High Capacity Information Hiding System for Encrypted Text Message Using Pixel Intensity Based LSB Substitution Technique
This paper presents the spatial domain image steganography
based embedding system using different pixel intensities. Here
the efforts have been done to combine cryptography with the
steganography for imparting better security to the proposed
system. Various performance measures like peak signal to noise
ratio, mean square error and the percentage of total pixels used
has been calculated for checking the efficiency and capacity of
the system. Also, steganalysis has been performed to check if the
proposed system is intact to various statistical attacks like
histogram analysis, chi-square analysis and RS analysis.
Keywords: Information hiding, Steganography, Cryptography, Steganalysis.
