The Brussels Privacy Hub is organizing on September 26, 2018, a “by invitation only” workshop, under the Chatham House Rule, on data analytics processing by Telecommunications Operators, as affected by the draft ePrivacy Regulation and the GDPR. The workshop builds upon accumulated know-how of two past events, on December 7, 2017 and February 22, 2018, respectively. Its aim will be to discuss whether a new industry guideline could address current concerns and difficulties. Participants will come from academia and the industry.
