I wanted to write a list of the biometric modalities for which I provide experience.
So I started my usual list from memory: fingerprint, face, iris, voice, and DNA.
Then I stopped myself.
My experience with skin goes way beyond fingerprints, since I’ve spent over two decades working with palm prints.
(Can you say “Cambridgeshire method”? I knew you could. It was a 1990s method to use the 10 standard rolled fingerprint boxes to input palm prints into an automated fingerprint identification system. Because Cambridgeshire had a bias to action and didn’t want to wait for the standards folks to figure out how to enter palm prints. But I digress.)
So instead of saying fingerprints, I thought about saying friction ridges.
But there are two problems with this.
First, many people don’t know what “friction ridges” are. They’re the ridges that form on a person’s fingers, palms, toes, and feet, all of which can conceivably identify individuals.
But there’s a second problem. The word “friction” has two meanings: the one mentioned above, and a meaning that describes how biometric data is captured.
From https://www.youtube.com/watch?v=4XhWFHKWCSE.
No, there is not a friction method to capture faces. Squishing
- If you have to do something to provide your biometric data, such as press your fingers against a platen, that’s friction.
- If you don’t have to do anything other than wave your fingers, hold your fingers in the air, or show your face as you stand near or walk by a camera, that’s frictionless.
More and more people capture friction ridges with frictionless methods. I did this years ago using MorphoWAVE at MorphoTrak facilities, and I did it today at Whole Foods Market.
So I could list my biometric modalities as friction ridge (fingerprint and palm print via both friction and frictionless capture methods), face, iris, voice, and DNA.
But I won’t.
Anyway, if you need content, proposal, or analysis assistance with any of these modalities, Bredemarket can help you. Book a meeting at https://bredemarket.com/cpa/
