Authentication system and method

摘要

An authentication server and user device are provided. The authentication server includes: a memory for storing a user identification code associated with a user; a function generator for generating a plurality of functions, the functions adapted to produce a pass code based on the user identification code; a memory for storing a function associated with the user; an application generator for generating an application adapted to implement the function on a user device; an application distributor for distributing the application to the user device; a transaction code generator for generating a transaction code for a transaction; a transaction code distributor for supplying the transaction code to the application; and a controller for receiving a pass code for the transaction from the user device and for authenticating the transaction based on the received pass code, the function, the user identification code and the transaction code.

1. An authentication server comprising:
a memory configured to store a user identification code associated with a user; function generator software configured to generate a plurality of functions that each produce a pass code based on at least one input by the user, said at least one input comprising said user identification code; a memory configured to store at least one function of said plurality of functions and associate the function with the user; application generator software configured to generate an application for execution on a user device, wherein the application implements said at least one function on the user device; an application distributor configured to distribute the application to the user device; a transaction code generator configured to generate a transaction code associated with a transaction; a transaction code distributor configured to distribute the transaction code to the application; and a controller configured to receive the pass code for said transaction from the user device and configured to authenticate the transaction on the basis of the received pass code, the function associated with said user, the user identification code and the transaction code associated with said transaction.
