Abstract

Multimedia forensics can be defined as the science that tries, by only analysing a particular digital asset, to give an assessment on such a content and to extract information that can be useful to address and support an investigation linked to the scene represented in that specific digital document. The basic idea behind multimedia forensics relies on the observation that both the acquisition process and any post-processing operation leave a distinctive imprint on the data, as a sort of digital fingerprint. The analysis of such a fingerprint may permit to determine image/video origin and to establish digital content authenticity.
