Enhancing Security of Multibiometric Cryptosystem Using RSA
Single biometric cryptosystems were developed to obtain security and privacy. They are seriously affected by various attacks. Binding of multiple biometric cryptosystems (e.g., Fingerprint, Iris and face) together is termed as multi-biometric cryptosystem. Now-a-days Multi-biometric systems are mostly used in many large-scale biometric applications (e.g., FBI-IAFIS) multi-biometrics have several advantages over single biometric cryptosystem, it has low error rate. Multi-biometric template may be modified by the attacker. To deal with this issue in this paper, the authors propose a multi-biometric cryptosystem which use RSA cryptography to secure multi-biometric Template.
