‘Conditioning an entire society’: the rise of biometric data technology

The use of our bodies to unlock access to services raises concerns about the trade-off between convenience and privacy

In a school canteen in Gateshead, cameras scan the faces of children, taking payment automatically after identifying them with facial recognition. More than 200 miles away in North London, staff at a care home recently took part in a trial that used facial data to verify their Covid-19 vaccine status. And in convenience stores around the country, staff are alerted to potential shoplifters by a smart CCTV system that taps into a database of individuals deemed suspect.

In each case, biometric data has been harnessed to try to save time and money. But the growing use of our bodies to unlock areas of the public and private sphere has raised questions about everything from privacy to data security and racial bias.
