A new Dartmouth study confirms the authenticity of the famous backyard photo of Lee Harvey Oswald holding the same type of rifle used to assassinate President John F. Kennedy.

The findings refute continued claims that the photo was faked because Oswald's pose is physically implausible. The study, which uses a new digital image forensics technique and a 3-D model of Oswald developed by the Dartmouth researchers, appears in the Journal of Digital Forensics, Security and Law. A PDF and photos are available on request.

"Our detailed analysis of Oswald's pose, the lighting and shadows and the rifle in his hands refutes the argument of photo tampering," says senior author Hany Farid, a professor of computer science and a pioneering researcher in digital forensics whose team develops mathematical and computational techniques to detect tampering in photos, videos, audios and documents.
