SYSTEM AND METHOD FOR SECURITY ENHANCEMENT

摘要

A system and method thereof for secure authentication using multimedia contents set particular to user (MCSPU) and user specified parameters is disclosed. A host system for performing an authentication with a user system is disclosed. The host system comprises of a processor; and a memory coupled to said processor for executing a plurality of modules present in said memory. For the authentication (while logging in or performing a transaction), the host system would provide to the user one or more elements belonging to MCSPU, after embedding, within the elements the authentication related critical information using the user specific parameters. The proposed method ensures the user that the response is coming from authentic system. In case of suspicious user behavior, the parameters or multimedia contents not specific to the user could be used.

1. A method for authentication, between a user system and a host system, the method comprising:
receiving from a user, a set of at least one user specified multimedia content and a set of user specified parameters; storing said set of at least one user specified multimedia content and said set consisting of user specified parameters, using said host system; receiving from said user system, information associated with said authentication from said user; embedding using said host system, a critical information based on said information received, using said set of user specified parameters and random parameters, in said one or more user specified multimedia content stored, thereby modifying one or more user specified multimedia content stored into modified multimedia content; transforming said modified multimedia content into an authenticating multimedia content; sending from said host system to said user system, said authenticating multimedia content and related information; presenting to said user, said authenticating multimedia content and related information, wherein said authenticating multimedia content is perceivable by said user; receiving an input from said user, the input indicating verification of said authenticating multimedia content and for proceeding said authentication; and performing said authentication, using said host system, based on said input received from said user.
