Title: Information hiding method
Inventor: TAKAHASHI TOMOAKI
IPC: H04N1/387
Filed: 1991-02-04
Abstract: PURPOSE:To hide other information into picture information without increasing information quantity and deterioration in picture quality by imbeding the other information into low-order bits of a representative value of a picture element when a picture is subjected to block coding. CONSTITUTION:When information to be imbeded is in existence, for example 4-bit information is read and it is imbeded into low-order 2 bits of a mean value of picture elements of two sets. It is stored or sent as a representative value of a block. Moreover, when no information to be imbeded is in existence, a mean value of picture elements of two sets is used as it is as the representative value of the block. In the case of block-coding a picture in this way, the redundancy of the representative value of picture elements in the block is utilized and other information is imbeded in the low-order bits, then the other information is hidden while compressing the entire information quantity.
