Abstract

The invention provides a method for carrying out secret communication by using a word document. The method mainly comprises the following three steps of: manufacturing secret characters by using a True Type character-formation program and generating a secret key; embedding the secret characters into the word document; and extracting the secret characters by using the secret key. According to the method disclosed by the invention, the True Type character-formation program in the conventional general windows operation system, display characters of a window word base and certain functions of word character processing software are designed and integrated so as to realize a function of performing the secret communication by using the word document. The method disclosed by the invention has the advantages of smart conception, simple method, low cost, good commonality and easiness of operation. Therefore, the method can be accessibly used by any operator familiar with windows.

Description

technical field [0001] The invention relates to a secure communication method, in particular to a method for secure communication using a word document. Background technique [0002] With the widespread application of network communication, especially Internet communication, ordinary end users also hope to perform confidential communication on the network, such as: sending a bank card password or sending a private message.
