Blockhain and Biometrics Challenges and Solutions

Abstract

Blockchain technology has garnered significant attention in recent years due to its ability to revolutionize conventional processes by providing faster, more secure, and cost-effective solutions. This study explores the symbiotic relationship between blockchain and biometrics, investigating how these technologies can mutually reinforce each other. The research makes a dual contribution: firstly, it comprehensively analyses blockchain and biometrics, highlighting their convergence's potential advantages and obstacles. Secondly, it delves deeper into utilising blockchain for safeguarding biometric templates. Although the potential benefits outlined earlier are promising, integrating blockchain and biometric technologies faces challenges due to constraints within current blockchain technology. These constraints include a limited transaction processing capacity, the need to store all system transactions leading to increased storage demands, and insufficiently explored resilience against diverse attacks. Historically, biometric systems have been vulnerable to both physical and software-based attacks. While techniques like presentation attack detection can somewhat mitigate physical sensor vulnerabilities, safeguarding against software attacks necessitates adopting biometric template protection measures. Despite advancements in this area, there remains scope for enhancing these methods. Integrating blockchain and biometrics promises to enhance security and efficiency across various sectors. By combining blockchain's immutability and transparency with biometric data's uniqueness and reliability, organizations can establish robust systems that protect sensitive information while streamlining processes. This research underscores the importance of understanding the intricacies of merging these technologies to leverage their full potential effectively. Overall, this study sheds light on the transformative power of integrating blockchain and biometrics, offering insights into how this synergy can drive innovation, improve security measures, and optimize operations in a rapidly evolving digital landscape.
