Here's the paper's abstract: 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. It has a wide range of applications, including detecting forged currency and tickets, authenticating passports, and halting counterfeit goods. Document identification could also be applied maliciously to de-anonymize printed surveys and to compromise the secrecy of paper ballots.

The Federal Bureau of Investigation is expanding beyond its traditional fingerprint-focused collection practices to develop a new biometrics system that will include DNA records, 3-D facial imaging, palm prints and voice scans, blended to create what's known as "multi-modal biometrics." Slideshow: The changing face of biometrics How the Defense Department might institutionalize war-time biometrics "The FBI today is announcing a rapid DNA initiative," said Louis Grever, executive assistant director of the FBI's science and technology branch, during his keynote presentation at the Biometric Consortium Conference in Tampa. The FBI plans to begin migrating from its IAFIS database, established in the mid-1990s to hold its vast fingerprint data, to a next-generation system that's expected to be in prototype early next year. This multi-modal NGI biometrics database system will hold DNA records and more.

"Yesterday, a "Your iPhone's been hacked because it's really insecure! Please visit doiop.com/iHacked and secure your phone right now!" message popped up on the screens of a large number of automatically exploited Dutch iPhone users, demanding $4.95 for instructions on how to secure their iPhones and remove the message from appearing at startup. Through a combination of port scanning and OS fingerprinting of T-Mobile's 3G IP range, a Dutch teenager has for the first time automatically exploited a known security vulnerability introduced on jailbroken iPhones - the SSH daemon which unless modified remains running with default users root and mobile, using the same password on each and every device."
