PrivaWeb Workshop

The first PrivaWeb workshop aims at gathering the European research community who works on privacy and data protection and to offer them a privileged forum to present and exchange their ideas on this topic. The workshop is multidisciplinary, and in particular legal scholars, economists and and computer scientists are going to participate.

The 2-day workshop takes place form May 22  (arrival May 21 in the evening) to May 23, at Inria Sophia Antipolis (France).

The specific goal of this year’s PrivaWeb edition is to establish a dialog between the legal scholars working on GDPR and ePrivacy Regulation and computer scientists working on Web tracking detection. The four major topic are going to be covered at the workshop:

  1. Detection of Web Tracking: detecting ID cookies and other stateful technologies
  2. GDPR and ePrivacy Regulation: consent requirements on tracking technologies and cookie banners
  3. Requirements for tools to detect Web tracking.
  4. Subject Access Requests, its implementation on the Web and how to improve it
