Abstract Cancelable biometrics is an important biometric template protection technique. However, many existing cancelable fingerprint templates suffer post-transformation performance deterioration and the attacks via record multiplicity (ARM). In this paper, we design alignment-free cancelable fingerprint templates with dual protection, which is composed of the window-shift-XOR model and the partial discrete wavelet transform. The former defuses the ARM threat and is combined with the latter to provide dual protection and enhance matching performance. The designed cancelable templates meet the requirements of non-invertibility, diversity and revocability and demonstrate superior recognition accuracy, when evaluated over public databases; for example, the Equal Error Rate of the proposed method in the lost-key scenario under the 1vs1 protocol is 0% for both FVC2002 DB1 and DB2, 1.63% for FVC2002 DB3, 7.35% for FVC2004 DB1 and 4.69% for FVC2004DB2.

具有双重保护的免对齐可取消指纹模板

摘要 可撤销生物识别技术是一种重要的生物识别模板保护技术。然而，许多现有的可取消指纹模板遭受转换后性能恶化和通过记录多重性（ARM）的攻击。在本文中，我们设计了具有双重保护的免对齐可取消指纹模板，该模板由窗口移位异或模型和部分离散小波变换组成。前者化解ARM威胁，与后者结合，提供双重保护，增强匹配性能。设计的可取消模板满足不可逆性、多样性和可撤销性的要求，在公共数据库评估时表现出优越的识别准确性；例如，
