AN OXFORD professor has claimed that we are allowing more and more of our personal data to be used - and are being spied on by DOORBELLS. 

Professor Carissa Veliz  has warned that our cars, TV's, computers and phones are all tracking our data with our permission. 

She has explained that the data collection starts from the moment that you wake up, letting smartphone manufacturers, app developers and your mobile phone company know where you are and who you're with. 

The professor at the Institute for Ethics in Artificial Intelligence at the University of Oxford believes that people are "unwittingly" giving away personal information every day. 

Cars are able to log the locations you visit, the speed that the vehicle is driven at, the music played and even the weight of the driver on the seat. 

Intimate medical data can even be donated by the NHS to commercial organisations without consent, she explains.
