Title: "Innovative Technology to Detect Digital Photo Manipulation

The transcript discusses an incident involving an altered photo of John Kerry and Jane Fonda, which was part of a smear campaign. A new technique developed by researchers at the University of Roma Tre can detect digital alterations in photos by embedding a cryptographic hologram. This technique allows photo editors to verify the authenticity of images by checking for a watermark. If altered, the watermark shows visible damage, indicating tampering. The system could be widely applied if digital cameras incorporate this technology, aiding newspapers and magazines in verifying photo integrity.
