Abstract:
The present invention concerns a method of determining the living character of an element carrying a fingerprint. The method according to the invention is characterised in that it consists of making on the one hand at least one electrical measurement and on the other hand taking an image of the said fingerprint, and then validating the said or each electrical measurement by comparing it with the range of values of electrical measurements defined by a pre-established relationship linking the said range to characteristics of the said image.
