PETS 2019 19th Privacy Enhancing Technologies Symposium Stockholm, Sweden July 16-20, 2019 https://petsymposium.org/ Submission deadlines: August 31, 2018; November 30, 2018; February 28, 2019 The annual Privacy Enhancing Technologies Symposium (PETS) brings together privacy experts from around the world to present and discuss recent advances and new perspectives on research in privacy technologies. Papers undergo a journal-style reviewing process and accepted papers are published in Proceedings on Privacy Enhancing Technologies (PoPETs), a scholarly, open access journal. Submitted papers should present novel practical and/or theoretical research into the design, analysis, experimentation, or fielding of privacy-enhancing technologies. While PETS/PoPETs has traditionally been home to research on anonymity systems and privacy-oriented cryptography, we strongly encourage submissions on a number of both well-established and emerging privacy-related topics, for which examples are provided below. PoPETs also solicits submissions for Systematization of Knowledge (SoK) papers. These are papers that critically review, evaluate, and contextualize work in areas for which a body of prior literature exists, and whose contribution lies in systematizing the existing knowledge in that area. Suggested topics include but are not restricted to: Behavioural targeting Blockchain technologies applied to privacy Building and deploying privacy-enhancing systems Crowdsourcing for privacy Cryptographic tools for privacy Data protection technologies Differential privacy Economics and game-theoretical approaches to privacy Empirical studies of privacy in real-world systems Forensics and privacy Human factors, usability and user-centered design for PETs Information leakage, data correlation and generic attacks to privacy Interdisciplinary research connecting privacy to economics, law, ethnography, psychology, medicine, biotechnology, human rights Location and mobility privacy Machine learning and privacy Measuring and quantifying privacy Mobile devices and privacy Obfuscation-based privacy Policy languages and tools for privacy Privacy in cloud and big-data applications Privacy in social networks Privacy-enhanced access control, authentication, and identity management Profiling and data mining Reliability, robustness, and abuse prevention in privacy systems Surveillance Systems for anonymous communications and censorship resistance Traffic analysis Transparency enhancing tools Web privacy
