| 摘要 |
The invention relates to an authorisation system (2), characterized by an integrated circuit card (4) which incorporates camera means (14), data processing means (12,18), and memory means (161) in which is stored at least one digital image of an authorised user of the system. The card (4) is separable from a host means (6), when not in use. Communication means (20,21) are arranged to ensure encrypted communications between the card (4) and the host means (6). The camera means (14) is arranged to produce an image of a user and to forward this image to the processing means (18) for comparison with the or each image of an authorised user stored in the memory means (161). The processing means (18) produces a signal indicative of the result of the comparison, which is communicated in an encrypted form to the host means (6). <IMAGE> |
