We invest heavily in fighting child sexual exploitation online and use technology to deter, detect, and remove CSAM from our platforms. This includes automated detection and human review, in addition to relying on reports submitted by our users and third parties such as NGOs, to detect, remove, and report CSAM on our platforms. We deploy hash matching, including YouTube’s CSAI Match, to detect known CSAM. We also deploy machine learning classifiers to discover never-before-seen CSAM, which is then confirmed by our specialist review teams. Using our classifiers, Google created the Content Safety API, which we provide to others to help them prioritize abuse content for human review.
