From Technology Review‘s’ “Face Forward“:
To get around these problems, OmniPerception, a spinoff from the University of Surrey in England, has combined its facial-recognition technology with a smart-card system. This could make face recognition more robust and better suited to applications such as passport authentication and building access control, which, if they use biometrics at all, rely mainly on fingerprint verification, says David McIntosh, the company’s CEO. With OmniPerception’s technology, an image of a person’s face is verified against a “facial PIN” carried on the card, eliminating the need to search a central database and making the system less intimidating to privacy-conscious users. …
OmniPerception’s technology creates a PIN about 2,500 digits long from its analysis of the most distinctive features of a person’s face. The number is embedded in a smart card-such as those, say, that grant access to a building-and used to verify that the card belongs to the person presenting it. A user would place his or her card in or near a reader and face a camera, which would take a photo and feed it to the card. The card would then compare the PIN it carried to information it derived from the new photo and either accept or reject the person as the rightful owner of the card. The technology could also be used to ensure passport or driver’s license authenticity and to secure ATM or Internet banking transactions, says McIntosh.
