Abstract

The present invention relates to a method for authenticating a transaction using a biometric identifier and a portable data store. The method comprises: generating a first bit pattern of a user'"'"'s iris from a captured image of the user'"'"'s iris; accessing a user profile stored on the portable data store, the user profile comprising a pre-stored second bit pattern of an authentic user'"'"'s iris; comparing the first and second bit patterns; and generating an authentication signal to authenticate the transaction, when the first and second bit patterns are equivalent. In addition, the present invention relates to apparatus for carrying out the present method.

10. The method of claim 7, wherein the comparing step and the authentication signal generating step are carried out on a remotely located server in operative communication with the portable data store terminal.

11. The method of claim 7, further comprising:

receiving the authentication signal at the portable data store terminal and proceeding with the transaction.

12. The method of claim 5, wherein the generating step comprises capturing an image of a user'"'"'s iris and generating the first bit pattern from the captured image, and the portable data store terminal comprises a camera arranged to capture an image of a user'"'"'s iris.

13. The method of claim 1, further comprising:

generating a one-time password (OTP) in response to the generation of the authentication signal.

14. The method of claim 13, wherein the accessing step is carried out on a portable data store terminal, and the OTP is generated at the portable data store terminal.

15. A data store authentication terminal, for authenticating a transaction using a biometric identifier and a portable data store, the terminal comprising:
