Apple's Heartbeat Unlock: Your Pulse is the New Key to Your Devices

A groundbreaking Apple patent reveals a futuristic method to unlock devices using your unique heartbeat, setting a new standard for security and convenience.

ECG Tracks Unique Heartbeat

In the future, Apple plans to make it so that your Apple Watch or future iPhone may detect your unique heartbeat and unlock your smartphone with the simple wave of a finger.

Through its electrocardiogram (ECG) app, the Apple Watch is able to track each individual's heartbeat. Apple details a method for user identification using their unique heart rate and other physiological parameters in a patent that was just issued.

Heart Patterns Boost Security

By utilizing this technology, all of your devices can be unlocked just by continuing to wear your Apple Watch. You may speed up the identification process and boost security by using your heart patterns as a verification rather than a password or fingerprint scan.

Take Apple Watches as an example; at the moment, you can't use them to unlock Macs without first entering a passcode. You might bypass the need to input a password or passcode by simply strapping your Apple Watch to your chest and collecting an electrocardiogram reading. You can use your watch as an authentication token to gain access to other devices as long as you keep it on your wrist.

AppleInsider elaborates that two points of contact are required for an electrocardiogram (ECG) readout. The Apple device's digital crown and rear of the device house its sensors. A digital crown touch initiates a circuit that permits the measurement of the heart when the ECG app is launched.

Heart-Measuring Gadget in iPhone

By just holding the iPhone properly, it would be able to authenticate using heart rate, according to Apple's patent. A heart-measuring gadget would be built into the entire iPhone casing.

The patent goes on to mention that electrocardiogram data can be used to determine the user's "mood." Using heart rate data collected while exercising as an example, Apple suggests listening to music at the perfect tempo to complement the exercise.

For instance, during a user's workout, the app may stream a faster-paced song, and during their cooldown, it could automatically play a slower-paced song.

All four of these people—Andrew B. Hodge, Gloria Lin, and Taido L. Makajima—were named in the patent. One of Lin's many patents is for user identification using data other than biometrics.
