Variable pattern shield protection system for a tamper-evident container
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.
1 . A method for securing shipment of goods, the method comprising:
providing a mailing container configured to receive goods, the mailing container comprising a substrate, a conductive pattern comprising one or more conductive elements arranged on the substrate in a pattern that at least partially defines a unique electronically measurable signature based at least in part on a design of the conductive pattern, and monitoring electronics in communication with the conductive pattern;
activating the monitor electronics to:
electronically measure the signature of the conductive pattern by the monitoring electronics;
encrypt the signature based on an encryption key; and
store the encrypted signature in the monitoring electronics; and
after the mailing container is received by a recipient, sending a decryption key corresponding to the encryption key to a computing device associated with the recipient to facilitate detection of a tampering status of the goods.
2 . The method of claim 1 , wherein the decryption key is sent to the computing device associated with the recipient via a remote server.
3 . The method of claim 1 , wherein the decryption key is sent to the computing device associated with the recipient automatically based on an initialization of the monitoring electronics by a computing device associated with a sender of the goods.
4 . The method of claim 3 , wherein the conductive pattern comprises a plurality of traces disposed on an interior side of the substrate.
5 . The method of claim 4 , wherein each trace of the plurality of traces comprises a plurality of conductive contacts.
6 . The method of claim 5 , further comprising electrically connecting the plurality of traces before the monitoring electronics electronically detect the signature.
7 . The method of claim 6 , wherein electrically connecting the plurality of traces comprises closing the mailing container such that individual conductive contacts contact other conductive contacts of the plurality of conductive contacts.
8 . The method of claim 7 , wherein at least some of the plurality of conductive contacts are provided with a conductive adhesive disposed therein.
9 . The method of claim 1 , wherein the conductive pattern comprises one or more traces comprising conductive ink.
