Privacy by obfuscation with personal data management architectures: possibilities and constraints

In this position paper, we discuss legal and technical aspects of protecting privacy using Personal Data Management Architectures (PDMAs), which include, but are not limited to Personal Data Stores and Personal Information Management Services. We argue that providing false information on occasion is a common strategy online and offline for people to protect their privacy and determine their representation in the world, and we discuss some empirical findings to that effect. We describe a potential, and technically-feasible, ecosystem of digital practices and technologies to facilitate this practice, and consider what legal frameworks would be required to support it
