Forensic Verification Utilizing Halftone Boundaries

摘要

A forensic verification system (700) extracts a print signature via print signature extractor 710 from the boundary of a halftone contained in an image. The system (700) compares the print signature to a reference signature stored in a registry via comparator 720 to determine differences between the print signature and the reference signature. The system 700 performs a forensic-level statistical image analysis via forensic analyzer 730 on the print signature and the reference signature based on the comparison to authenticate the printed media.

主权项

1. A computer readable medium comprising computer executable instructions that when executed cause a processor to:
extract a print signature from a boundary of a halftone of an image of printed media; compare the print signature to a reference signature stored in a registry to determine differences between the print signature and the reference signature; and perform a forensic-level statistical image analysis on the print signature and the reference signature based on the comparison to authenticate the printed media.
