While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail.

It should be understood, however, that it is not intended to be limited to the particular embodiments of the invention but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. Like reference numerals are used for like elements in describing each drawing.

The present invention relates to a method and system for sharing a file based on a telephone number stored in a user terminal. Specifically, information on the user list corresponding to the telephone number stored in the user terminal and information on the files of people corresponding to the telephone number are displayed on the user terminal in an icon form, If the user selects one of the icons, the file can be downloaded to the user terminal. As a result, the user terminal can share a file stored by another user based on a telephone number stored therein.

In the past, when a user wanted to share a file of another person, he had to contact another person, receive a file separately, or download another person to the web hard. As a result, the process of sharing files was complicated.

However, since the file sharing system of the present invention shares a file of another person based on a telephone number, the process of sharing the file is easy.

In addition, from the viewpoint of file provisioning, the user can store the file stored by himself / herself in a server having a large storage space and share it with another person, so that it is possible to manage a large amount of data from his own terminal with small capacity, .

Furthermore, the user can save only the files selected by the user without saving all the files stored in the server to the server, share the files with other users, and maintain the security of the files as a result.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Also, a file sharing system using a user terminal is defined as a file sharing system.

1 is a diagram illustrating a file sharing system according to an embodiment of the present invention.

1, a file sharing system 100 includes a server 5 that receives, stores, and provides files to user terminals 1, network 2, and user terminals 1 .

The user terminal 1 may provide a communication means to a user and may provide various files, for example, a mobile terminal, a PDA, a smart phone, a tablet PC, and the like.

Also, the user terminal 1 may include a file sharing application which can automatically transmit a stored telephone number or restrict user access, transfer and share a file, which will be described later.

The network 2 is a communication connection path between the user terminals 1 and the server 5, and may be one communication network or a plurality of communication networks.

The server 5 can download the files stored by the user terminals 1 and store them on a user-by-user basis. When a specific user requests a file of another user, the server 5 transmits the file to the user so that users can share the file .

The server 5 may include an information processing program, for example, a telephone number information automatic storing program 10, a telephone number information matching program 11, a file storing program 12, a file sharing setting program 13, A user access restriction setting program 14, a file access restriction setting program 15, a file information merging program 16, and a user classification program 17, for example.

In addition, the memory for storing information processed by the program of the server 5 may be a memory for storing telephone number information, telephone number matching information, file information, file sharing information, user access restriction information, file access restriction information, Classification information.

The telephone number information automatic storing program 10 of the file processing program is a means for processing information such as a name of a user of the user terminal 1, a user's terminal telephone number, an e-mail address, .

When the telephone number or the like is automatically stored in the user terminal 1 and automatically transmitted to the server 5, the telephone number information automatic storing program 10 converts the telephone number into a hash code and processes the converted file to be stored in the user information can do. The encryption method of the user file may be performed by a method other than the conversion into the hash code.

The automatic phone number information storing program 10 converts the user file into a hash code, thereby solving the security problem that may occur due to leakage of the personal file.

The telephone number information can be converted into a hash code by the automatic telephone number information storing program 10 and stored in the memory.

The telephone number matching program 11 is a program for judging whether individual users' personal files are mutually stored when a user of the user terminal 1 stores personal files of other users.

Further, the matching information is processed in the user information matching program 11 and stored in the memory.

Therefore, the telephone number information matching program 11 can simplify the procedure of the file sharing method by storing the telephone number list in which the telephone numbers are mutually stored among the users in the memory and providing them to the user terminal 1. [

The file storage program 12 is a program for processing various information such as a file stored in the user terminal 1 so as to be stored in.

The file storage program 12 is a means for processing information stored in the user terminal 1 so as to store documents, pictures, moving pictures and the like in the server 5 so that the files can be permanently stored in the allocated memory.

The file information stored in the memory is stored using the space allocated in the memory as information including the document, photograph, and image information, so that the file information can be permanently stored for use at any time.

The file sharing setting program 13 is a program that can be used by sharing a file stored in the user terminal 1 with another user and is a program for allowing access to a shared file to another user.

The user access restriction setting program 14 is a program that can block users from accessing a shared file even if a personal file is stored between the users.

