| 摘要 |
The invention relates to a system including: a subsystem (100) for the biometric verification of the identity of a first person, and a portable object (300) which is carried by a second person and which can be temporarily coupled to the biometric verification subsystem. According to the invention, a success signal (202) is selectively activated when the biometric verification is successful and when the authenticity of the biometric verification subsystem has been confirmed by a cryptographic protocol implemented between the portable object and a coupler (250), a microcircuit (207) and a secret datum (206). The signal can be activated directly by the portable object and/or can comprise a feature (text, melody, etc.) such that observation of said signal by the second person is a guarantee that the secret datum (206) matches a reference datum (306) previously stored in the portable object, and therefore that the identity of the first person is validly verified. A subsequent financial transaction can be selectively authorised in the event of success. |
