Visual Cryptography Based Authentication Technique for Cloud Environment using SVD Factorization

Abstract

World is going toward digitalization and cloud computing plays an important role to connect digital devices for communication with each other. Communication with authentic device and secure its illegal access is the main feature of cloud providers. With the growth of cloud technologies attackers are also finding different attack vectors to break down the cloud authentication system. Previous research illustrates that there is need to develop strong authentication technique to strengthen the trust on cloud systems. This paper demonstrated a visual cryptographic authentication technique for cloud environment. The technique is based on the SVD factorization method. SVD works effectively to create multiple shares of an image and make strong authentication algorithm on the basis of random image feature selection. Result analysis shows that SVD factorization works effectively rather than LU factorization in cloud environment.
