Protection of Biometric Data: New Technologies and Ethical Issues

Abstract

Biometric data (fingerprints, facial recognition, iris scanners, etc.) are widely used in modern business processes for authentication and security. This article analyzes the role of new technologies (homomorphic encryption, blockchain, zero-trust systems) in protecting biometric data and the ethical issues that arise in this field. The study aims to evaluate innovative solutions for enhancing the security of biometric systems and to examine their ethical implications. The findings indicate that advanced encryption and decentralized systems improve data security, yet ethical challenges such as privacy, consent, and discrimination remain unresolved. Recommended measures include increasing transparency, implementing ethical guidelines, and harmonizing international standards. This research provides businesses and policymakers with a practical guide for the secure and responsible use of biometric data.
