Abstract:
Widespread use of biometric architectures implies the need to secure highly sensitive data to respect the privacy
rights of the users. In this paper, we discuss the following question: To what extent can biometric
designs be characterized as Privacy Enhancing Technologies? The terms of privacy and security for biometric
schemes are defined, while current regulations for the protection of biometric information are presented.
Additionally, we analyze and compare cryptographic techniques for secure biometric designs. Finally, we introduce
a privacy-preserving approach for biometric authentication in mobile electronic financial applications.
Our model utilizes the mechanism of pseudonymous biometric identities for secure user registration and authentication.
We discuss how the privacy requirements for the processing of biometric data can be met in our
scenario. This work attempts to contribute to the development of privacy-by-design biometric technologies.
