摘　　要：为解决脱皮、有伤痕等低质量指纹识别困难、识别率低及稳定性差问题。提出将数据融合技术应用于指纹识别中。采用验证性的识别方法及离散性的特征提取手段,运用D-S证据理论,给出一个多指纹图像融合的辨识框架,计算益集元素的逻辑,得到多指纹融合的可信度,由此来辨别身份的真伪。通过仿真实验,表明此方法实用、有效,能提高系统的识别率及稳定性。可广泛应用于刑侦、金融等对安全有严格要求的领域。In order to solve the problems of difficulty,low efficiency and instability of identification the finger- prints with inferior quality because of desquamating or scar,we set forth the method of utilizing the technology of data synthesis in identification of fingerprints. By utilizing identification with verifiability and discrete extraction, using D-S evidence theory,we present an identification frame with the synthesis of multi-fingerprints images. With the calculation of the logic of power set elements,the reliability of the synthesis of multi-fingerprints is ob- tained,with which we can identify the truth from falsity. The simulation shows that this method is practical,ef- fective,and also it contributes to enhance the efficiency and stability of identification. This technology can be widely used in police and banking industries which have high demand for safety.
