A “false positive” is when a check or a test wrongly identifies a match of criteria, although this is not the case. It is not uncommon to speak of a “false alarm” in this context.
In fraud prevention, a false positive is understood to be a legitimate transaction that is falsely identified as fraudulent and rejected.
As a result, your company misses out on what is a “good” order and the associated turnover – and an honest customer is put off. Your goal should therefore be to keep the false positive rate as low as possible.
