Bakare K.A., Junaidu S.B., Ahmed M.Y. . Improved Secure Biometric Authentication Protocol. International Journal of Applied Information Systems. 12, 31 ( July 2020), 49-56. DOI=10.5120/ijais2020451866
This paper presents an improvement to algorithm used in remote biometric authentication protocol [1]. A good remote biometric authentication protocol is expected to ensure secrecy of biometric data against all kinds of threats. This paper improves the security protocol algorithm by ensuring that secrecy of data is maintained when threat model in [1] is tested on the protocol. Security protocols should be flexible enough to guarantee Secrecy of data regardless of the intruder model. Network threat model in [6] is considered the foundation when analyzing security protocols and the remote biometric authentication protocol [1] was implemented on this threat model. The work of [6] assumes that the adversary has taken over the communication channel which allows the adversary to intercept and modify messages in transit. Scyther tool for protocol analysis implements threat model of [2] and was used in verifying and validating the property of Secrecy-of-Data for remote biometric authentication protocol. Therefore, the scope of this paper entails improving only the property of Secrecy-of-Data for remote biometric authentication protocol when faced with a threat model.
