SmartWater is a traceable liquid and forensic asset marking system (taggant) that is applied to items of value to identify thieves and deter theft. The liquid leaves a long-lasting and unique identifier, whose presence is invisible except under an ultraviolet black light.SmartWater, the forensic technology company, was started in the early 1990s by Phil Cleary,[1] a British police officer who served approximately ten years working in various specialist departments before leaving the force in his 30s to start his own security company. His brother Mike Cleary, a Chartered Chemist and a Fellow of the Royal Society of Chemistry, created SmartWater.[2][3] Mike was responsible for the development of the technology, whereas Phil created the deterrence and business strategies.In 1996, SmartWater gained a national profile when the Clearys won the Prince of Wales Award for Innovation for the 'product with most commercial potential' on BBC's Tomorrow's World.[4] [Wikipedia]
