Fingerprint verification method and device, electronic equipment, and storage medium

Abstract

The invention discloses a fingerprint verification method and device, electronic equipment, and a storage medium. The method comprises the following steps: acquiring a target face image of a user; according to the target face image, acquiring a target fingerprint matching degree threshold of the user; acquiring fingerprint information input by the user; carrying out searching and matching on the fingerprint information based on a preset fingerprint database, so that the maximum fingerprint matching degree of the fingerprint information is acquired; judging whether the maximum fingerprint matching degree is no smaller than the target fingerprint matching degree threshold or not; and if the maximum fingerprint matching degree is no smaller than the target fingerprint matching degree threshold, generating an unlocking command, wherein the unlocking command is used to control a door lock to be unlocked. The fingerprint verification method and device, the electronic equipment and the storage medium disclosed by the invention have the advantages that the face image of the user is acquired to obtain the corresponding fingerprint matching degree threshold, and a fingerprint input by the user is verified according to the fingerprint matching degree threshold, so that different users can carry out fingerprint verification based on the corresponding fingerprint matching degree thresholds;and therefore, high safety of the door lock fingerprint verification is ensured, and the fingerprint verification efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of smart home, and more specifically, to a fingerprint verification method, device, electronic equipment and storage medium. Background technique [0002] At present, smart door locks with fingerprint unlocking function often directly compare and match the collected fingerprints with the fingerprints that have been entered and saved when performing fingerprint verification and unlocking. If the fixed fingerprint matching threshold is set, the identification fingerprint verification is passed, and then the unlock operation is performed, otherwise the fingerprint verification is unsuccessful and the lock cannot be unlocked. However, due to the difference in gender and age of users, the quality of the collected fingerprints usually varies greatly. If the preset fixed fingerprint matching threshold is high, the elderly, children and other groups will have a high rejection rate, resulting in the failure...

Problems solved by technology

However, due to the difference in gender and age of users, the quality of the collected fingerprints usually varies greatly. If the preset fixed fingerprint matching threshold is high, the elderly, children and other groups will have a high rejection rate, resulting in the failure of fingerprint verification. The probability is high, but if the preset fixed fingerprint matching threshold is low, the security and reliability of fingerprint verification cannot be guaranteed
