Newsom Signs Calif. AI Bills on Watermarks, Sexually Explicit Deepfakes

California Gov. Gavin Newsom (D) signed three more AI bills, bringing the total number to eight this week. The governor’s office said Thursday that Newsom signed SB-942, which requires widely used generative AI systems to add invisible watermarks to content so that it can be easily identified as AI-generated. The governor also signed SB-926, making it illegal to create sexually explicit deepfake images of a real person, and SB-981, requiring social media platforms to establish a way for users to report sexually explicit deepfakes of themselves. On Tuesday, he signed five AI bills related to elections and entertainment (see 2409180024). Newsom has yet to sign a controversial AI bill (SB-1047) that would require large AI developers and those providing computing power to train AI models to implement protections preventing critical harms (see 2409060039). The governor has until Sept. 30 to sign or veto bills that the legislature passed this year.
