Abstract

A system and a method for encoding and transmitting an inputted character in a terminal are provided to prevent transmitted/received characters from being exposed to other persons by encoding a text through a character conversion program, transmitting the encoded text through a mobile communication network, receiving the encoded text, and decoding it into the original text again. The user of a mobile terminal inputs characters by using a character input button part(s100). The user pushes a text conversion button to convert the inputted characters and drives a character conversion program(s110). At this moment, the user inputs a password and maintains a locking state(s110a). If the inputted character is converted as the character conversion program is executed(s120), the user pushes the SEND button and transmits the converted character to the receiving side through a mobile communication network(s130). The user of the receiving-side mobile terminal receives the converted character through the mobile communication network(s140). The receiving-side user pushes a character conversion button and executes a character conversion program(s150). At the same time, the receiving-side user pushes a password and releases the locking state(s150a). The received character is converted into the original character as the character conversion program is executed(s160).
