Provide a New Method to DWT Based Image Steganography Using Fuzzy Logic

In this paper, a method for image steganography using a Fuzzy Logic algorithm, which involves tow inputs and one output in the field of wavelet transform is provided. In which the bits of a message image are hidden into wavelet transform coefficients of image edges by using Fuzzy Logic. Also, shown that in this method that is a non-blind method in frequency domain of wavelet transform, transparency, defiance and data rate is high and acceptable based on the evaluation criteria of SNR, MSE, Similarity and it is easy to implement. If the recovery time is less important, also this algorithm can be combined with encryption algorithm and increased the security of system.
