Description

TECHNICAL FIELD [0001] The present invention relates to a file sharing method and system using a mail message,

The present invention relates to a file sharing method and system, and more particularly, to a file sharing method and system using a mail message such as e-mail.

A file sharing system is a system that stores a file in a DB server such as a web hard and downloads a file according to a user's request in order to allow file sharing among users by using the Internet.

In a conventional file sharing system, when a user uploads a shared file through an upload client, another user searches the uploaded shared file by category, file name, and the like, and downloads the retrieved file to the user's device such as a PC.

In this process, the user has to go through a troublesome login authentication process to download the desired data or files, and it takes a lot of time to access desired files, such as installing ActiveX for downloading separately.

On the other hand, there is an inefficiency in that the data including large files are restricted in terms of the transmission speed and the storage capacity to be shared among users by mail, messenger, and wireless network.

When a first user registers a shared file, an e-mail message including a URL address for downloading the shared file is sent to the mail account of the second user so that the second user can perform the login authentication procedure, It is an object of the present invention to provide a file sharing method and system using a mail message that can easily download a desired file or the like through a URL address without going through a troublesome procedure.

The objects of the present invention are not limited to the above-mentioned objects, and other objects and advantages of the present invention which are not mentioned can be understood by the following description and more clearly understood by the embodiments of the present invention. It will also be readily apparent that the objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.

In order to achieve the above object, a file sharing method using a mail message according to the present invention includes: a DB server registering a shared file uploaded from an upload client through a first client terminal, the management server using token information of the shared file Generating a URL address for downloading the shared file, generating a mail message including a URL address of the mail server, and sending the mail message to a mail account of a second user, When the user accesses the URL address, the second user terminal downloads the shared file from the DB server via the download client.

In addition, the file sharing system using the e-mail message of the present invention includes a DB server for registering a shared file uploaded from the first user terminal through an upload client, a URL server for downloading the shared file using the token information for the shared file, A mail server that generates a mail message including the URL address and sends the mail message to a mail account of a second user, and, when the second user who receives the mail message accesses the URL address, And a second user terminal for downloading the shared file from the DB server through the second user terminal.

According to the present invention as described above, when a first user registers a shared file, an e-mail message including a URL address for downloading the shared file is sent to the mail account of the second user, It is easy to download data such as a desired file through a URL address without going through troublesome procedures such as a procedure, an ActiveX installation, and the like.

The above and other objects, features, and advantages of the present invention will become more apparent by describing in detail exemplary embodiments thereof with reference to the attached drawings, which are not intended to limit the scope of the present invention. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to denote the same or similar elements.

In one aspect of the present invention, when the first user uploads the shared file to the DB server, the DB server registers the shared file, and the management server uploads the token information (the token information includes, for example, (ID, member number), mail account information of the first user, category information of the shared file, title information of the shared file, description information of the shared file, address information of the DB server in which the shared file is stored, , And the mail server generates a URL address for downloading the shared file by using the mail address including the URL address, and sends the mail message including the URL address to the mail account of the second user do. The second user can access the URL address and download the shared file registered in the DB server through the download client.

In another aspect of the present invention, a friend relationship may be established between a first user and a second user for file sharing using a mail message. More specifically, the second user is a user included in the friend list of the first user. To this end, a bulletin board for promoting the shared file uploaded by the first user may be provided. When the second user confirms the postings uploaded by the first user through the bulletin board and subscribes to the friend relationship, the mail account of the second user is added to the friend list of the first user.

In one embodiment of the present invention, a mail message may be sent only to a second user who is set to a friend relationship with the first user. Also, the first user and the second user can be set to mutually accept / deny receiving / sending mail messages.

1 is a configuration diagram of a file sharing system using a mail message according to an embodiment of the present invention. Referring to FIG. 1, a file sharing system using a mail message according to the present invention includes a first user terminal 102 for a first user to upload a shared file, a DB server 104 for registering an uploaded shared file, A management server 106 for generating a URL address for downloading, a mail server 108 for sending a mail message including a URL address, and a second user terminal 110 for downloading a shared file at the request of the second user .

In one embodiment of the present invention, the file sharing system using a mail message further includes a user management unit 112 for establishing a friend relationship between the first user and the second user, and a point management unit 114 for managing users' points .

The DB server 104 functions to register a shared file uploaded from the first user terminal 102 via the upload client. The first user terminal 102 refers to a device capable of executing an upload client for uploading a file such as a PC or a smart device.

Preferably, when the upload client is executed in the first user terminal 102, the DB server 104 extracts the hash value of the shared file uploaded by the first user through the upload client, It is possible to judge whether or not the file exists. Here, MD5 (Message-Digest Algorithm 5) can be used for the hash method. MD5 is a 128-bit encrypted hash function that is mainly used to determine whether a program or file is identical, or to check integrity of the original.

