Here I go.
Your face or heartbeat could be the key to a future without cumbersome passwords.
All right, let's see if I can login with my face.
And I'm in.
Intel's True Key is a password manager that uses facial recognition.
You can't get into your devise unless it recognizes your face.
Then it fills in your passwords for different sites, so you don't have to remember them.
And as soon as True Key gets enough information to know that.
I'm not a picture of me or a video of me, but a real live person.
It'll say, okay.
The technology's designed so it can work around facial hair, hairstyles and glasses.
We take measurements of over 100 different points on the face.
Facial recognition is also coming to home security and monitoring cameras, like ArcSoft Simplicam.
You register different people's faces.
And when the camera detects that face or an unfamiliar face, you can receive a customized alert.
The Nymi band uses something inside your body, your heartbeat.
It reads your electrocardiogram, or the electrical current your heart generates.
When I put my finger on it, that will complete the circuit.
And the Nymi Band will then be able to actually read my ECG.
It's not reliant on your pulse, and it's not a heart rate monitor.
Is the unique characteristics that are within your ECG.
That's what we use to actually create our algorithm, to create the digital signature.
Its first application can unlock a Windows computer without a password.
Nymi's also working with MasterCard to test payments with the band.
So in the future, instead of keys and a wallet, all you may need when you walk out of the door is you.
In San Francisco, I'm Kara Tsuboi.
