摘要: Methods and systems for detecting changes, alterations forgeries in documents utilize digital fingerprinting. A set of a given type that are known to be altered or scanned “fingerprinted” build forgery database. Suspect the resulting fingerprint data is used query database look matching records, although match need not exact. Matches may counted compared threshold number assess confidence document forged not. The fingerprinting directed at least one authentication region document, more features incorporated into document.
