JUSTICE Secretary Michael Matheson has warned that Labour and Scottish Liberal Democrats are blowing fears about facial recognition software “out of proportion”.

The minister was responding to questions in the Scottish Parliament about Police Scotland’s use of the controversial technology.

Pictures of people charged with an offence in Scotland are being uploaded to a UK-wide central database used by all police forces. It is used primarily as a way of identifying suspects caught on CCTV.

Police Scotland have confirmed that people’s pictures are “weeded” out if they are not convicted. That this was happening, seemingly without the knowledge of Government or the Scottish Police Authority, was another example of the force’s lack of accountability, said Labour legal affairs spokeswoman Elaine Murray.

Matheson said: “I think it’s important that we keep a level perspective around these matters. Trying to wrap this into armed police officers and stop and search again is just blowing it all out of proportion.

“I believe that there are areas where the Scottish Police Authority can improve the way that it is operating. The chief inspector of constabulary has already looked at that; there is an action plan in place in order to improve these areas as well.

“So, I think it is important that we recognise that although there will be issues that have to be addressed at various times on how policing is taken forward and how the SPA is operating, I think to try and just roll this all into ‘everything is just bad’ doesn’t help anyone and take any of these issues forward.”

LibDem justice spokeswoman Alison McInnes said: “Without adequate legal safeguards, there is nothing to stop the police from using this technology for mass surveillance.

“I also have real concerns that the privacy of innocent people could be compromised and they could be exposed to the risk of false identification.

Detective Chief Inspector Russell Penman of Police Scotland said: “Facial search is an intelligence tool that can be used for intelligence development purposes.

“It is not used for formal photographic identification procedures, although it does provide intelligence around the suspected identity of an individual whose image has been taken and searched.”
