No fingerprints! Fujitsu lets phone use "Palmprint Scan"

[Guide] The Palmprint scan does not require a scanning device such as the size of the palm, but an "empty scan". Tencent Digital Message (compiling: Lotus) When fingerprint scans are becoming increasingly popular in smartphones, Fujitsu is moving upstream, trying to develop a "palmprint scanning" technique for mobile phones that sounds incredible. As the leader of the trend, Apple pioneered the TouchID biometric technology, with advanced sensors and uniqueness (one sensor can only be paired with a A7 processor) to achieve superior mobile security applications, and other handset makers have followed suit. But when it comes to "palmprint scanning" technology, it seems that we have only seen it in spy movies, not in the consumer electronics world. In fact, palmprint recognition has something in common with fingerprint recognition. Human palm prints are as unique as fingerprints and do not have repeatability, but the procedure for running the equations is only half the fingerprint. The other part is about the venous point where the infrared Rays match the information before the scan. One of the key techniques is that the blood needs to flow around the palm to make the match, and obviously if the palm is separated from the limb, it cannot be identified. In terms of accuracy, the official test data of Fujitsu is 0.0008% false positive rate and 0.01% of the denial of access rate, the overall recognition level is very high. While the principle of palmprint recognition sounds "sci-fi," Fujitsu has applied it to real-world products, such as its laptops lifebook e741/c and Celsius H730. These two laptops have been put into use in Japanese banking institutions to improve information security. Now, Fujitsu is eyeing the smartphone sector, competing with Apple and other manufacturers. Perhaps mastering the application on the phone sounds absurd, but it doesn't need a scanning device like the size of a palm. Using infrared scanning mechanism, can let the user realize "the blank scan", so the scanner volume is not a problem. In addition, Fujitsu has been working to reduce the size of the scanner, the latest version applied to the Lifebook e741/c only for the stamp size. Of course, with the smartphone's big screen and screen-taking ratio rising today, the front of the handset apparently has no room to place the stamp size scanner, installed on the back of the phone to affect the use of the experience, so Fujitsu still needs to work harder to design it more compact.
