Study on Encryption and Decryption Algorithm and its Matlab Realization
The paper studies the process of how to encrypt images through Logistic chaotic model, how to use DCT transform to hide the encrytion image in the carrier image and how to restore the images through DCT inverse transformation, analyzes the peak signal-to-noise ratio and realizes the whole process through Matlab.
