Combating counterfeits with light: focus on Visualant
A light-based authentication technology developed by US company Visualant is on the brink of becoming a commercial platform, according to the firm’s founder and chief executive Ron Erickson.
The system – known as ChromaID – consists of software and a scanner that employs a technology called spectral pattern matching (SPM). Using this approach, structured light is directed onto a surface material – or through a liquid or gas – creating and capturing a unique marker that is invisible to the human eye, according to Erickson (pictured).
