Facewatch, the UK’s leading provider of live facial recognition technology to UK retailers, has appointed Dean Armstrong KC as its Data Protection Officer.
Armstrong is one of the UK’s most senior and widely cited barristers in data protection, cyber law and artificial intelligence.
His appointment as Data Protection Officer (DPO), which is a Statutory role under UK GDPR, brings to Facewatch a level of legal seniority rarely seen in the data protection function of a private company.
Announcing the appointment, CEO Nick Fisher said it reflects the company’s view that the responsibilities of operating live facial recognition technology at scale require oversight of the highest possible standard.
He said: “Dean is one of the most respected legal minds in the country on data protection, AI and the law that governs them. His arrival as our Data Protection Officer is a statement of intent.
“The United Kingdom is ahead of almost every comparable market in the world in the responsible commercial use of live facial recognition, and the retail sector here is leading that adoption.
“With that leadership comes a responsibility to set the highest standards of governance, transparency and accountability, not just to meet them.
“Dean’s experience, including his work advising in this exact field, means we have appointed someone who understands the technology, the legal framework, and the important wider public interest considerations.”
Fisher added: “This is the right appointment at the right time for Facewatch, for our retail subscribers, and for the workers and shoppers our system is designed to protect.”
The appointment comes at a defining moment for the technology in the UK. Britain has emerged as the most mature market in the world for the commercial deployment of live facial recognition in retail, with adoption accelerating against a backdrop of expanding use by police forces and growing public debate over the framework within which the technology operates.
Dean Armstrong KC said: “Live facial recognition raises important questions around governance, accountability and proportionality, particularly as adoption grows across both the public and private sectors.
“What matters is not simply whether organisations use these technologies, but whether they do so lawfully, transparently and with appropriate safeguards in place.
“During my long association with Facewatch, I have always been struck by the care and precision shown by them over compliance with the law both in letter but also in spirit.”
“Facewatch continues to demonstrate a serious commitment to those responsibilities, and I look forward to supporting the company as the legal and regulatory landscape in this area continues to evolve.”
Facewatch operates as a Data Controller under UK GDPR and provides live facial recognition technology to a growing number of retailers across the UK, alerting store teams instantly when individuals previously involved in criminal behaviour enter a protected store.
The company’s technology, used by more than 125 retailers operating thousands of stores across the UK, has helped deter repeat offending by up to 70% in stores while improving staff safety and morale at a time when there are 1,600 incidents of abuse and violence against shop workers, according the British Retail Consortium.
In 2025 alone, the system generated more than 500,000 real-time alerts of known offenders, with each alert representing a crime deterred or a member of shop staff sparred from abuse or worse.
Retail clients include national chains and independent retailers, including Budgens, Frasers Group, Flannels, Home Bargains, Sainsbury’s, Sports Direct, and – as retail crime increasingly spreads from more traditional targets – garden centres and charity shops.
