Biometrics group counters privacy fears

1 Privacy in Biometrics

Biometric features are increasingly used for authentication and identification purposes in a broad variety of institutional and commercial systems, such as e-government, e-banking and e-commerce applications. On the other side, the adoption of biometric techniques is restrained by a rising concern regarding the protection of the biometrics templates. In fact, people are not generally keen to gi...

Privacy Enhancing Technologies in Biometrics

In the recent past we have witnessed the rapid spreading of biometric technologies for automatic people authentication, due to the several inherent advantages they offer over classic methods. Biometrics can be defined as the analysis of physiological or behavioral people characteristics for automatic recognition purposes. Biometric authentication relies on who a person is or what a person does,...

Privacy preserving biometrics using partially homomorphic encryption

We will look into privacy preserving biometrics using the example of a fingerprint reader and partially homomorphic encryption. Therefore we will cover the basics necessary to understand the discussed subject, partially homomorphic encryption and fingerprint based authentication, as well as showing a concrete protocol and its implications on performance and security of the system. While securit...

Privacy Preserving Key Generation for Iris Biometrics

In this work we present a new technique for generating cryptographic keys out of iris textures implementing a key-generation scheme. In contrast to existing approaches to iris-biometric cryptosystems the proposed scheme does not store any biometric data, neither in raw nor in encrypted form, providing high secrecy in terms of template protection. The proposed approach is tested on a widely used...
