(名詞) 互相監視 (surveillance)。亦寫成 co-veillance

The use of technology to support a wide array of social, economic and political interactions is generating an increasing amount of information about who, what and where we are. Through self-documentation (sousveillance), state sponsored surveillance, and documentation of interaction with others (coveillance) a vast store of information — varied in content and form — about daily life is spread across private and public data systems where it is subject to various forms of processing.
—"Info 290. Surveillance, Sousveillance, Coveillance, and Dataveillance," UC Berkeley School of Information, June 24, 2013

In this version of surveillance —a transparent coveillance where everyone sees each other — a sense of entitlement can emerge: Every person has a human right to access, and benefit from, the data about themselves.
