Secure Storage on Cloud using Hybrid Cryptography with Graphical Password Authentication

Abstract

Authentication service has been advanced by implying advancement in security using cryptography to protect password against data leaking and sniffing. But there is a possibility of  shoulder surfing which can lead to data insecurity. Studies shows that graphical or image passwords is more secure because the possibility of guessing is very low. During storage of file, it is encrypted using a single algorithm and there is possibility of data leakage if the encryption algorithm is found. This paper presents a review of a system which aims  to provide login security using the graphical password technique and to provide file security using hybrid cryptography, thereby providing the  user  with  highly secured file security system.
