This paper presents the integrated project TURBINE which is funded under the EU 7th research framework programme. This research is a multi-disciplinary effort on privacy enhancing technology, combining innovative developments in cryptography and fingerprint recognition. The objective of this project is to provide a breakthrough in electronic authentication for various applications in the physical world and on the Internet. On the one hand it will provide secure identity verification thanks to fingerprint recognition. On the other hand it will reliably protect the biometric data through advanced cryptography technology. In concrete terms, it will provide the assurance that i) the data used for the authentication, generated from the fingerprint, cannot be used to restore the original fingerprint sample, ii) the individual will be able to create different "pseudo-identities" for different applications with the same finger-print, whilst ensuring that these different identities (and hence the related personal data) cannot be linked to each other, and iii) the individual is enabled to revoke an biometric identifier (pseudo-identity) for a given application in case it should not be used anymore.
