Abstract
A method of authenticating an object using optically decodable encoded images is presented. The method comprises attaching a digital data storage medium to the object and storing an optically decodable digital encoded image in the data storage medium. The digital encoded image comprises authentication information determinable by decoding the digital encoded image. The method further comprises downloading the digital encoded image from the digital data storage medium and applying a digital decoding algorithm to the captured digital image to establish a decoding result. The decoding result is then compared to object authentication criteria to establish an authentication result.
