  • Patent number: 8406480
    Abstract: A solution for visual credential verification. The solution includes an apparatus, system, and method embodiment. The apparatus for visual credential verification includes an input module, a comparison module, and a response module. The input module receives from a security official an image of an unverified credential, such as a badge, that an individual has presented to the security official. The comparison module determines whether or not the unverified credential is valid or invalid. The determination includes comparing the image of the unverified credential with known good images of valid credentials. The comparison module may also compare authentication information such as a photo of the individual, a name, or a badge number, with known good authentication information. Based on the comparison module's determination, the response module notifies the security official that the unverified credential is either valid or invalid.
