"If they try to cloud this, it's a bad idea unless the cloud is your iCloud and it's secure. You can't change your iris. You can't change your thumbprint. That's the reason I've hated biometrics. Once you've compromised your palm print what are you going to do? You can use the other palm, but what happens next?" Disabato asked.
Disabato is betting Apple will see this technology as an opportunity to implement a unified, single sign-on to all Apple devices a consumer owns. Consumers who own a MacBook, an iPhone and an iPad could link all three together on iCloud and sign in with a fingerprint swipe.
"As soon as I buy a new iPhone and sync it up, it would be secure. I would just rub my finger across it. Apple needs to make real sure, however, that the biometric information is not a centralized database -- it needs to be linked only to your iCloud account," Disabato told us.
"So if I decide I want to leave my iCloud account I don't have to worry about my biometrics sitting on some server like Google does with all my e-mail. This is an important design point."
