We show that image head consistency testing is an eective method for detecting digital images that have been modied. On the other hand, when it is not combined with other forensic methods such as double JPEG detection, a high number of altered photos remained undetected. The same can also be claimed about double JPEG detection. When employed separately without conjunction with other methods, the majority of altered photos remained undetected. In this paper, a quantitative study on this topic is carried out. We show that combining various image forensic methods is a must. cav_un_auth*0284374 ISABEL '11 Proceedings of the 4th International Symposium on Applied Sciences in Biomedical and Communication Technologies Barcelona 26.10.2011-29.10.2011 ES 2013 JC 2 PR http://hdl.handle.net/11104/0212097 2011 cav_un_epca*0370269 Proceedings of ISABEL'11 978-1-4503-0913-4 176-1-176-5 Barcelona ACM 2011
