Abstract
Method of identification or of authorization using a system comprising at least one sensor for acquiring biometric data and one secure module storing a set of digital data obtained starting from a set of respective biometric data by means of a digitization algorithm. According to this method, a biometric data value is obtained, acquired by the sensor; a digital value is obtained by application of the digitization algorithm to the acquired biometric data value; within the secure module, at least some of the digital data from said set of digital data are ranked according to their proximity to the digital value obtained; and a biometric data value is obtained from said set of biometric data by taking into account a position of the corresponding digital data within the ranking.
