Apple invents new Apple Watch biometric ID system using plethysmography

“Apple’s introduction of Touch ID was made by Vice President of Marketing Phil Schiller during an iPhone media event on September 10, 2013,” Jack Purcher reports for Patently Apple.

“Today, a new Biometrics related patent surfaced in Europe with a whole new approach to bringing biometric ID to the Apple Watch,” Purcher reports. “Apple invention relates to biometric identification based on Plethysmography. In examples of the present disclosure, light emitters and light sensors can be used to perform biometric identification of a user based on identifying characteristics of the user’s vasculature. For example, light information can be obtained at one or more light sensors, and the information can be compared to stored information associated with a user identity. Based on the comparison, the user of the device can be identified as having the user identity.”

MacDailyNews Take: That’s a bit sleeker than requiring users to enter a four-digit code to identify themselves to Apple Watch (akin to the jump on iPhone from unlocking codes to Touch ID).

    1. Because if I put my iPhone on my desk and walk about the house, to the kitchen, to the washroom to the basement, etc, suddenly you will find the watch is not authenticated.

  1. To quote Hillary, “At this point what difference does it make?” Few people are buying the Watch according to the WSJ.

    Get back to building decent computers Apple.

  2. Another common type of plethysmograph is the penile plethysmograph. This device is used to measure changes in blood flow in the penis. Although some researchers use this device to assess sexual arousal and sexual orientation, the data are usually not admissible in court cases in the United States. An approximate female equivalent to penile plethysmography is vaginal photoplethysmography, which optically measures blood flow in the vagina.

  3. But you can already unlock your apple watch using your iPhone’s Touch ID. I’m not saying we don’t need an advancement for the Watch, just that MDN’s take seems to have forgotten this was possible. I do this 90% of the time.

  4. If Apple can get plethysmography working reliably, that means Watch can become a blood pressure monitor, as well as heart rate and blood oxygen monitor, connected wirelessly to anywhere that you need to keep an eye on the situation. All those doo-dads on stands whose job it is to hover around hospital beds blinking and beeping need to start contemplating their future.

  5. I’m going to bet that this ‘identification’ is iffy, at least with the current hardware. This isn’t high rez imaging. Human physiology changes with the weather. Watches don’t always sit on exactly the same spot of a person’s arm, etc.
