Safe electronic lock and unlocking method

Abstract

The invention discloses a safe electronic lock and an unlocking method. The unlocking method comprises the following steps: S1, an original image capture step; S2, an original image preprocessing step; S3, an original image verification step; S4, a finger living body verification step; S5, an unlocking step. According to the unlocking method, in order to realize unlocking of the electronic lock, multiple verifications such as original image verification, finger living body verification and password verification need to be performed successively, and unlocking can only be realized when all the verifications are passed, so the safety performance of the electronic lock is greatly improved; during finger living body verification, pieces of feature data obtained by collection are coupled into three-dimensional data, a fingerprint center point is obtained in the three-dimensional data according to a fingerprint center point location algorithm, and whether a finger is a living body or not is judged by the relative position of the fingerprint center point and a finger vein, thus preventing another person from fabricating a finger and passing verification, and improving the safety performance of the electronic lock.

Description

technical field [0001] The invention relates to the technical field of biometric identification, in particular to a safe electronic lock and an unlocking method. Background technique [0002] Biometric authentication technology is now widely recognized and has been certified by national certification bodies and is widely used in various industries. Due to its lifelong invariance, uniqueness and convenience, fingerprint has almost become synonymous with biometric identification. Fingerprints are the uneven lines on the skin on the front of the end of a person's fingers. The lines are arranged regularly to form different grain patterns. The starting point, ending point, joint point and bifurcation point of the ridge line are called the minutiae feature points of the fingerprint. However, the existing fingerprint recognition has the following defects: (1) Some people or certain groups have few fingerprint features, which makes it difficult to image; Fingerprint imprints may...

Problems solved by technology

However, the existing fingerprint recognition has the following defects: (1) Some people or certain groups have few fingerprint features, which makes it difficult to image; Fingerprint imprints may be used to copy fingerprints, such as fingerprint sleeves and fingerprint films in an electrical appliance store; (3) Fingerprints are important personal information of users. In some applications, users are worried about information leakage, burying major security risks
