When your voice will no longer be your password

From Guido, the globetrotting, hyperconnected mind behind Globally Connected: Vocal tract models are getting us closer to flawlessly imitating anybody's voice. The label of "vocal terror", of course, is idiotic, and in any case if imitating voices is enough to crack your security, you had a lousy security model to begin with (of course, mostly everybody does have a lousy security model, which makes possible things like social engineering hacks).

But if you want silly, vulnerable, expensive technological fixes to what are essentially systemic problems, let me suggest to you implantable devices that add an encrypted authentication signature to your voice on some barely-audible frequency. It won't make your system secure, but it will certainly look cool on your resume.
