METHOD FOR ENSURING THE AUTHENTICITY AND VALIDITY OF ITEM OWNERSHIP TRANSFER

摘要

The present invention describes a method for a secure crossover hashing process of an item's physical identity and digital identity. Three layers are involved in the method of the invention which are the physical layer (303), database layer (302) and blockchain layer (301). The digital item identity in the digital layer stores the digital item's identity (213) as a database table record in a relational database management system (217). The physical item identity is stored in a NFC or RFID tag. The invention performs multi-layer hashing of the item's physical identity and digital identity to ensure the authenticity of the item as well as its physical identity and digital identity. The invention further verified and secures the item's ownership history by an information hashing process with blockchain distributed ledger technology.
