The present invention includes: a terminal having a display and an input unit; and a server providing a service for transmitting and receiving text through the terminal. According to the system, the server and the terminal are connected via the internet a program of the service which transmits and receives text is executed through the terminal, and the terminal may be divided into a first terminal and a second terminal, wherein the first terminal specifies a second terminal receiving text, encrypts the transmitted text, and transmits the outcome to the server. And the server can transmit the encrypted text to the second terminal. A method for encrypting the transmitted text is to select a text box when executing an encryption command through the input unit, and converting the selected text box into encrypted text, wherein the text or information that a user wants to transmit is encrypted in the display of the terminal by selecting a target of the encrypted text transmission and encrypting the text, and when decrypting the encrypted text or information, by the selection and command of the input unit provided at the top end of the display, the information is exchanged by encryption or decryption in real time. |
