Relying just on a password to keep the data secure on a laptop is not a great idea, especially if it contains very sensitive information. Drive encryption, and the ability to remotely wipe your machine are both becoming popular security options. If you want a uniqie way to identify yourself at login, though, the best choice at the moment is a fingerprint reader which some laptops ship with.Fujitsu has improved upon fingerprint identification, however, and is pushing ahead with vein authentication sensors. These senors look at the palm of your hand and identify your vein pattern which is unique. The benefit of such a system is it requires no contact with the hand. The problems are various, though, with sensors being too big to deploy in a mobile device, and not being able to cope with any movement of your hand meaning lots of bad reads and an extended authentication process for the user.Those problems seem to have been solved now as Fujitsu has just unveiled its smallest and slimmest ever vein sensor, thought to be the smallest in the world. Measuring just 29 x 29 x 11mm, it is small enough to be incorporated into a laptop or other portable gadgets (external hard drives?).Fujitsu managed to slim down the sensor significantly by using a new lighting system that fits into half the space of previous models. The result is a sensor that could be an option on your next laptop.Fujitsu didn’t just stop at miniaturization, though. The other big problem was handling movement, so the new sensor was made capable of capturing multiple images at 20fps. That means it can pick the best image from a sample and get a clearer reading with a vastly improved success rate. It also means a faster authentication process for the user.Vein authentication is desirable because it relies on an invisible pattern of veins making it very secure. It also requires no contact with the user’s hand making it hygienic for high-traffic authentication, and with Fujitsu’s new sensor it is now very fast and error free too.Read more at the Fujitsu press release
