Abstract
This invention relates to a method and system for auditably authenticating the histories of events (e.g. temperature levels) experienced by objects (e.g. pharmaceutical products, foodstuffs, etc.) during storage in repositories such as warehouses and movable shipping vehicles. The method involves a) sensing an event experienced by an object; b) recording an event signal that defines the sensed event; c) transmitting a temporally ordered series of the event signals to a data storage apparatus, the data storage apparatus being operable to store the temporally ordered series of the event signals; and d) safeguarding the aforesaid data storage apparatus against alteration of the stored series of event signals.
