Accordingly, the mobile terminal 10 processes the mutual communication with the deletion and authentication center 200 through the communication processing unit 130. [ In addition, the mobile terminal 10 generates various personal information deletion lists by the deletion list generation unit 185. The personal information deletion list is listed by file name, path, size, creation date, and the like.

In order to confirm that the distribution company is an authorized product (mobile terminal) from which personal information has been deleted, a certificate stored in an initial screen or a predetermined area after power on of the corresponding mobile terminal 10 is transmitted to the authentication output unit 165 .

The deletion and authentication center 200 includes a customer server 210, a deletion server 220, an authentication server 230, and a payment server 240. The customer server 210, the deletion server 220, the authentication server 230, and the payment server 240 are connected to each other through a network hub and operate in a centralized server manner.

As shown in FIG. 2, the customer server 210 includes a branch office authentication module 211 for issuing and managing the certification, issuance and management with the branch office to allow access to the branches, data entry, modification and change, Management and management such as year, month, date, agency, processor, time zone, region, statistics and analysis for branch management module (212) And an administrator menu module 213 for the user.

Accordingly, when a customer visits a branch office for new, replacement, or termination related to the mobile terminal, the branch manager (agent or salesperson) makes a description (deletion of personal information deletion instructions) necessary for deleting customer information (personal information) When the customer requests deletion of the personal information, the distribution agent (or the store) accesses the customer server 210 by inputting the ID and the password PW, and after the authentication process, , The serial number, and the distributor (or retailer) of the user and the place.

In this way, the customer server 210 confirms whether the model, the serial number of the customer's mobile terminal, and the input, ID, and password of the user and the distribution agent (or the store)

The deletion server 220 database-stores and analyzes all the personal information corresponding to the deletion check list used in the future in real time. The deletion server 220 also deletes all of the storage devices (main memory, cache memory, USIM chip, SD card, etc.) of the customer mobile terminal 10 in cooperation with the customer server 210, ) Of the personal information.

Therefore, when the deletion processing of the personal information is requested from the client server 210, the deletion server 220 drives the deletion program management unit 180 in the corresponding mobile terminal 10 to delete all personal information And creates a check list in the deletion list generating unit 185 in the mobile terminal 10. At this time, the personal information stored in the main memory, the cache memory, the USIM chip, the SD card, and the application memory is deleted.

Therefore, personal app information data, data existing in cache memory, phone book, photo, video, and document are deleted. In addition, personal information related matters of USIM (carrier) and terminal manufacturer O / S are deleted.

At this time, in order to increase the processing speed, the deletion method can selectively delete a certain value, not delete the entire data. In addition, compression / repetition may be performed 5 times or more, or zero-filling or null-filing may be applied to the data so that the deleted data can not be recovered (however, If not).

Meanwhile, the deletion server 220 identifies the IMEI to the lost mobile terminal and remotely deletes the personal information through the remote connection.

Also, the deletion server 220 checks the deleted personal information and requests the authentication server 230 to issue the digital certificate. In addition, the deletion server 220 stores information deleted from the mobile terminal, and executes a restoration program for processing a request for data restoration.

The authentication server 230 analyzes the PDL to determine the issuance, and issues the encrypted / decrypted digital certificate to the corresponding mobile terminal. It is desirable that the issued digital certificate be processed so as not to be duplicated. If there is a duplication fact, check if the certificate is sent to the authentication center 200 and check whether the duplication is performed by checking the serial number and the certificate of the terminal. If restoration is attempted, it is desirable to destroy the memory area. On the other hand, to the customer making a new basis, the PDL is displayed on the UI (User Interface) to explain the certificate.

In this manner, the authentication server 230 performs certificate examination, issuance and management, and issues a certificate to the corresponding mobile terminal 10 after completing deletion of the personal information.

The payment server 240 calculates the charge of the personal information protection fund, the distribution agent actual expenses, and the operation fee using the payment module. In addition, the payment server 240 calculates and records the tax invoice, the time (year, month, day, time) and the details of the area, agency, and processor and transmits them to the sales point service terminal 15.

The billing can be various payment means such as a prepaid charging type, a postpaid payment type, a giro, a direct debit, a credit card, and a mobile phone payment.

3, the deletion and authentication center 200 includes a client server 210, a deletion server 220, an authentication server 230, and a payment server 240. The NAC server (Network Access Control Server) 300 can be connected.

4, the customer server 210, the deletion server 220, the authentication server 230, and the payment server 240 are connected to each other through a network load balancer 500, It is possible to distribute the load to be applied.

First, when a customer visits (S10) a business office (including a communication service center, an agency, and a retail store) for new, replacement, and termination reasons of the mobile terminal (S10), the clerk at the branch office performs a customer information deletion description (S11) And confirming whether the personal information deletion request in the mobile terminal is requested (S12).

In the deletion request confirmation process, when the customer deletes the personal information, the corresponding branch office accesses the customer server 210 of the deletion and authentication center 200 using the service terminal 15 to obtain an ID and a password PW (S13).

Then, the model and the identification serial number (IMEI) of the requesting customer's mobile terminal are checked to confirm whether the personal information is processed or not (S14).

If the personal information deletion confirmation is made, the personal information in the corresponding mobile terminal 10 is deleted and operated through the deletion server 220 in association with the customer server 210 (S15). At this time, the deletion server 220 analyzes the data of the corresponding mobile terminal and backs up the data.

At this time, the deletion target is data of various memories (main memory, flash memory) of the mobile terminal, application personal data memory, and USIM user data.

At this time, compression can be repeated 5 times or more so that it can not be restored when personal information is deleted. Also, the operating system searches for the start address of each file name in the FAT (file allocation table) so that it can not be restored when deleting the personal information, and a part of the file name is found by null-filling or zero-filling You can increase the purging speed by filling.

Then, when the deletion is completed, the authentication server 230 transmits the certificate to the corresponding mobile terminal 10 (S16).

Then, the certificate is displayed on the mobile terminal 10, and if the display of the certificate is confirmed as failure (S17), the deletion processing is continuously performed.

Then, the payment server 240 transmits the charge information to the branch office through the service terminal 15 (S18).

Then, at the branch office, confirmation of the charge is made through the service terminal 15 and the process ends (S19).

Meanwhile, the certificate issued from the authentication server 230 is further encrypted / decrypted so as not to be copied when stored in the mobile terminal 10.

In addition, there is a step in which the destruction of the internal memory occurs at the time of the external data extraction probe of the certificate stored in the mobile terminal 10.

The deletion server 220 further has a step of immediately restoring the deleted data when there is a request for data restoration in addition to storing the processed information.

Meanwhile, in case of a lost mobile terminal, it is possible to remotely delete and control the personal information by identifying the identification serial number (IMEI).

In addition, when the personal information is deleted, the deletion can be performed by searching for a program or an application program downloaded and installed by a user of the mobile terminal.

In the meantime, the present invention performs the same process as the deletion control flowchart shown in FIG. 5 when the customer requests restoration. At this time, data restoration and billing are requested through signal processing as shown in FIG.
