I'd have to go plough thru the filings but I don't see a history of press releases each time a patent was granted. Is this patent more significant that the other ones?
I had a quick look at the patent. It looks like it's trammel's previous invention tacked on to a voice print password.
Might be a nifty idea, who knows. Just guessing but if voice prints were effective encryption why aren't they used? Voice prints aren't a new notion.
Does the addition of Trammel features improve key encryption? If so, if the technology is ready (not just conceptual) and is useful for mobile phone security etc, why is no one using this improved version?
