       The present invention relates to a method for preventing the leakage of personal messages in a mobile communication terminal, and more particularly, to a mobile communication terminal that receives a message including security information set by a transmitter and checks a message when a password corresponding to the security information is input. In a private secret message protection method.

       The mobile communication terminal can perform voice and data communication regardless of time and place, and is further provided with a function of receiving information necessary for life in text. For example, mobile communication service providers use the short message service (SMS) that enables simple message transmission to provide news service, event information, weather information, sports information, stock information, exchange rate information, traffic information, etc. To provide. Short Message Service (SMS) refers to a two-way service that can send and receive short text messages regardless of whether or not a mobile communication terminal. The service is intended to receive messages via public telephone networks, data communication networks or the Internet when a mobile communication service subscriber sends a short sentence of about 80 bytes to the same mobile communication service subscriber or another mobile communication service subscriber. The short message is received or sent, and the received or sent short message is stored and managed in the inbox or the outbox. However, the short message stored in the message inbox or the sender has a problem in that the contents of the message can be viewed even by the person other than the user, thereby violating the privacy of the user. However, the conventional short message management method using a privacy protection function cannot manage individual messages separately, and when a user does not want to show a specific message to another person, when a user sets a short message, there is a problem of limiting unintended messages by setting. . Therefore, in consideration of such a problem, the short message stored in the terminal is locked by granting a password according to the contents. The locked message is disclosed in Korean Patent Laid-Open Publication No. 1-2004-0085735 as a method of releasing the lock by a password. In another method, as disclosed in Korean Patent Laid-Open Publication No. 10-2004-23089, a message requiring information protection by message type or phone number is notified to the user only, and the message content can be confirmed by inputting a password. Korean Patent Laid-Open Publication No. 10-2003-47094 refers to a value set in this variable when a short message is received that includes a variable for determining whether a short message is displayed or not, and whether to display the message directly according to the result. Only the display and contents can be confirmed by entering the password. All of the above conventional methods are inconvenient to remember the password, that is, the password, i.e., the password, i.e., the password, i.e., the password, i.e., the password, i.e., the password, i.e., the password, i.e., the password, i.e. the password, i.e. the password, i.e. There is no way of transmitting with care in consideration of security in advance.

       Therefore, an object of the present invention can be transmitted in consideration of security when transmitting a message, the message confirmation is to provide a method for protecting the leakage of the message from others by using the personal information of the recipient who is not specifically determined as a password.

       It is another object of the present invention to provide a method of adding a security information to a message to distinguish a general message from a security message when writing a document, and checking a message by inputting a password according to a message required from the security information when receiving the document. .

It is still another object of the present invention to provide a method for protecting a secret message without having to remember the password separately because the password requested by the sender uses information already recorded in the predetermined memory or phone book of the receiver. .

       The present invention for performing the above object is a process of setting a security mode for the message to be sent, the process of setting the security information to be loaded on the message at the sender in the process, and the security information set in the process the head of the message Comprising a process of creating a message and sending it, the request for input of the corresponding password in accordance with the security information in the received message, and the process of checking the message by inputting the required password in the process .

       Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, specific details such as specific components are shown, which are provided to help a more general understanding of the present invention, and it is understood that these specific details may be modified or changed within the scope of the present invention.
