PriCom 2019

The 5th International Symposium on Privacy Computing

19-21 August 2019, University of Kent, Canterbury, UK


All sessions will take place at Sibson LT2 (on the 1st floor), located in the Sibson Building, on the Canterbury campus of the University of Kent. The buffet lunches will be served in the Sibson Atrium (on the ground floor).

There are two different types of talks: 30-min long talks and 10-min short talks. Long talks are allocated 30 mins including Q&A, so we recommend that the speaker should use 25 mins for the presentation and leave 5 mins for Q&A. Short talks are allocated 10 mins in total, and we recommend that the speaker should use 7-8 mins for the presentation and leave 2-3 mins for quick questions and answers. Session chairs are recommended to collect slides and load them to the computer in the lecture theatre before hand to help save time.

Day 3: 21st August, 2019

The third day of the conference is designed to be a day for group discussion and brainstorming. Participants will be split into smaller "special interest groups" focusing on different sub-topics in order to encourage new collaborations between participants and to generate new research ideas. The conference will help facilitate such group discussions in a flexible and friendly settings. Some recommended sub-topics include (more are welcome from participants at the conference):

  • Privacy metrics and privacy risk assessment
  • Privacy-preserving computing
  • User-centric privacy protection
  • Privacy protection in blockchains and cryptocurrencies
  • Privacy in IoT
  • Privacy and AI
  • GDPR and beyond: legal aspects of privacy (data) protection
