A description is given of a method and a device allowing the generation of a feature vector of a human fingerprint by means of a series of processes performed on the basis of the image of said fingerprint. These vectors are used to produce a classification, indexing or determination of fingerprint identity and also to protect secrets or to generate cryptographic keys based on fingerprints. The majority of identification methods use feature vectors and techniques for extraction and comparison purposes, which are unsuitable for electronic devices with reduced computing and storage resources. The method proposed in this invention is indeed appropriate, offering good levels of performance in terms of vector extraction times, pairing and ordering times, and memory requirements. The main uses of the invention arise in small automatic fingerprint identification systems that are portable, inexpensive and/or secure, where the user is present and wishes to be identified. |
