Governments have long doctored photos for political reasons. Now, thanks to digital technology, image manipulation is available to everyone, and nefarious uses are becoming far more widespread. In around one in 75 insurance claims, photos documenting property damage have been fraudulently retouched, says Eugene Nealon of Nealon Affinity Partners, a company based in London that advises insurers. Liz Williams, editor of the Journal of Cell Biology, says her publication rejects around 1% of peer-reviewed scientific papers after discovering that microscope images have been doctored to make results look good. Many fakes are obvious. But unmasking a sophisticated forgery can require hiring an expert for days, says Hany Farid, professor of image forensics at Dartmouth College in New Hampshire, who sometimes acts as an expert witness. Efforts to automate the detection of doctored images are bearing fruit.
