Biometric identification method, portable electronic device and electronic device acquiring biometric data therefor
First Claim
Patent Images
1. A biometric identification method that is performed with a portable electronic object, comprising the following steps:
- acquiring biometric data;
generating identification information within said portable electronic object and adding said identification information to said biometric data in said portable electronic object;
storing said identification information in the portable electronic object;
providing said biometric data with the added identification information to a device other than said portable electronic object to generate a signature from said biometric data;
receiving said signature in the portable electronic object;
verifying within said portable electronic object that the received signature corresponds to the acquired biometric data by determining whether said identification information accompanies the received signature; and
comparing the received signature to a reference signature stored in the portable electronic object to authenticate an identification, if said received signature is verified to correspond to the acquired biometric data.

Abstract
A biometric identification method includes the steps of acquiring biometric data, analysing the data to produce a current signature, and comparing the current signature with a reference signature. To this process is added the further step of verifying the origin of the current signature, by determining whether the signature is actually the result of the analysis of the biometric data obtained during the acquisition phase. The verification and comparison steps are preformed in a portable electronic device, such as a smart card.
