Want to Stop Online Photo Piracy? Create a Better User Experience | Black Star Rising:
"A few tools are slowly emerging as a reaction to the piracy problem. PicScout, for example, will help you after the fact, as will TinEye. But these are reactions, not solutions.
ImageSpan, GumGum and PicApp offer an option, but not a solution. It doesn’t make much sense for third-party companies to concentrate on such a limited model to pick up a few pennies. It will soon be obvious that there is no room for technology companies like these to wiggle in — not between agencies and their clients at least.
Most copyright owners, meanwhile, are still hoping that metadata will save them, forgetting so conveniently that it can be so easily stripped away."
