Biometrics and facial recognition

Caute_cautim — Mon, 22 Jul 2019 21:41:10 GMT

For those who want to avoid facial recognition systems currently - the Chinese have pointed out a 30 percent error rate for those with beards - an obvious message there. Now the US have pointed out they are having problems with people with a dark complexion - which appears to have an error rate of 20 percent.

So for identification purposes alone, it is insufficient without additional controls.

And just why do you think greybeards *have* beards?

@rsladeI am sure there is a rationale behind your question about greybeards?

Either they are time honoured and highly distinguished people or the fact they could of the male persuasion ask suggested by Google and Gamer's links.

Or you have you have a great explanation?

Isn't it just the data set these algorithms have been trained on that skews the results?

If the input dataset is hairless white caucasian almost exclusively then I'd expect beards (what's that!) and darker skin tones to result in a higher false positive identification rate.

@Steve-WilmeYes, in terms of the input data provided to the systems to learn and develop. It also depends on the ethics and integrity of the scientists or developers creating the systems too - there can also be inherent bias, on the decisions made without them actually realising.

Well, I'll get on with growing the beard and tanning then.

My wife and daughter are out of luck...
