Image watermarking encryption technology is to convert text information into corresponding binary information and write it into BMP pictures. For example, if the binary code of a text is 01001001, then 0, 1, 0, 0 and 1 are written into eight pixels of BMP pictures respectively, so as to achieve the function of hiding information. Finally, information can be restored by specific programs.
