Revisiting Authentication

I've been looking at authentication lately and wanted to share three authentication methods I came up with. I think they are new but then I haven't searched in depth to see if anyone else have come up with similar ideas so it's just a guess at this point.
Very Large Key-based SecurID
This idea uses my Very Large Key idea to simulate SecurID-like devices in software. SecurID-like devices, like the fob PayPal will be using, are just random number generators with device-specific seeds. The device generates a random number for each 30 second time slot during which the random number can be used to authenticate with servers that knows the device's seed. If the random numbers are pre-generated (about 168MB for 10 years worth) and saved to a CD or a dumb USB flash drive, the result is similar to SecurID (minus the temper-proof feature that is). Right mixture of auto-play and copy protection schemes can be applied to raise the level of protection beyond sheer size.
DRM-based SecurID
With continuing investment in DRM technologies, DRM support in both hardware and software media players are common. What if one-time passwords are delivered to users as DRM-protected movie or audio streams, displaying or reading out password to the user at the point of entry? One-time passwords are useless to keyloggers and DRM technology offers reasonable level of protections against screen recorders. I don't think password movie streams have to be user-specific if reasonably large number of group streams are available and users are randomly distributed across groups.
F2F Authentication NG
This idea updates the oldest form of authentication, face-to-face interaction, with latest video chat technologies like Skype. At the point of authentication, a video chat session between the user and a verification personnel is started. A verification personnel is a real person who authenticates you by sight, voice, and, if need arises, asks you a few questions before letting you through. F2F authentication is not cost effective enough for average users and situations but I think it will become the preferred authentication method for VIP customers to protect high-value transactions.
That's it for now. Contact me privately (click my face ;-p) if you would like to chat about these ideas.