A program related to security of a file, and access by a user to a shared file may be blocked according to a command signal sent from a user terminal.

As a result, the file access provider can select and approve the file sharer by the user access restriction setting program 14, and can further provide only the selected file.

The file access restriction setting program 15 can selectively restrict access to the files according to the type of the file even if the user is permitted to access the file.

The file merging program 16 is a program that can merge the respective groups when the user A forms a plurality of file groups. The file merging program 16 is a program for merging a plurality of files and users into one new group Can be processed.

The file merge program 16 can facilitate mutual access between the shared groups of the shared files by merging the shared files and the shared groups.

The user classification program 17 is a program that can selectively open a file by selecting a file sharer for each file to be shared. If there is a need to maintain the security, the user classification program 17 may not disclose some files.

As a result, when the user's telephone number stored in the user terminal 1 is matched using the server 5 including the above-mentioned program, the file sharing system 100 can obtain the stored user telephone number list and the stored telephone number It is a system that provides sharing of files stored by users.

2 is a flowchart illustrating a file sharing method according to an embodiment of the present invention.

Hereinafter, a process of sharing a file in the file sharing system 100 of the present invention will be described. For convenience of explanation, it is assumed that the user A stores the telephone number and the file in the server 5 via his / her user terminal 1A.

2, the user terminal 1A of the user A automatically transmits information (hereinafter referred to as "telephone number information") stored in the user terminal 1A to the server 5, The server 5 automatically stores the transmitted telephone number information in a storage space allocated to the user A (S1).

Meanwhile, the telephone number information may be automatically transmitted to the server 5 in the form of a telephone number list. Of course, the transmission of the telephone number to the server 5 may be done manually at the request of the user.

According to one embodiment, the user A can execute a file sharing application installed in his / her user terminal 1A, and the phone number information can be transmitted to the server 5 after execution of the application.

Specifically, when the user A executes the file sharing application of the user terminal 1A, the server 5 requests the user terminal 1A for the telephone number information or requests the update of the telephone number information, The user terminal 1A may transmit the current telephone number information to the server 5 in response to the request of the server 5 and the server 5 may match and store the transmitted telephone number information to the user.

All of this process can be performed automatically between the file sharing application and the server 5 without user A intervention.

According to another embodiment, the telephone number information may be automatically stored in the server 5 regardless of the execution of the application.

Then, the file sharing application automatically transfers the files stored in the user terminal 1A to the server 5, and the server 5 may store the transferred files in the storage space of the user A (S2).

Subsequently, when another user (hereinafter referred to as a "file sharer") who wants to share a file of the user 1A requests sharing of the file with the server 5 using his / her user terminal (S3), the server 5) may transmit the file to the sharer (S4). For example, when the user A has stored the file stored in the server 5, the user A transmits the user A to the user terminal 1B of the file sharer B storing the telephone number of the user A And a file stored by the user A may be displayed in the form of an icon. If the file sharer B selects one of the icons, the server 5 displays the icon The file corresponding to the selected icon can be transmitted to the user terminal 1B of the file sharer B. [ As a result, the file sharer B can share the file held by the user A via the server 5.

In summary, in the file sharing system 100 of the present invention, a user can share a file with another person only by storing a telephone number and a file in a user terminal.

Although not mentioned above, users may be subscribers to the file sharing service, and file sharing services may be performed only between subscribers.

According to another embodiment, the server 5 transmits a file list including information of files stored by all users corresponding to the telephone numbers registered in the user terminal 1A of the user A to the user terminal 1A ). ≪ / RTI > In this case, the user A can select a desired file from the file list and download it from the server 5 without selecting a specific user included in the user list.

3 is a diagram illustrating a process of automatically transmitting a telephone number stored in a user terminal to a server according to an embodiment of the present invention.

Referring to FIG. 3, the automatic telephone number transmission program can automatically transmit the telephone number information stored in the user terminal 1A to the server 5.

The server 5 searches for a file stored by the users registered in the telephone number based on the transmitted telephone number information and transmits a user list including information on the file stored by the registered users to the user terminal Lt; / RTI >

For example, if the user A has stored the telephone numbers of the file sharers B, C, and D, the server 5 searches the file sharers B, C, And transmit the user list including the information about the files stored in the file sharers B, C, and D to the user terminal 1A of the user A. [ As a result, the user A can confirm the information on the files held in the file sharers B, C, and D registered with the telephone number through the user list.

