Passwords work great, people just do not know, how to use them properly, so they are looking for an easy fix, but anything easy is also easily by-passable.
I just realized that it might not be easy. How, even after my heartbeat was recorded, would someone pass that into the reader? I'm quite sure the reader won't identify a victim's recorded waves as being legit, because in the process of putting those recorded waves out (like with a speaker) you'd lose it's uniqueness electrical wave lenght and format.
What will you do when your heart goes into atrial fibrilation or any other abnormal rhythm? Will you loose all of your data?
Die? And the article says the rithm doesn't matter, it's the wave lenght that is unique because of the heart shape and the veins/arteries configuration.
That is fine, but most people do not know that, not to mention, that webpages have flawed password management as well. Allowing users to login without an encryption and storing passwords unencrypted. Paypal in all its glory prevents users from creating a secure password, I wonder, if that is on purpose.
Wavelenght? You mean EKG which means ElectroKardioGram which basically is wavelength. And no, you can live a healthy life with atrial fibrilation. Also you can live a long life after one heart attack and your EKG aka wavelenght will be different. Also not to mention that electrolyte inbalance will change your EKG. Lets say you have hypokalemia because of chronic diarrhea, you will have changes in EKG...
