Referring to FIG. 1, a web storage server 10 providing a storage space on the web, a user terminal 30 of a user subscribed to the web storage server 10, and a user not subscribed to the web storage server 10. And a guest terminal 50.

The user terminal 30 and the guest terminal 50 are terminals capable of accessing the web storage server 10 through a communication network. The user terminal 30 and the guest terminal 50 are not only a computer device as shown in the drawing but also a mobile communication terminal such as a mobile phone and a personal digital device ( PDA (Personal Digital Assistants) may be applied.

The web storage server 10 includes a storage space such as a hard disk, and allocates some space to the registered users. Since a service device such as Webhard still provides a service for allocating storage space, a detailed description thereof will be omitted.

A member user of the web storage server 10 may manage a storage space allocated to the user in the form of a hard disk, and may create and manage a plurality of folders according to a tree structure.

Particularly, when the member user sets any folder as a secure shared folder, the web storage server 10 according to the present embodiment may include a password formed of an authentication number (for example, a number, a letter, a symbol, or a combination thereof) in the secure shared folder. When a secure shared folder with an authentication number is created, access address information (for example, a URL (Uniform Resource Locator), etc.) that can be directly accessed to the secure shared folder is created. To send. Therefore, there is no need to log in by inputting an ID and password after accessing the web storage server 10 separately, and then directly accessing the secure shared folder using the access address information. Of course, when any terminal (for example, the user terminal 30 or the guest terminal 50, etc.) attempts to access the secure shared folder using the access address information, the web storage server 10 is secure connection Enter the authentication number entered when creating the folder, and allow access to the secure shared folder only if the correct authentication number is entered. The guest terminal 50 accessing the secure shared folder using the access address information is preferably not allowed to access other storage spaces of the member user other than the secure shared folder.

Here, the guest terminal 50 refers to a terminal that accesses a secure shared folder without logging in to the web storage server 10, and must be a terminal of a user who is not a member of the web storage server 10. None is natural. That is, the guest terminal 50 refers to a terminal that requests access to a specific storage space without logging in by inputting an ID and password into the web storage server 10.

When a member user who is a member of the web storage server 10 wants to provide a file in an arbitrary folder stored in his or her storage space to another person, a secure connection folder of the web storage server 10 is created and the access address information thereof. And providing the authentication number to the other person, the other person attempts to access the secure access folder with the access address information using his terminal (that is, the guest terminal 50), and the web storage server 10 When you have finished entering the requested authentication number from, you can access the files in the Secure Access folder.

Therefore, according to the present embodiment, even if a member subscriber of the web storage server 10 wants to transmit a file in a storage space on the web to another person, there is no need to expose his / her ID and password to the other person. By setting only a shared folder as a secure shared folder, you can secure the storage space on the web allocated to you.

Referring to FIG. 2 according to another embodiment, the web storage server 10 may use a message service (eg, a short message service (SMS), a multimedia message service (MMS), etc.) provided by the mobile communication network 70. The access address information is transmitted to the mobile communication terminal 200 designated by the member user. Of course, the authentication number may also be provided through a message service together with access address information.

That is, when a member user who is a member of the web storage server 10 wants to provide a file in an arbitrary folder stored in his or her storage space to another person, a secure access folder of the web storage server 10 is created, and When the access information transmission service is selected by inputting a mobile phone terminal number of another person, the web storage server 10 transmits the access address information and the authentication number to the mobile communication terminal 200 according to the phone number. Therefore, the other person who receives the message including the access address information and the authentication number to the mobile communication terminal 200 is connected to the access address information using the Internet-enabled terminal (ie, the guest terminal 50 or the mobile communication terminal). When the connection to the secure access folder is attempted and the input of the authentication number requested from the web storage server 10 is completed, the files in the secure access folder can be accessed.

Here, the member user of the web storage server 10 may request the web storage server 10 for a message that he wants to leave in a message transmitted to another person. That is, when a phone number of another person is input, a message to be transmitted is input together, and the message transmitted by the web storage server 10 to the mobile communication terminal according to the corresponding phone number includes access address information, an authentication number, and the comment.

Hereinafter, the configuration and functions of the web storage server 10 will be described.

Referring to FIG. 3, the web storage server 10 according to the present embodiment includes a storage unit 310, a message sending unit 330, and a main control unit 350, and the storage unit 310 includes a hard disk unit ( 312, a member information storage unit 314 may be included, and the main controller 350 may include a connection information generator 352, a message generator 354, and an authentication processor 356.

The hard disk unit 312 of the storage unit 310 is a storage space allocated to members, and the member information storage unit 314 includes personal information about members' IDs, passwords, allocated storage disk spaces, and the like. Information about the secure shared folder (hereinafter referred to as "shared folder information") is stored. The shared folder information may include a folder name, an access address information, an authentication number, etc. of the secure shared folder. When the member user sets the sharing period of the secure shared folder, the shared folder information may further include "sharing period information." That is, when the member user sets the sharing period of the secure shared folder to, for example, "3 days", the member user blocks access so that others cannot access when the sharing period has elapsed.

In addition, the member information storage unit 314 may further store information (telephone number, etc.) for the mobile communication terminal that has transmitted the message including the access address information and the authentication number. For more stable security of access to the secure shared folder, the above-mentioned telephone number may be used when performing secondary authentication through mobile authentication in addition to the authentication number. That is, when the first authentication for the authentication number is completed, the web storage server 10 sends a message with the second authentication number attached to the mobile communication terminal according to the pre-stored phone number, and requests the access from the guest terminal 50. If a second authentication number is entered, access to the secure shared folder is allowed. Here, if there is a plurality of phone number information of the mobile communication terminal stored in the member information storage unit 314 (that is, when there are a plurality of mobile communication terminals that have transmitted a message including access address information and authentication number), secure sharing After obtaining the phone number information from the guest terminal 50 requesting access to the folder, if there is a match with the stored phone number information, if there is a match, the second authentication number is sent to the corresponding phone number, and after the second authentication to the secure shared folder. Allows access to

Here, the hard disk unit 312 and the member information storage unit 314 allocated to the members may be separated into separate storage media, but may be configured as one medium but logically divided.

