Data on an acquisition device and fingerprints are extracted from an image and confronted with a reference data set that includes all possible fingerprints of the acquisition device. This allows us to draw a conclusion whether the digital image has been modified or not. Thus it is critical to have a sufficiently large, reliable, and true reference data set, otherwise critical miscalculations can arise. Reference data sets are extracted from image data sets that in turn are collected from unknown and nonguaranteed environments (mostly from the Internet). Since often software modifications leave no obvious traces in the image file (e.g., in metadata), it is not easy to recognize original images, from which fingerprints of acquisition devices can be extracted to form true reference data sets. This is the problem addressed in this paper. 2014 JC 4 A 4a 20231122135859.1 RVO:67985556 http://hdl.handle.net/11104/0225914 COMPUTERSCIENCETHEORYMETHODS|ENGINEERINGELECTRICALELECTRONIC 2.379 0.227 3.VII 0.00766 0.91 1598 176 1.033 ScienceCitationIndexExpanded Q1 76.163 82.770 Q1 Q1 2013 Soubory v repozitáři: mahdian-0398095.pdf 84882993598 SCOPUS 000324575200010 WOS cav_un_epca*0311611 IEEE Transactions on Information Forensics and Security 1556-6013 1556-6021 Roč. 8 č. 9 2013 1531 1540
