Make no mistake about it. As we move closer to a point in time when the iPhone could double as an iWallet, security will be the killer feature that consumers will demand. Two weeks ago Apple introduced us to one of their future security systems that will handle auto login using advanced facial recognition technology. That'll be great for iDevices not handling important documents and/or financial instruments such as debit and/or credit. For that, Apple has invented a heavy duty second tier of security that is quite ingenious. The key rests in splitting a user's password recovery secret amongst two devices that are never carried together at one time. And you know it's a serious security project at Apple when Bud Tribble, Apple's VP of Software Technology, is the man behind this endeavor.
