This paper presents a novel technique for authenticating physical documents based on random, naturally occurring imperfections in paper texture. We introduce a new method for measuring the three-dimensional surface of a page using only a commodity scanner and without modifying the document in any way. From this physical feature, we generate a concise fingerprint that uniquely identifies the document. Our technique is secure against counterfeiting and robust to harsh handling; it can be used even before any content is printed on a page.
That statement's been debunked several times...
...mind you, most music stores won't mind if it was a famous artist...
Having worked at a music store (chain, not a mom-n-pop), I most certainly would have minded if any artist (whether I recognized the artist or not) tried to walk out without paying. If they could take the nebulous "music" without denying us the physical property (the CD) that we had to inventory, track, and account for - then yes. But since you can't (at this time in 99% or more of cases) take music from a music store without also taking the physical media, you also cannot take the music for free. No matter who you are.
