The control unit 182 can control the overall operation and function of the search system 10. [

A file search method using an identification number applied to the search system 10 will be described with reference to the accompanying drawings.

3 to 11 are diagrams for explaining a file search method using an identification number according to the present invention. In the following, description of the parts described above may be omitted.

3, the user of the first terminal 200, that is, the file uploader, can transmit information on the first terminal 200 to the server 100 and register the information using the first terminal 200 (S100).

In addition, the user of the first terminal 200 can secure a storage space for storing the file in the first server 100 through a membership subscription method or the like.

Then, in the server 100, the first terminal 200 may assign a personal identification number to the user and store information about the personal identification number (S110). Hereinafter, the personal identification number may be regarded as an identification number corresponding to the user of the first terminal 200.

For example, as in the case of FIG. 4, the personal identification number 1231 is assigned to the A user, the personal identification number 1232 is assigned to the B user, the personal identification number 1233 is assigned to the C user, A personal identification number 1234 may be assigned.

This personal identification number can be set manually by the user. Alternatively, the server 100 may automatically assign the individual identification information corresponding to the user.

Then, the user of the first terminal 200 can transmit / store the information about the file to the server 100 using the first terminal 200 (S120).

Then, the server 100 may allocate a file identification number to the file and store information about the file identification number (S130).

For example, as in the case of Fig. 5, the file identification number is assigned to the authorized certificate file 01, the file identification number is assigned to the home document 02, and the file identification number to 03 is assigned to the contract have.

Thereafter, the second terminal 300 can input a predetermined search formula (S140). In addition, the second terminal 300 may transmit the input search formula to the server 100 (S150).

The search expression may include a personal identification number, a special symbol, and a file identification number. In addition, the special symbol may include at least one of a shop (#) and a star. The special designations applicable in the present invention may not be limited to the shop (#) and the star.

It may be desirable for the special symbol in the search expression to be located between the personal identification number and the file identification number. In this case, the server 100 can more easily distinguish the personal identification number and the file identification number.

In addition, the search formula may be input to a dial input window of the second terminal 300.

6, a search expression composed of a personal identification number 1234, a special symbol # and a file identification number 03 is input to the dial input window DIW of the second terminal 300 can do.

If the call key CK is selected in the state that the search expression is input to the dial input window DIW, the search function can be transmitted to the server 100 without executing the call function (S150). If the special symbol is not used, the second terminal 300 will attempt to call the number entered in the dial input window.

Then, the server 100 may analyze the search formula transmitted by the second terminal 300 (S160).

For example, the server 100 analyzes the identification number located at the front end of the special symbol based on the special symbol, identifies the user (individual), analyzes the identification number located behind the special symbol, .

In addition, the server 100 detects and extracts a file corresponding to the search formula based on the analysis result of the search formula (S170). (File information) of the extracted file to the second terminal 300 (S180).

Then, as in the case of FIG. 7, information about the file corresponding to the search formula may be displayed on the screen of the second terminal 300 (S190).

On the other hand, the order of the personal identification number and the file identification number in the search formula may be changed. For example, as in the case of FIG. 8, it is possible that the file identification number 03, the special symbol #, and the personal identification number 1234 are arranged in order in the search formula.

In the above description, a method of searching for a product by selecting a call key (CK) in a state that a search expression is input in the dial input window DIW has been described, but the present invention is not limited thereto.

For example, as in the case of FIG. 9, it is possible to search for a desired commodity by selecting a search key (LMK) for retrieving a commodity in a state in which a search expression is input to the dial input window DIW.

It is possible to create a search expression using only the personal identification number and the special symbols. In this case, information on the user corresponding to the personal identification number can be displayed on the second terminal 300.

For example, assume that a search expression of 1234 # is input to the dial input window DIW of the second terminal 300, as in the case of FIG. 10 (A). Here, 1234 may be a personal identification number.

