The aim of the study was to integrate fingerprint biometrics into Nigerian Correctional Information Management System (NCIMS). The traditional techniques of human identity verification suffer from security vulnerabilities such as identity theft and inconsistency; hence there was need to develop Human Identity Authentication System that verifies the true identity of convicts and ex-convicts. The system was implemented with MS Visual Studio 2013, C# on .Net framework 4.0. The backend database used was Microsoft SQL server. The design method used was Unified Model Language (UML)with tools such as Use case diagram and sequence diagram.For the methods, the existing system was analyzed; centralized database was introduced; authentication module was developed (enrolment). The developed application performance was evaluated with two hundred fingerprints alongside with related individual personal information. The result indicated 97.5% biometric accuracy levels attained with error allowance of 1% False Acceptance Rate (FAR) and 3% False Rejection Rate (FRR). In conclusion, the study showed that the integration of fingerprint biometric system into the Nigerian Correctional Information Management System will reduce identity theft by 98%, detect ex-convicts in case of re-offending and alleviate problem associated with traditional identity verification techniques if properly implemented.
