Plans to fit all taxis operating in the city of Oxford with audio recording devices have been branded a “staggering invasion of privacy” prompting calls for the Information Commissioner’s Office (ICO) to investigate how widespread the use of microphones on public transport has become.
Taxi drivers in the university town have been told that they need to install the £460 devices by 2015 or face having their licenses revoked. The microphones, accompanied by CCTV cameras, will activate once the ignition in the car is turned on and will remain recording for 30 minutes after the engine is turned off.
The council says the recording equipment is necessary to protect drivers and passengers as well as deal with any disputes over fares. Recorded information would only be accessible to the police or council officials.
But privacy campaigners say the plans represent a significant “ramping up” of surveillance culture in Britain and may well be in breach of Government guidelines.
