Authentication of Physical Object Using Internal Structure
Our researchers have identified a technique that reveals the unique ‘texture’ fingerprint for every single sheet of paper. It enables a digital signature of original paper documents to be created.
The Challenge
Proving the authenticity of valuable documents uses ever-more sophisticated countermeasures eg. RFID, embedded chips, specialised security papers, printed foils and holograms.
Examples of valuable documents are:
- passports
- academic certificates
- contracts
- banknotes
A unique, low cost, scalable and rapid means to prove authenticity would be a significant tool to combat counterfeiters and criminals.
The Solution
Our researchers have identified a unique ‘texture’ fingerprint for every single sheet of paper. This is achieved by analysing the translucent patterns revealed when a light shines through paper.
The fingerprint is made up from the randomised and unique arrangement of wood pulp particles in a sheet of paper as it is manufactured. Taking an image of this pattern or ‘paper fingerprint’ enables a digital signature of the document to be created.
Images can be taken using a simple light source together with a standard digital or mobile phone camera. It takes just 1.3 seconds and one snapshot to capture those internal structures and textures. This creates a digital signature. It takes a similar amount of time to take an image of the same area and authenticate the digital signature of a document.
We believe the technique will prevent counterfeiting of any paper-made physical documents.
The Opportunity
