Notable Experience

With a combined staff experience of over 80 years, and with contacts throughout the biometrics industry, this sector of the business is the “bread and butter” of the company. We have extensive experience in Automated Fingerprint Identification Systems (AFIS), and also have significant experience in facial recognition. We have integrated biometrics technology within large systems (e.g., containing over 30 million fingerprints). Our most notable experience is within the following systems:

The Department of Homeland Security's (DHS, formerly the Immigration and Naturalization Service's) IDENT System.

Under the IDENT Contract, company personnel helped develop several major subsystems for the Immigration and Naturalization Service (INS). The team members were pivotal in the implementation of the pilot system in 1994. Moreover, they were the impetus behind several critical modifications to the initial IDENT architecture, creating system-wide benefits that gave the INS the core capability to expand the system beyond its original scope and meet national demands for security regulations at the nation's borders.


Under the US-VISIT Contract, our staff helped develop a major national security system under an extremely aggressive schedule. The system was initially deployed in 2004. Our engineers helped plan, develop and integrate major components within the system. Additionally, we have drafted new architectures for the system, so that DHS can effectively meet the growing demands placed on the system.

The Department of Justice's IDENT/IAFIS Integration Project

Within the IDENT/IAFIS Contract, our personnel gained in-depth experience in the integration of very large AFISs: DHS's IDENT System and the FBI's Integrated Automated Fingerprint Identification System (IAFIS). Most notably, members of our team assisted in the Systems Engineering work, which resulted in the successful first-time deployment of DHS Workstation to search both IDENT and IAFIS simultaneously.


Our employees have operated in many different roles within biometrics-related projects and therefore have performed many different tasks. Some of these tasks include:

Client/Server Interface Development

Our personnel helped develop the high-level design of client/server interfaces for “live” systems. These interfaces include Web-based interfaces, as well as more traditional client/server systems. We have developed client/server architectures to provide our customers with the capability to make critical server-side upgrades, without affecting the thousands of active client workstations deployed in the field. We have implemented fundamental changes to the underlying architecture of legacy systems, taking advantage of the latest technology, while still maintaining the legacy clients. Thus, we have given our customers the capability to modernize their systems with minimal impacts to the users.

Our personnel have been involved with the detailed coding, testing, and maintenance of these client/server interfaces. Several of the interfaces that we have developed are currently deployed within real-time systems, and support several thousand transactions a day.

Database Schema

As database architects, our personnel have engineered new database schemas for our customers, to create innovative underlying data structures that meet the customers’ changing needs. Our technical staff has been able to integrate the new schemas into the pertinent systems with minimal downtime. In at least one case, the new schema was implemented through several detailed, well-engineered database administration scripts which populated the new database schema while the legacy schema was still on-line. Consequently, our customers have been able to gain the benefits of the new schemas with minimal impacts to the users, which is of particular importance for systems that are operational round-the-clock (as many law enforcement systems are).

Workflow Processes & On-line Transaction Processing (OLTP)

As our customers’ systems grow and result in the creation of new requirements, they have required more robust server workflow architectures. Our team has met these customer requirements by implementing modern object-oriented workflow designs. These architectures have given the customers the capability to quickly modify the business logic embedded within their workflow processing. Thus, the customers have been able to change existing workflow processes and add new transaction types to meet the changing requirements of the user community. Additionally, these new architectures have given the customers the capability to deploy new workflow processes with minimal downtime; this is due to the intentional loose coupling between the workflow processes, the associated database schemas, and the biometric matchers. The architectures were also designed to maximize the processing efficiency of all server-side components.

Currently, our workflow architectures are operational in several systems. These architectures have been recognized as major modifications that gave our customers the capability to effectively meet critical real-time system requirements related to transaction processing throughput.

Biometric Matcher Interface

Our team members have initiated, drafted and maintained Interface Control Documents (ICDs) to provide proper Configuration Management of the interface to third-party biometric matchers. These ICDs have made “matcher integration” a seamless task. We do not build the actual biometric matching algorithms; instead, we build the interfaces to the various biometric matchers, so that our customers can leverage the strengths of each of the corresponding vendors. The interfaces have provided our customers with the capability to take advantage of new technology offered by the various vendors. Moreover, the interfaces have been generic enough to give our customers the option to integrate various products (offered by numerous biometric companies) without causing major disruptions to their systems. Additionally, team members managed the integration efforts between in-house developers and third-party vendors. We have coded several major portions of these interfaces, and have performed detailed testing (including integration testing) of the interfaces.

External System Interfaces

The nature of many of our customers’ systems is to provide a fundamental identification service to the end users. Consequently, several systems interface with our customers’, in order to obtain an absolute identification of the subjects handled by those systems. Thus, by their nature, biometrics-related systems need to be able to accept transactions from a variety of sources and be able to deliver results back to those sources in an effective, consistent and efficient manner. The team members of ProQual-I.T. have been responsible for interfacing with several systems external to our customers. As a result, our team has worked with several other customers and technology teams to glean requirements from them, and help those customers realize the services which our systems can provide. As a result of these efforts, ProQual-I.T. has much experience with customer relations, enhancing our team’s managerial and technical competency.
