Photography lost its innocence many years ago. Shortly after the first commercially available camera was introduced, photographs were being manipulated and altered. With the advent of high-resolution digital cameras, powerful personal computers and sophisticated photo-editing software, the manipulation of digital images is becoming more common. We are seeing the impact of these technologies in nearly every corner of our lives. As the technology that allows for digital media to be manipulated and distorted is developing at break-neck speeds, our understanding of the technological, ethical, and legal implications is lagging behind. I will discuss some of these issues and describe techniques which we have developed for detecting tampering in digital media.
