Visual Cryptography is an encryption technique that hides information in the images such that it can be decrypted by the human vision if the correct key image is used. This technique divides a secret image into various parts called shares depending on the variation of pixels. Biometrics deals with the automated methods of verifying the identity of a person based on physiological or behavioral characteristics. This project aims to implement visual cryptography and biometric authentication to build a secure locker system. The fingerprint image of a user is considered as a secret image to generate shares that will be distributed among admin database and user. Authentication will take place by comparing the real time fingerprint image of the user and the image generated from the combination of the shares.
Virtual Environment Forensics is the process of performing the digital forensics in virtual environment. In recent time, virtualization technology has become one of the most important and popular technologies for individuals and companies due to its many advantages like cost benefits for storage, processing and computing resources. New techniques and methods of cybercrimes against virtual environments are used by attackers. Thus there is a need for designing and developing new techniques and tools to investigate new type of cybercrimes. [1] In this paper, the computer forensic investigations with respect to the vital role of virtual environments have been analysed. Vulnerabilities in a virtual environment and some existing forensic tools are studied. We propose design of a forensic tool to analyse the evidences left by an attacker. Further this tool will try to relate the evidences in a presentable form which can be readily used by law enforcement to lead to the final suspect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
