Abstract
The invention relates to a verification method and a verification system based on a biometric feature ID chain. The method includes: acquiring a biometric feature to be verified; comparing the biometric feature to be verified with a biometric feature template in an old biometric feature template region, and comparing the biometric feature to be verified with a biometric feature template in a current biometric feature template region, to respectively match at least two biometric feature IDs; generating a biometric feature ID chain on the basis of the at least two biometric feature IDs; and sending a user ID, a device ID and the biometric feature ID chain to a backend for identity verification. In the invention, a biometric feature ID chain containing the biometric feature history of a unified user terminal is generated when a biometric feature is re-entered at a local user terminal.
