Biometrics

Hi,

I don't like asking for help .. can someone check my work please ?

In a biometric system under testing there are 500 users. 200 were legitimate users (authorised), and 300 were not ( unauthorised)

At one threshold the system:-

Shut out 10 individual users it should have admitted, and admitted 2 individual it should have shut out.

What is the false rate match (FMR) at this point ?

is it 2/300 = 0.67% ???

Next the false non match rate

is it 10 / 200 = 5 % ???

If the threshold of the system is now decreased significantly which is the most likely outcome ..

The % of false matches will increase and the % of false non matches will decrease ???

Thank you .. for your kind help and time - I do appreciate it
