Abstract
A method for generating a code 3 based on first biometric characteristics 2′, to a method for verifying a code 3, to a document 4 comprising the code 3, and to the use of the code 3.
Claims40
A method for generating a code based on biometric characteristics,
- wherein the method comprises at least the following steps:
- a) capturing at least one biometric information item from a real person, a photograph and/or a video,
- b) extracting first biometric characteristics from the at least one biometric information item in the form of a first data set,
- c) compressing the first data set to obtain a compressed first data set,
- d) adding a second data set comprising useful data to the compressed first data set,
- e) generating a first hash value of the compressed first data set or of the compressed first data set and the second data set,
- f) generating a signature for the first hash value,
- g) generating the code in the form of a geometrical pattern comprising the first compressed data set, which is based on the first biometric characteristics, and comprising the first hash value and the signature.

A method for verifying a code wherein the method comprises at least the following steps A) or B):
- A) creating a compressed third data set, wherein the compressed third data set is based on second biometric characteristics, wherein step A) comprises at least the following sub-steps:
- capturing at least one biometric information item of a real person, a photograph or a video,
- extracting second biometric characteristics from the at least one biometric information item in the form of a third data set,
- compressing the third data set to obtain a compressed third data set, or
- B) opening a database which comprises at least one compressed third data set, wherein the compressed third data set is based on second biometric characteristics,
- wherein the method also comprises at least the following steps:
- h) reading out a compressed first data set from the code, wherein the compressed first data set is based on first biometric characteristics, and comparing the compressed first data set with the compressed third data set,
- i) generating an evaluation parameter that allows the evaluation of a correspondence of the compressed first data set with the compressed third data set,
- j) outputting an evaluation on the basis of the generated evaluation parameter.
