HIGH CAPACITY AND SECURITY STEGANOGRAPHY USING DISCRETE WAVELET TRANSFORM

The secure data transmission over internet is achieved using Steganography. In this paper High Capacity and Security Steganography using Discrete wavelet transform (HCSSD) is proposed. The wavelet coefficients of both the cover and payload are fused into single image using embedding strength parameters alpha and beta. The cover and payload are preprocessed to reduce the pixel range to ensure the payload is recovered accurately at the destination. It is observed that the capacity and security is increased with acceptable PSNR in the proposed algorithm compared to the existing algorithms
