Concept: Apple Watch 3FA Security with Biomarkers
Apple Watch does so much already. Fitness tracking is one thing it does well. What if we repurpose its high-tech sensors? What if we use the Apple Watch for extreme security?
This is where 3FA or three-factor authentication comes into the picture. It adds an extra layer of security on top of the existing two-factor authentication most of us are familiar with. You know, the code you receive via SMS or the QR code you scan with an app. With three-factor authentication, Apple Watch could check and verify one more thing.
Imagine you login to your bank account. First, you type your password. Next, you enter a separate code through an app or SMS. Finally, Apple Watch verifies you are under no physical or emotional stress. You now have access to your life’s savings.
It sounds something out of science fiction, but it’s not. You already use your Apple Watch to track your heart rate during workouts. You most probably enabled fall detection to let loved ones and emergency services know if you had a hard fall. Also, Apple Watch knows when you wear it. This is all possible today.
My concept reimagines this technology and repurposes it for enhanced security by using the body’s stress biomarkers as signals for extra security.
Mind you, this is a concept and an exploration of an idea. I’m not suggesting 3FA should be mainstream, neither it should be Apple doing anything about it.
Because this is a concept, I threw in the mix a couple more sensors. Body temperature and sweat measurement.
The app runs on the iPhone. Apple Watch provides the data. Concept version 1.0.
