The furore around the Chinese government’s Green Dam software has raised the issue of the way modern technology is used to monitor our daily lives. Here, we list seven of the technologies that can be used to keep track of your movements.
CCTV
Closed-circuit television cameras were first used in Germany in 1942 to remotely monitor the launch of V2 rockets. Since then, CCTVs have become one of the most contentious pieces of technology in public use. The government and law enforcement agencies claim the use of video monitoring technology can help reduce crime and improve public safety; critics argue that the cameras serve only to displace crime to unmonitored areas, and do not act as a deterrent. With more than four million CCTV units in the UK, the network of cameras captures the average person around 25 times a day.
RFID tags
Radio frequency identification chips are already widely used in supermarkets and shops for the purpose of stock control, but some people fear their use could be widened to monitor the habits and behaviour of ordinary citizens. At the moment, these tags, which are little bigger than a grain of sand, are embedded into pints of milk and library books. When paired with an RFID reader, the tags can help to provide detailed information about items, such as their location, or how many there are. Although most people are happy for RFID tags to be used in stores to monitor stock levels, they’re less happy about the idea of the chips still sending out a signal once they leave the shop. On a benign level, such tracking capabilities would mean a store would know that people in Hertfordshire prefer blue cashmere jumpers, while those in Aberdeen favour the brown versions. But on a more sinister level, it could also enable them to glean an unprecedented insight into our personal lives, and target their brands to us accordingly. To those people who fear a “surveillance culture”, the ability to tag and track everything from our food to our clothes would be the next step on an already slippery slope.
