A Novel Comprehensive Watermarking Scheme for Color Images

Algorithm 3

Embedding fragile watermark.

(1)	Step 1: divide the color image which is embedded robust watermarks and into nonoverlapping blocks of 16 × 16.
(2)	Step 2: use the layer R and the layer G to generate hash sequence.
(3)	Step 3: embed the watermark sequence in the layer B using the LSB embedding method [20].
(4)  Step 4: repeat steps 2–3 until all the blocks are processed.
