Facebook Image Hashing

November 8, 2017

This is a short post. I read “Revenge Porn: Facebook Teaming Up with Government to Stop Nude Photos Ending Up on Messenger, Instagram.” The method referenced in the write up involves “hashing.” Without getting into the weeds, the approach reminded me of the system and method developed by Terbium Labs for its Matchlight innovation. If you are curious about these techniques, you might want to take a quick look at the Terbium Web site. Based on the write up, it is not clear if the Facebook approach was developed by that company or if a third party was involved. Worth watching how this Facebook attempt to deal with some of its interesting content issues evolves.
