A review of optical image encryption techniques based on Cloud computing biometric and multiple image processing

Abstract

Cloud Computing technology has become one of the most powerful technologies in terms of high availability, flexibility, and scalability. Besides all the widely perceived benefits of cloud computing, there is a concern that makes the use of the cloud leads to a potential risk that is security. To overcome security issues, a strong authentication mechanism is required. Biometric authentication is one of the very popular methods used for identity detection so that only an authorized person can access the system, one method to achieve this is image processing. In this paper, we review various optical image encryption techniques based on the optical Double Random Phase Encoding (DRPE) system, the oldest and most extensively investigated optical scheme. In the literature, we get an overview of digital image processing applications and data encryption schemes. The various parameter used to measure the image encryption level is discussed. The optical Double Random Phase Encoding method and its numerical simulation are then investigated. In addition to it, other optical encryptions techniques such as multiple image cryptosystem extension and different techniques are discussed that enhance the optical encryption security, which is used widely and generally appreciated. We explored the cloud framework via the biometric authentication process to authorize the legitimate user and permission checks is done by the biometric system. The level of security of the overall system increases when the authorization process is strong and faultless. The challenges faced in this area and the objectives of the research have been discussed.
