The invention discloses a two-dimensional bar code type identity authentication method based on fingerprints and a human face, belongs to the technical field of image processing, and relates to fingerprint recognition processing technology, human face recognition technology and two-dimensional bar code technology. The method mainly comprises the following four parts: 1, extraction of fingerprint characteristics; 2, extraction of human face characteristics; 3, generation of two-dimensional bar codes based on the fingerprints and the human face; and 4, recognition and identity authentication based on the two-dimensional bar codes of the fingerprints and the human face. The method combines the fingerprint characteristics and the human face characteristics of an individual to code, to add error correcting codes and to encrypt, and then expresses the characteristics by adopting a two-dimensional bar code mode, so the method has the advantages of large information capacity, low cost, high reliability, strong confidentiality and anti-falsification, and the like. The method can be applied to the fields of industry and commerce, national defense, transportation, finance, health and medicine, post and telecommunications, office automation, and the like.
