This invention describes a specialized device for making online transactions more trustworthy. It works by using a hidden coding technique called steganography to uniquely identify and secure the software running on the device, and potentially the device itself. The claims narrow the invention to this specific method of using steganography for software serialization and device identification.
Why it matters: Filed before widespread IoT and software supply chain attacks. The need for tamper-resistant software and device identification has exploded, making steganographic serialization more relevant.
