Security at your fingertips
The global biometric revolutionBrunei was one of the first nations in the world to introduce an electronic ID card integrating digital fingerprints. Arrivals in and departures from Singapore are recorded by fingerprint. Twenty-four banks in Nigeria use fingerprint and facial recognition. Thousands of refugees in Germany have been registered with fingerprint scanners.
These examples are just a few of the more than 200 from 80 countries with two things in common: they’re using digital biometric authentication to verify identity, and the technology is coming from the same company – Hamburg’s DERMALOG. The pioneer in biometrics solutions development has been fueling technical progress for over 20 years and today is the largest German supplier in a future market.
World leaders in biometric securitySuch opportunities also invite challenges. The biometric technique is only convincing with flawless, fast detection. This is where DERMALOG specialists excel. Their AFIS (Automated Fingerprint Identification System), for instance, based on independent TÜV analysis, uses a special modular server platform (standard blade server) to compare nearly a billion fingerprints per second – a world record without sacrificing accuracy.
AFIS integrates other applications such as iris and facial recognition to achieve highly secure multibiometric software solutions. DERMALOG hardware such as scanners and e-gates for automatic access control also offers individual and comprehensive solutions for large database applications. “We are a developer, manufacturer and system integrator at the same time, and see ourselves as leaders in innovation,” sums up DERMALOG Managing Director Günther Mull.
Introducing the all-in-one scannerThe company has now developed the world’s first scanner that can read fingerprints, as well as e-passports, signatures, tickets and barcodes on the same scan area. It also enables instant comparison with fingerprints stored in the passports’ RFID chips. “Our all-in-one scanner VF1 combines two devices in one, and is particularly well suited for border controls, banks, and e-gates,” explains DERMALOG Engineer Felix Lüers.
A computer-aided manual, for instance, walks users through correctly placing their fingers, which are recorded in seconds – automated self-registration without any staff. Sensor technology enables live detection, preventing mistakes and deceptions, and literally ensures safety to the fingertips.
The optical system with high scan resolution uses CONTURAX® glass from SCHOTT for homogeneous illumination of the touch surface. "A wise choice," says Felix Lüers.
High-intensity scan with quality glassThe lighting unit of DERMALOG’s optical fingerprint and document scanner VF1 initially consists of a printed circuit board with three LED types. These radiate in a spectral range from ultraviolet to near-infrared, bandwidths which allow security features to be optically read from electronic ID cards. Two glass components from SCHOTT above the LEDs ensure homogeneous illumination. A frosted glass diffuses the emitted light, which is then broken by two overlying cylindrical collecting lenses made of CONTURAX® profiled glass. Light rays finally hit a prism whose surface forms the touchpad for fingers or e-passports.
More reliable biometrics of the futureBiometrics, the science of measuring and analyzing biological characteristics, is considered much safer than PIN numbers and passwords. But is that correct? The European Chaos Computer Club seemed to prove the opposite when it hacked fingerprints and irises of German politicians in 2014.
However, the safety and reliability of biometric procedures increase with the quality of biometric features and comparison data, the performance of the sensor and the computing capacity of the system. System manufacturers are also working on live recognition in features to foil forgery. Functioning live tests already exist for fingerprints, irises, faces and veins. High-performance sensor technology and special software, for example, detect the smallest movements and other living signals or detect non-living materials. The effort focuses on machine-learning processes.
“We’re heavily focusing on these topics to remain at the forefront of accuracy and speed, and to be compliant with current standards such as ISO/IEC 30107,” says DERMALOG Developer Daniel Hartung.
Multibiometric procedures also boost security. Several features are simultaneously measured and compared, including fingerprints and irises. But the future could also belong to features considered “forgery-proof”. Methods are already being tested that recognize individual movement patterns such as walking speed, length of stride, and hip movements. And that’s only the beginning: research is also underway on features such as DNA, body odor, and salinity.
