What you see here is an 8.5×11 firearm of newspaper publisher scan by an average scanner ( with the contrast demote up ) . From shots like this one , researchers claim they can “ fingerprint ” any spell of paper .
The staring method is explained in the report Fingerprinting Blank Paper Using Commodity Scanners . Here ’s the outline :
This paper represent a novel technique for authenticate forcible documents based on random , naturally occurring imperfections in theme grain . We stick in a fresh method acting for evaluate the three - dimensional Earth’s surface of a varlet using only a commodity scanner and without modifying the written document in any way . From this physical feature article , we generate a concise fingermark that uniquely identify the document . Our proficiency is inviolable against counterfeiting and robust to harsh handling ; it can be used even before any subject is printed on a Sir Frederick Handley Page . It has a wide image of software , admit observe forged currency and tag , authenticating passport , and halting imitative goods . Document identification could also be apply maliciously to de - anonymize print surveys and to compromise the secretiveness of paper ballots .
basically , by scan a man of paper from several angle , it ’s potential to utilize shadow readings to reconstruct the paper ’s unique three-D features — what becomes the basic fingerprint . This fingermark data can then be store in something as wide-eyed as a barcode for tardy validation .
Now if we could only authenticate our digital information with such foolproof mensuration . [ Freedom to Tinkerviaboingboing ]
