Authentication systems used today are quite insecure. Generally every person has it’s own User_ID and Password for secure login. For authentication password must be known only to the particular person. But it’s of no use when same one else hacks ID and Password. Search reranking is one of the effective approaches to refine the text-based image search result. The strategy used in our project is the solution to overcome the above problem. The strategy is to use face recognition system with GSM Tech. Whenever one wants to login. After entering ID and Password & clicking submit button, system will take snap of the user. It try to match the image with the image of the user in database. If it matches with the database image system will complete the authentication and if it doesn’t match, system will send E-mail containing the image of invalid user as well as send message to the registered user’s mobile number using GSM Tech. The registered user will have privilege to shut down the machine if any such kind of suspect occurs by sending the shutdown’ message to the machine.
