Cryptography is the study of mathematical techniques related to aspects of information security such as confidentiality, data integrity, entity authentication, and data origin authentication. Steganography is the science of embedding information into the cover image viz., text, video, and image without causing statistically significant modification to the cover image. Combining these two techniques either way together result to new technique-Metamorphic Cryptography (14). The data (text, audio, video, images) is transformed into cipher data using a key, concealed into another cover object (audio, video, images) using Steganography converting it into a Stegno object, and is finally sent to the receiver. Or the data (text, audio, video, images) is concealed into Cover Object resulting into Stegno Object, (Steganography)and further converting Stegno Object into Cipher Stegno Object (audio, video, images) using Cryptography, and is finally sent to the receiver. This proposed both the technique thus achieves double layer security to data.
