Just days after Sarah Palin’s selection last August as the Republican Vice Presidential candidate, a photo of a bikini-clad, gun-toting Palin blitzed across the Internet. Almost as quickly, it was revealed as a hoax — a crude bit of Photoshop manipulation created by splicing an image of the Alaska governor’s head onto someone else’s body. From start to finish, the doctoring probably took no more than 15 minutes. We review the impact of digital photo manipulation, and recent advances in digital image forensics to detect such manipulations.
