trying to reform Labour's image. <br>'The populist view has consistently been that only criminals, or those with something to hide, would contest an increase in the use of cameras,' the report argued. <br>The Information Commissioner's Office has said that the Home Office spent 78 per cent of its crime prevention budget on installing CCTV during the 1990s. <br>More cameras were installed ahead of the London 2012 Olympic Games, just weeks after the Queen's Diamond Jubilee which also required heavy security.  <br>The Metropolitan Police said in 2018 that it owns only 3,000 cameras on the sides of buildings, saying that Transport for London is responsible for more CCTV than them.<br>However, the Met announced in January that they would begin the operational use of live facial recognition (LFR) cameras in London. <br>First used in the capital at the Notting Hill carnival in 2016, the cameras will alert police when they spot anyone on 'wanted' lists. <br>      A CCTV camera in London - where police are experimenting with the use of facial recognition technology which critics say is a 'China-style surveillance tool'<br>The campaign group Big Brother Watch said last month that the use of live facial recognition was 'one of the most serious threats to civil liberties of recent years'. <br>'This China-style mass surveillance tool risks turning CCTV cameras into biometric checkpoints and citizens into walking ID cards,' they said.  <br>London transport bosses first experimented with CCTV while building the Victoria Line in the 1960s. From the 1970s onwards, it became a convenient way to phase out train guards on the Underground because drivers could monitor what was happening on CCTV. <br>The Tube network now has 13,000 cameras of its own, not including 700 on the Docklands Light Railway and 600 on the London Overground. London's thousands of buses have also been fitted with their own surveillance systems since the 1980s.    <br>Today, much of London's suite of surveillance cameras is operated by private owners in their households or cars. <br>CCTV manufacturers can self-certify that their equipment is safe from cyber attack and companies offer home surveillance systems for less than £1,000. <br>UK regulations say that data protection laws do not apply if the cameras cover only a person's private property, including their garden. <br>A 2015 study found that privately owned CCTV cameras may outnumber public ones by as much as 70 to 1 across the UK.    <br>Comparitech says it is not fully clear how many privately-owned systems are included in the estimate of 627,727 surveillance cameras across London.  <br>        A map of some of China's most-monitored cities, although figures show Beijing has fewer CCTV cameras per head than London

Frequently asked quantum questions (FAQQ) is a wikimedia website towards answering, in a well-referenced fashion, common statements, assertions, and misconceptions about how quantum computing will effect Bitcoin along with the rest of the blockchain space.

It's put together by contributing members from the Quantum Resistant Ledger.

Overview

Assertions

  1. Quantum Computing is Coming
  2. It's going to affect Bitcoin

Misconceptions

  1. Bitcoin's developers have already planned for this.
  2. Bitcoin will just hard/softfork
  3. If they can break SHA_256, we’ll upgrade to SHA_384
  4. But if you don’t reuse addresses, you’re safe because BTC only exposes the hash of your public key if you have never transferred BTC from that address
  5. Quantum computing is a long ways away, there's no need to bother
  6. If ECDSA will be broken, banks and the whole internet is broken. Blockchain is the least we’ll need to worry about then.
