| Abstract: | An improved image hiding technology based on DCT and chaos is presented. We use chaotic system to generate one chaotic sequence which is utilized to encrypt the secret image, and then we use DCT and chaotic sequence to realize the secret image hiding in the host image. Simulation results show that the algorithm has good security and hiding effect. |
