Desarrollo de Soluciones Biometricas a la Medida y Aplicaciones Diversas

Nowadays the need for automated biometrical identification systems is increasing in civil and forensic fields of applications. The fast and accurate identification becomes particularly critical for large-scale applications, such as passport and visa documentation, border crossings, election control systems, credit card transactions control and crime scene investigations. Many countries, including the US, European countries and others incorporate biometrical data into passports, ID cards, visas and other documents for using in large national scale automatic biometrical identification systems.

Automated fingerprint identification systems (AFIS) have been widely used in forensics for the past two decades, and recently they became relevant for civil applications. Whereas large-scale biometrical applications require high identification speed and reliability, multi-biometric systems that incorporate both face and fingerprint recognition offer a number of advantages for improving identification quality and usability.

Large-scale automatic biometrical identification systems have a number of special requirements, which are different from those for small or middle scale biometrical systems:

• The system must perform reliable identification with large databases, as biometrical identification systems tend to accumulate False Acceptance Rate with database size increase and using single fingerprint or face image for identification task becomes unreliable for large-scale application. Several biometrical samples should be used to increase identification reliability, and multi-biometrical technologies (i.e. collecting fingerprint and face samples from the same person) are often employed there for additional convenience.

• The system must show high productivity and efficiency, which correspond its scale:

  • System scalability is important, as the system might be extended in the future, so high productivity level should be kept by adding new units to the existing system.
  • Daily number of identification requests could be very high.
  • Identification request should be processed in a very short time (ideally – in real time), thus high computational power is required.
  • Support for large databases (tens or hundreds millions of records) is required.
  • General system robustness. The system must be tolerant to hardware failures, as even temporary pauses in its work may cause big problems taking into account the application size.
• The system must support major biometrical standards. This should allow using the system generated templates or databases with the systems from other vendors and vice versa.
• The system must be able to match flat (plain) fingerprints with rolled fingerprints, as many institutions collect rolled fingerprint databases.
• The system must be able to work in the network, as in most cases client workstations are remote from the server with the central database.
• A forensic system must be able to edit latent fingerprint templates in order to submit latent fingerprints into AFIS for the identification.

Despite all these requirements, the system price should be as low as possible. Many existing AFIS are specialized for criminalistics or other particular applications and are quite expensive. Deltacompany.us offers a technology for large-scale AFIS and multi-biometric face-fingerprint identification products, which meets all of the requirements mentioned above, for a competitive price.

Why US?

Deltacompany.us has experience in collaborating with many biometrical system integrators, who develop large-scale biometrical systems. To address their requirements, the company has developed the AFIS GS multi-biometrical technology, intended for large-scale face-fingerprint systems and AFIS integrators. AFIS GS has a set of specific features, which make it very attractive for large-scale biometric system developers:

• Multibiometrics. AFIS GS includes fingerprint and facial recognition engines and allows integrators to use fused algorithm for better identification results or any of these engines separately. Identification reliability is a very important requirement for a large-scale system, thus usually two or more different biometrical samples from the same person are used to increase recognition reliability. Using AFIS GS multi-biometric technology, developers and integrators can create systems where both face and fingerprint can be scanned at the same time using inexpensive hardware, such as a fingerprint scanner and a simple webcam or photo scanner (for example, scanning a passport photo).
• Reliability. As AFIS GS uses fusion of facial and fingerprint recognition results, the identification reliability is very high even when using large databases with millions of records. These ROCs show that large-scale automated biometrical identification system based on AFIS GS provides high identification reliability when using fingerprints, and using multi-biometrical identification results in significant reliability increase, allowing to reach almost 0% FRR.

• Matching speed. AFIS GS is able to match up to 400,000 templates per second running the fused algorithm on a stand-alone PC with 3GHz CPU. MegaMatcher's facial recognition engine is able to match up to 500,000 faces per second, and the fingerprint recognition engine matches up to 60,000 fingerprints per second. The matching speed could be significantly increased by using the PC-based cluster.

• AFIS GS includes cluster software for performing parallel matching, which allows to reach high performance, high availability and efficiency:

  • The effective matching speed increases proportionally to the number of the cluster's nodes and can be scalable to achieve the necessary system performance. For example, a cluster-based multi-biometrical identification system with 10 nodes is able to match up to 4,000,000 records per second, a cluster with 100 nodes - up to 40 millions records per second etc. Such scalable architecture allows to keep up the fast system response if its size becomes larger.
  • A large number of identification requests could be processed by the cluster-based multi-biometrical system. Suppose, there is a database with 10 million records. A cluster with 10 nodes (PCs with 3GHz CPU) will be able to process about 30,000 requests per day with the given database, a cluster with 20 nodes – about 60,000 requests per day and so on.
  • Fast request processing. The scalable cluster architecture for automated biometrical identification system allows to achieve real-time processing of the identification request.
  • The cluster is able to handle databases of a practically unlimited size.
  • Computer cluster is fault-tolerant, so in case of a cluster node fault, the matching speed slightly decreases, but the cluster's work remains uninterrupted.

• AFIS GS supports BioAPI 2.0 (ISO/IEC 1978-1:2006) and other biometrical standards:

  • ISO/IEC 19794-2 (Information technology – Biometric data interchange formats – Part 2: Fingerprint minutiae data)
  • ISO/IEC 19794-4 (Information technology – Biometric data interchange formats – Part 4: Finger image data)
  • ISO/IEC 19794-5 (Information technology – Biometric data interchange formats – Part 5: Face image data)
  • ANSI INCITS 378-2004 (Finger Minutiae Format for Data Interchange)(ANSI378)
  • ANSI INCITS 381-2004 (American National Standard for Information Technology – Finger Image-Based Data Interchange Format)
  • ANSI INCITS 385-2004 (American National Standard for Information Technology – Face Recognition Format for Data Interchange)
  • ANSI/NIST-ITL 1-2000 (Data format interchange of Fingerprint, Facial, and Scar Mark and Tattoo (SMT) Information) (AN2K)

  Therefore, AFIS GS fingerprint templates could be exported to another identification system and vice versa. Additionally, AFIS GS supports WSQ fingerprint image storage format.

• The technology allows to match rolled and flat fingerprints between themselves. Usually conventional "flat" fingerprint identification algorithms perform matching between flat and rolled fingerprints less reliably due to the specific deformations of rolled fingerprints. AFIS GS allows matching of flat-flat, flat-rolled or rolled-rolled fingerprints with high reliability.
• AFIS GS includes network support, as components of AFIS GS are intended to be distributed on the network.
• Effective price/performance ratio. AFIS GS uses a PC and can work with Microsoft Windows and Linux operating systems. This configuration provides the most price/performance effective computational units for all components of the system.
