Abstract: Cryptography and steganography are the two research areas which are popular for data confidentiality, data hiding respectively. Steganography hides the data in various multimedia cover files like image, audio and video. This paper handles images for steganography, which have high redundant pixels. In this paper, Lease Significant Bit (LSB) method hides the secret message bits in least significant bits of each pixel. The performance metrics MSE and PSNR are used to check the strength of the proposed algorithm. The proposed algorithm also checks payload capacity, image quality and security of the confidential data by applying cryptography and steganography algorithm and various parameters.
Keywords: Pixel, MSE, PSNR, LSB, distortion
Scope of the Article: Cryptography and Applied Mathematics
