| Abstract: | An information hiding algorithm based on image DCT domain is introduced. In this algorithm, the secret information is hidden in the DCT matrix of image signal frequency domain ; MATLAB software is used for implementation. Experimental results show that the algorithm is simple, easily implemented, and have characteristics of low distortion, better imperceptibility, safety, goodish robustness and so on. |
