World Wide Web Consortium

The World Wide Web Consortium (W3C) was established in 1994 by Web inventor Tim Berners-Lee, to develop interoperable standards to lead the Web to its full potential.

We are an international multi-stakeholder community where member organizations, a full-time staff, and the public work together to build a Web based on the principles of accessibility, internationalization, privacy and security.

Please be more curious than critical. Your interactions go to real people who care and do their best 🙏

The Privacy Working Group has published the first draft of a Group Note titled Considerations for Reviewing Differential Privacy Systems (for Non-Differential Privacy Experts). The purpose of this document is to provide a high level understanding of the trade-offs that are required when designing and deploying differentially private systems (e.g., privacy, utility, number of trusted parties).

Galloping into the Lunar New Year with W3C! Speed of the horse, sustainability of the standard. With the spirit of the horse — endurance, strength, and forward momentum — we wish our community a fast, energetic, and federated Year of the Horse.

Thank you for making the web open and powerful. The best path is the one we pave together. 马到成功!🐎
