The Research of Double-Biometric Identification Technology Based on Handprints

Single biometric identification becomes the bottleneck problem of biometric identification technology inevitably because of its limitation and objectivity. In order to solve the problem, double biometric identification technology will become the main direction of future development. This article is based on this idea and adopts handprints recognition which combines fingerprints recognition with palmprints recognition. It aimed at the complexity and diversity of handprints image and brought forward double biometric identification technology which is based on the handprints. The shortage of fingerprints recognition or palmprints recognition has been overcomed greatly by the methods of Gabor and Wave-let Zero-crossing. Multi-biometric Identification not only improves the efficiency of identification, but also guarantees the accuracy and security of the identification´s outcome.
