I think you are confusing iris scanning with retinal scanning.
Probably a little actually, though it doesn't help that hardware vendors screw this up as well.
As for your claims that biometrics like retinal scanning is some secret process that governments keep to themselves its no secret how it
I don't think you understood what I was saying at all. (And kind of sensing more than a little attitude and condscending frankly; expect a short
The pattern of variations is converted to computer code and stored in a database
The algorithms that are involved have been obsfucated quite often the same way as forensics techniques have been hidden from the public. This is very
common, though its been changing over the years as there has been a push for more transparent counter forensic studies etc ...
Your claims of hacking and 0day exploits are pretty much redundant in a closed system ie something that is not hooked up to the
There are multiple journal articles from the last five years alone that discuss issues of these systems being vulnerable to basic techniques and how
to secure them. (Algorithms are a large part of that)
I am not referring to anything related to the internet, though a school would often at least have a database going through the on-campus intranet, and
education departments aren't so well know for their network security.
Either way the machine that does the authentication is only part of a computer system and is not really effected by hacking.
A broadcast attack isn't a 'hack' as you seem to think.
It can be, such as digitally altering a video feed. but it certainly doesn't need to be. It can be something as simple as replacing the live image
(camera) with a rebroadcast one (recording or photography), and can also include physical interference with the device itself.
I do find that image forensics and more traditional digital forensics sometimes use some of the same language but in slightly different contexts which
may be leading to some confusion which may be occurring here.
At the end of the day its super difficult to beat biometrics
We will have to agree to disagree frankly.
I've seen facial and eye recognition systems exploited multiple times and with audiences; you have to have a certain level of confidence to do that.
You can certainly do it with laptops and several phones quite easily still. You might state these pieces of hardware are 'cheap', however they are
still a 'biometric' leading me to believe your statement isn't 100% accurate. Not to mention all the different types of 'biometrics' there are.
We can enter into the debate about $10, 000 'government' systems vs $2000 cheap Toshiba laptops, all kinds of details about what you consider
biometric and not, what you consider professional and not etc etc etc ... but to be honest I kind of get the impression it would be more about trying
to prove me as wrong possible rather than learning, education, or understanding. It's a discourse I have no interest in.
even more difficult on a closed system and a very practical security method for something like schools.
I actually think it's dangerous, personally. I wouldn't want anyone using my child as a human barcode scanner.
I hope this clears my position a little more. Have a good day.
