Small spectroscopic sensor looks at skin
Biometric identification or verification of an individual requires a close look at and analysis of one or more unique body characteristics. These can include fingerprints, the pattern of an iris, or the geometry of a face.
The technology behind the sensor was discovered serendipitously during collaboration between Johnson & Johnson (New Brunswick, NJ) and InLight Solutions Inc. (Albuquerque, NM) aimed at developing a noninvasive optical technique for measuring glucose levels in the living human body. The technique combined spectroscopic measurements of tissue with mathematical analysis. The researchers discovered that, as a result of individual differences in skin makeup, each person has a unique characteristic spectrum. The finding spurred the formation of Lumidigm Inc. (Albuquerque, NM), which will exploit the technology specifically for biometrics.
