@dave @mhoye The Swiss government e-ID is basically promising that: verify the age, but without leaving a data trace that can be linked (on either side) to anything. Despite being technically sound (open source and all), the law just barely passed the referendum. I guess the risk is that companies will use more "convenient" ways to verify age, and/or share any verified info they get with their whole ad network, where everything ends up linked with everything else. https://www.eid.admin.ch/en