In this case, as shown in FIG. 10B, the server 100 may transmit information on the user corresponding to the personal identification number 1234 to the second terminal 300.

For example, information about the files stored in the storage space set by the user corresponding to the personal identification number 1234 is transmitted to the second terminal 300, and this information is displayed on the screen of the second terminal 300 .

In this situation, the user of the second terminal 300 may be able to select and download at least one of the files displayed on the second terminal 300.

The personal identification number may also be set based on information that can identify the user.

For example, as in the case of Fig. 11, the personal identification number may include at least one of a resident registration number, a telephone number, and a social security number.

If the telephone number is used as a personal identification number, a search expression such as 01088888888 # 88 may be used.

If the search expression 01088888888 # 88 is interpreted, it can be interpreted that the file corresponds to the 88th file stored in the storage space corresponding to the user having the telephone number of 01088888888.

12 to 16 are diagrams for explaining a file searching method using a folder identification number. In the following, description of the parts described above may be omitted.

As shown in FIG. 12, the folder stored in the storage space corresponding to the user A (user) may include a contract folder, a business file folder, and a miscellaneous folder.

In addition, contract 1, 2, 3, 4, and 5 contract files can be stored in the contract folder.

As described above, it is possible to allocate at least one folder to the storage space of the A user allocated to the server 100, and to store a predetermined file in at least one folder.

Alternatively, it is also possible that a predetermined file is immediately stored in the storage space of the A user allocated to the server 100. [

A folder identification number can be assigned to each folder. For example, as in the case of Fig. 13, it is possible to assign a folder identification number of 001 to a contract folder, a folder identification number of 002 to a business folder, and a folder identification number of 003 to a miscellaneous folder .

In addition, the folder identification number can be stored in the server 100.

In this case, the search expression may include a personal identification number, a folder identification number, a special symbol, and an eight-mile identification number.

The special symbols may include a first special symbol and a second special symbol to distinguish the personal identification number, the folder identification number, and the file identification number.

For example, as in the case of FIG. 14A, a predetermined user may be able to input a search expression of 1234 # 001 # 03 into the dial input window DIW of the second terminal 300. Such a search expression may include a personal identification number 1234, a first special symbol #, a folder identification number 001, a second special symbol #, and a file identification number 03 in this order.

When the search expression of 1234 # 001 # 03 is analyzed, the file identification number stored in the folder having the folder identification number 001 among the folders stored in the storage space of the server 100 corresponding to the user assigned with the personal identification number 1234 is 03 It can be interpreted as requesting information about a file.

Alternatively, the search formula may be configured in a different order from that of FIG. 14 (A). For example, as shown in FIG. 14B, the search formula includes a file identification number 03, a first special symbol #, a folder identification number 001, a second special symbol #, a personal identification number 1234 ) In order.

As such, the first special symbol in the search expression may be located between the personal identification number and the folder identification number to distinguish the personal identification number and the folder identification number.

The second special symbol may be located between the folder identification number and the file identification number to distinguish the folder identification number from the file identification number.

At least one of the first special symbol and the second special symbol may include at least one of a shop (#) and a star.

For example, as shown in FIG. 15A, the first special symbol may be a shop (#), and the second special symbol may be an asterisk.

Conversely, as shown in FIG. 15B, the first special symbol may be an asterisk and the second special symbol may be a shop (#).

It is possible to create a search expression with a personal identification number and a first special symbol. In this case, information on at least one folder stored in the storage space allocated to the user corresponding to the personal identification number may be displayed on the screen of the second terminal 300.

For example, assume that a search expression of 1234 # is input to the dial input window DIW of the second terminal 300, as in the case of FIG. 16A. Here, 1234 is a personal identification number, and # is a first special symbol.

In this case, as shown in FIG. 16B, information on at least one folder included in the storage space allocated to the user corresponding to the personal identification number 1234 may be displayed on the screen of the second terminal 300.

