For asymmetric split method in the wider use of the color image indicated

this paper proposes a color image representation method based on non-symmetry and anti-packing pattern representation model （NAM for short）.The proposed method transforms color images into the mode of binary value images through decrypting NAM and the method of binary-bit plane decomposition for color images.The color image into a mode of the binary value image.For explosion method devised a new use Singular value decomposition embedded watermark algorithm.The embedded watermark method considered the binary value image.Experiments show that the method is good at representing color images.Based on the above method

this paper puts forward another method of embedding watermarks into the image represented by the above method.Experiments indicate that: the algorithm is simple in operation

with small storage space and effective resistance against different types of attacks;This algorithms also shows strong theoretical and applicability.
