A Survey Based on Enhanced the Security of Image Using the Combined Techniques of Steganography and Cryptography

Abstract

Steganography is a science and art of concealing the secret data using a cover medium. Cover medium can be of any type like (Text file, Audio File, Image file, and Video File) we can take any one of them to hide our secret data. Several techniques comes under the Steganography which have different pattern to hide the data. Whereas Cryptography is also an art to provide the security of your secret data by various encryption techniques. Several techniques comes under the Cryptography which have also used different methods to provide the security of data. In this paper, I am survey the combined technique used under Steganography and Cryptography through which we can prove more security to our secret data. Combination of both (Steganography and Cryptography) called metamorphic cryptography which provide a sealed and make more secure your confidential data to decrypt by the attackers.
