Abstract:

In cloud computing, identity authentication is the foundation of its security management. In order to effectively improve the efficiency of locating the core of fingerprint image, an algorithm of the location of the fingerprint core based on the regional division and adaptive path selection is proposed. Firstly, the fingerprint image is pre-processed through the regional division, and the adaptation path scheme is introduced based on statistical analysis, and the search region moving path of the location of the core is determined. Then, it uses the complex filter algorithm to detect the core of the fingerprint information which in the current region, and it achieves effective the location of the fingerprint core. The experimental results show that, under the premise of ensuring the accuracy of positioning, this algorithm can effectively reduce the time of the core detection and it has better detection efficiency.
