Google Chrome proposes 'privacy sandbox' to reform advertising evils

Google's Chrome team proposed a "privacy sandbox" that's designed to give us the best of both worlds: ads that publishers can target toward our interests but that don't infringe our privacy. It's a major development in an area where Chrome, the dominant browser, has lagged competitors. Browsers already include security sandboxes, restrictions designed to confine malware and limit its possible damage. Google's proposed privacy sandbox would similarly restrict tracking technology. For example, Chrome would restrict some private data to the browser -- an approach that Brave Software has taken with its privacy-focused rival web browser. And it could restrict sharing personal data until it's shared across a large group of people using technologies called differential privacy and federated learning.
