摘要：Cryptography is the study of mathematicaltechniques related to aspects of information security such asconfidentiality, data integrity, entity authentication, and dataorigin authentication. Steganography is the science ofembedding information into the cover image viz., text, video,and image without causing statistically significant modificationto the cover image. Combining these two techniques either waytogether result to new technique-Metamorphic Cryptography[14]. The data (text, audio, video, images) is transformed intocipher data using a key, concealed into another cover object(audio, video, images) using Steganography converting it into aStegno object, and is finally sent to the receiver. Or the data(text, audio, video, images) is concealed into Cover Objectresulting into Stegno Object, (Steganography)and furtherconverting Stegno Object into Cipher Stegno Object (audio,video, images) using Cryptography, and is finally sent to thereceiver. This proposed both the technique thus achieves doublelayer security to data.
