from the authentication server, and transmit the generated OTP to the authentication server. At this time, the OTP can be automatically generated freely without limitation on the length and whether special characters are included. The authentication server may store the OTP received from the OTP server in a database included in the authentication server or connected to the authentication server. The authentication server can generate two OTPs by storing the OTP received from the OTP server for the new OTP request from the social media providing server together with the user ID received from the social media providing server, and dividing the OTP received from the OTP server. have. For example, when the OTP received from the OTP server is {1234567890}, it can be divided into divided OTP 1{12345} and divided OTP2{67890}. The authentication server may transmit the divided OTP 1 and the divided OTP 2 to the social media providing server requesting the new OTP. The social media providing server may receive the divided OTP 1 and the divided OTP 2 from the authentication server, and store one of them in a database included in the social media providing server or connected to the social media providing server. At this time, the social media providing server may match the user ID and device information included in the subscription request of the user terminal with the divided OTP1 and store it in a database connected to the social media providing server. The social media providing server may transmit another one of the divided OTP 1 and the divided OTP 2 received from the authentication server, for example, the divided OTP 2 to the user terminal requested to join. The user terminal may store the divided OTP2 received from the social media providing server for the subscription request in a database included in the user terminal or connected to the user terminal. At this time, the user terminal may match the user ID input by the user and the device information of the user terminal with the divided OTP2 and store it in a database connected to the user terminal. The user terminal may complete the subscription procedure by receiving a portion of the OTP (eg, split OTP2) from the social media providing server for the subscription request. The OTP may be automatically generated and allocated to the user terminal automatically according to the user terminal subscription request.

As such, a login procedure may be performed as the user terminal joins social media. When accessing social media using a user terminal, it is not necessary to input any information as well as a user ID as information for user authentication. More specifically, the user terminal may transmit a connection request to the social media providing server to the social media. At this time, the user terminal can automatically read the device information and the user ID and the segmented OTP 2 stored in the database connected to the user terminal and transmit a connection request including the information to the social media providing server. When the service providing server receives a connection request from a user terminal, the authentication server together with the divided OTP2 included in the connection request is read by reading the device information and the user ID included in the connection request from the database connected to the service provision server You can request OTP authentication verification by sending to. At this time, the social media providing server may transmit the user ID requesting access to the authentication server when requesting OTP authentication verification. The authentication server may perform OTP verification by restoring the divided OTP1 and OTP2 received from the social media providing server and comparing the restored OTP with the OTP stored in the database connected to the authentication server. At this time, the authentication server may receive the user ID along with the OTP authentication verification request from the social media providing server, read the OTP matching the received user ID among the OTPs stored in the database connected to the authentication server, and compare it with the restored OTP. If the authentication server succeeds in OTP verification, it can request a new OTP from the OTP server again. The OTP server may randomly generate the OTP according to the new OTP request of the authentication server and transmit the generated OTP to the authentication server. The authentication server may store the OTP received from the OTP server in a database connected to the authentication server. At this time, the authentication server discards the existing OTP stored for the user ID, stores the OTP received from the OTP server, and then splits the OTP received from the OTP server to generate two OTPs (split OTP1, split OTP2). have. When the OTP verification is successful, the authentication server may transmit the divided OTP1 and the divided OTP2 to the social media providing server. Meanwhile, if the OTP verification fails, the authentication server may transmit verification failure data to the social media providing server. The social media providing server allows access to the social media of the user terminal when the OTP verification is successful, and can also store one of the divided OTP1 and the divided OTP2 received from the authentication server, for example, the divided OTP1 in a database connected to the social media providing server. have. At this time, the social media providing server may discard the existing divided OTP1 for the user ID and device information of the user terminal and store the new divided OTP1. And, if the OTP verification fails, OTP verification failure processing is performed. When the OTP verification is successful, the social media providing server may transmit another one of the divided OTP1 and the divided OTP2 received from the authentication server to the user terminal, for example, if the OTP verification fails, the verification failure data may be transmitted to the user terminal. . The user terminal may store the divided OTP2 received from the social media providing server in a database connected to the user terminal. At this time, as soon as the user terminal is connected to the social media providing server, the user terminal can discard the existing divided OTP2 stored in the database connected to the user terminal and store the new divided OTP2.

Referring to FIG. 7, as the user terminal 110 accesses social media, a chat room to share sharing information may be generated. The user terminal 110 may enter a name through the chat room user interface 710 for creating a chat room. A chat room may be generated based on the name input from the user terminal 110. Alternatively, as at least one user is selected from the user terminal 110, selected users may be invited to the chat room. For example, as at least one or more users are selected from the first user terminal, selected users may be automatically joined to the chat room, or as users are invited to the chat room, the selected users may participate in the chat room or not. Can be involved. At this time, the chat room may include at least two or more users, and other users may be continuously added to the chat room by users invited to the chat room later.

At this time, as a plurality of chat rooms are generated from the user terminal 110, the chat room list 720 may be displayed on the user terminal 100. For example, when there are a plurality of chat rooms generated in the user terminal 110, a plurality of chat rooms may be displayed in the chat room list, and as at least one chat room is selected, a record of the conversations transmitted and received in the chat room may be displayed. have.

