Oscar-winner Matthew McConaughey has trademarked his image and voice to protect them from unauthorised use by artificial intelligence (AI) platforms. Clips including his famous catchphrase alright, alright, alright from the 1993 film, Dazed and Confused, have been registered to the United States Patent and Trademark Office database, the Wall Street Journal (WSJ) reports. It is the first time an actor has attempted to use trademark law to protect their likeness from AI misuse, his lawyers and an expert said. Stars across Hollywood and the music industry including Scarlett Johansson and Taylor Swift have endured a wave of fake video, audio and images online, created by AI tools. Lawyers for the Magic Mike star told the WSJ they had no current examples of McConaughey's likeness being manipulated by AI, but hoped the trademarks could be used broadly against any unauthorised copies of him.

Elon Musk's AI model Grok will no longer be able to edit photos of real people to show them in revealing clothing, after widespread concern over sexualised AI deepfakes in countries including the UK and US. We have implemented technological measures to prevent the Grok account from allowing the editing of images of real people in revealing clothing such as bikinis. This restriction applies to all users, including paid subscribers, reads an announcement on X, which operates the Grok AI tool. The change was announced hours after California's top prosecutor said the state was probing the spread of sexualised AI deepfakes, including of children, generated by the AI model. The update expands measures that stop all users, including paid subscribers, editing images of real people in revealing outfits.
