改进的可撤销指纹Fuzzy Vault方案
Improved cancelable fingerprint fuzzy vault system
摘要
Abstract
Fuzzy vault has been widely applied in biometric encryption domain for key binding, suitable for set feature representation, such as minutiae set of fingerprint image. However, with the real minutia points contained in vault, fuzzy vault is suffered from cross matching problem, which makes attackers easily obtain real minutia information from multiple vault templates and threatens user privacy and secret key security. In this paper, an improved cancelable fuzzy vault scheme is proposed, in which an one-way function based on password is constructed to transform original minutia information and then the transformed minutiae are fed to fuzzy vault system. The attackers can not obtain the original minutia features even though multiple vaults are at hand, and the users can reissue a new vault template by changing password. Experimental results on FVC2002 DB2 show that the proposed method can effectively reduce the hidden troubles and increase security of system.关键词
