Fingerprint recognition is a vital component of biometric authentication, yet its reliability often declines with damaged or partial inputs. This study introduces a fingerprint verification framework based on Siamese Neural Networks (SNN) with transfer learning to enhance adaptability and accuracy. Using the Sokoto Coventry Fingerprint Dataset (SOCOFing), fingerprint images were preprocessed into labeled pairs of similar and dissimilar samples for model training and evaluation. A distinctive feature of the proposed system is dynamic class expansion, enabling new user integration without retraining. The framework also ensures privacy-preserving verification by securely encrypting and storing extracted feature embeddings. Experimental results across four difficulty levels—real, easy, medium, and hard—demonstrate high reliability and robustness in both intact and degraded fingerprint conditions. Overall, the proposed approach offers a scalable, secure, and efficient solution for fingerprint-based identification, addressing key challenges in real-world biometric authentication systems.
