    摘要: A reading device reads ambiguous target elements of an authentication target printed on a medium. Each ambiguous target element has a number of different manners by which the ambiguous target element can be interpreted by the reading device. The authentication target as read by the reading device is compared against an authentication signature of the reading device. The authentication signature specifies for each ambiguous target element an expected manner by which the reading device interprets the ambiguous target element as one of the different manners by which the ambiguous target element can be interpreted. Where the authentication target as read by the reading device matches the authentication signature of the reading device, the reading device is signaled as having passed authentication.

    摘要: A system can comprise a memory to store machine readable instructions and a processing unit to access the memory and execute the machine readable instructions. The machine readable instructions can comprise a feature set extractor to extract a feature set from each of a plurality of digital images of print samples. The feature set can be a filtered feature set that includes a feature set characterizing a printer that printed a given print sample of the print samples. The machine readable instructions can also comprise a cluster component to determine clusters of the print samples based on the feature set of each of the plurality of scanned images of the print samples. The machine readable instructions can further comprise a printer identifier to identify the printer of the print samples based on the clusters of the print samples.
