Abstract:
Steganography is art, a science or a practical attempt that through it some information can be hidden in a cover. The cover can be in audio, image, etc. formats. In this research, a new method for steganography based on lattice vector quantization and DWT is introduced that provides a suitable security level in addition to the hiding possibility as well as complete and accurate extraction of data and makes appropriate level of security by using error correction coding Reed-Solomon (63, 11). The proposed method, using the 3-level lifting wavelet transform and Blocking and then embedding in selected coefficients with using lattice vector quantization, greatly reduces the likelihood of success of mining hidden. The results show that the assessment indicators PSNR, MSE and SSIM better and more appropriate than the same methods and have the previous.
