Transmitting Concealed Information With BMP Images

The information concealment technology points out a new direction for the study of information security. The following paper describes the characteristics of the information concealment technology and the general principles of the information concealment transmission through images. It devises a system of information concealment technology based on the equal distribution of different colors for image concealment to meet the needs of the engineering and the particular consumers. The system based on Windows can conceal any files into the BMP images from which we can get back the original information after the transmission on the Internet or carried. It's concealment efficiency reaches about 1/2 ,therefore it solves the problem of transmitting a great deal of information.
