Location Privacy Workshop (LPW) 2021

@ ARES 2021 - TU Wien, Vienna, Austria - August 17-20, 2021


24/02/2021 ‒ The Call for Papers for LPW 2021 has been announced.

LPW 2021 ‒ The Third 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 and smart transportation systems, e-tolling, and cameras with face recognition among others.

Location privacy is a rapidly developing research area, and the third Location Privacy Workshop (LPW 2021) 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 the main conference proceedings (ARES 2021), published by ACM on the International Conference Proceedings Series (ACM ICPS). They will be available on the ACM digital library 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 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 2021 is co-located with the 16th International Conference on Availability, Reliability and Security (ARES 2021). The conference is currently scheduled as an in-person event in Vienna, Austria, but depending on the COVID-19 situation, the conference might be held as an all-digital conference instead, if necessary. In any case, we will offer virtual presentation for authors, if traveling is not possible due to COVID-19.

Perspective authors are invited to submit novel contributions, application papers and case studies. Submission should be 6-8 pages in the double-column ACM conference format (template below). 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 the ACM digital library alongside the main conference proceedings, and indexed in Scopus, dblp, etc.

At least one author of each accepted paper is required to register for the ARES 2021 conference, and present the paper. We reserve the right to exclude a paper from distribution after the conference, including withdrawal from the ACM proceedings, if the paper is not presented by an author (either virtually or in presence, see below) at the conference.

We will offer virtual presentation for authors, if traveling is not possible due to COVID-19. Depending on the COVID-19 situation in 2021, the conference might be held as an all-digital conference, if necessary.

Submissions are accepted through EasyChair (select track LPW 2021):

Submitted paper must adhere to the ACM Primary Article Template: LaTeX (recommended), Word. To ensure compatibility, please check the approved list of LaTeX packages to be used with the template before creating your document. More information is available in the main conference website submission instructions page.
