Tamper-evident is a term used to describe a type of security feature that helps to identify whether an item or product has been tampered with or not. This term is quite common, but there are several synonyms that can be used in its place. For example, 'anti-tampering' can be used to describe a feature that deters tampering. 'Authentication' is another synonym that can be used to represent a feature that authenticates a product's integrity. Other synonyms include 'sealed', 'impervious' and 'unbroken', as they all convey the same meaning as tamper-evident. Regardless of the synonym used, the key goal is to ensure that products remain uncompromised and authentic for the end-users at all times.
