Abstract:
1. A biometric method adapted for a biometric apparatus, comprising: the biometric apparatus providing an hashed registered data and an adjustment value, wherein the step of providing the hashed registered data and the adjustment value comprises: the biometric apparatus extracting a biometric data; the biometric apparatus adjusting the biometric data to a adjusted biometric data according to the adjustment value; the biometric apparatus defining the value ranges according to the threshold, wherein each of the value ranges has a quantization value; the biometric apparatus using the quantization value of one of the value ranges as a quantified data for replacing the adjusted biometric data if the adjusted biometric data falls within the value range; the biometric apparatus performing the one-way hash function to convert the quantified data into an hashed data; and the biometric apparatus comparing the hashed registered data and the hashed data.
