The European Commission is reportedly considering sweeping reforms to facial recognition regulation to protect citizens from public surveillance, said the Financial Times on Thursday.
Quoting an EU official, the newspaper said new legislation could limit "the indiscriminate use of facial recognition technology."
European citizens would be given powers to "know when [facial recognition] data is used."
The Commission didn't comment directly on the plans, but a commission spokesman pointed to a high-level expert group that was set up in June to consider the need for new regulation when it comes to tracking and profiling, including facial recognition.
Discussions around regulating facial recognition technology follow the introduction of a number of public trials around Europe, some of which have been conducted without users knowing they were taking place.
The UK's data protection watchdog is currently investigating the use of the technology to monitor crowds around London's King Cross.
