【摘要】 指纹识别是现如今应用范围最广泛的身份鉴别手段之一,这种技术已经深入到我们的日常生活中。然而有研究指出指纹膜可以欺骗指纹识别系统,为了提升指纹识别的真实性和可靠度,通过光学相干层析(OCT)技术对手指的皮下指纹进行三维成像,发现皮下指纹信息与外部指纹信息一致,相比之下伪造的指纹膜成像结果仅有一层表面结构。因此我们认为相比现有传统的指纹检测, OCT作为一种指纹检测技术可以极大的增强指纹识别的安全性。更多还原

【Abstract】 Fingerprint recognition is one of the most widely method of identification, and this technology has penetrated into our daily lives. However, some studies have pointed out that fingerprint film can deceive fingerprint recognition system. In order to improve the authenticity and reliability of fingerprint identification, this paper uses optical coherence tomography(OCT) to image the subcutaneous fingerprint of the finger in 3 D, and find that the subcutaneous fingerprint is the same as the external fingerprint. In contrast, the imaging result of the fake fingerprint film below has only one surface structure. Therefore, we believe that compared with the traditional fingerprint detection, OCT as a fingerprint detection technology can greatly enhance the security of fingerprint recognition.更多还原
