A loss less and visible watermarking algorithm is proposed. The carrier image can restored loss less. The exterior appearance is like to mark by use of image addition technique. The visible watermarking can replace the mark. Because of self-recovery, it offers the original data to the validated user. The Hash function of RH arithmetic operator is(More)
