Biometric Identification - Be your key

In the world of tomorrow, the key to your identity could quite literally be in the palm of your hand. With personal authentication becoming an essential requirement for a wide variety of purposes, such as mobile electronics, many systems now rely on biometric features to identify authorized users.

Osram Opto Semiconductors is helping to ensure these systems reach the highest level of reliability and security, to make sure the most important things in your life are as safe as they can be.

Biometric identification makes use of unique human characteristics, including facial features, the pattern of the iris, or the network of veins in the palm. The technology offers a safe and convenient alternative to managing complex passwords.

Osram Opto Semiconductors supplies special infrared LEDs for biometric recognition systems. These LEDs are used to illuminate the target area, enabling the systems to achieve high quality images, and ensuring reliable identification.

识别新机遇

手机和平板电脑越来越多地用于网上银行和网上购物等敏感应用。生物识别技术保护功能强大而又具有针对性,可有效防止他人妄用,因此在移动设备上搭载这一技术用于解锁成为最新趋势。

由于指纹会在生命过程中发生变化或者会受到外部影响,指纹扫描在一定程度上无法确保其正确性。因此,许多制造商正在考虑使用虹膜扫描作为新的生物识别解锁方法。红外光将照射眼睛,同时设备上的摄像头将拍摄虹膜画面,以便识别其特征。每个人的虹膜特征都有其唯一性。然后,扫描结果将与储存的虹膜图进行比较。虹膜扫描识别方法不仅快速,而且安全可靠,错误率低于 1%。
