APPS 2022 is the 4th International Workshop on Adaptive and Personalized Privacy and Security which will be held both virtually and physically from Barcelona, Spain in conjunction with ACM UMAP 2022 - User Modelling, Adaptation and Personalization, July 07, 2022.

APPS 2022 aims to bring together researchers and practitioners working on diverse topics related to understanding and improving the usability of privacy and security software and systems, by applying user modeling, adaptation and personalization principles.

Our special focus in 2022 will be challenges and opportunities related to the security and privacy of remote activities (e.g., remote work environments, distance learning).

The workshop will address the following objectives:

• increase our understanding and knowledge on supporting usable privacy and security interaction design through novel user modeling mechanisms and adaptive user interfaces;
• discuss methods and techniques for understanding user attitudes and perceptions towards privacy and security issues in various application areas;
• identify human-centered models for the design, development and evaluation of adaptive and personalized privacy and security systems;
• discuss methods for evaluating the impact and added value of adaptation and personalization in privacy and security systems.
