Abstract :
In this paper, a watermark scheme based on imbedding watermark in the residual between the two successive frames. The watermark is imbedded in the high-frequency coefficients of the obtained DCT of the residual The scheme can resist the attack of compression coding effectively. The simulations show that the scheme has good performances to resist Gauss attack, pepper and salt attack, cutting and compression attack.
