Image steganography based on LSB using various scanning methods in spatial domain

Abstract

Data security plays a vital role in the field of Information Technology. Cryptography and Steganography methods are widely used to enforce security efficiently. In Spatial Domain, many steganography methods are available such as LSB, PVD etc. These existing methods always suffer from the quality, security trade off. In this paper, we proposed an enhanced LSB method to deal with such tradeoffs. The proposed method achieves the goal by employing variable embedding patterns and the results with optimized PSNR, MSE and entropy values evidently show that the quality and security are well balanced by the proposed method.
