This makes me wonder if there's a business case for a privacy-preserving identity service which does age verification. Say you have a strong identity provider that you have proven your age to. Just as the 3rd party site could use SSO login from your identity provider, perhaps the identity provider could provide signed evidence to the 3rd party site that asserts "I have verified that this person is age X" but not divu…
1. Most people access online content through either a personal or business broadband service (residential, mobile, or place-of-work).
2. Those services ... bill directly. Which means that it should be possible to specify an age preference for the service account as a whole, and/or subsets of it. The service can specify whether or not age-bounded online services are acceptable or not, as well as specific classes of age-bounded services. E.g., a workplace service would generally allow for >18 access, but might restrict usage of gaming, gambling, pr0n, or related sites. A household might request no age gating at all (all >18 or whatever minimum age is mandated) or several classes of service, say, if adults and children are present.
3. Where it's necessary to specify multiple preferences, multiple network segments could provide this logically (e.g., an IPv6 block with unrestricted and age-gated ranges), with distinct devices being allocated appropriate gateway addresses.
4. Effectively, the connectivity provider then attests for age, without requiring any finer-grained identity disclosure.
Why ...
A. Would this not work?
B. Is it not being generally proposed?