FIG. 4 is a diagram illustrating a process of automatically storing a file stored in a user terminal in a server according to an exemplary embodiment of the present invention.

4, the file automatic transmission program of the user terminal 1A may transmit a file stored in the user terminal 1A to the server 5 by a command of the user or automatically.

The server 5 may store the file transferred from the user terminal 1A in a storage space allocated to the user and may provide the stored file to the other user upon another user's request.

On the other hand, when the user belongs to a specific group, the file transmitted from the user terminal 1A may be stored as a storage space allocated to the group. That is, the files transmitted from the members of the group may be stored together in the storage space.

According to another embodiment, for example, the files stored by the users corresponding to the telephone numbers registered in the user terminal 1A of the user A are copied from the server 5 to the storage space corresponding to the user A And may provide the information about the stored files to the user list and match it to the user list.

5 is a diagram illustrating a file sharing method according to an embodiment of the present invention.

Referring to FIG. 5, a user list matched to a telephone number may be generated in the user terminal 1B.

When a user of the user terminal 1B selects a specific item from the user list, for example, a user A item, the list of files stored by the user A in the server 5 is stored in the user terminal 1B It can be viewed on the current screen or another screen.

According to another embodiment, a list of files provided by the providers next to the names of the file providers may be shown when the user list is shown on the user terminal 1B.

When the user selects a desired file from among the list of files to be viewed, a file corresponding to the selection may be provided from the server 5 to the user terminal 1B. In this case, since the user terminal 1B stores a new file, the stored new file can be stored in the server 5.

According to another embodiment, since the file newly stored in the user terminal 1B is the same as the file already stored by the user A, the server 5 does not download the file from the user terminal 1B, Only the link corresponding to the stored address can be added to the list of users' files. A detailed description thereof will be described later.

According to another embodiment, when the user A selects a desired file from among the list of the files to be displayed, the file corresponding to the selection can be stored in the user's storage space in the server 5. Of course, as described later, the file itself may not be stored in the storage space of the user, and only a link to the space where the file is stored may be stored in the storage space of the user A.

In summary, the file sharing method of the present invention generates a user list based on the telephone number stored in the user terminal, and the files stored by the user terminals are manually or automatically down-loaded into the server 5 and stored for each user. The file list having information on the stored files is matched to the user list, so that a specific user can check items of files owned by other users from the user list displayed on his / her user terminal, At least a part of the files can be selected and the corresponding file can be provided from the server 5.

For example, when the file sharer B selects an item of a specific file of the user A from the user list displayed on the user terminal 1B, the user terminal 1A of the user A sends the file A to the server 5 A file corresponding to the above-selected selection, for example, a "cookie run file" can be downloaded from the server 5 to the user terminal 1B. As a result, the file sharer B can confirm the list of files of another person by sharing only the telephone number of the user A, and can share a specific file with the user A.

In the above description, the file sharing method in the case where the user A and the file sharers B, C, and D do not belong to a specific group is described. However, when the user A and the file sharers B, It can also belong to a group. In this case, the files stored by the user A and the file sharers B, C, and D can be downloaded to the storage space of a specific group in the server 5, and icons of all files stored under the group are included A list of files may be displayed to the members of the group.

For example, when the user A selects an icon corresponding to a member of the group among the user list, not only files stored by the selected member but also information about files stored by all members of the group May be displayed on the user terminal of the user (A).

6 is a diagram illustrating user access restriction and file access restriction by the user A according to an embodiment of the present invention.

For file requests from file sharers, user A may restrict the file sharers to receive the file (R1).

Even if a large number of users exist in the sharers B, C, D, E, F and G requesting the files as shown in FIG. 6, the user A restricts only some of the file sharers B, (R1).

Further, as shown in FIG. 6, the user A may selectively provide his or her file to the file sharers B, C, and D (R2).

For example, the user A can selectively disclose only a1 and a5 of his / her own files for the file sharer B, and selectively open a1 and a2 for the file sharer C .

