Télécom SudParis and IDEMIA present BioDigital, a new biometric technology to combat identity spoofing

Following an 18-month collaboration agreement, Télécom SudParis and IDEMIA, the global leader in Augmented Identity, have finalised the design of a contactless biometric reader, based on a patent filed by two Télécom SudParis researchers. The transfer of technology to IDEMIA is now completed.

Fingerprint spoof detection

Fingerprint recognition

The technology involves a new generation digital fingerprint reader known as BioDigital. It provides an effective defence against identity spoofing, but also offers a solution to the difficulties inherent in the very nature of biometric data, achieving improved recognition of damaged fingerprint surfaces.

The close cooperation between Télécom SudParis and IDEMIA, as part of which the Group provided an assessment algorithm and created a database for its evaluation, was able to demonstrate that BioDigital is capable of providing safer and more effective fingerprint matching, with a success rate bordering on 100%.

Subcutaneous fingerprint and pore network recognition

This contactless technology recognises not only the fingerprint itself, but also the subcutaneous print and the network of sweat pores. It relies on optical coherence tomography (OCT), a technique that produces 3D images from “echoes” of backscattered light. BioDigital thus offers access to fingerprints without direct contact with the reader. This innovative new feature is also accompanied by outstanding image reconstruction quality.

Thanks to the merging of phase and intensity images, we have succeeded in obtaining the most natural image possible.
Yaneck Gottesman, a research fellow at Télécom SudParis

The real originality of our technology lies in the quality of the reconstructed image of the internal fingerprint.
Bernadette Dorizzi, Dean of Research at Télécom SudParis

On a certain number of critical applications such as the protection of sensitive infrastructure, the issue of such spoofing attacks is very real, and it is a race between hackers and tech developers like IDEMIA. This technology, once rolled out and integrated into our products, has the potential to put us another length ahead.
