What is "tamperproofing"

Tamperproofing is a term sometimes used for a methodology used to hinder, deter or detect unauthorised access to a device or circumvention of a security system.

Since any device or system can be foiled by a person with sufficient knowledge, equipment, time, etc., the term "tamperproof" is a misnomer. Tamper resistance and tamper-evident systems and devices are better terminology.