Referring to FIG. 8, a diagram for explaining a method of displaying shared information transmitted and received in a chat room. The social media providing server may output sharing information of users included in the chat room to the user terminal 110. For example, as the sharing information is input through the message input user interface 830 from the user terminal 110, the sharing information may be transmitted and received as a message between user terminals included in the chat room. At this time, the length or size of the message displayed in the chat room may be displayed differently according to the size of data included in the sharing information input from the user terminal 110, and identification information for each of the sharing information may be provided. As described above, the social media providing server may transmit the divided sharing information and the identification information to each of the terminals together by giving identification information to each of the sharing information, and each of the terminals may store the divided sharing information and the identification information together. . In addition, in the subsequent restoration of the specific processed shared information, it is possible to more accurately and conveniently restore the identification information related to the shared information and the divided shared information from each terminal.

The social media providing server may blur the sharing information 820 input from the specific user 811 into the chat room. Alternatively, the social media providing server may change the shared information to shared information 821 converted to private. Referring to FIG. 8A, it is an example that the sharing information is text data, and referring to FIG. 8B, it is an example that the sharing information is a video. At this time, data input through the input user interface 830 provided in the chat room (for example, a message including text data, a document file, an image, or a video) may be recognized as a message.

In addition, referring to FIG. 13, this is an example of blurring the shared information input from a specific user 811. 13(a) and 13(b), the blur treatment may be performed in various ways. At this time, the blur processing method may be set by the user as shown in FIG. 13(a) or FIG. 13(b). Furthermore, the intensity (weakly, strongly) of the blur processing can be set. For example, the intensity of the blur processing set by the user terminal is applied to the shared information and output as a message to the chat room.

Referring to FIG. 11, an example of a user interface for setting a hiding function of shared information in a user terminal is illustrated. Here, hiding may mean performing blur processing on shared information, or may mean converting it to private. At this time, the user may also select whether to convert the shared information to private or blur.

In one example, the social media providing server may provide a user interface for setting a hiding function of shared information through social media of the user terminal. In other words, when the social media is a chat service, it is possible to provide a space for setting a hiding function for shared information in a chat room provided by the chat service. More specifically, the social media providing server immediately hides the sharing information input from the user terminal 110, or the sharing information input from the user terminal 110 after a predetermined time (for example, sharing information is input) After 3 seconds), whether to hide the sharing information or when sharing information input from the user terminal 110 is not displayed on the display of the user terminal 110 (for example, sharing information shared in a chat room is continuously input) If it is not displayed on the display or when other sharing information is input in addition to the sharing information input from the user terminal in the chat room) Whether to hide the sharing information, or after the user terminal 110 enters the sharing information in the chat room, If it does not exist (for example, when leaving a chat room), a user interface may be provided as to whether to hide the shared information input from the user terminal 110. The user terminal 110 may set a hiding function through the user interface. Accordingly, the hiding function set in the sharing information input to the chat room may be applied.

Referring to FIG. 9, specific processing may be performed on shared information input from users in a chat room. At this time, the specific processed shared information may be blurred or changed to private. As described above, a method of restoring the specific processed shared information will be described. In FIG. 9, shared information converted to private will be described as an example.

As the sharing information input from the users in the chat room is displayed as private sharing information, the private sharing information 910 may be selected 920 from the specific user 811, and a reading request for the selected private information 910 may be requested. Can. The user terminal 110 may receive a request to view private shared information from a specific user included in the chat room. At this time, the private sharing information requested to be read may be shared information created by the person, or may be shared information created from the other party included in the chat room. The social media providing server may transmit a message related to a request to view private sharing information to each user terminal included in the chat room.

A message inquiring whether to approve the private sharing information requested to be viewed may be displayed on each user terminal included in the chat room. Each user terminal may input a command for accepting or rejecting a message inquiring whether to approve or not the requested shared information. The social media providing server may determine whether to accept the request for viewing the private sharing information received from each user terminal. At the same time, the social media providing server may output a message 930 notifying the user terminal requesting to view the shared information that the user is requesting authentication from other user terminals. At this time, the social media providing server may output a message 940 notifying that the authentication is completed to the user terminal requesting authentication as receiving acceptance of the request for viewing the private sharing information from other user terminals. On the other hand, if any one of the user terminals included in the chat room does not accept the request to view the private shared information, it is impossible to restore the private shared information.

The social media providing server may request a split piece of the requested shared information from each user terminal upon receiving acceptance of the request for viewing the private shared information from each user terminal included in the chat room. The social media providing server may receive fragment pieces for the corresponding sharing information from each user terminal included in the chat room, and restore private sharing information based on the received fragment pieces. The social media providing server may receive the encryption key together with the fragmentation fragment from each user terminal included in the chat room, decrypt the fragmentation fragment, and restore the shared information.

Referring to FIG. 12, an example of a user interface for setting a function for restoring shared information in a user terminal is illustrated. In one example, the social media providing server may provide a user interface for setting a restoration function of shared information through social media of the user terminal. In other words, when the social media is a chat service, it is possible to provide a space for setting a function for restoring shared information in a chat room provided by the chat service. More specifically, the social media providing server recovers each of the sharing information input from the user terminal 110, restores all the sharing information present in the chat room at once, or recovers the sharing information present in the chat unit in units of screens. You can provide a user interface as to whether or not to do it. The user terminal 110 may set a function of restoring shared information through the user interface. Accordingly, a restoration function may be applied to shared information input to the chat room.

Referring to FIG. 10, the user terminal 110 may disclose the restored sharing information 1010 with respect to the sharing information 910 input from the specific user 811, which is the sharing information requested to be viewed.

As another example, in addition to the sharing information currently being transmitted and received in the chat room, past sharing information recorded in the chat room may be restored. At this time, the restored share information may be output in the next order of the share information currently being recorded in the chat room. Alternatively, the sharing information may be output to the chat room in chronological order by comparing time information of the sharing information being transmitted and received in the chat room and time information for which the sharing information has been approved.
