HANOVER, N.H. — As Hany Farid sat in his office here at Dartmouth College on a recent morning, he fiddled with his laptop and cracked disconcerting little jokes.
‘I Think Like a Forger’ Using computer and mathematical techniques, Hany Farid can tell if the lighting is wrong, the fish isn’t that big or the celebrities weren’t really together.
“Don’t ever send me a photograph of yourself,” said Dr. Farid, head of the Image Science Laboratory at Dartmouth. “I’ll do the most terrible things to it.”
Dr. Farid, a 41-year-old engineer, is a founder of a subdiscipline within computer science: digital forensics. Most days, he spends his time transforming ordinary images into ones with drastic new meanings. Click, goes his mouse. Courtney Love has joined Grandpa at the family barbecue. Click. Click. Elvis Presley is on Dartmouth’s board of trustees.
The purpose of all this manipulation is to discover how computerized forgeries are made. Intelligence agencies, news organizations and scientific journals employ Dr. Farid’s consulting services when they need to authenticate the validity of images. Dr. Farid sells a software package, “Q,” to clients so they, too, can become digital detectives.
An edited version of two hours’ worth of conversation follows.

Digital Memory sure is becoming cheaper and cheaper and cheaper. I'm curious as to when we will eventually hit the rate of 1 cent to 1 Gigabyte.
I'm eagerly anticipating the day when I will finally be able to afford a 20 TB harddrive, hahaha. But for now I guess I will be content with having a 32 gig Micro SD in my R4i.
