Description

How to manage user information through short message in mobile terminal {METHOD FOR MANAGEMENT USER INFORMAION USING SHORT MESSAGE SERVICE IN MOBILE PHONE}

The present invention relates to a mobile communication terminal, and more particularly, to a method of initializing user information or performing a locking function using a short message.

In recent years, the spread of mobile communication terminals has been made rapidly, and the performance of the information processing has also developed, and as a portable information processing device for processing data of users in addition to functions as a telephone, the role has increased. The information processing functions implemented in the recent mobile communication terminals include a phone book function, an address book function, a schedule management function, a simple memo function, and the like, so that the user can conveniently use the mobile communication terminal. In addition, these various convenience functions are basically added to not only mobile communication terminals but also communication terminals that can be carried by a user such as PDAs (Personal Digital Assistants). However, most of these convenience functions relate to the user's personal information. For example, phone book information, personal schedule information, call history information, and the like in the mobile communication terminal are personal information unique to the user.

Therefore, if a mobile communication terminal storing such personal information is lost, it is likely that the other party is stolen by another person. In order to prevent this, conventionally, a mobile communication terminal allows a user to set a password to restrict unauthorized use of others. However, if the mobile communication terminal is lost in the state in which the usage restriction function is not set, the user calls the customer center or the like to apply for call termination or termination to prevent unauthorized use of the mobile communication terminal. However, this method can prevent unauthorized use of the mobile communication terminal by another person, but it is difficult to protect user personal information stored in the mobile communication terminal. As an example of a technique for solving such a problem, there is a "mobile communication terminal having a locking function using a single message and a method thereof" of Korean Patent Application No. 2001-0078063. In the technology disclosed herein, the mobile communication terminal includes a key input unit. Through receiving and saving the lock function unlock password, the user receives and stores a string to perform the lock function from the key input unit and receives and stores the type of lock function. If the user transmits a short message for executing the lock function, the mobile communication terminal receives the short message and analyzes the received short message to perform the lock function when the lock function execution string exists. This method can prevent unauthorized use of the mobile communication terminal by others, and can protect user personal information stored in the mobile communication terminal.

However, according to the related art, the set lock function of the mobile communication terminal is executed according to whether the password in the short message transmitted from the user matches the password set in the short message transmitted from the user while the password and the lock function are set in advance by the user. .

As described above, even if a short message for remote control setting is remotely transmitted to a lost mobile communication terminal when the mobile communication terminal is lost, the short message is transmitted only when the password and lock function are set in advance by the user. We could analyze and execute the lock function. However, due to an unexpected situation, for example, when the lock function is released because any input number matches the password, user information stored in the mobile communication terminal may be leaked. In addition, in preparing a short message for executing a lock function of a lost mobile communication terminal, it may not be easy to allow the middle-aged to set a lock function through a user interface in a state in which the middle-aged short message utilization is not high.

Accordingly, an object of the present invention is to solve the above problems, without the need to create a short message for the lock function by the user when the lock function is not set in advance by the user when the mobile communication terminal is lost, The present invention provides a method of managing user information through a short message in a mobile communication terminal capable of performing a lock function through a service provider service center.

In addition, another object of the present invention is to delete all the user information when the mobile communication terminal is lost, can eliminate the concern that the personal information is exposed to others, and also through the short message to the user information of the mobile communication terminal The present invention provides a method for managing user information through a short message in a mobile communication terminal capable of initializing and preventing exposure of user information.

The present invention for achieving the above object is a process of analyzing the content of the received short message upon receiving the short message, determining whether there is a code value set in the teleservice ID field in the short message, the set tele When the code value of the service ID field is a code value indicating that the user information is initialized, deleting the user information stored in the memory unit, and indicating that the code value of the set teleservice ID field is the data indicating the automatic lock In the case of a code value, a lock function is performed.
