    Abstract :

    Steganography is one of the most popular security mechanism that is widely adopted in today’s world for secure data communication in multiple domains. Steganography refers to ‘concealed writing’ where the goal is to hide the existence of data in transit in a cover medium (here image is considered) thereby ensuring data privacy. Three different steganographic schemes; namely Simple Least Significant Bit Substitution (SLSBS), Variable Least Significant Bit Substitution (VLSBS) and Most Significant Bit- Least Significant Bit (MSB-LSB) Substitution schemes are analyzed in this work. A detailed literature survey is conducted in the steganography domain, to investigate some of the widely adopted popular steganographic metrics employed nowadays. Some such metrics like Peak Signal to Noise Ratio (PSNR), Mean Square Error (MSE) , Normalized Cross Correlation (NCC), Normalized Absolute Error (NAE), Average Difference (AD), Maximum Difference (MD), Structural Content (SC) etc have been computed and investigated for the above mentioned steganographic schemes for the purpose of comparative performance analysis.
