This document discusses privacy concerns arising from clashes between new technological capabilities and societal expectations of privacy. It summarizes issues such as statistical databases allowing individual inference, data aggregation uniquely identifying individuals, monitoring technologies for location, behavior and communications, and challenges around encryption, data repurposing, digital watermarking, implanted RFIDs, genome sequencing, and more. The conclusion notes that many new technologies violate privacy expectations, and that laws have lagged in addressing these issues created by advancing technologies.
