Abstract

The invention relates to a fingerprint feature point registration method based on security levels, an authentication method based on the security levels and terminal equipment. The fingerprint feature point registration method based on the security levels comprises the steps of forming the multiple security levels, wherein the multiple security levels comprise the basic security level and at least one higher security level, and each security level corresponds to one or more types of fingerprint feature points; acquiring fingerprints of a user and extracting multiple fingerprint feature points; selecting a preset number of feature points of corresponding types from the multiple fingerprint feature points based on the security levels, and registering the fingerprint feature points as fingerprint feature points with the corresponding security levels.

Description

technical field [0001] The present disclosure relates to fingerprint identification, in particular, to a method for registering fingerprint feature points based on a security level, an authentication method, and a terminal device. Background technique [0002] Certain biometric features of the human body (such as fingerprints / palmprints) are unique to the human body, and their complexity can provide a sufficient number of features for identification. [0003] Fingerprint / palmprint and other identification technologies are currently the most mature and cheap biometric identification technologies. Fingerprint identification technology has been widely used. Not only can we see fingerprint recognition technology in access control and attendance systems, but there are more fingerprint recognition applications in the market: such as laptops, mobile phones, cars, and bank payments can all apply fingerprint recognition technology. Especially with the continuous development of smar...
