“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).
