Online platforms today are being used in deplorably diverse ways: recruiting and radicalizing terrorists, buying and selling illegal weapons and underage prostitutes, cyberbullying and cyberstalking, revenge porn, theft of personal and financial data, propagating fake and hateful news, and much more. Technology companies have been and continue to be frustratingly slow in responding to these real threats with real consequences. I advocate for the development and deployment of new technologies that allow for the free flow of ideas while reining in abuses. As a case study, I will describe one such technology â photoDNA â that is currently being used in the global fight against child exploitation. I will also describe the technological, legal, and policy obstacles that we faced prior to deployment and how lessons from this work can inform future efforts. I will also describe ongoing efforts in countering extremism online.
