Research on optimal fingerprint input algorithm in mobile phone

As mobile phone brings great exchanges to our life, there are more and more information security problems. The uniqueness and security of fingerprint make it possible to be applied to identification of mobile phone. By analyzing the Atrua-Wing algorithm defects, the paper proposes optimal algorithm which adds matching limits to the input template. This optimal algorithm can ensure that the template is correct, improves the effect of the template and accelerates the speed of identification.
