On Tuesday, Adobe announced a new symbol designed to indicate when content has been generated or altered using AI tools, reports The Verge, as well as verifying the provenance of non-AI media. The symbol, created in collaboration with other industry players as part of the Coalition for Content Provenance and Authenticity (C2PA), aims to bring transparency to media creation and reduce the impact of misinformation or deepfakes online. Whether it will actually do so in practice is uncertain.
