LPW 2022 ‒ The 4th Location Privacy Workshop

Location and mobility data are highly sensitive, as they can be used to infer a number of other personal and sensitive data on an individual. However, human mobility is highly predictable, and location information is routinely collected by location-aware devices (e.g. smartphones), connected vehicles, smart transportation systems, e-tolling, and cameras with face recognition among others.

Location privacy is a rapidly developing research area, and the fourth Location Privacy Workshop (LPW 2022) provides a platform for original research and discussion on all technical aspects of privacy and security of location-based services.


Accepted papers will appear in a volume accompanying the main IEEE Euro S&P 2022 proceedings, published by the IEEE. They will be available on IEEE Xplore and will be indexed by Scopus, dblp, etc.


Topics of interest

  • Security of location-aware mobile devices
  • Privacy-enhancing technologies for location-based services
  • Privacy and anonymity in (public) transportation systems
  • Privacy and security in connected/autonomous vehicles
  • Security of smart mobility applications
  • Privacy in location-aware social media
  • Privacy in position-based advertising
  • Malicious and pervasive tracking, de-anonymization
  • Cryptographic protocols and schemes for location information
  • Data structures for location information
  • Security and reliability of positioning systems
  • Location verification and authentication
  • Location forensics
  • Data protection techniques for regulatory (GDPR) compliance
  • Privacy in location-based contact tracing
  • …and any other related topic

LPW 2022 is co-located with the 7th IEEE European Symposium on Security and Privacy (IEEE Euro S&P 2022). The conference is currently scheduled as an in-person event in Genoa, Italy.

Call for Papers

The Call for Papers is available for download:

Please help us spread the word!


Prospective authors are invited to submit novel contributions, application papers and case studies. Submissions should be 6-8 pages in the double-column IEEE S&P conference format (template below), but longer contributions up to 10 pages will be considered. Short papers and position papers (3-4 pages) are also welcome. Submissions must be anonymous with no author names, affiliations, acknowledgments, or obvious references. Submitted papers will be carefully evaluated based on originality, significance, technical soundness, presentation and clarity of exposition.

All accepted papers will be published on IEEE Xplore in a volume accompanying the main IEEE EuroS&P 2022 proceedings, and will be indexed in Scopus, dblp, etc.

One of the authors of each accepted paper is expected to present the paper at the conference. We are expecting to hold an in-person workshop and that authors will be able to travel to the conference to present their paper, but we will make allowances for remote presentation in cases where authors of a paper have legitimate reasons for which they are unable to attend in person (full registration will be required in any case). We reserve the right to exclude a paper from distribution after the conference, including withdrawal from the IEEE proceedings, if the paper is not presented (in person or virtually).

Submissions are accepted through EasyChair:

Submitted papers must adhere to the IEEE S&P conference proceeding template. We recommend using LaTeX, and suggest you first compile the supplied LaTeX source as is, checking that you obtain the same PDF as the one supplied. Then, write your paper into the LaTeX template, replacing the boilerplate text. Please do not use other IEEE templates.

Wally and friends: Location privacy, anonymity, motivation, and feasibility

Prof. Constantinos Patsakis, University of Piraeus, Greece ‒ homepage

The use of mobile devices having GPS sensors and other hardware identifiers that can be remotely tracked has created many privacy issues. The main issue with the disclosure of location is the context as it allows the extraction of sensitive and personal information which in many cases individuals would not provide. The goal of this talk is to provide an overview of current research lines regarding location privacy, but focus on the main challenge which is the motive. Given the big monetisation potential that location exposure provides, convincing service providers and vendors to adopt privacy-preserving methods, and protocols does not seem to be very fruitful. Therefore, there is a definite need not only to propose nice features but also to provide the proper motive to allow the wider adoption of such methods.

Constantinos Patsakis is currently an associate professor at the University of Piraeus and an adjunct researcher at Athena Research and Innovation Centre. He holds a degree in Mathematics from the University of Athens, Greece and a M.Sc. in Information Security from Royal Holloway, University of London. His PhD was in Computer Security from the University of Piraeus. His main areas of research include cryptography, security, privacy and data anonymization. In the past, he worked as a researcher at the UNESCO Chair in Data Privacy at the Rovira i Virgili University (URV) of Tarragona, Catalonia, Spain, Trinity College, Dublin Ireland, and the Luxembourg Institute of Science and Technology (LIST). He has participated in numerous EU and national funded R&D projects, coordinating two of them in the area of cyber security.
