Review Paper on LSB Based Stegnography to Enhance Image Security IJTSRD
Steganography is the technique of hiding a secret message or information in a cover message like an image, text or sound in such a way that only the desired or intended recipient knows about the existence of the secret data. It can be defined as the study of invisible communication which usually deals with the technique of hiding the existence of the secret message. The hidden message may be in the form of text, image, audio and video etc. An image after inserting the secret message into it by using a stegokey is known as a stego image. Nowadays steganography is important due to an exponential growth in secret communication by potential computer users over the internet. In this paper we have analyzed the various steganography techniques and observed that the security of the secret message can be enhanced by random selection of the pixels for substitution in LSB steganography. Further the error metrics PSNR Peak Signal to Noise Ratio should be high and MSE Mean Square Error should be low indicating good quality re construction.
