Surveillance is typically envisaged as the act of a person being physically watched, their movements and behaviour monitored in a given space and time. While this type of watching undoubtedly takes place, there is also the more subtle and pervasive monitoring of people through the data they accumulate in their daily lives. Contemporary Irish society is mediated by digital technology; the daily life of the typical person creates a mass of data which can offer many telling clues as to the type of life they lead. This form of surveillance is called dataveillance (Clarke, 1988). It is unclear however exactly how much citizens know about these practices and how they negotiate with and respond to surveillance systems. This study aimed--by conducting focused interviews with Irish citizens--to explore the levels of knowledge regarding surveillance and privacy and to ascertain the importance placed on these concepts. Using Harper's (2011) typology of subject positions, a further aim was to uncover any discursive repertoires used when defining or speaking about these concepts. It was found that widely used conceptions of privacy and surveillance are inadequate to describe contemporary reality; and that forms of sociality have changed with the widespread use of information and communication technologies (ICT).
