University of Connecticut researchers led by professor Bahram Javidi want to use quick response (QR) codes to protect national security. They are using advanced three-dimensional optical imaging and extremely low-light photon counting encryption to transform a conventional QR code into a high-end cybersecurity application that can be used to protect the integrity of computer microchips.
The researchers found they were able to compress information about a chip's functionality, capacity, and part number directly into the QR code so it can be obtained by the reader without accessing the Internet, which Javidi says is an important cybersecurity breakthrough because linking to the Internet greatly increases vulnerability to hacking or corruption.
The researchers also applied an optical-imaging mask that scrambles the QR code design into a random mass of black-and-white pixels. Another layer of security is then added through a random phase photon-based encryption, which converts the snowy image into a darkened image with just a few random dots of pixilated light.
