The need for privacy-aware policies, regulations, and techniques has been widely recognized. This workshop discusses the problems of privacy in the global interconnected societies and possible solutions. The 2022 Workshop, held in conjunction with the ACM CCS conference, is the twenty-first in a yearly forum for papers on all the different aspects of privacy in today's electronic society.

The workshop seeks submissions from academia, industry, and government presenting novel research on all theoretical and practical aspects of electronic privacy, as well as experimental studies of fielded systems. We encourage submissions from other communities such as law and business that present these communities' perspectives on technological issues. Topics of interest include, but are not limited to:

- access and query privacy

SUBMISSION INSTRUCTIONS
------------------------
Submitted papers must not substantially overlap papers that have been published or that are simultaneously submitted to a journal or a conference with proceedings. Submissions should be no more than 12 pages in the ACM double-column format, excluding the bibliography and well-marked appendix. Committee members are not required to read the appendices, and so the paper should be intelligible without them. Submissions should not be anonymized. The workshop will also consider short submissions of up to 4 pages for results that are preliminary or that simply require few pages to describe. Authors of regular submitted papers will indicate at the time of submission whether they would like their paper to also be considered for publication as a short paper (4 proceedings pages).

Submissions are to be made to the submission website at EasyChair. Only PDF files will be accepted. Submissions not meeting these guidelines risk rejection without consideration of their merits. Papers must be received by the deadline of July 16, 2022 (11:59 PM American Samoa time) to be considered. Notification of acceptance or rejection will be sent to authors by August 31, 2022.

Authors of accepted papers must guarantee that their paper will be presented at the workshop.
