The Globe and Mail reports in its Wednesday, Feb. 7, edition that Meta will begin detecting and labelling images generated by other companies' artificial-intelligence services in the coming months, using a set of invisible markers built into the files, its top policy executive said on Tuesday. A Reuters dispatch to The Globe reports that Meta will apply the labels to any content carrying the markers that is posted to its Facebook, Instagram and Threads services, in an effort to signal to users that the images -- which in many cases resemble real photos -- are actually digital creations, the company's president of global affairs, Nick Clegg, wrote in a blog post. Meta already labels any content generated using its own AI tools. Once the new system is running, Meta will do the same for images created on services run by OpenAI, Microsoft, Adobe, Midjourney, Shutterstock and Alphabet's Google, Mr. Clegg said. The announcement provides an early glimpse into an emerging system of standards technology companies are developing to mitigate the potential harms associated with generative AI technologies, which can spit out fake but realistic-seeming content in response to simple prompts.
