Abstract :
In this paper a mixed blind algorithm of watermarking based on frequency domain is offered, which combines discrete wavelet transformation and discrete cosine transformation to solve the problem of the collection of watermark when the distortion occurs with the change of the external shape of the picture. The experimental findings indicate that the algorithm has the features of watermark.
