ISR-affiliated Associate Professor Min Wu (ECE/UMIACS) is the co-PI for a three-year grant from the Air Force Office of Scientific Research (AFOSR) for theories and algorithms to perform non-intrusive forensic analysis on multimedia devices and digital content.
Former ISR faculty member K.J. Ray Liu is the principal investigator (PI).
As multimedia devices and digital content have become ubiquitous, a critical issue that must be addressed next is to ensure that content, devices, and intellectual property are being used by authorized users for legitimate purposes, and to be able to forensically prove with high confidence when the case is otherwise. The faculty will exploit intrinsic fingerprints, which are inherent traces left by various processing steps when media data goes through acquisition devices and processing systems. The goal of this research effort is to develop a holistic forensic framework to gather traces of evidence and answer who has done what, when, where, and how.
