Tamper-Evident
A physical or digital security mechanism that makes any unauthorised access to an asset, container, or package immediately detectable - leaving visible or auditable evidence of interference.
What tamper-evident means in operations
Tamper-evident security products are designed to make unauthorised access to an asset or package visible - either through physical destruction of the seal, a chemical indicator activated by opening, or a digital alert triggered by a sensor. The key distinction is between tamper-evident (detectable after the fact) and tamper-proof (theoretically prevents access entirely). No physical security product is truly tamper-proof; tamper-evident products make tampering visible and documentable.
In logistics and supply chain operations, tamper-evident products are used to confirm that a consignment, package, or container has not been accessed or interfered with between the point of sealing and the point of opening. This confirmation is only meaningful, however, if there is a digital record linking the tamper-evident product to a specific custody event - otherwise, a broken seal proves access occurred, but not when or who was responsible.
This is the core limitation that Trailio addresses: physical tamper-evidence is made operationally valuable only when it is backed by a digital event record that makes any tampering attributable to a specific custody period.
The physical-digital integration requirement
A tamper-evident seal applied at origin but not scanned into a platform record is of limited evidentiary value. When the sealed consignment arrives with a broken seal, the only evidence is that the seal was broken - not when, not where, and not by whom. Liability attribution is impossible without the scan records that would narrow the tampering window.
Trailio's physical-digital approach resolves this: every HSA tamper-evident product is serialised and registered in the platform at application. Every subsequent custody checkpoint scan records the seal as intact or broken. If a seal is found broken at any checkpoint, the platform immediately narrows the tampering window to the gap between the last intact scan and the current broken-seal scan - making the responsible custody period identifiable.
