Electronic surveillance and collection of personal data are pervasive" in British society and threaten to undermine democracy, peers [in the House of Lords] have warned. CCTV cameras and the DNA database were two examples of threats to privacy, the Lords constitution committee said. It called for compensation for people subject to illegal surveillance. Civil liberties campaigners have warned about the risks of a "surveillance society" in which the state acquires ever-greater powers to track people's movements and retain personal data. In its report, the Lords constitution committee said growth in surveillance by both the state and the private sector risked threatening people's right to privacy, which it said was "an essential pre-requisite to the exercise of individual freedom". People were often unaware of the scale of personal information held and exchanged by public bodies, it said. "There can be no justification for this gradual but incessant creep towards every detail about us being recorded and pored over by the state," committee chairman and Tory peer Lord Goodlad said. "The huge rise in surveillance and data collection by the state and other organisations risks undermining the long-standing tradition of privacy and individual freedom which are vital for democracy," Lord Goodlad added. Human rights campaigners Liberty welcomed the report.
