Accidental vocal print password validation system, accidental vocal print cipher lock and its generation method

Abstract

The invention provides a random sound trace verifying system, which comprises a training system, a random password generator and a testing system, so that the original input voice data is performed training and testing operation. In the voice training, the training system acquires a designated sound trace feature model parameter set from the original input voice data and a plurality of sound trace feature units from the designated sound trace feature model parameter set and incorporates into at least one reference sound trace password set to provide voice testing operation for the testing system. In executing the voice testing, the random password generator generates randomly at least one reference sound trace password set from the sound trace feature unit of the designated sound trace feature model parameter set to form a random sound trace password lock. The invention achieves the effect of avoiding illegal repack by randomly generating one or more reference sound trace password set, that is, the random sound trace verifying system completes setting to form the random sound trace password lock.

Description

technical field [0001] The present invention relates to a random voiceprint verification system, a random voiceprint cipher lock and a method for generating the same, in particular to using several voiceprint feature units to randomly combine to form one or more reference voiceprint cipher groups. One or more reference voiceprint cipher groups constitute a random voiceprint cipher lock for a random voiceprint verification system that performs voiceprint verification operations, and the random voiceprint verification system provides a voiceprint cipher lock and a method for generating the same. Background technique [0002] At present, the use of personal biometrics for identity recognition has gradually become the main technology for personal identity recognition. In terms of recognition technology, currently available biometric features include face recognition, fingerprint recognition, palmprint recognition, voiceprint recognition, eye iris recognition, and deoxyribonuclei...

Problems solved by technology

However, the No. 490655 patent must calculate the distance between the reference sample and the test sample when performing pattern matching and distance calculations

In fact, Patent No. 490655 only sets a single reference sample, so it may be subject to illegal cracking, such as playing illegal pre-recorded voiceprint data
