Abstract

The invention discloses a fingerprint identification unlocking system which comprises a lock body, a lock box and an alarm, the lock box and the alarm are mounted on the lock body, and a feature vector processor, a first memory, a registered fingerprint processor, a second memory, an identification fingerprint processor, a fingerprint matcher, a controller and a wireless communication module are mounted in the lock box.The first hash template and the second hash template obtained by the invention have better removability and non-relevance, so that the safety is better, the matching operation is carried out under the condition of an encryption domain, the original template information cannot be leaked even if the templates are lost, and the safety of unlocking by utilizing the fingerprint is improved.

Description

technical field [0001] The invention belongs to the technical field of fingerprint identification, and in particular relates to a fingerprint identification unlocking system. Background technique [0002] With the rapid development of social urbanization, there are more and more large and medium-sized cities in our country. Therefore, the safety management system of buildings is becoming more and more important. One of the most important pieces of equipment today for building security is the lock. Due to the simple structure and low security performance of traditional mechanical locks, and the keys are easy to be copied, thefts are common, and it is difficult to effectively protect people's daily life. On the other hand, along with the continuous development of science and technology, electronic combination locks with anti-theft alarm function gradually replace traditional mechanical locks and enter people's lives, which can overcome the shortcomings of mechanical locks wit...
