Colour Image Security and Data Hiding Using DWT-SVD Transforms and ECC Encryption
Afshan taj, Anitadevi M.D · Journal of Emerging Technologies and Innovative Research · 2018
Two types of data hiding techniques are most popular in today's world, they are cryptography and steganography. Where cryptography is science of writing secret code and steganography is science art and of hiding the secret code. In cryptography data is converted to unreadable format, so that unauthorized users cannot access the secret data. Where in steganography the secret data is hidden into digital media like video, image and audio. The combination of steganography and cryptography techniques will provide the higher security while communicating on the open channel. In the proposed system Elliptic curve cryptography (ECC) technique is used for data encryption and steganography uses DWT-SVD method to hide the encrypted data. These two techniques will provide higher security and the system yields high quality image, less memory utilization, more complexity and higher embedded capacity.