The user may be able to download the desired file by searching at least one folder displayed on the screen of the second terminal 300. [

17 to 20 are diagrams for explaining a method of using authentication information. In the following, description of the parts described above may be omitted.

Referring to FIG. 17, in step S230, the first terminal 200 can set authentication information after the file identification number is allocated / stored (S130).

Here, the authentication information can be regarded as information for setting security in a predetermined file, a predetermined folder, or an entire storage space allocated to a user. Such authentication information may include at least one of an ID and a password.

That is, setting the authentication information means that the security is set by using the authentication information.

18, the second terminal 300 inputs authentication information together with a search formula (S210) to access a predetermined file stored in the server 100 by the first terminal 200, , And transmits the input search formula and authentication information to the server 100 (S220).

18 can be regarded as a case where the authentication information includes the password having the value '1111'. As described above, the authentication information can be connected to the search formula through a predetermined special symbol.

Then, the server 100 can analyze the search formula and the authentication information (S230).

If the authentication information transmitted from the second terminal 300 matches the authentication information set by the first terminal 200 as a result of the analysis in the server 100, (Transfer) the file of the second terminal 300 to the second terminal 300.

As described above, when the authentication information is used, the user of the first terminal 200 can protect important files.

Meanwhile, the second terminal 300 can be requested to input authentication information from the server 100 in the process of accessing a predetermined file. The following will be described with reference to FIGS. 19 to 20 attached hereto.

19, the server 100 analyzes the search formula transmitted from the second terminal 300 (S160), and determines whether or not security is set in the file to which the second terminal 300 accesses (S300).

If it is determined in step S300 that security is set, the server 100 may request the second terminal 300 to input authentication information (S310).

In this case, an input window for inputting authentication information may be displayed on the screen of the second terminal 300, as in the case of FIG.

When the user of the second terminal 300 inputs the authentication information to access the file set by the first terminal 200 and transmits the authentication information to the server 100 in operation S320, (S330) whether the authentication information input by the user of the second terminal 300 matches the authentication information set by the first terminal 200 user.

As a result of the determination in step S330, if a match is found, a file corresponding to the search formula input by the second terminal 300 is detected (S170), and the detected file can be transmitted to the second terminal 300 (S180 ).

On the other hand, if it is determined as a result of the determination in step S330 that no matching is performed, another predetermined function (Default 1) may be performed (S340). For example, it is possible to transmit to the second terminal 300 notification information indicating that the inputted authentication information is incorrect authentication information.

Figs. 21 to 27 are diagrams for explaining a method of transmitting a file using a search formula. Fig. In the following, description of the parts described above may be omitted.

In the present invention, the first terminal 200 storing a predetermined file in the storage space and securing a storage space in the server 100 transmits the file stored in the storage space to another terminal, for example, the second terminal 300 It is possible.

To this end, as in the case of FIG. 27, the first terminal 200 can set the receiver identification information (S400).

Then, the first terminal 200 can create a search expression and input it (S410).

The receiver identification information may include information corresponding to the terminal to receive a predetermined file from the first terminal 200. [ Hereinafter, for convenience of description, it is assumed that a terminal to receive a predetermined file from the first terminal 200 is a second terminal 300. [

Here, the case where recipient identification information is set in the first terminal 200 before the search formula is described as an example, but the present invention is not limited thereto. For example, in the present invention, it is also possible to set the receiver identification information after creating the search formula first.

After inputting the search formula, the first terminal 200 may transmit a combination formula including the input search formula and the receiver identification information to the server 100 (S420). Here, in the combination formula of the search formula and the receiver identification information, a special symbol for distinguishing the receiver can be placed between the search expression and the receiver identification information.

Then, the server 100 receives the search formula and the receiver identification information from the first terminal 200, and analyzes the received search formula and the receiver identification information (S430).

