Apple always strived to make its devices as safe from prying eyes as possible. It was one of the first companies to introduce fingerprint scanning, implementing it in iPhone 5s in 2013. The company lets Mac computers be unblocked with the help of Apple Watch.

The new generation of Apple Watch will identify its owner by their pulse

Now it has approached the question of accessory security. The Apple Watch currently requires entering a PIN code every time the device is taken off the owner’s wrist. However, Apple intends to go even further.

The company plans to identify the owner of the smartwatch by their pulse.

A new patent application by Apple describes the principle of identifying the owner with the help of the heart rate sensor built into the smartwatch. Biometric authentication is one of the most reliable security measures. Engineers consider gathering data about blood oxygen levels to create a software algorithm that compares the readings with those of the owner.
