CRITICAL ENCRYPTION WITH STEGANOGRAPHY
Gondi Bhargavesh · 2014
Steganography is the art of hiding information and an effort to conceal the existence of the embedded information. Steganography is often confused with cryptography because the both are used for used to protect important information. It serves as a better way of securing message than cryptography which only conceals the content of the message not the existence of the message. In Steganography original message is being hidden within a carrier such that the changes so occurred in the carrier are not observable. On the other hand Cryptography basically means art of protecting information by converting it into unreadable format. Cryptography and Steganography are present in different domains of network security and often used as separate techniques to provide confidentiality and security of data. So in this paper we discuss how images can be used as a carrier for protect- ing the data and how encryption can be applied on the data hidden in the Stego image. This paper will take in-depth look at this technology by introducing readers to various concepts of Steganography and Cryptography, a brief history of the above concepts and the technique in which both of the concepts can be applied for achieving confidentiality and authentication of the data.
