At this time, the mobile terminal 100 registers the protected phone number selected for the information security among the phone numbers of the stored contacts in the information security server 200 through the information security app installed in the mobile terminal 100, The mobile terminal 100 stores the matching key generated in correspondence with the protected phone number registered in the mobile terminal 100. [ Meanwhile, the portable terminal 100 registers the corresponding protected telephone number in the information security server 200, and deletes the corresponding protected telephone number in the portable terminal 100 when storing the corresponding matching key.

Accordingly, in the portable terminal 100, the contact name and the matching key corresponding to the protected telephone number are stored. The matching key is an encrypted key for matching with the protected telephone number registered in the information security server 200, The protected telephone number registered in the information security server 200 can not be deduced or deduced.

When requesting the information security service through the information security server 200, the portable terminal 100 must install the information security application, which is an application provided by the information security server 200, in the mobile terminal 100, 100 registers the telephone number to be protected through the installed information security app in the information security server 200.

When the mobile terminal 100 originates or receives a call to a protected phone number registered in the information security server 200, the information security app suspends the origination or incoming call connection and transmits the originating phone number or the incoming phone number as information The security server 200 checks whether the protected telephone number corresponds to the protected telephone number. If the protected telephone number corresponds to the protected telephone number, the protected telephone number is not outputted on the outgoing call screen or the incoming call screen, and then the call connection is performed.

4 is a block diagram illustrating an information security server for protecting personal information of a portable terminal according to the present invention. 4, the information security server 200 includes an application processing unit 210 for transmitting and receiving data from an information security app installed in the mobile terminal 100 (hereinafter referred to as the mobile terminal 100) A key matching unit 220 for extracting a protection phone number corresponding to a matching key transmitted from the mobile terminal 100, a database unit 230 for storing a matching key and a corresponding protection phone number, A key generation unit 250 for registering a protection phone number to be protected and generating a matching key corresponding to the protection phone number, And an image generating unit 260 for generating an icon in the form of an image or text.

The application processing unit 210 transmits / receives data to / from the portable terminal 100 according to registration, origination or reception of a protected telephone number.

When selecting a phone number to be protected through the information security service among the phone numbers stored in the mobile terminal 100 and transmitting the selected phone number to the information security server 200, the application processing unit 210 uses the protected phone number and unique key to be transmitted And performs the registration procedure.

In this case, the inherent key is an authentication key for authenticating the portable terminal 100 using the information security service, and the application processing unit 210 performs authentication of the portable terminal 100 using the inherent key of the received portable terminal 100 Can be performed.

The application processing unit 210 receives the matching key and unique key transmitted from the mobile terminal 100 at the time of calling, authenticates the mobile terminal 100 using the received unique key, The key matching unit 220 transmits the received matching key to the key matching unit 220.

If there is an originating request from the portable terminal 100, the key matching unit 220 determines whether the matching key transmitted according to the originating request is valid, and transmits the protected telephone number corresponding to the determined matching key to the database unit 230 .

In this case, the validity of the matching key is determined by checking whether the received matching key is a matching key corresponding to the registered protected telephone number according to the information security service request of the corresponding mobile terminal 100. If the validity of the matching key is confirmed, Extracts the protected telephone number corresponding to the matching key from the database unit 230, and transmits the matching key and the protected telephone number to the key exchange unit 240.

When the portable terminal 100 transmits an outgoing telephone number to the information security server 200 in response to a telephone call, the key matching unit 220 receives the transmitted outgoing telephone number, Whether or not the information is included in the protected telephone number according to the information security service of the terminal 100 is determined through comparison with the protected telephone number stored in the database.

If the originating telephone number is included in the protected telephone number, the key matching unit 220 extracts the matching key corresponding to the protected telephone number, which is the calling telephone number, from the database unit 230, And transmits the telephone number to the key exchange unit 240.

On the other hand, if the originating phone number does not match the protected phone number stored in the database, the key matching unit 220 determines that the corresponding source phone number does not correspond to the protected phone number to be protected, generates an error message, The portable terminal 100 can transmit the calling phone number and the contact name to the incoming call screen by performing the call connection to the portable terminal 100 through the processing unit 210. [

That is, when the originating phone number is not a protected phone number to be protected, there is no corresponding key. Therefore, when the mobile terminal 100 receives an error message from the information security server 200, So as to perform a general telephone call. Accordingly, when the mobile terminal 100 performs the incoming call by the originating phone number, the portable terminal 100 outputs the originated phone number and the corresponding contact name to the incoming call screen.

