WebID - W3C Wiki

The W3C is still exploring better ways to do authentication, for example in the 2014 workshop on authentication. The WebID is a Community Group, and anyone can start a Community Group. A Community Group does not necessarily reflect the endorsement of the W3C, but we encourage grassroots communities to experiment with technology that may become a future standard.

C2PA | Providing Origins of Media Content

Enhance digital safety through the use of content authenticity tools. C2PA provides a way to ensure content transparency by analyzing the origin of media.

Attached: 1 image A strong Europe needs independent digital spaces. We believe true digital sovereignty thrives on a competitive, contestable, open ecosystem where diverse platforms co-exist. Today, we’re expanding our presence to W, the new social media. By being on W, we want to boost alternatives and support all efforts toward a decentralised web. And we continue to invest into our presence on the Fediverse!
