A secret database of citizens' personal lives and habits isn't explicitly spelled out in the UK's latest surveillance law. No, instead, it's described as a set of "request filters."
The term is buried in the draft Investigatory Powers Bill (IPB), which was introduced to Parliament on Wednesday. Turn to page 254 of the 299-page document [PDF], and you'll find it under "Clause 51: Filtering arrangements for obtaining data."
Such arrangements, the proposed law states, will be implemented by the Secretary of State, and no mention is made of any judicial oversight.
The request filters are ways in which the authorities can, without a court warrant, search for and organize information on citizens from their "internet connection records," which are held for 12 months, presumably stored by the ISPs
