Periodic Report Summary 2 - INGRESS (Innovative Technology for Fingerprint Live Scanners)

Project Context and Objectives:
The objective of INGRESS is to research, develop and validate innovative technology to take fingerprint images by looking at additional biometrics associated with the finger. The project will pave the way to the manufacturing of innovative fingerprint scanners capable of properly sensing fingerprints of intrinsic very-low quality and/or characterized by superficial skin disorders.
The project focuses on capturing sub-surface fingerprint and delivering a high-quality image. The technology stream of the project focuses on medical imaging technique, such as ultrasound and Full Field Optical Coherence Tomography (FFOCT), to acquire the fingerprint matrix in the dermis. Furthermore, INGRESS studies the use of Printed Organic Electronics (POE) technologies and components, such as the passive matrix of Organic Light Emitting Diodes (OLED) and Organic Photo Diodes (OPDs) to create a new generation of high-resolution fingerprint sensors.
We propose to evaluate the INGRESS’ mock-ups in laboratory to compare them with legacy sensors. Tests in the field will evaluate the technology performance, the usability and user acceptance of the solution. INGRESS exploits both standard approaches and novel metrics to evaluate the operational quality of fingerprint scanners.
In parallel of the technology stream, the project will investigate the potential ethical, legal and societal issues for these novel technologies. The R&D process will integrate, all along the project, the results from this investigation, to guarantee that all end-products will be fully compatible/compliant with current trends in European and international privacy and data protection standards, following the internationally-endorsed foundational principles of Privacy by Design.
INGRESS will both validate the developed technologies and propose a technology development roadmap for the purpose of using fingerprints from the identity document in border control and law enforcement applications.

Project Results:
At the end of reporting period 2, the main achievements are described below.

The project performed the requirements and stakeholder analysis with an updated version of the corresponding deliverable following feedback of PO during annual review (WP1).

The technical work on the chosen fingerprint capture technologies has started and is still in progress.
New sensors development includes ultrasound, OCT and POE technologies (WP2, WP3, WP4).
Regarding ultrasound, two mocks-up have been developed by CNRS. The second and last one did not allow the visualization of internal fingerprint as expected. CNRS concluded that for their technology there is a major gap to fill that is not reachable within the project’s budget. OPTEL developed several version of their ultrasound mock-up that allows to see external fingerprint, with quite good quality. Internal fingerprint reconstruction is still in progress.

For OCT, CNRS built a mockup (using d-FF-OCT and InGaAs camera) giving good results with clear visualization of the internal fingerprint. New OCT sensor with Silicon camera, cheaper and more compact, has been also developed and is being imporved to achieve similar image quality than the previous mock-up.

For POE technology, the mockup development is progressing. Stand-alone OPDs and the OPD arrays have been fabricated and tested. It allowed the realization of the 64dpi POE mock-up and workis in progress to reach 128dpi resolution. Next step will be 512dpi once the technology has been validated on lower resolution.

Significant work has been done on altered fingerprint (WP5): tests were performed on alteration detection algorithms and the results were discussed with involved partners (GUC, MPH, UNIL). Draft paper on the work is in progress. Tests were also performed on altered fingerprint algorithms (from UBO, MPH and UNIL) and the work on detection and matching of altered fingerprint was finalized with the delivery a report.
Additionally, the first images from new sensors, received from CNRS for the Ultrasound and OCT systems, were analysed by UBO and MPH (WP5): ultrasound images have poor quality for the moment while OCT images are promising, as external and internal images have quite good quality. A first step on image processing for OCT and OPTEL sensor has been done.

Image quality assessment (WP6) did some progress, with especially the delivery of tools for the estimation of fingerprint scanner quality characteristics and for assessment of fingerprint image quality.

Data collection (WP7) has started. It has been launched and realized in Turkey, with three sensors: OCT from Institut Langevin (CNRS), OPTEL and Morpho sensor. Test campaign with the collected data is in progress.

For ethical, legal and societal issues (WP8), the report relative to information ethics analysis was finalized. The data collection, for the report analysis of data protection laws, is in progress.

Dissemination, valorisation and standardization activites (WP9) took place with publications from diverse partners, the participation to EAB-RPC 2015 conference (September 7 and 8, 2015) and meetings on ISO/IEC SC 37 Standardization.

Potential Impact:
The major impact of INGRESS is to develop innovative technologies for looking and acquiring additional biometrics linked to the finger that will complement existing techniques. The solutions proposed in the project offer major improvement in the way of acquiring biometrics. They mainly address the issue of superficial skin disorders by developing hardware and software solutions while also supporting anti-spoofing detection. The developed technology will greatly enhance image quality and preserve privacy. The current very low quality of fingerprint images, in particular as regards damaged fingers, will be overcome by the use of sub-surfacing techniques that will be the main asset for enhancing image quality. This complementarity will permit to deliver high-quality fingerprint images that will still be compliant with programs and applications currently using digital fingerprints as a mean of authentication or identification (EU-Passport, EURODAC, VIS, Entry/Exit, Registered Traveller Program or other European and national applications).

The work on high quality image generation as well as the assessment of image quality that we propose in INGRESS will to warranty that fingerprint quality will be improved during this project, but also to guarantee that images generated will be in accordance with existing projects that will benefit from such a work. Moreover INGRESS intends to deliver with new sensors equivalent image quality as with traditional optical or capacitive sensors. The performance measured during the on-the-field implementation, in terms of ergonomics, speed, error rates and recognition accuracy, will be a good way to determine how relevant the technologies developed throughout the project are and which one will best fit for purpose in border control and law enforcement applications. A combination of technologies (existing and/or developed) to fulfil objectives is not excluded, and will perhaps be necessary to address the issues we will cope with.

At the end of the project, a roadmap will allow an evaluation of the cost and time needed for the production of innovative sensors among the technologies studied. Different levels of maturity allowing a mid-term and long-term planning will then have been reached for the techniques developed, which will make possible the introduction of products on the market on a wider scale. These products will deliver high-quality image under specific constraints defined during the project, with a specific focus on border control and law enforcement applications while being compatible with on-going European programs like EU-Passport or VIS, MS ID cards, EU VIS or EURODAC.

Thanks to INGRESS, more efficient and accurate fingerprint live scanners will have an impact on the quality of life for the citizen who will be able to spend less time in identity checking. Biometrics sub-surface sensors will enable to use eID documents more often and will democratise their use thanks to the very low failure to acquire induced by these sensors. In a broader view, this will make possible to use fingerprints more easily in many areas: electronic identity documents of course, but also credit cards, loyalty cards or future e-documents including fingerprints. The majority of users already see biometrics as convenient With these innovative sensors, it is to be available everywhere for everyone.
