- Abstract
- The paper studies the arithmetic of encryption and decrytion based on Logistic, the arithemtic of hiding and restoring encripted pictures based on DCT. Meanwhile, the author uses the two arithemtics to encript and hide images to get safer carrier images, analyzes the peak signal-to-noise ratio and realizes the whole process through Matlab.
