Hany Farid is a professor of computer science at Dartmouth College and former chair of Dartmouth's Neukom Institute for Computational Science. Farid specializes in image analysis, human perception, and has been called the "father" of digital image forensics by NOVA scienceNOW.[1][2] The recipient of a 2006 Guggenheim Fellowship and a 2002 Sloan Fellowship for his work in the field,[3] Farid has consulted for intelligence agencies, news organizations, courts, and scientific journals seeking to authenticate the validity of images.[4][5][6] This is critically important because graphics programs, such as Photoshop, are frequently used to crop and to label figures in scientific publications. Such manipulations can be used to alter or disguise the data. In 2009, after digitally analyzing a photograph of Lee Harvey Oswald holding a rifle and newspaper, Farid published his findings[7] concluding that "the photo almost certainly was not altered".[8] When the 2012 World Press Photo of the Year was alleged as being "fake", Farid spoke out against the allegation and criticized its underlying method, error level analysis.[9]

He received his B.S. in computer science and applied mathematics from the University of Rochester in 1989. He received his Ph.D. in computer science from the University of Pennsylvania in 1997.[3]

Proposed agency

In 2016, Hany Farid proposed that the PhotoDNA technology he developed with Microsoft could be used to stem the spread of terror-related imagery, but there has been little interest shown initially by social media companies.[10] Farid proposes an information clearinghouse called the National Office for Reporting Extremism (NOREX).
