DENSO Demonstrates Clever New QR Code Image Recognition Technology at #PackExpo

DENSO, the inventor of the QR code, demonstrated image recognition technology at PackExpo this week.   A new and clever approach to image recognition, the technology converts facial recognition data to a special encrypted QR code that can be applied to an ID card for access control or other uses.  The facial image data is embedded in a QR code that is both encrypted and hidden from a standard QR code reader.  

How it works:

A person's image is scanned, and a unique encrypted QR code is created.  (The data is NOT stored on any computer, thus alleviating privacy concerns.)   The QR code can be put on an ID card, for example.    The card can then be used for access say at a secure location, or maybe a kiosk to pick up pharmaceuticals or other restricted items.  The card is scanned at the pick up location and the person's face is then verified to match the encrypted data, so no one can use someone else's card.

 Attempts to scan the QR code with a regular 2D reader will produce a simple message and no encrypted data is readable.  The actual QR code is hidden and not readable by phones or other devices.  

Some uses include ID cards for amusement parks or the unmanned pickup of items like alcohol, marijuana or prescriptions.  The facial image data is not stored anywhere except on the ID card which is a terrific approach and alleviates privacy concerns.  It also allows for remote verification where Internet access may not be available.
