Experimental Study of the Hidden Image Based on DCT Transform
WU Qi
Abstract：This paper introduced the digital image hidden technique and the importance of the digital image hidden technique in the lives and works at first.Then it introduced common hidden image algorithms and proposed a kind of the digital image hidden algorithm which based on the DCT transformation and gives out it’s essential theorem to carry out. By making the algorithm do some resisting attack tests,such as imcrop,rotate and so on,it arrived at the experiment results and then drew the conclusion after analyzed the experiment results.
