Discover the difference between tamper-evident and tamper-proof seals. Thursday 19 March 2015 @ 15:25

The interpretations of fool-proof is that it is impervious to error. This could lead you to believe that tamper-proof means that you could not tamper with a seal. So with that way of thinking in mind, no security seal could accurately be called tamper-proof.

However a common meaning of proof in tamper-proof lies within the definition of the word proof. Proof meaning evidence. So the terms tamper-proof and tamper-evident are interchangeable.

Security seals have a wide variety of features that are used to illustrate proof of tampering. This can include unique serial number authentication, material blushing on manipulated plastic seals and fraying cable strands from removed cable seals. Some security labels and tapes display a void message that offers proof of tampering.

Example of a Tamper Proof Seal

The conclusion that Harcor came to, was not to call their security seals tamper-proof but instead use the words tamper-evident, to avoid any confusion and for uniformity when supplying customers with content.

It is not a completely incorrect premise that security seals not only show evidence of tampering but can also physically stop tampering. Having a tamper evident security sealing system in place will definitely be an intrinsic deterrent to tampering. In addition to that, certain security seals offer high levels of physical security. A high security wide diameter cable seal would require bolt cutters for removal, not always on hand for a would be thief. The Sea Lock barrier seal requires a power cutting tool such as an angle grinder for removal, also not normally casually carried around.
