ICO outlines legal conditions for police use of facial recognition

The UK Information Commissioner’s Office published new guidance outlining when law enforcement may legally deploy live facial recognition technology under data protection laws. 

The ICO demands law enforcement usage meet a relatively high bar: the use of such technology must be strictly necessary and specific in nature, proven to be effective under the particular circumstances, and only used when no less intrusive alternatives exist. 

Law enforcement agencies are required to conduct detailed data protection impact assessments and document how the technology achieves their stated objectives. 

The guidelines also discuss how the use of images in watchlists, stating that they must meet the same legal standards.

This announcement reflects growing concern over the use of real-time surveillance technologies in public spaces. The ICO’s position signals an intent to set firmer boundaries for authorities, encouraging agencies to reassess how they deploy advanced technology tools.
