Abstract: Through the analysis of many representative spatial domain watermark algorithms,a new spatial domain digital watermark imbedding algorithm is presented.Encryption with position double secrete key is used,and the method of non plane,imbedding and relevant recovering which based on the character of VHS is adopted in the algorithm.Experiments shows that this algorithm is robust in a series of signal processing operations,and also possesses good transparency.

Key words: digital watermarking, double secret key, non-plane imbedding, human sensing system, relevant recovering
