The innovative technologies developed in FP7 INGRESS project, which was conducted by TĂśBÄ°TAK BÄ°LGEM UEKAE e-ID Technologies Department as a partner of the â€śFP7 INGRESSâ€ť project in European Union 7th Framework Program (FP7) Security call, took place in NASAâ€™s periodical Tech Briefs.
A new technology based on optical coherence tomography (OCT) which was developed with the project partner CNRS (France) enables subsurface imaging of the finger. The very first prototype of the OCT fingerprint reader was included in the â€śFP7 INGRESS First Data Collectionâ€ť campaign which was carried out by TĂśBÄ°TAK BÄ°LGEM UEKAE e-ID Technologies Department between October-November of 2015. In this campaign, fingerprint images of 176 volunteers were captured and analyzed. The valuable feedback of this study is planned to be used for further development of OCT technology.
Experience shows that two main kinds of fingerprint alterations can be observed: voluntary (intentional) and involuntary (unintentional). In the first case, surgical or physical alterations are intentionally created to modify the friction ridge skin and prevent its recognition by automatic systems. In the case of involuntary alterations, it appears that some types of disease or medical treatments can cause severe injuries of the dermis and of the epidermis, sufficient enough to prevent the capture of the fingerprints for some time. Moreover, some professional activities (especially manual workers, housewives, farmers, etc.) can cause a temporary or permanent absence of fingerprint patterns due to physical abrasions of the fingertip skin. The market for this kind of technology is wide, but the most obvious applications areas would be border control, law enforcement, or other sectors where large numbers of passersby need to be identified. The â€śinternal fingerprintâ€ť could provide cheaper, more secure authentication than traditional scanners.
â€śFP7 INGRESS Data Collectionâ€ť campaign will be conducted in three separate sessions. The second data collection session is going to be held between May-June of 2016 at TĂśBÄ°TAK BÄ°LGEM UEKAE e-ID Technologies Department.
