Semantic Forensics (SemaFor)
Abstract
The Semantic Forensics (SemaFor) program, building on technologies introduced in MediFor, will develop technologies to defend against the falsification of multimedia and disinformation campaigns. Statistical detection techniques have been successful, but media generation and manipulation technology is advancing rapidly, and purely statistical detection methods are now insufficient. Existing media generation and manipulation algorithms are data driven and are prone to making semantic errors that provide defenders an opportunity for asymmetric advantage. SemaFor will create semantic and statistical analysis algorithms that determine if media is generated or manipulated; attribution algorithms that infer if media originates from a particular organization or individual; and characterization algorithms that reason about whether media was generated or manipulated for malicious purposes. SemaFor aims to create technologies to identify, deter, and understand adversary disinformation campaigns.
