abstract = {multi-algorithm biometric systems consolidate information from multiple feature extraction algorithms applied to single biometric traits, providing robust authentication without additional sensor overhead. This paper presents a comprehensive framework for multi-algorithm biometric person authentication using basic Particle Swarm Optimization (PSO) for optimal feature selection at the feature-level fusion stage. The study systematically applies PSO to fingerprint, iris, and palmprint multi-algorithm systems using standard PSO formulation with velocity-based position updates and binary discretization. Experimental validation on benchmark databases (CASIA, IITD, FVC) demonstrates that basic PSO achieves 94-97% recognition accuracy with 80-88% feature space reduction using Euclidean distance matching and up to 96-97% accuracy with supervised classifiers (C4.5, SMO). The approach outperforms traditional dimensionality reduction methods (PCA) with 10-15% accuracy improvements while maintaining comparable feature reduction ratios. Computational analysis shows PSO requires 50-60 seconds for feature selection (one-time offline cost) with acceptable testing time (0.08 seconds), enabling practical deployment in real-time biometric authentication systems. The paper provides detailed implementation specifications, extensive experimental validation across multiple classifiers, and practical insights for PSO-based feature selection in biometric systems.},
