Abstract:
1. A method for verifying the identity of a person based on a sequence of feature components extracted from a biometric sample from the person, comprising: quantizing each feature component of said sequence of the feature components, assigning a data bit sequence to each quantized feature component in such a way that data bit sequences for adjacent quantization intervals have a Hamming distance of 1, wherein a data bit sequence for one quantization interval exhibits a Hamming distance of 1 from a data bit sequence in a next quantization interval adjacent thereto, concatenating said data bit sequence into a bit string with the data bit sequences assigned to each other quantized feature component, combining said bit string with a helper data set using an exclusive disjunction (XOR) operation into a codeword, decoding said codeword into a secret, and matching a second secret with the decoded secret.
