Livescan Fingerprint Collection with Silicone Membranes
Current Scenario: Livescan instruments must be able to collect fingerprints from a wide cross section of people—including those with very fine, worn, scarred or cracked fingerprint ridges and varying degrees of skin moisture content. Most systems are optimized for individuals with well-defined ridges on their fingers and sufficient moisture content in their hands. In general, younger people fit this description and have little or no trouble with their fingerprints being captured on any certified scanner. However, problems arise when fingers are too wet or too dry.
Tomorrow's Technology Today: Cross Match Technologies, Inc. has developed a patent-pending silicone membrane technology that greatly improves the collection of fingerprints through livescan systems. The use of a silicone membrane enhances the fingerprint image regardless of skin condition—requiring less finger pressure to capture a print. The result is less distortion of the fingerprint platen and a more accurate, high-quality image.
During the fingerprint collection process, if a subject’s hands are wet, which does not occur naturally under normal operating circumstances, the simple and obvious remedy is to require the subject to dry his or her fingers. Competing livescan systems use a small angled prism design, which is tolerant of wet hands; however, it has limited effect on enhancing the captured image.
To address the most common of moist finger issues—when warm hands are applied to a cold livescan platen causing condensation “halos”—Cross Match livescan systems automatically heat the surface a few degrees above ambient temperature, thereby raising the dew point and preventing condensation halos. This is achieved utilizing silicone membranes, which not only address moist finger issues but the more significant and frequent dry finger issue.
The research and development team at Cross Match determined that using a silicone membrane on the fingerprint capture surface of livescan systems successfully addresses the most significant challenges facing high-volume fingerprint capture. Although a silicone membrane is not required for proper livescan operation, it does uniquely address the most significant obstacles to rapidly collecting high-quality ten-print images from a large cross section of people. As such, silicone membranes represent a significant competitive advantage for the Cross Match suite of livescan ten finger and palm print systems.
Conclusion: Cross Match has developed patented livescan technologies that maximize the advantage of using patent-pending silicone membranes. A cost-effective, low-maintenance solution to combat the difficulties of capturing fingerprints from dry skin, silicone membranes are the proven advantage to increasing fingerprint image detail and eliminating rejections due to insufficient biometric data.