The database unit 230 stores the protected telephone number, which is a telephone number to be protected, in the portable terminal 100 requesting the information security service, and stores a matching key corresponding to the protected telephone number. It is preferable that the protected telephone number and the matching key are stored in pairs, respectively, but are separately stored so that they are not known to match each other.

Also, the database unit 230 may store an icon corresponding to the matching key generated by the key generating unit 250 together.

The key exchanging unit 240 exchanges the matching key and the protection phone number received from the key matching unit 220 in response to the call of the portable terminal 100 and transmits the exchanged protected phone number to the application processing unit 210 To the portable terminal (100). When the transmitted protected phone number is received, the portable terminal 100 releases the hold and performs call origination using the received protected phone number, and the call originating screen displays a matching key and a corresponding contact name Output.

The key exchanging unit 240 exchanges the matching key with the protected phone number received from the key matching unit 220 in response to the incoming call of the portable terminal 100 and transmits the matching key to the application processing unit 210 To the portable terminal (100). Accordingly, when the matching key is received, the portable terminal 100 can release the hold of the incoming call and output the corresponding matching key and the corresponding contact name on the call incoming screen to perform the call incoming.

The key generation unit 250 generates a matching key corresponding to the transmitted protected phone number when transmitting the protected phone number, which is a phone number to be protected, to use the information security service in the mobile terminal 100. [ The matching key is preferably generated with an encryption key that can identify the protected phone number.

At this time, it is preferable that the matching key generated by the encryption key is generated so that the protected telephone number can not be extracted or deduced even when it is decoded by hacking or the like. Accordingly, the protected telephone number and the corresponding matching key correspond to one-to-one correspondence, and can be generated corresponding to each protected telephone number without overlapping. The generated matching key and the transmitted protected telephone number are stored in the database unit 230 .

The image generating unit 260 selectively generates an icon according to the matching key generated by the key generating unit 250. When an icon is transmitted to the portable terminal 100 together with a matching key and stored, the portable terminal 100 is provided with a contact name, a matching key or an icon corresponding to the protected phone number The protected telephone number to be protected is deleted and not output.

On the other hand, if the icon is not generated after generating the matching key corresponding to the specific protected telephone number, the icon is selectively generated, and only the corresponding matching key is transmitted to the mobile terminal 100. Also, the matching key transmitted to the portable terminal 100 is preferably output to the portable terminal 100, but may not be displayed on the screen.

5 is a flowchart for registering personal information of the portable terminal in the information security server according to the present invention. As shown in FIG. 5, the mobile terminal 100 executes the information security app and performs login (S110).

Thereafter, a telephone number for receiving the information security service is selected by the user (S120). One or more protected telephone numbers are selected to receive the information security service, and a plurality of protected telephone numbers are generated as a list of protected telephone numbers.

The information security app of the mobile terminal 100 transmits the protected phone number or protected phone number list selected to receive the information security service and the unique key of the information security app to the information security server 300 (S130). The unique key is used for authenticating the portable terminal 100 requesting the information security service in the information security server 300 and used for login.

The application processing unit 210 of the information security server 200 authenticates the wireless terminal through the received unique key and transmits the received phone number or each phone number included in the protected phone number list to the key generation unit 250 And applies security (S140).

Applying security to the protected telephone number generates a matching key corresponding to the protected telephone number, and may generate an icon for displaying the corresponding matching key through the image generating unit 260 as needed. Icons can be created in the form of images or text, but they are not required to be created.

The key generation unit 250 generates a matching key corresponding to the protected telephone number or the protected telephone number list, and transmits each generated protected key number and each protected telephone number included in the protected telephone number or the protected telephone number list to the database unit 230 (S150).

The protection phone number and the matching key stored in the database unit 230 are separately stored so that they do not match each other, and a matching key or a protected telephone number is extracted according to a call origination or an incoming call.

The application processing unit 210, when the generation of the matching key for the protected telephone number is completed through the key generating unit 250 and is stored in the database unit 230, the one or more matching Key to the portable terminal 100 (S160).

Upon receiving the matching key from the application processing unit 210 of the information security server 200, the information security app of the mobile terminal 100 changes the protected phone number to be protected to a matching key (S170).

That is, the protected telephone number is deleted from the portable terminal 100 and is not permanently restored to the portable terminal 100 itself, and the matching key is stored in the deleted protected telephone number.

On the other hand, when icons corresponding to the matching key are generated and transmitted together, it is preferable that the corresponding icons are stored together in the contacts.