As a result of the determination, if there is no file having the same hash value in the DB server 104, the DB server 104 stores the shared file. The first user terminal 102 may receive the server number of the DB server 104 and upload the shared file to the DB server 104 of the server number using the FTP protocol. The FTP protocol is defined as a file transfer protocol, and is a protocol for transferring files between a server and a client.

If a file having the same hash value exists in the DB server 104, the shared file is virtually uploaded. In this case, since the file having the same hash value exists in the DB server 104, uploading of the shared file via the FTP protocol is not performed, and the upload is virtually performed.

The management server 106 performs a function of generating a URL address for downloading the shared file using the token information for the shared file. The token information is a token-encrypted information for accessing the shared file, such as identification information such as the data number of the uploaded shared file, mail account information of the user, and category information of the shared file.

Preferably, the token information includes at least one of an ID of a first user who uploads a shared file, first user information such as a membership number, mail account information of a first user uploading the shared file, category information of the shared file, Information of the shared file, description information of the shared file, DB server information stored in the shared file, and identification information of the shared file.

Preferably, the token information may be encode / decode converted by a JSON (Java Script Object Notation) method by the management server 106. JSON is a way of expressing data or files when sending or receiving data over the Internet. There is no restriction on the type of data or file, and it is particularly suitable for expressing the value of a variable in a computer program. JSON conforms to the syntax of JavaScript, but can be used in a variety of programming languages because it can be implemented independently of the programming language or platform.

In particular, the JSON approach is advantageous in a web environment where JavaScript is frequently used. Recently, JSON parser function is embedded in Web browser environment such as Mozilla, Firefox, Explorer, Opera, Safari, and Chrome, so it is possible to use this function more safely and faster.

In one embodiment of the invention, a friend relationship may be established between the first user and the second user. The second user can apply for a friend relationship with the first user through a bulletin board for promoting the shared file uploaded by the first user.

When the shared file is registered in the DB server 104, the management server 106 searches for a second user set as a friend relationship with the first user who uploaded the shared file. The management server 106 extracts the second user who has entered the category and keyword corresponding to the token information of the searched second user.

The second user can pre-designate the category or keyword of the desired data. For example, it is assumed that a second user specifies a category of a file as an action. When the action movie file is registered in the DB server, the management server 106 can extract the user who designates the category of the second user set as the friend relationship with the first user as the action.

The management server 106 generates a URL address for downloading the shared file by the second user extracted using the token information.

Preferably, the management server 106 may generate the URL address using the Crypto encryption method using the token information for the shared file. Cryto is a kind of AES 128-bit public key algorithm cryptosystem, which can encrypt and decrypt symmetric keys.

The management server 106 may be a Redis server method, such as a No-SQL DB, in which data is basically stored in a memory in the form of a key and a value pair and the stored contents are synchronized.

The mail server 108 generates a mail message including the URL address, and sends the mail message to the mail account of the second user. The mail server 108 may generate a mail message including the URL address according to a previously prepared mail format and send the generated mail message to the mail account of the second user via the mail protocol SMTP.

The second user terminal 110 downloads the shared file from the DB server 104 through the download client when the second user who receives the mail message accesses the URL address.

Preferably, when the download client is executed, the second user terminal 110 transmits a shared file (e.g., a server number of the DB server) stored in the shared file through the FTP protocol using the hash value of the shared file, Can be downloaded.

Here, the information about the first user who uploaded the shared file and the information about the second user who downloaded the shared file may be recorded in the log of the DB server 104.

In one embodiment of the present invention, a user management unit 112 for managing a friend relationship between the first user and the second user may be further included.

The user management unit 112 provides a bulletin board for promoting the shared file uploaded by the first user. When the second user subscribes to the friend relationship with the first user through the bulletin board, You can add it to your friends list. In this case, the second user may only refer to the user included in the friend list of the first user among the users using the file sharing system.

In another embodiment of the present invention, a method of paying a reward point to a first user uploading a shared file or exhausting a packet point of a second user downloading a shared file may be applied.

When the second user downloads the shared file, the point management unit 114 may provide a predetermined reward point to the first user who uploaded the shared file.

In this embodiment, the second user terminal 110 inquires the remaining user packet point of the second user from the point manager 114, and only when the remaining packet point is at least a predetermined packet point necessary for downloading the shared file, As shown in FIG.

According to the file sharing system using the e-mail message of the present invention as described above, the login authentication process for accessing the web hard, the process of searching for a large amount of data, installing a download client, It has the advantage of downloading the desired data from all devices that can access to the mail account such as user's PC, PMP, smart phone regardless.
