The Information Revolution has thoroughly transformed society. One of the major implications of this technological shift has been a massive increase in the collection, sharing, and analysis of personal data. The goal of this workshop is to discuss the privacy problems that result as well as their solutions. This will be the 18th occurrence of this annual forum, which is held in conjunction with the ACM CCS conference. The workshop seeks submissions from academia, government, and industry 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:

• attacks on data privacy
