Non Repudiation for Internet Access by Using Browser Based User Authentication Mechanism

Having a secured internet transaction is a real big challenge in this new era of net-based social engineering, hacking, impersonation and fraud. Hence, user authentication has become really important for all kinds of internet browsing transactions. This is especially true when we need to identify the exact users who have actually used the system, irrespective of the device address or location, from where the user committed internet access. The main aim of this paper will be to present a model for validating user-identity especially for internet browsing using browser software. This user validation will be carried over with respect to the ISPs which were used for service access. The main reason behind this spurred from the thought of different users using internet cafes, borrowed wireless modems or just temporary kiosks available in transport transit points like airports, restaurants and other public spots, anonymously and thus posing the danger of violating the security principle of non-repudiation. Another dangerous trend which is observed is the use of proxy programs, because of which any banned or blocked sites, can be accessed with ease. This all leads to the scenario where any unregistered user can visit, access and download any internet placed resources, for which de-centralized network infrastructures have no control of. In this paper, we are recommending a browser based user authentication scheme that can be combined with hashing and biometrics to properly validate a user so that he will be held liable for all actions committed by him in the cyber-world.
