Dataveillance, a method of surveillance that collects and analyzes massive amounts of data about individuals, poses a threat to information privacy because it allows companies to uncover intimate personal information that individuals never consented to disclose. No comprehensive legal framework currently exists to regulate dataveillance. A potential remedy lies in the common law torts designed to protect privacy. However, the most applicable of these privacy torts, the tort of intrusion upon seclusion, faces several doctrinal hurdles in regulating dataveillance because courts and commentators consider the initial collection of data to be the only potential privacy intrusion from dataveillance. This Note proposes that the tort of intrusion upon seclusion could be updated to effectively regulate dataveillance if courts recognize that dataveillance’s observation of new personal information constitutes its own privacy intrusion, distinct from the intrusion at the data collection stage. This doctrinal shift would overcome the doctrinal barriers to applying the intrusion upon seclusion tort to dataveillance.
