In this paper, orthogonal transforms with their wavelet transforms and Hybrid wavelet transforms are proposed to be used for image steganography using Kekre, Walsh and Sine transforms. Transform domain techniques performs better in case of attacks on stego image. A set of 10 Cover images for hiding 10 multifarious message images has been used for(More)
Homomorphic Encryption enables us to perform operations on encrypted data without decrypting it. This method is well suited for enhancing the performance and security where the cloud service providers wouldn’t have access to the user’s data. A Fully homomorphic encryption is still challenged and is proposed with improved methods for its improved efficiency(More)
