Designed or constructed to prevent or resist fraud; impossible or extremely difficult to defraud or deceive.
From 'fraud' (Latin 'fraus', deceit) + 'proof' (from Old French 'prove', able to resist). The compound follows the pattern of '-proof' words like 'waterproof' and 'fireproof'.
'Fraudproof' is a modern coinage that reflects increasing concern about fraud in digital commerce—every time technology evolves, fraudsters adapt, making true 'fraudproof' systems almost mythical.
