Embodiment Construction
[0045] One, design idea of the present invention is as follows:
[0046] 1. Chinese characters exist in the form of binary numbers in computers and networks, and have the same digital characteristics as the pixel values of RGB digital images. Therefore, for each Chinese character, a completely matching binary can be found in the appropriate RGB image. Bit string, and take out the corresponding pixel coordinates to replace the Chinese characters for transmission and storage.
[0047] 2. Select the binary bit string matching the Chinese character in the RGB image by random number, and use the corresponding pixel coordinates to replace the Chinese character, so as to avoid the frequency characteristics of the replacement password and completely solve the attack problem of the frequency statistics analysis of the replacement password .
[0048]3, the Chinese characters are divided into two bytes or more sub-blocks, pixel matching is carried out for each sub-block and the coor...
