EWADA Statement


Ethical Web and Data Infrastructure in the Age of AI (EWADA) is an ambitious 3-year programme that aims to reform the concentration of power on the World Wide Web by developing and deploying new forms of technical and legal infrastructure.

Thirty years ago, the World Wide Web was launched as an open, common, universal infrastructure that anyone with a computer and a modem could use to communicate, publish and access information. In recent years, however, it has radically diverged from the values upon which it was founded, and it is now dominated by a number of platform companies, whose business models and services generate huge profits. To reform the centralised Web and create “architectures for autonomy”, EWADA aims to investigate novel re-decentralisation architectures and privacy-preserving AI methods and define new institutional and legal constructs that are required in this transformation.


Our work is organised around four themes:

  • Data Autonomy We wish to ensure individuals can control, manage, maintain and use personal data by 1) empowering people with their data; and 2) enabling people to understand and control how, when, and for what purposes data are shared.
  • Data Privacy We will develop a range of privacy-preserving machine learning (PPML) methods that will mean AI training can be decentralised, enabling data to be processed locally, rather than in large, centralised data centres. Processing data in a way that maintains user privacy, prevents subversion of the results whilst still extracting wider collective value.
  • Accountability We will develop methods to assess whether AI or algorithmic decision making is fair, equitable and complies with regulatory requirements, and seek ways to promote a right to explanation of the internal decision-making process of algorithms.
  • Data Sharing We will explore new institutional and legal constructs within which to hold data or algorithmic outputs. We will develop new forms of holding and sharing data through concepts such as data trusts, mutuals or cooperatives. We will also develop architectures that could allow data to be shared in more flexible and innovative ways, respecting individual autonomy while generating wider societal benefits.

The Team


Situated at the Oxford Martin School and the Department of Computer Science at Oxford University, we bring together world leading scholars in AI, ethics & law and innovative minds in privacy perserving AI and decentralised web architectures to create changes and demonstrate the power of a new paradigm.

Meet our team.
