Abstract
A method carried out by a smart card including a fingerprint sensor, the method including an authentication phase including: acquiring a sequence of object prints from objects detected over time by the fingerprint sensor; comparing the sequence of object prints with reference data defining a reference sequence of object prints according to at least two different print types; and determining that the authentication phase is successful if the sequence of object prints coincides with the reference data. During a digital enrollment phase, the smart card generates, from at least one fingerprint, called enrollment fingerprint, digital enrollment data; and records these digital enrollment data so as to allow subsequent digital authentication from said digital enrollment data.
