Rapid authentication method based on handshape and palmprint recognition

Abstract

The invention discloses a rapid authentication method based on handshape and palmprint recognition. The method comprises: collecting a hand image and separating handshape and palmprint features from the hand image, using the extracted handshape and palmprint features of a registered user as templates and storing into registration template libraries together with personal identifications of the user; setting a threshold value, and comparing the handshape feature extracted from the shot hand image with the handshape feature in the handshape feature template library; then determining whether identification names are the same, if yes, determining that the user is legal, otherwise, determining by recognizing the palmprint; setting a threshold value, and comparing the palmprint feature extracted from the shot hand image with the palmprint feature in the palmprint feature template library, if comparison of the palmprint features is successful, determining that whether the identification names are the same, if yes, determining that the user is legal, otherwise, determining that the user is counterfeit, and refusing the user. The rapid authentication method based on handshape and palmprint recognition solves the problems that the existing hand multi-feature fusion recognition technology is slow in recognition speed and low in recognition rate, and is rapid in recognition speed, accurate in authentication effect and good in practicability.

Description

technical field [0001] The invention belongs to the technical field of biological feature identification, and in particular relates to a rapid identification verification method based on hand shape and palmprint identification. Background technique [0002] Safe, stable, convenient and efficient identity verification is an important link to avoid and suppress public security incidents. Identity verification is widely used in banking, public security, customs, e-commerce, network security, attendance, access control systems and other occasions that require personal identity verification. [0003] Traditional identification technologies often use physical objects related to people or rely on memory-related instructions for confirmation, but these identification methods often have disadvantages such as loss, damage, forgery, forgetting, theft, and inconvenient portability. Biometric identification is to verify or identify a person's identity based on a person's physiological c...