Therefore, the user A can selectively provide the file sharers B, C, and D and the shared files a1, a2, and a3 to be provided with the file, thereby facilitating security maintenance and management of the file.

7 is a diagram illustrating a file sharing system for performing multi-user file sharing according to another embodiment of the present invention.

7, when a group in which a user A selects file sharers B, C, and D and shares a file is formed, the file sharers B, C, To the file sharing group G1 so that the file sharing group G1 can share the file.

Furthermore, the user A can set the file sharers B, C, and D in the same manner for the file provided by the user A, such as the user access restriction by the file provider and the file file access restriction.

At this time, in order to facilitate file management, the user access restriction setting program 14 sets the user classification markers 50-1, 50-2, and 50 of the file sharers B, C, and D except for the user A -3 .....) is formed as the number of file sharers, and it is possible to set whether or not each file is disclosed by using the access restriction setting program 15.

For example, the a1 file among the files a1, a2 and a3 owned by the user A can be set to be disclosed only to the file sharer B among the file sharers B, C and D, It can be set to be disclosed only to the sharers C and D.

The other file sharers B, C and D can also perform the same role as the user A. As a result, only the files which are allowed to be shared by the respective user terminals 1A, 1B, 1C and 1D As shown in FIG. 6, the user terminals 1A, 1B, 1C and 1D can confirm that different files are shared.

Furthermore, deletion and addition of the shared files a1, a2 and a3 are possible only for the user A who provided the shared files a1, a2 and a3, and likewise for the file sharers B, C and D Even if the file (b1, b2 .. c1, c2, .. d1.d2 ...) is provided, the owner of the original shared file has the right to delete and add.

As a result, file providers can prevent file corruption by others in the file sharing group G1 by deleting and adding only their own files.

8 (a) to 8 (c) are diagrams showing a file sharing method in the case where a file according to another embodiment of the present invention is provided redundantly.

As shown in Figs. 8 (a) to 8 (c), when the user B stores the same file a1 as the user A and the file a1 of the user A is stored in advance in the server 5). ≪ / RTI >

In this case, before the server 5 downloads the file from the user terminal 1B of the user B via the same file recognition program 18, the file to be downloaded from the user terminal 1B is stored in the file It can be judged first whether or not it is the same.

Specifically, the same file recognition program 18 can determine whether the name of the transferred file later is the same as the existing file.

Then, the same file recognition program 18 judges whether or not the file capacity is the same if the names of the files are the same, for example, judges whether the file data of a certain range is the same, Can be detected.

A certain range of data can be set to a range of 40 bytes, and it is also possible to set a wider data range for accuracy if necessary.

When it is determined that the file a1 of the files to be downloaded from the user terminal 1B of the user B to the server 5 is the same, the server 5 is not the same as the one shown in Fig. 8 (b) The files b2 and 3 can be downloaded from the user terminal 1B and the same file a1 can store only the link a1. Of course, although the server 5 may download the same file al from the user terminal 1B, there is a problem that the storage space of the server 5 is wasted.

Therefore, the server 5 can store only the link without downloading the same file al.

Specifically, the link # a1 indicates the address of the storage space where the same file a1 is stored in the server 5, that is, the address of the storage location of the file a1 in the storage space of the user A, As a result, the link (# a1), the file sharer B and the file sharer C will be shown in the file list matched with the user list of the file sharer C storing the telephone number of the file sharer B. When the file sharer C selects the link (# a1), the server 5 reads the file a1 from the storage space of the address corresponding to the link (# a1) and stores the read file a1 in the file sharer To the user terminal 1C of the user terminal C. [ Of course, in this case as well, since the file sharer C stores the same file a1, the same file a1 is not stored in the storage space of C in the server 5, but only the link to the same file a1 Will be stored in the storage area of the file sharer (C).

Such link creation and storage and link information display on the file list can be automatically performed by the server 5. [

According to another embodiment, at least some of the operations associated with the link may be done manually.

For example, it is possible for the user B to recognize that the file a1 is the same file through the user terminal 1B and to select whether or not to provide the file a1.

