GeoPrivacy 2023

1st ACM SIGSPATIAL International Workshop on Geo-Privacy and Data Utility for Smart Societies 

 November 13th, 2023

Hamburg, Germany

In an era of increasing reliance on technology, geospatial data plays a crucial role in shaping novel systems that drive decision-making, improve services, and drive innovation in fields ranging from social media and shopping to healthcare and transportation. In particular, the adoption of machine learning and deep learning techniques has heightened the demand for big geospatial data as well as magnified its transformative potential. Nevertheless, the availability and accessibility of this data, coupled with the security considerations surrounding the models that utilize it, have given rise to pressing ethical concerns that warrant our immediate attention. Striking a delicate balance between maximizing data utility and safeguarding individual privacy has become an imperative challenge. The processing of personal data poses inherent risks, including the potential infringement upon privacy rights and the potential for abuse or manipulation. As a result, profound ethical questions emerge, underscoring the interplay between utility and privacy. This workshop aims to bring together researchers and practitioners from diverse fields to delve into the multifaceted dimensions of geospatial data, unravel its potential implications and identify innovative solutions for enabling smart and safe societies.

We invite submissions covering a wide range of topics related to geospatial data-driven smart systems, including but not limited to:

Important Dates

Paper submission: September 22, 2023 (11:59PM (PDT))  (Updated)

Notification of acceptance: October 9, 2023 (Updated)

Camera ready: October 20, 2023

Workshop date: November 13, 2023

Submission Guidelines

We invite papers discussing novel research and ideas without substantial overlap with papers that have been published or that are simultaneously submitted to a journal or a conference with proceedings. Contributions can be submitted in two types:

Submissions must be in PDF format and single-blind (include author names and affiliations). Papers should be prepared according to the ACM template. Paper submissions should be made through the EasyChair system:

All submissions will be peer-reviewed and accepted papers will be published in the ACM Digital Library.

One author per accepted contribution will be required to register for the workshop and the ACM SIGSPATIAL conference, as well as attend the workshop to present the work. Otherwise, the accepted submission will not appear in the ACM Digital Library.
