Abstract
A physical uncloneable function (PUF) pattern is used for verifying a physical condition of an item. The PUF pattern is arranged to be damaged in the event that said item is exposed to a predetermined environmental condition. Verification of the physical condition of the item, is carried out by obtaining a measured response from the PUF pattern, and comparing the measured response with a stored response in respect of the PUF.
