QR(quick response) code are those which are usually in black and white boxes that people scan with their mobile phones to download or to know more about something.The researchers from the University of Connecticut says that these can even take care of national security.
Board of Trustees Distinguished Professor Bahram Javidi said that “An optical code or QR code can be manufactured in such a way that it is very difficult to duplicate,”. “But if you have the right keys, not only can you authenticate the chip, but you can also learn detailed information about the chip and what its specifications are" he added.
Used computer chips doesn't matter much when in the case of poor cell phone reception or an laptop computer crash in personal use, but the problem becomes exponentially more serious when counterfeit or hacked chips turn up in nation's military force.
Unlike commercial QR codes, Javidi’s little black and white boxes can be scaled as small as microns or a few millimeters and would replace the electronic part number that is currently stamped on most microchips.
Javidi also says that he can compress vital information about a chip i.e its functionality, capacity and part number, directly into the QR code so that it can be obtained by the reader without having access to the internet, and this is important in cybersecurity circles, because by linking to the Internet means great increase chances of hacking or corruption.
Javidi has also applied an optical imaging mask which scrambles the QR code design into a mass of black and white pixels which looks similar to the images seen on a broken television, to ensure proper security. He then added another layer of security through a random phase photon based encryption that turns the snowy image into a darkened night time sky with just a few random stars or dots of pixilated light.
The end result of all these layering is a highly secure, microscopic design that is next to impossible to duplicate. Only the individuals with special corresponding codes can decrypt the QR image.
