Method and systems for authenticating and securing physical items with registering a 3D digital representation as a non-fungible token

A method for authenticating and securing physical items, comprising:

• embedding identification marks, stochastically dispersed within at least a portion of the physical item's three-dimensional (3D) structure to form a non-fungible physical (NFP) item, wherein unplanned characteristics of the spatial properties of the identification marks, which are distinct and discernible from its surrounding material, have an infinitesimal probability of replication, wherein the identification marks are permanently fixed and unalterable without damaging the item, and whereby this integration makes it virtually impossible to circumvent the embedding process or create a duplicate item with matching identification marks that would remain undetected during a 3D scan comparison with the authentic item's reference data;
• capturing a 3D digital representation of the unplanned characteristics of the spatial properties of the identification marks embedded within the item and registering the 3D digital representation as a non-fungible token (NFT) on a blockchain;
• thereby creating an immutable digital record of ownership that securely links the unique spatial properties of the identification marks between the item and its corresponding NFT;
• employing at least one of artificial intelligence (AI) and other suitable processing technology to compare the unique spatial properties of the identification marks embedded within a suspect NFP item to the known 3D digital representation of a genuine NFP item stored on the blockchain as an NFT, whereby this method irrefutably determines authenticity and prevents duplication of the NFP item.
