That problem is the need to move an "Item/object" from one location to another, have immutable traceability, and the knowledge that the Item went nowhere other than the intended final intended destination.
One solution to this problem uses a tamper-evident seal, printed with a SignaKey. Every SignaKey is unambiguously unique, and the encryption used in the SignaKey is the strongest currently available.
Tamper-evident seals are commercially available in a variety of configurations. The selection criteria for any application depend on the shape and size of the tracked Item/object. Particularly effective designs of tamper-evident seals employ aggressive adhesives with a bond that becomes permanent within minutes of application, paired with a frangible substrate that is exceptionally tenacious. It is practically impossible to remove this type of label without leaving evidence of interference.
One example of Items/objects that would employ this type of solution is Blood and Urine samples collected from thoroughbred horses after a race. These samples check for the presence of illegal performance-changing drugs within the animal. They are taken in the barn/stall by a veterinarian immediately after a race. A tamper-evident seal is attached to the opening of the vial, and the SignaKey immediately decoded. This action records the date/time and geospatial coordinates of the barn/stall.
The vial that contains the blood now moves to the certified independent laboratory. The Labs first action is to confirm that the tamper-evident seal is still intact. If it is, they immediately decode the SignaKey. This action again records the date/time and the geospatial coordinates of the Lab.
The combination of "on-location" scanning within SK Track, and the tamper-evident seal, assures the stakeholders that the blood sample taken from the horse immediately after the race is, without doubt, the one presented to the Lab.
