Pseudorandom Thoughts

Link lgf: Reuters Doctoring Photos from Beirut? is quite interesting and brings to mind ideas from over a decade ago of embedding secure, tamper-resistant hardware into digital cameras to digitally sign photos. Without something like that to provide a chain of evidence (when the chain of custody is weak), our faith in photographic evidence should necessarily diminish as photo manipulation gets easier and easier. Of course, photos may need post processing in order to enhance color balance, etc etc, and that's why authenticating that an original raw photo came from a particular camera is only a link in the chain of evidence. After all, shots (like the one with the dead body) can easily be staged. (NB: I have no idea if it was, and if it were, to what degree.)
