摘要：The proposed system implements a prevention technique to protect trespassers, the trespassers is someone who intrudes on the privacy or property of another without permission. This also helps to avoid brute force and dictionary attacks. Text password is the most popular form of user authentication on websites due to its convenience and simplicity. Firstly, users often select weak passwords and reuse the same passwords across different websites. Routinely reusing or using passwords on different unknown machine causes a domino effect; when an adversary compromises one password, she will exploit it to gain access to more websites. Second, typing passwords into un trusted computers suffers password thief threat. An adversary can launch several password stealing attacks to snatch passwords, such as phishing, key loggers and malware .In this paper, we design a user authentication protocol that only requires each participating website possesses a unique phone Number, and involves a telecommunication service provider in registration and recovery phases. Through SMS the encrypted password will be send to the user. The user should forward the same message with their security answer to the server. The server will verify the details and allow them to access their personal page. Here also problem occurs if the user have joint account, here the SMS send to both the person, if one is using net banking then the message is send to both the user from the server side, and then ask for permission whether the other one can use net banking, if the other one says yes to this queries, the other one can start his/her transactions in a secure manner.
