Kind Code:
A3
Abstract:
A user identity verification method and apparatus having improved security characteristics are provided. The method and apparatus are suitable for use in a system comprising a client terminal (10) coupled to a server (20) by a first communication medium (50). A user (1) supplies a token (30) comprising first identification information to the client terminal (10), and also supplies identification information such as a memorised username. The supplied first identification information is transmitted over the first communication medium (50) from the client terminal (10) to the server (20). The server verifies that the first identification information corresponds to a stored user profile and then sends a second identification information to the user over a second communication medium (60, 40) such as a GSM network (60) to the user's mobile telephone (40). The user supplies the second identification information to the server (20) via the client terminal (10) and the user's identity is verified at the server according to presentation of the second identification information.
