Tencent Digital (Wen Xin) According to the MacRumors website, a patent application published by the U.S. Patent and Trademark Office today shows that the new generation of Apple Watch can identify users by monitoring their heart rate.
The patent applied by Apple is called "a plethysmography-based user identification system" and describes a method for determining a user's heart beat biometric identification signal using a pulse oximeter. The resulting data can be used to identify the identity of the wearer and unlock the Apple Watch in a manner similar to Touch ID on the iPhone.
MacRumors said that the new system works like the existing monitoring system by projecting light on the user's skin and measuring the light that is absorbed and reflected back to determine the amount of blood in the blood vessels. According to the patent application materials, the data collected by the two photoreceptors can be stored or compared with previously stored information to identify the user's identity.
Another Apple patent announced today uses data collected from active sensors such as accelerometers and gyroscopes to determine user activity. Some gestures, such as lifting the device from the waist to the head, trigger the recognition process.
According to the AppleInsider article, although it is unclear whether heart rate data is unique and can be used to securely identify user identities, the new system can replace Touch ID in the Apple Pay payment process, further reducing Apple Watch’s dependence on the iPhone. degree.
