Anti-tamper software Anti-tamper software (or tamper-resistant software) is software which makes it harder for an attacker to modify it. The measures involved can be passive such as obfuscation to make reverse engineering difficult or active tamper-detection techniques which aim to make a program malfunction or not operate at all if modified. It is essentially tamper resistance implemented in the software domain. It shares certain aspects but also differs from related technologies like copy protection and trusted hardware, though it is often used in combination with them. Anti-tampering technology typically makes the software somewhat larger and also has a performance impact. There are no provably secure software anti-tampering methods, thus the field is an arms race between attackers and software anti-tampering technologies.
