1 is a view showing the configuration of a mutual file sharing system using a smartphone app according to an embodiment of the present invention, Figure 2 is a block diagram showing an embodiment.

Referring to this, the mutual file sharing system of the present invention includes a file server 2 for storing and managing a file to be transmitted and received, and one for uploading an encrypted file to the file server 2 or downloading an encrypted file stored therein. The above is comprised of the

clients

4 and 6.

The file stored in the file server 2 supports all files that can be stored and transmitted and received on the web, such as photographs, videos, media files, and document files that can be modified such as word processors.

The file server 2 of the present invention stores files to be uploaded and downloaded, and manages files to be uploaded or downloaded to limit the number of files uploaded and downloaded by the

client

4 or 6.

If a large number of files are repeatedly uploaded or downloaded in real time by a plurality of clients (4) (6), a load may be generated on the server. To prevent this, the number of uploads and downloads are checked for each client (4) (6). After counting, it manages whether the specified number of times is exceeded during the set time.

Clients

4 and 6 who have exceeded the set number of times may not be temporarily provided with uploads or downloads, or may be limited to upload or download files only after a predetermined time or below a certain size. According to an embodiment of the present invention, the access is limited when the number of up and down losses exceeds 10 times in one day, and the access may be limited even when the transmission / reception download exceeds 1Gb.

In addition, the file server 2 stores files that are unnecessary when the server is operated for a long time, or downloads of the

clients

4 and 6 that need them after uploading files of the

clients

4 and 6 are stored. This creates a load on the server.

In the present invention, the file stored in the file server 2 is automatically deleted after the preset time on the basis of the server time, if necessary after a certain time by the client (4) (6) to upload the file Can also be set to delete files by preventing them from being downloaded. In the embodiment of the present invention, if the uploaded date of the file uploaded to the file server 2 has passed one month, it is automatically deleted, and if the load occurs due to insufficient capacity of the server to check the upload date of the files The server load is reduced by sequentially deleting the first uploaded file.

The file uploaded by the client (4) (6) is stored in the file server 2, the password is set, the file server 2 maps and manages the set password with the storage file, and the client to download the stored file (4) When (6) enters a password, it matches the file with the input password and provides a download. In this case, if the file corresponding to the input password does not exist, the

client

4 or 6 is notified that the file does not exist or that the file download period has passed.

The client (4) (6) described above has a file transfer client (4) which sets a password on the file and uploads it to the file server (2) and a file receiving client (6) which downloads a file stored in the file server (2). The file receiving client 6 may be one client group 8 including a plurality of clients 6, and the file transfer client 4 and the file receiving client 6 may be changed. . In other words, the client (4) (6) for transmitting and receiving the file is not fixed, it is natural that it can be changed from time to time when file sharing is required.

In the embodiment of the present invention, the file transfer client 4 and the file reception client 6 are classified and configured for convenience of description of the configuration of the present invention.

The

clients

4 and 6 may set a user device identification (UDID), and in a preferred embodiment of the present invention, it is preferable to designate a smartphone of the

client

4 or 6 to upload or download a file.

If you set the UDID of the client (4) (6) as described above, you can overwrite the file or add more files by setting the same password again only for the previously uploaded files, if necessary It is also possible for the

clients

4 and 6 to delete it.

The client (4) (6) to modify or delete the uploaded file is managed by checking the UDID whether the file server (2) is the client (4) (6) authorized to modify and delete the file, the first uploader Permission is granted only if the client (4) (6) wishing to modify and delete the file is identified with the same UDID.

Referring back to Figures 1 and 2, the client (4) (6) of the present invention encrypts the file to be shared and uploads it to the file server (2), or download the encrypted file stored in the file server (2) Can be.

When the client (4) (6) uploads a file to be shared with the file server (2), the password is set in the file, and at this time, the password must be set to a password of more than the set number of digits set by the file server (2). You can also set passwords in multiple languages.

As an example, the password of the file may be set to eight or more alphanumeric combinations, and the password may be set to a combination of English and English characters.

In addition, when a password is set for a file, if a password already entered among the files stored in the file server 2 is used, a duplicate file is stored. Thus, if the same password is used to prevent the client 4 (6) Send a warning message to reset your password.

In the present invention, the number of times that the client (4) 6 can upload or download the file to the file server 2 is limited. If the number of times exceeds the set number, access to the file server 2 may be restricted. Can be.

If the file server 2 counts the number of accesses of the

client

4 or 6, the file is uploaded or downloaded, but the password is entered. If the password is incorrect, the file server 2 attempts to download the file by entering the password, but the file does not exist. May be included.

The client (4) (6) who uploads the file may randomly send the file to share the file with an unspecified number, where the client (4) (6) does not know who sent it to and who has downloaded it.

The file receiving client 6 may download a file encrypted by the file transfer client 4 and uploaded to the file server 2, wherein the ID or contact information of the file transfer client 4, which is an uploader, is not known. You can download the file by entering only the password set in the file.

When the file receiving client 6 downloads the file, the file server 2 checks the UDID (User Device IDentification) set by the file transmitting client 4 and transmits an acknowledgment message to the file transfer client 4 which is an uploader. do.

3 is a flowchart illustrating a mutual file sharing method using a smartphone app according to an embodiment of the present invention.

First, the file transfer client 4 to share the file sets a password on the file through the smartphone app and uploads it to the file server 2. At this time, the file transfer client 4 sets a password of a certain digit or more according to the encryption rule set in advance in the file server 2, and after setting the password, the same password is retrieved from the file server 2 or the encryption rule of the file server 2 is set. If it does not match, the password reset message is sent to the file transfer client 4, and if the correct password is set, the upload is approved.

The file transfer client 4 uploading the file to the file server 2 notifies the set password to

other clients

4 and 6 who wish to share the file to download the file. At this time, a method of sharing a password may be notified by phone, SMS, messenger, or mail.

The file uploaded by the file transfer client 4 is managed by the file server 2, and classified and stored with matching uploaded file and password, and waits for file transfer until the request of the file receiving client 6 is requested. .

The file receiving client 6, which has received the password from the file transfer client 4, attempts to download the file by inputting the password set in the file to be received through the smartphone app, and the file server 2 receives the file receiving client 6 The file matching the input password is transmitted to the file receiving client 6 when the download request is inputted by the password. The file receiving clients 6 may be plural, and the file receiving clients 6 belonging to the plurality of client groups 8 may download simultaneously.

The file server 2 responds to an error message if the password inputted by the file receiving client 6 is incorrect or a matching file does not exist, and the client 4 is not allowed if a continuous password input error occurs. (6) by deliberate access, denying the right to download files. As an example, if an incorrect password input error occurs more than five times, access to the file is restricted.

After the file download of the file receiving client 6 is completed after inputting the permitted authority of the file server 2, that is, the correct password, the UDID of the file receiving client 6 is checked to confirm the reception time and the file transfer client ( 4) You can confirm by acknowledging.
