Description: In this paper, VC technology LSB algorithm of digital image watermark embedding and extraction of key stream cipher symmetric key algorithm. Through the design can be easily embedded in the host image in a large number of digital information, higher capacity and preferably not visible in the lowest bit is embedded in the watermark embedding capacity can be realized. The LSB algorithm advantage of simple algorithm, the calculation speed is relatively fast. But a variety of operations such as image compression, shear, etc., will enable the reliability of the algorithm is affected, there may be increased by noise or lossy compression to eliminate the watermark, i.e. poor robustness.
