Although Dialog Communication Systems warns that the need to memorize a flood of passwords and PINs is overwhelming end users, the same might be said of biometric security devices and IT managers.
At least Dialogs BioID Soho 1.0, available as a trial download from www. bioid.com, uses regular PC video and sound equipment to authenticate users based on a combination of voice, lip and facial recognition. The product worked well, although I had initial setup difficulties, including making sure I was in an area with enough light.
This will likely make a decent authentication system for IT managers who need to make sure that employees working at home or in remote offices are the only people accessing a protected computer. As with most other biometric products, BioID Soho 1.0 is still difficult to manage from a central location. This must be improved before it will be useful to most enterprises.
