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

Abstract

The invention discloses an electronic lock and an unlocking method thereof. The unlocking method comprises steps as follows: S1, original image acquisition; S2, original image preprocessing; S3, fingerprint image verification; S4, vein image verification; S5, unlocking. The electronic lock is unlocked through sequential multiple verification including fingerprint image verification, vein image verification and the like, vein image verification can be performed only after a user passes fingerprint image verification, and unlocking can be realized through three-dimensional characteristic data-based living fingerprint verification conducted after the user passes vein image verification, so that the safety performance of the electronic lock is improved; vein image verification overcomes the defect that fingerprint verification is easy to copy, and the safety performance of the electronic lock is further improved.

Description

technical field [0001] The invention relates to the technical field of biometric identification, in particular to an electronic lock and an unlocking method thereof. 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...