For example, the user terminal 1B may display a popup window indicating that the same file a1 is displayed on the screen, and the user B may provide the file a1 stored in the user terminal 1B to the server 5 And whether or not it is acceptable.

The server 5 may generate a link to the same file a1 as shown in FIG. 8 (b) according to the selection of the user B, a1) may be downloaded from the user terminal 1B and stored redundantly.

In summary, in the file sharing method of the present embodiment, if another user stores the same file as the file stored in the server 5, the same file can be downloaded and duplicated or only the link to the same file can be stored. In consideration of the storage space efficiency of the server 5, the server 5 preferably stores only links for the same file.

When another user, for example a file sharer C, selects the link, the file sharer C is able to access the file linked to the link, Can be executed through a connection program (not shown).

The above steps can be performed on the same principle as hyperlinking the web address of the known art.

As a result, by linking only the link to the same file, the same effect as stored can be obtained without storing a file of redundant information in the server 5.

Furthermore, the server 5 can increase the number of links connected to the file corresponding to the same number of file information.

For example, when two or more identical files a1 are stored by a large number of users A, B, C, ..., the server 5 stores the number of users It is possible to increase the number of links and store the information in the memory.

The information stored in the memory is transmitted to the user terminal, and it is possible to confirm whether the file is stored or deleted according to the number of links displayed.

 If the file provider deletes the same file, the other file sharer may no longer be able to use the file. However, if the number of links is displayed, the server 5 does not have the link number of 0 It is possible to continuously store the file a1 without deleting the file even if the user A deletes the file. Of course, information on the file a1 may not be displayed in the file list of the user A that is displayed to other users. As a result, the same file can be completely deleted from the server 5 only when all of the users delete the file.

As a result, there is an advantage that all of the file providers can obtain the same effect as providing the files to the server 5, and the files can not be directly stored in the server, so that the server capacity can be efficiently utilized.

9 is a diagram illustrating a process of storing a shared file a1 according to another embodiment of the present invention in a server of the file sharer B itself.

Referring to FIG. 9, the shared file a1 may be stored in a file server B of the file sharer B.

For example, the sharer B performs a process of selecting and copying by pressing the shared file a1 provided on the screen of the user terminal 1, and then pushing and holding the shared file a1 again on his / To save the file.

Unlike the conventional file transfer method, the above-described storage method can be performed by simply copying and storing a file, so that a data saving effect can be expected. The file can be moved without depending on the shared server 5, and the traffic reduction effect of the server can be expected at the same time.

10 is a diagram illustrating a file sharing system in which a plurality of groups G1 and G2 share a file using a user terminal according to another embodiment of the present invention.

Referring to FIG. 10, when a user A forms a plurality of groups G1, G2,... As needed to provide a file, a plurality of groups can be merged.

The user classification markers 50-1, 50-2, and 50-3 are formed as many as the number of the file sharers B, C, and D, and the files are selected and provided And the merged file sharers B, C, and D can also provide and provide files in the same manner as before merging.

FIG. 11 is a block diagram illustrating the role of a server, a file provider, and a file sharer according to another embodiment of the present invention.

In this block diagram, the role of the server 5 and the role of the file provider are summarized, and the server 5 matches the user's telephone number, and file information is included in the matched list, can do.

Also, when there is a request for file sharing from a user in the user list provided by the server, the file provider may transmit its file to the server 5 and provide the file to the file sharer through the file sharing approval procedure .

In addition, the file sharer can request a file from the file provider and share the file provider's file if the file is approved for sharing. Furthermore, file sharers can also provide files so that multiple users can easily share files in the same way.

12 is a block diagram showing a file sharing system in the user terminal 1 according to another embodiment of the present invention.

The user terminal 1 includes a communication unit 202, a program unit 204, a telephone number management unit 206, a file management unit 208, a file sharing management unit 210 and a display unit 212.

The communication unit 202 can communicate with a server of the file sharing system to transmit and receive signals.

The program unit 204 may execute the application of the file sharing system to automatically transmit the stored phone number information and automatically transmit the selected file among the stored files.

The phone number management unit 206 may collect and store and manage user information stored in the user terminal, such as a phone number of a user and mail. And collects and manages the user list received from the server in response to transmitting the stored phone number and the phone number information to the server.
