Researchers at the University of Rochester have developed a new form of QR code, known as self-authenticating dual-modulated QR (SDMQR), that aims to protect smartphone users from potential phishing attacks while scanning QR codes. These attacks, known as “quishing,” involve cybercriminals directing users to fake websites to steal sensitive information.
The SDMQR codes allow official sources to pre-register their URLs and embed a cryptographic signature in the QR code. When a user scans the code, the decoder can signal whether the link is safe or potentially harmful. The added security layer does not disrupt the functionality of QR codes and aims to prevent users from falling victim to scams.
The researchers have also explored opportunities to commercialize the technology, including replacing traditional UPC barcodes with these more sophisticated QR codes. The codes can use different shapes and colors to embed more information and drive users to multiple destinations.
Companies have shown interest in the technology as it allows for branded codes on packaging, which can replace traditional UPC barcodes and provide more information in a smaller area. The SDMQR codes offer a more secure and efficient alternative to traditional QR codes and have the potential to revolutionize the way companies utilize barcodes for product identification.
The researchers have filed a patent for the technology and secured a grant to explore industry applications. By enhancing the security and functionality of QR codes, the technology has the potential to protect users from cyber threats and provide companies with a more advanced method of product identification.
