Patent Describes Future Apple Watch May Add Bioauthentication Feature

Nowadays, biometric technology has been widely used for mobile device security. Devices such as iPad and iPad either have fingerprint recognition or facial recognition. However, Apple Watches are the exceptions: when you access the wearable, you must enter the passcode that you have set up already...

Recently, the US Patent and Trademark Office approved Apple's patent for "Wearable Electronic Device Having a Light Field Camera Usable to Perform Bioauthentication from a Dorsal Side of a Forearm Near a Wrist." As the title suggests, Apple is considering using a light field camera on the back of the Apple Watch, which actually consists of multiple camera sensors and light emitters. Sensors can work together to capture enough data to form a complete scene image.

In this way, the camera and sensor component group will capture images when the Apple Watch is in contact with the wrist to capture elements under the skin, thereby detecting biometric information for the wearer including hair follicle openings, blood vessel patterns, veins, arteries, tendons, connective tissue, skin pigmentation, pores, and bone shapes. Then use one or more of these elements for authentication.

This patent has some outlook because it could potentially improve the security of Apple Watch in its current state, making it as safe as the Face ID on the iPhone. Though it should be noted that Apple routinely submits a large number of patent applications to the US Patent and Trademark Office, it does not guarantee that these ideas will enter future Apple products and services. They typically shows Apple's interest in this aspect.
