Lumidigm has developed a multispectral imager that is able to collect additional information from below the surface of the skin. Unlike traditional technology, multispectral imaging technology is not dependent on the quality or authenticity of the fingerprint ridges presented. The Lumidigm sensor can look beyond surface ridges to verify their authenticity and enhance the identifying image.
If a finger with worn ridges presses the platen, the Lumidigm sensor can read the unique unaffected fingerprint under the skin and enhance the image. Similarly, if there is water or “normal” city grime obscuring the surface ridges, or if the finger isn't fully touching the sensor, environmentally robust multispectral imaging technology can enhance the incomplete surface ridge information with data from below the surface of the skin.
The Lumidigm sensor’s spoof detection ability is unique Multispectral imaging technology can detect a fraudulent fingerprint (a “spoof”) easily by measuring the subsurface data (or lack of subsurface data) against known characteristics of living skin. It can even compare subsurface data to surface data to make sure that they are the same.
Thus, multispectral imaging technology is a revolutionary access control system that is vastly superior to conventional fingerprint technologies. Currently deployed systems cannot obtain adequate fingerprints from up to 16% of the population; Lumidigm sensors can reduce that rate to nearly zero
