"Bodyprint compensates for the low input resolution with an increased false rejection rate, but does not compromise on authentication precision," the team wrote. "In our evaluation with 12 participants, Bodyprint classified body parts with 99.98 percent accuracy and identifies users with 99.52 percent accuracy, with a false rejection rate of 26.82 percent accuracy to prevent false positives."The team tested the system against a range of prints. This includes the aforementioned ear print; the print of the user's knuckles and fingers when they press a fist to the screen; the shape created when the user curls their fingers and presses their intermediate phalanges to the screen; the shape of the user's palm on the screen; and the shape made by the users fingers as they grip the phone around the back.

These prints were obtained by taking and analysing images of the touch patterns on the screen, rather than two-dimensional location caring for your demon cat iphone case mapping, which is how mobile devices track and process gestures, The results were precise: "Scanning users' ears for identification, Bodyprint achieves 99.8 percent authentication precision with a false-rejection rate of 1 out of 13, thereby bringing reliable biometric user authentication to a vast number of commodity devices."In a video demonstrating the technology, Bioprint can also be keyed to multiple users on a single device, The use case shown was the phone requiring two users' permission to access a document, It's also possible that the technology could improve in the future..

"In the case that future touchscreens support higher input resolutions, up to a point where they may detect the fine structure of fingerprints, Bodyprint will readily incorporate the higher level of detail of sensor data, which will not only extend our approach to further body parts, but likely reduce false rejection rates at the same high levels of authentication precision," the team said. The next step in the development of Bodyprint is the improvement of the recognition algorithms, before testing on a wider scale.

Apple in October said it wouldn't break out Apple Watch sales, but many hoped the company would give some details about first-weekend sales as it has tended to do for iPhones, The smartwatch, which hit the market Friday, ranges in price from $349 for the aluminum sport version to $17,000 for the 18-karat-gold model, The device requires an iPhone 5 or newer to run basic apps and receive notifications and comes in 38 different combinations, Preoders for the device started caring for your demon cat iphone case April 10, and for now, Apple's only accepting orders online..

Cook tends to use phrases like "amazing," "staggering" and unprecedented" when describing new product launches. But when it came to the Apple Watch on the company's fiscal second-quarter earnings call with analysts on Monday, he sounded a little more muted. Cook largely danced around questions about the company's first smartwatch, only saying customer response has been "overwhelmingly positive," he's "really happy" with where Apple is currently, and Apple's moving as quickly as it can to meet demand.
