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 digital cameras, powerful personal computers, and sophisticated photo-editing software, the manipulation of digital images is becoming much more common. We are seeing the impact of these technologies in nearly every corner of our lives. I will describe computational techniques that we have developed to detect tampering in digital media. Operating in the absence of digital watermarks or signatures, these techniques detect statistical correlations that result from specific forms of digital tampering.

Anyone outside NIST wishing to attend must be sponsored by a NIST employee and receive a visitor badge. For more information, call Kum J. Ham at 301-975-4203.
