Suitability of LSB Substitution based Steganography for Digital Images: A Study

Dr. Aruna Kumar Mishra, Er. Purabee Purnasha Mishra

Abstract :

Advancement in processing speed of computers and the penetration of oad band gave rise to different sophisticated techniques of cryptography. Presently as the analog images are almost obsolete there is a need for fresh look into the digital image steganography as a way of embedding data. It has wide applications in present Internet age such as secure transmission of confidential data, maintain copyright etc. But the major question is that which technique to be used without changing the quality of the images or least affecting the quality of images. This paper focuses on the suitability of Least Significant Bit(LSB) Substitution method as a technique of Steganography. In this study the Digital Images with date emebeded in it and the digital images without data are shown to the respondents to find out if there is any change in the quality of the images and whether the respondents can differentiate the images.
