Abstract

PURPOSE: A method for protecting the personal information of a lost portable terminal is provided to protect the personal information of a portable terminal by controlling the deletion, download, locking and backup of personal information in a remote place by a user's request. CONSTITUTION: In a case that a control request for a lost portable terminal is generated and the portable terminal is in a power-on state, a mobile communication network finds out the location of the terminal and requests the terminal to send a response. If a response is transmitted, the mobile communication network sends a control command and receives a response indicating that the personal information of the lost terminal has been controlled. When a backup request is generated from the user, personal information data are received. After receiving the response, the mobile communication network writes information indicating that the personal information of the lost terminal has been controlled or the personal information data in a personal communication service company database.

Description

Privacy information protect method for a lost mobile terminal

The present invention relates to the security of all personal mobile terminals of personal AMPS, IS95, PDA, IMT-2000, GSM, notebook computer, and more specifically, the user remotely stores user information stored in the personal mobile terminal through security settings. The present invention relates to a security method of a personal mobile terminal that automatically controls backup, information download, information lock, and information deletion.

As the number of users of personal portable terminals has increased rapidly, various economic activities utilizing personal portable terminals have been activated. The damage to the leakage of personal information behind it cannot be overlooked.

Conventional personal mobile terminal security level is almost only to protect the information held by the service provider. Personal mobile devices store extremely personal information such as personal phone books, messages, and schedules. In the event of losing a portable terminal storing such personal information, the information is completely disclosed to a third party. As a way to prevent the leakage of personal information, the terminal itself is given a password, and if the password is applied, if you don't know the password, you may have some difficulty in reading the information. But this level of security is too vulnerable. Such security is inherently invaded when personal information is stored in a personal portable terminal. Increasing the length of the password is simply an increase in the number of attempts. Complete security is to delete personal information stored in personal mobile terminal or to protect personal information only when personal information cannot be viewed on personal mobile terminal.

The present invention overcomes the above limitations of the security level of the conventional personal portable terminal, and at the request of the user remotely delete personal information of the terminal, terminal personal information download, personal information lock, personal information as a control of personal information backup We want to provide a way to protect your information.

1 is a remote personal information control flowchart in a call processing step of a personal portable terminal to carry out the present invention.

FIG. 2 is a flowchart for remote personal information control in a mobile communication network implementing part of FIG. 1 (11).

FIG. 3 is a flow chart of a personal portable terminal information control in the personal portable terminal implementing part 1 (12).

In order to achieve the above object of the present invention, a mobile phone service company having a "security application step and personal portable terminal information" for applying for a control service of information protection personal information remote backup, personal information download, personal information lock, and personal information deletion The "security setting step" of the present invention provides a personal portable terminal security method comprising an environmental grasping step of grasping the current personal portable terminal status, and an information control step of controlling personal information of the personal portable terminal. The control raised in the present invention includes a control for backing up data stored in a personal portable terminal remotely, a deletion control for deleting personal data stored in the portable terminal remotely, and a download control for receiving personal information data in the deleted personal portable terminal. In the present invention, a lock control is provided to prevent the viewing of personal information on a terminal that is not a secret key method.

The present invention as described above consists of a process of controlling the loss of the user who lost the personal portable terminal, the personal information control settings of the mobile phone service provider and the remote personal portable terminal information.

The security of the personal mobile terminal is a request for a control item selected by the user during the control of remote personal backup, personal information download, personal information lock, and personal information deletion at the request of an authenticated user who has lost the personal mobile terminal. Are recorded on the service computer. After the information control request is stored in the service company's computer, if there is a certain time or any change, the request for control of personal information is confirmed after checking whether there is an information control request of the personal portable terminal in the existing step of registering the location information of the personal portable terminal. If there is a personal information control command is sent to the personal terminal, the personal information is controlled through the process of receiving a response or personal information from the personal portable terminal.

The process of checking whether the personal information control is set in the location registration step and, if it is set, sends a request to control the information to the personal portable terminal and receives a response indicating that the personal information is controlled.

There are two cases of a method for controlling personal portable terminal information. The first is when there is a control request when the personal portable terminal to be controlled is in the power-on state. In this case, the mobile communication network first finds the location of the personal mobile terminal and then requests a response from the found personal information. If there is a response, the control command is sent, and then a response or personal information data is received from the personal portable terminal. After receiving the response, the control information and the personal data are recorded in the cellular service provider database. When receiving personal information data, personal information data is received when a backup request is made.

The second case is a case where a control request comes to access the first base station after the mobile terminal to be controlled is moved to a cell coverage in a region other than the power-off state and the service. First, when a mobile terminal is powered on for the first time while the mobile terminal is in the power-off state, and the terminal that moves to the service area registers the first location, it transmits a control command to the personal mobile terminal with control in the process of registering the location. If the control command is a download, send backed up personal information. If there is a response to this transmission, the information is controlled and if it is set as a personal information backup, personal information data is also received and recorded in the cellular service provider database.

According to the present invention, in order to protect the personal information stored in the personal portable terminal by the user due to loss or for some reason, the information is controlled by remote control such as personal information backup, personal information download, personal information lock, and personal information deletion. I can protect it.
