An Information Hidden Method with Chaotic Encryption
Ke Wu · Modern Electronics Technique · 2008
Chaotic sequence is produced Logistic,carring on the encryption to the text information ASCII code,has binary information flow.On image of DCT transform,set coefficients after transform quantized with a quantization table.The binary message after encrypt to embedding the Discrete Cosine Transform(DCT) coefficients of image realizes the information hidden,extracting the secret information is not need the primitive image to participation.The experimental resuls indicate that this method has good hiding and security,is smaller to the image quality influence.
