Title: "Innovative Technology to Detect Digital Photo Manipulation

The transcript discusses a controversy involving an altered photo of John Kerry and Jane Fonda, which was part of a smear campaign. A new technique developed by the University of Roma, Tre, uses holograms and cryptographic methods to detect digital photo alterations. This technique involves embedding an invisible watermark in photos, which can reveal tampering. The system could be widely applied if digital cameras incorporate this technology, helping newspapers verify the authenticity of images. The method allows editors to detect forgery by checking for damaged watermarks.