As described above, the message sending unit 330 transmits a message through the mobile communication network to the mobile communication terminal according to one or more telephone numbers input from the member user. Since a specific server on a communication network transmits a message to a mobile communication terminal through a message transmission service such as SMS through a mobile communication network, a detailed description thereof will be omitted.

The main control unit 350 generates the access address information to the secure shared folder set by the member user and provides it to the member user (of course, it can be provided to the mobile communication terminal according to the telephone number set by the user as described above). The storage unit 310 and the message sending unit 330 may be configured to determine whether to allow the access to the guest terminal 50 requesting access to the corresponding secure shared folder using the access address information after performing authentication by the authentication number. To control.

If the member user sets a secure shared folder in some of the storage spaces to be managed, the access information generation unit 352 of the main storage unit provides access address information (for example, http: // www) accessible to the secure shared folder. It creates a URL such as .web-storageserver.com / user1 / folder1 ). The access address information generated as described above may be provided to the member user (for example, displayed on the personal page of the member user among the websites provided by the web storage server 10, or the member user dials a phone number. It may be provided in the form of a text message to the mobile communication terminal registered in advance), it may be provided through the mobile communication network to the mobile communication terminal of another person set by the member user.

The message generating unit 354 functions to generate a message including access address information and a set authentication number to the secure shared folder set by the member user, and the generated message is a mobile communication terminal according to a phone number set by the member user. Is provided.

The authentication processing unit 356 performs a function of authenticating whether or not the guest terminal 50 that has requested access to the secure shared folder has been accessed. Since a detailed description of the authentication method has been described above, repeated descriptions will be omitted, and a process thereof will be described later with reference to FIGS. 4 and 5.

Hereinafter, a process of sharing a storage space on the web according to the present invention will be described.

4 and 5 are flowcharts illustrating a storage sharing process on a web according to an embodiment of the present invention.

Referring to FIG. 4, when a registered user accesses and logs in to the web storage server 10 using his or her user terminal 30 (S410), and sets an arbitrary folder as a secure shared folder in which an authentication number is set. In operation S 415, the web storage server 10 generates access address information for the secure shared folder in operation S 420, and provides the access address information to the user terminal 30 in operation S 425. As described above, the web storage server 10 may provide the access address information to the mobile communication terminal of the member user.

The web storage server 10 stores information on the corresponding secure shared folder (for example, folder name, access address information, authentication number, etc.) (S430). Of course, the storage of the information on the secure shared folder may be performed before step S420.

Subsequently, the member user informs the access address information and the authentication number, or the other person who receives the access address information and the authentication number as described above accesses the user terminal (ie, the guest terminal 50). When requesting access to the secure shared folder of the web storage server 10 by the address information (S435), the web storage server 10 requests the authentication number to the guest terminal 50 (S440). For convenience of understanding, for example, a user of the guest terminal 50 who attempts to access a secure shared folder may receive a web page requesting an authentication number.

When the web storage server 10 receives the authentication information in the form of an authentication number from the guest terminal 50 (S445), by comparing the received authentication information and the authentication number to determine whether or not the correct authentication number (S450), authentication If the information and the authentication number does not match, an error process (S455).

If the same as the previously stored authentication number, the web storage server 10 allows the guest terminal 50 to access the corresponding secure shared folder (S460). For example, the web storage server 10 provides the guest terminal 50 with a web page for identifying a file or folder belonging to a secure shared folder corresponding to the access address information.

Referring to FIG. 5 according to another embodiment of performing second authentication, a registered user accesses and logs in to the web storage server 10 using his or her user terminal 30 (S510), and optionally a folder. In setting the security shared folder with the authentication number, if one or more mobile communication terminal telephone numbers are input (S515), the web storage server 10 generates access address information to the secure shared folder (S520), and the input is performed. The message containing the access address information and the authentication number is sent to the received phone number (S525). That is, the message is sent to the mobile communication terminal 200 of another person as shown in FIG. Here, of course, the access address information may also be provided to the member user.

The web storage server 10 stores information related to the corresponding secure shared folder, such as access address information, an authentication number, and a mobile phone terminal number (S530).

Subsequently, another person who has received the access address information and the authentication number through the mobile terminal as described above uses the terminal (i.e., the guest terminal 50) as a secure shared folder of the web storage server 10 as the access address information. When requesting access to the (S535), the web storage server 10 requests the authentication number to the guest terminal 50 (S540).

When the web storage server 10 receives the authentication number from the guest terminal 50 (S545), it determines whether it is a valid authentication number (S550), and if it is the same as the previously stored authentication number according to the generation of the secure shared folder. The secondary authentication number for the second authentication is generated and transmitted to the phone number of the input mobile communication terminal (S555). Here, if there are a plurality of stored phone numbers of the mobile communication terminal, the web storage server inquires the phone number to the guest terminal 50, and if the phone number corresponding to the received phone number is stored, the phone Send the second authentication number to the number.

When the web storage server 10 receives the second authentication information in the form of the second authentication number from the guest terminal 50 (S560), it determines whether or not the same authentication number as the second authentication number transmitted to the mobile communication terminal (S560). In operation S565, if the determination result does not match, error processing is performed (S570), and only the same case is allowed to access the corresponding security shared folder (S575).

The method of the present invention as described above may be implemented in a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention is not limited to the above embodiments, and many variations are possible by those skilled in the art within the spirit of the present invention.
