Abstract

A method and system for providing a personal information control service for a mobile communication terminal are disclosed. The method for providing personal information control service for a mobile communication terminal includes: transmitting, by a service client, a loss registration control command to a service operating system; notifying, by the service operating system, that a mobile communication terminal of a user has been lost by using one of a method of transmitting a particular form of loss control message to the user mobile communication terminal and a method of originating a call using a particular origination number to the user mobile communication terminal in response to the loss registration control command; and activating, by a control agent provided in the user mobile communication terminal, a service function of the control agent to protect personal information of the mobile communication terminal based on the notification about the loss. When the mobile communication terminal is lost, it can be controlled by transmitting a particular form of message or originating a call using a particular origination number.
