Dr. Reza Ghaffarian is a principal engineer at NASA's Jet Propulsion Laboratory (JPL). DEFECT FEATURES DETECTED BY ACOUSTIC EMISSION Purdue University is leading part of an international effort to develop a system for the military that would detect doc- tored images and video and determine specifically how they were manipulated. The project is funded over four years with a $4.4 million grant from the U.S. Defense Advanced Research Projects Agency (DARPA). The research also in- volves the University of Notre Dame, New York University, University of Southern California, Uni- versity of Siena in Italy, Politecnico di Milano in Italy, and University of Campinas, in Brazil. Edward Delp, Purdue's Charles William Harri- son Distinguished Professor of Electrical and Com- puter Engineering and the director of the Video and Image Processing Laboratory, or VIPER Lab, is the team's principal investigator. The team's co- principal investigators are Walter Scheirer, Kevin W. Bowyer, and Patrick J. Flynn from the University of Notre Dame; Anderson Rocha from the Univer- sity of Campinas in Brazil; C.C. Jay Kuo from the University of Southern Califor- nia; Paolo Bestagini and Stefano Tubaro at Politecnico di Milano in Italy; Mauro Barni at the University of Siena in Italy; and Nasir Memon at New York Univer- sity. A huge volume of images and video of potential intelligence value are up- loaded daily to the Internet. However, visual media are easily manipulated using software tools that are readily available to the public. The research- ers will strive to create an "end-to-end" system capable of handling the massive volume of media uploaded regularly to the Internet, that will auto- matically perform processes needed to verify their authenticity. The aim is not only to verify whether a particular digital object has been tampered with, but also to learn key aspects related to its digital lineage over time, a field known as "multimedia phylogeny". System Might Detect Doctored Images and Videos for the Military
