Abstract

Today the security threats through modern malicious technology, confidential information is at risk such as medical records and banking or financial data and military information where the issue of authentication and authorization has become a critical factor. A solution to this problem is steganography which hides the sensitive information inside a medium (text, image, audio and video). This paper proposes how Least Significant Bit (LSB) insertion has been used to hide secret data in both audio and video with the help of key exchange. Diffie Hellman key exchange is considered to enhance the security aspects and also to generate the key based index for LSB insertion. This proposal can reduce the probability of attacks on secret data.
