Biometric fingerprint readers have become increasingly important to the security of entities in both the public and private sectors, offering an efficient solution to traditional personal screening methods that can often be plagued by slow processing times and human error. While fingerprint sensors have certainly developed and improved since their introduction to the public market in the late 1960’s, many of today’s standard optical and silicon sensors have high false-negative and failure-to-enroll (FTE) rates, translating into low return on investment (ROI) and poor user satisfaction.
Conventional readers, which sense the surface ridge pattern of the skin by using total internal reflectance (TIR) technology, struggle to produce accurate, clear images in harsh environments. Furthermore, they are prone to “spoofing”, or being deceived into believing that the present finger is authentic, when in fact it is a synthetic rendition.
Multispectral imaging refers to a revolutionary new type of fingerprint recognition technology wher
eby sensors use information from an “internal fingerprint”, or patterned capillaries located approximately 2mm below the skin. The sensor collects images generated from unique polarization techniques and different illumination wavelengths passed through skin, and combines these with the traditional TIR images of the “surface fingerprint”. The result is a consistently high-quality, reliable and accurate fingerprint image.
Lumidigm, a New Mexico, USA based industry pioneer in the field of MSI, has incorporated its patented MSI technology into its J-Series (J-100 and J-110) multispectral fingerprint sensors. Through the use of MSI, Lumidigm’s ruggedized J-Series sensors produce clear, 500 dpi fingerprint images. Encased in a lightweight aluminum body, the J-Series can stand against direct sunlight, rain, cold, hot and humid climates. MSI is coupled with traditional TIR to capture nine different fingerprint images in less than one second, thus allowing for accuracy and “liveness detection”, or the ability to discern between a living finger and a synthetic material.
Lumidigm’s J-Series MSI fingerprint detectors provide some of the industry’s most precise fingerprint images. Their anti-spoofing, weather-resistant qualities are ideal for outdoor installations with conditions such as extreme hot and cold (-28-21° C), direct sunlight, rain, and the chafed or dirty fingers of employees and contractors.
