Facebook is testing a feature that asks users to opt-in to 'cloud processing', which allows the company to access and analyze their private, unpublished photos from their camera roll. The feature is intended to generate suggestions for content sharing, but the company's AI usage terms do not provide clarity on whether these photos will be used to train AI models. Meta claims that the feature is currently not training AI models with these photos, but the company's history of data scraping and lack of transparency raises concerns. Users can opt-out of the feature and remove their unpublished photos from the cloud after 30 days.