The recipient identification information corresponding to the recipient may include the telephone number of the terminal to receive a predetermined file from the first terminal 200. [

For example, as in the case of FIG. 22, a search expression can be constituted by a personal identification number 1234, a folder identification number 001, a file identification number 03 and a special symbol #. In addition, recipient identification information (01099999999) can be combined using another special symbol (#) in the search expression.

When the search expression and the receiver identification information in FIG. 22 are analyzed, the file No. 03 included in the folder having the folder identification number 001 in the storage space allocated with the personal identification number 1234 is transmitted to the terminal having the telephone number of 010-9999-9999 .

Here, the storage space to which the personal identification number 1234 is allocated may be a storage space corresponding to the first terminal 200.

Alternatively, the recipient identification information may include the email address of the user receiving the file.

For example, as in the case of FIG. 23, a retrieval expression may be composed of a personal identification number 1234, a folder identification number 001, a file identification number 03 and a special symbol # The symbol (#) can be used to link recipient identification information (ChunkyLover53@AOL.com) containing the email address.

By interpreting the search formula and recipient identification information in FIG. 23, it can be interpreted that the file 03 included in the folder having the folder identification number 001 in the storage space to which the personal identification number 1234 is allocated is transmitted to ChunkyLover53@AOL.com.

Since the recipient identification information may include an email address as well as a telephone number, it may be desirable to be referred to as 'identification information' rather than 'identification number'.

The server 100 may detect a file desired to be transmitted by the first terminal 200 based on the information obtained by analyzing the search formula and the receiver identification information at step S170 and may transmit the detected file to the second terminal 300 (S440).

Then, the second terminal 300 can display the received predetermined file on the screen (S450).

On the other hand, when combining the retrieval expression and the recipient identification information, it is possible to change the special character to facilitate differentiation between the retrieval expression and the recipient identification information.

A special symbol located between the search expression and the receiver identification information is called a reception symbol, and a special symbol located in the search expression is a search symbol.

Here, it may be preferable that the reception symbol and the search symbol are different from each other.

For example, as in the case of Fig. 24, the retrieval expression is expressed by a personal identification number 1234, a first special symbol #, a folder identification number 001, a second special symbol #, and a file identification number 03 Lt; / RTI > Here, the first special symbol (#) and the second special symbol (#) may be a search symbol (500).

Further, in the combination formula in which the retrieval expression 1234 # 001 # 03 and the recipient identification information 01099999999 are combined, the reception symbol (*, 510) can be used to connect the retrieval expression and the receiver identification information.

Here, the first special symbol (#) and the second special symbol (#), which are search symbols, are the same and may be different from the received symbol (*, 510).

As described above, if the reception symbol 510 and the search symbol 500 are set differently, an error can be prevented from occurring when the personal identification number is set to a telephone number or the like.

For example, assume that the personal identification number is set to the telephone number (01088888888) and the recipient identification information is also set to the predetermined telephone number (01099999999), as in the case of Fig.

Here, if the search symbols (#, 500) included in the search formula and the receive symbols (*, 510) connecting the search formula and the receiver identification information are set differently, it is possible to prevent a predetermined file from being transmitted erroneously.

As in the case of FIG. 26, even if the receiver identification information is located earlier than the search formula, it is possible to prevent the occurrence of errors by setting the search symbols (#, 500) and the received symbols (*, 510) differently.

When a predetermined file selected by the first terminal 200 is transmitted to the second terminal 300, notification information for notifying the reception of the file may be displayed on the screen of the second terminal 300 have.

In addition, the second terminal 300 can determine whether to accept the received file.

For example, if the second terminal 300 does not trust the sender of the file, the user may not accept the file by selecting the 'No' menu.

In this case, the second terminal 300 may not perform decoding even if a packet of a predetermined file is received from the server 100.

As described above, it is to be understood that the technical structure of the present invention can be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.

It should be understood, therefore, that the embodiments described above are to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than the foregoing description, And all changes or modifications derived from equivalents thereof should be construed as being included within the scope of the present invention.
