'Uncrackable' Document and Product Security?
Curunculus writes "The Engineer reports that a unique 'fingerprint' formed by microscopic surface imperfections on almost all paper documents, plastic cards and product packaging could be used as a cheaper method to combat fraud.
One of the developers, Professor Cowburn commented: "The beauty of this system is that there is no need to modify the item being protected in any way with tags, chips or inks; it's as if documents and packaging have their own unique DNA. This makes protection covert, low-cost, simple to integrate into the manufacturing process and immune to attacks against the security feature itself."
This system is now being commercialised via Ingenia Technology, a spin off company."
