British biometric security firm ievo has secured approval for their latest revision of its ievo ultimate fingerprint reader from the CPNI (Centre for the Protection of National Infrastructure).In a statement, Ievo noted that the scanner product is included in the CPNI's trusted Catalogue of Security Equipment (CSE), permitting its use in protecting a wide variety of Government facilities.The firm adds that the ievo ultimate employs multispectral imaging (MSI) technology to scan and capture data.MSI uses multiple light sources to read not only the surface of the skin, but also data points from the subsurface level (up to 4mm deep) of a finger.The different light sources can penetrate levels of moisture and debris present on the skin to read data points below. This advanced method allows for a high number of uniquely identifiable data points to be recognised and used for a more accurate, reliable and efficient verification process.Shaun Oakes, Managing Director of ievo Ltd, commented, “We have been CPNI approved for earlier models for some time, and now we are delighted that the latest improvements to our scanners are also fully approved for UK government use.”
