Title (EN) FORENSIC VERIFICATION FROM HALFTONE IMAGES
(FR) VÉRIFICATION JUDICIAIRE À PARTIR D'IMAGES EN DEMI-TEINTES
Abstract: front page image
(EN)A forensic verification system (900) extracts a print signature via a print signature extractor (910) from a captured image of a printed halftone. The system (900) utilizes a comparator (920) to compare the print signature to a reference signature stored in a registry to determine differences between the print signature and the reference signature. The system (900) utilizes a forensic analyzer (930) to perform a forensic analysis on the signatures based on the comparison to authenticate the printed halftone.
(FR)Un système de vérification judiciaire (900) extrait une signature imprimée au moyen d'un extracteur de signature imprimée (910) à partir d'une image capturée d'une demi-teinte imprimée. Le système (900) utilise un comparateur (920) pour comparer la signature imprimée à une signature de référence enregistrée dans un registre pour déterminer les différences entre la signature imprimée et la signature de référence. Le système (900) utilise un analyseur judiciaire (930) pour effectuer une analyse judiciaire sur les signatures d'après la comparaison pour authentifier la demi-teinte imprimée.
