Abstract
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. While 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 computational
techniques which we have developed for detecting tampering in digital
media. Operating in the absence of digital watermarks or signatures,
these techniques quantify and detect statistical correlations that
result from specific forms of digital tampering.
