Re: No better than passwords
I see your point, Steve. If you have a line up of prints, it's not much different from typing in an order of characters. But, as the other commenter said, finger prints cannot be written down, or accidentally shared with someone. Also, phishing for a print isn't easy, because in order to use the value the phisher receives, they have to know the hash and salt of the program that they are trying to get into. Lifting and replaying prints is delicate work, from my understanding. And while it might seem easy to find and lift a print, imagine having to lift all ten, and then trying to figure out which ones to use, and what order to use them in, to get access. Passphrases can be typed, read, written down, guessed...etc. You can't do any of these with a fingerprint.

thought provoking
Sir,


I really enjoyed reading your article....especially the last line about toes. Would that constitute 'toe factor authentication'? Haha..excuse my dry british humor.


Cheers!

Interesting, I'll have to look into them (or have my Aussie colleagues do so).

Re: Actually Ardeun is ....
It's good to hear some real-world example that biometrics are working. I have TouchID on my iphone5 and its fast, simple and very reliable. Nothing is perfect, of course, but what we have now (passwords) is barely adequate to the task. I hope we see some progress in this area in the months and years to come.

Actually Ardeun is ....
Great article and good commentary on the SALTed and HASHed values.

On the point of "fingerprint phrases" actually a company called Ardeun Biometrics does use this and other techniques in their Biometric Authentication solution. They encompass a number of modes of biometrics selected by the user or the company wanting to be secured, namely finger and face, or face and voice, or finger and voice etc etc. On the finger side of things, they also have combinations of fingers that can be used to authenticate. Likewise there is also a very simple single scan for fast and easy access where a lesser concern for security exposure exists yet true authentication is required.

I mention this because we use Ardeun in our company and it has been great. Fast access and also all staff are identifiable without question.

Re: Glad to see you shoot down a few biometric canards...
Well that's a new one for me: a biometric wristband that authenticates the identity of the wearer using their unique cardiac rhythm (electrocardiogram – ECG). Cool!

No better than passwords
So let me get this straight. Dave Kearns accepts that fingerprints can be stolen and replayed. So he suggests that a countermeasure to biometric identity theft is to have users memorise a secret sequence of fingers which only they know. Like "left pinky, right middle, left index, left index, right ring" - presto. 

And how is this better than a regular passphrase?
