"Never" is a long time, and it's plausible the NSA might be interested in a list of names of people who have gone to extremes to hide from them. Is the detection process so difficult that Facebook couldn't integrate it into the upload processing of all new images? There's obviously no need to retroactively check images that were uploaded before your algorithm was written.
- owencm 14y agoThe retrospective scanning is a great point - I hadn't considered that. The detection process is certainly not going to be built into the Facebook upload process unless really serious (and seriously public) usage of these techniques takes off such as wide-spread use by terrorists. But theoretically, yes detecting could be integrated with uploading. That said, steganography algorithms and detectors generally play a cat and mouse game so as long as extension providers can move faster than Facebook in implementing new algorithms this risk is mitigated.
