Laser Spots Paper Fingerprints
A low-cost laser scanning system could help in the fight against document and ID fraud, according to its developers at Imperial College London.
The Laser Surface Authentication (LSA) system scans tiny surface variations of paper, plastic, metal and ceramics to detect the material’s “fingerprint”.
If deployed, it means that a passport, for example, could be quickly scanned using the system and its laser speckles recorded and encoded in a unique serial number or onto a database before being issued.
It could then be quickly re-scanned and checked against its record when authentification is required.
The laser system, which includes a low-cost, portable scanner, is extremely accurate, according to the research team, and it also still recognised surface patterns after the materials had been abused.
Different materials were handled roughly, placed in water, burnt, scoured with an abrasive cleaning pad and covered in black marker pen, but the laser was still able to read the surface fingerprint.
Read the article. What do you think? How important is this?

And infringe on the rights of terrorists and law breaking individuals all over the world? Forget it – it’s never going to be implemented.
These undesireables have more rights than us.
Rather insignificant, if you ask me.
