MSE and MAE Based Investigation of Modified LSB Approach

Abstract

Modified LSB approach is one of the many techniques to conceal data. Message is hidden in R, G and B components of pixels of a colored host image in Modified manner. Firstly a message bit is inserted on R-component�s LSB of 1st pixel then on G-component�s LSB of 2nd pixel and further on B-component�s LSB of 3rd pixel and so on. In this manner data of different sizes 4KB, 8KB and 16KB are inserted and result is analyzed based on MAE and MSE based parameters.
