Patent attributes
The disclosed embodiments provide a method for tamper-evident shipment or storage of goods. An Electrical Shield pattern is embedded in or printed on a substrate with other electrical, optical, and electronic components, communication components, semiconductors, which are attached or printed on a substrate to form a shipment bag used as a shipping container. The shield pattern can be made variable between different bags by using algorithms entered into a printer control system. The shipment bag with its components can then be assigned a unique signature which differentiates each bag. Application of encryption methods serves to guarantee the shipped goods are authentic and that were not tampered with during shipment. Digital signal processing is used to generate pedigree information, which may include items such as shipping location, serial numbers, sensor information, and lot numbers for the goods. The information related to the history of tampering attempts and other sensor status can be placed in encrypted form in an RFID tags or control or monitoring electronics which can be read by a mobile phone application or sent to a remote cloud-based server.
