Abstract
A system for secure and verifiable transfer of valuable physical goods includes a card that has a public key and one or more private keys that are obscured. When ownership transfer occurs, a private key from the card is revealed and scanned. A computer system then decrypts a blockchain, generates a new block and adds it to the chain to record the transfer of ownership. The card limits the amount of transfers of a good to control the movement of the legitimate goods and preserve provenance.
Claims18
A system for securely verifying and tracking ownership of a limited good, comprising:
- a public key affixed to a physical good;
- a card comprising:
- a copy of the public key imprinted on the card;
- a first private key imprinted on the card, the first private key obscured by a first single-use cover;
- at least one second private key imprinted on the card, the at least one second private key obscured by at least one second single-use cover;
- and
- a computing system programmed to:
- receive a scan of the public key;
- generate a first block on a blockchain based on the scan of the public key;
- encrypt the blockchain using the public key;
- receive a scan of the first private key and at least one item of ownership information, the at least one item of ownership information reflecting a change in ownership of the physical good;
- decrypt the blockchain using the first private key;
- and
- generate a second block on the blockchain based on the scan of the first private key, the second block including a second record of ownership based on theat least one second item of ownership information.
A system for ensuring secure transfer of valuable goods, comprising:
- a card including at least:
- a first private key;
- a first public key corresponding to the first private key, wherein the first public key comprises a first information address for a digital record corresponding to a real-world good;
- a second private key;
- a second public key corresponding to the second private key, wherein the second public key comprises a second information address for a second digital record corresponding to the real-world good;
- a computing device programmed to:
- receive a scan of the first public key from a user device operated by a user;
- obtain the first information address for a digital record of the real-world good based on the first public key;
- receive a scan of the first private key from the user device;
- link the first information address of the real-world good to a digital wallet associated with the user based on the first private key;
- and
- record the link as a transaction in an existing blockchain.
