The technology, called Sigard, monitors movements and speech to detect signs of threatening behavior.

Its designers claim the system can anticipate anti-social behaviour and violence by analysing the information picked up its sensors.

They say alerts are then sent to police, nightclub bouncers or shop security staff, which allow them to nip trouble in the bud before arguments spiral into violence.

The devices are designed to distinguish between distress calls, threatening behaviour and general shouting.

The system, produced by Sound Intelligence, is being used in Dutch prisons, city centres and Amsterdam’s Central Rail Station.

Coventry City Council is funding a pilot project which has for six months and has installed seven devices in the nightlife area on the High Street.

Dylan Sharpe, from Big Brother Watch, said: “There can be no justification for giving councils or the police the capability to listen in on private conversations.

“There is enormous potential for abuse, or a misheard word, causing unnecessary harm with this sort of intrusive and overbearing surveillance.”

A CV1 spokesman said: “We had the system for six months. It is no longer in use.”

No one from the organisation was available to comment on whether the trial was a success.

The new Coalition Government has announced a review of the use of CCTV with a pledge to tilt the balance away from snooping by the authorities to defend civil liberties.

Careful your cell phone may be eavesdropping. Thanks to recent developments in “spy phone” software, a do-it-yourself spook can now wirelessly transfer a wiretapping program to any mobile phone. The programs are inexpensive, and the transfer requires no special skill. The would-be spy needs to get his hands on your phone to press keys authorizing the download, but it takes just a few minutes—about the time needed to download a ringtone.

This new generation of -user-friendly spy-phone software has become widely available in the last year—and it confers stunning powers. The latest programs can silently turn on handset microphones even when no call is being made, allowing a spy to listen to voices in a room halfway around the world. Targets are none the wiser: neither call logs nor phone bills show records of the secretly transmitted data.

More than 200 companies sell spy-phone software online, at prices as low as $50 (a few programs cost more than $300). Vendors are loath to release sales figures. But some experts—private investigators and consultants in counter-wiretapping, computer-security software and telecommunications market research—claim that a surprising number of people carry a mobile that has been compromised, usually by a spouse, lover, parent or co-worker. Many employees, experts say, hope to discover a supervisor’s dishonest dealings and tip off the top boss anonymously. Max Maiellaro, head of Agata Christie Investigation, a private-investigation firm in Milan, estimates that 3 percent of mobiles in France and Germany are tapped, and about 5 percent or so in Greece, Italy, Romania and Spain. James Atkinson, a spy-phone expert at Granite Island Group, a security consultancy in Gloucester, Massachusetts, puts the number of tapped phones in the U.S. at 3 percent. (These approximations do not take into account government wiretapping.) Even if these numbers are inflated, clearly many otherwise law-abiding citizens are willing to break wiretapping laws.

Spyware thrives on iPhones, BlackBerrys and other smart phones because they have ample processing power. In the United States, the spread of GSM networks, which are more vulnerable than older technologies, has also enlarged the pool of potential victims. Spyware being developed for law-enforcement agencies will accompany a text message and automatically install itself in the victim’s phone when the message is opened, according to an Italian developer who declined to be identified. One worry is that the software will find its way into the hands of criminals.

The current predicament is partly the result of decisions by Apple, Microsoft and Research In Motion (producer of the BlackBerry) to open their phones to outside application-software developers, which created the opening for spyware. Antivirus and security programs developed for computers require too much processing power, even for smart phones. Although security programs are available for phones, by and large users haven’t given the threat much thought. If the spying keeps spreading, that may change soon.

The British government said Monday it wants communications companies to keep records of every phone call, email and Web-site visit made in the country. But it has decided not to set up a national database of the information, a proposal civil liberties group had been condemned as a “Big Brother”-style invasion of privacy.

The government said in October it was considering a central database of phone and Internet traffic as part of a high-tech strategy to fight terrorism and crime. But Home Secretary Jacqui Smith said Monday the plan had been dropped.

A document outlining the department’s proposals said the government “recognizes the privacy implications” of a database and “does not propose to pursue this approach.”

Instead, the government said it was backing a “middle way” that would see service providers store and organize information on every individual’s phone and Internet traffic so that it could be accessed by police and other authorities upon request.

The Home Office estimated introducing the new system would cost up to £2 billion ($3 billion).

Under current rules, British Internet service providers are already required to store records of Web and e-mail traffic for a year. The new proposals would also require them to retain details of communications that originated in other countries but passed across British networks — for example if someone in Britain accessed a U.S.-based e-mail account.

The government said providers wouldn’t store the content of calls, e-mails or Internet use. They would retain details of times, dates, phone numbers, e-mail addresses and Web site URLs.

Ms. Smith said officials had to strike “a delicate balance between privacy and security,” but insisted police and intelligence agencies needed more tools to fight crime and terrorism in an increasingly complex online world.

“Advances in communications mean that there are ever more sophisticated ways to communicate and we need to ensure that we keep up with the technology being used by those who would seek to do us harm,” Ms. Smith said.

The proposals are still a long way from becoming law. The government is seeking public comment until July, and widespread opposition is expected.

The government said there would be strict safeguards on who could access the information, but critics say existing surveillance powers have been abused by local authorities investigating relatively trivial offenses such as littering. That led the government in December to say it would clamp down on abuses of surveillance laws.

Trust in the government also has been hit by a series of lost-data incidents. In November, a government department lost a disk that contained the names, addresses and bank details of 25 million people.
