Blockchain-based food product shelf-life management
A blockchain of transactions may be referenced for various purposes and may be later accessed by interested parties for ledger verification. One example method of operation may comprise one or more of identifying a production date associated with a product, creating a unique code to represent the production date and the product based on a hash of one or more blocks of a blockchain, and forwarding the unique code to a verification server to verify the product.
1. A method implemented by a computing system, the method comprising:
identifying a last block created in a particular time period in a ledger of a blockchain, the last block containing a hash value, a production date of a product, and a production time of the product;
periodically generating, using a rule stored on the blockchain, an enhanced product code representing the production date, the production time, and the product based on a sub-hash of the hash of the last block and a unique product code of the product; and
forwarding the enhanced product code to a verification server to verify the product.
2. The method of claim 1 , further comprising:
selecting the one or more blocks from the blockchain; and
retrieving the hash of the one or more blocks.
3. The method of claim 1 , further comprising:
storing the enhanced product code in the blockchain.
4. The method of claim 1 , wherein the product is a perishable product with a shelf-life period of time.
5. The method of claim 1 , further comprising:
creating a shelf-life period of time starting from the production date;
creating an alert when the period of time has expired; and
transmitting the alert to an interested party identified from the enhanced product code.
6. The method of claim 1 , wherein the rule is changed dynamically or randomly.
7. The method of claim 6 , wherein the hash of the one or more blocks specified by the rule provides a basis for a creation date and an expiration date of the product.
8. The method of claim 1 , wherein the sub-hash comprises a predetermined number of last digits of the hash.
9. An apparatus, comprising:
a processor configured to:
identify a last block created in a particular time period in a ledger of a blockchain, the last block containing a hash value, a production date of a product, and a production time of the product;
periodically generate, using a rule stored on the blockchain, an enhanced product code representing the production date, the production time, and the product based on a sub-hash of the hash of the last block and a unique product code of the product; and
forward the enhanced product code to a verification server to verify the product.
10. The apparatus of claim 9 , wherein the processor is further configured to:
select the one or more blocks from the blockchain; and
retrieve the hash of the one or more blocks.
11. The apparatus of claim 9 , wherein the processor is further configured to:
store the enhanced product code in the blockchain.
12. The apparatus of claim 9 , wherein the product is a perishable product with a shelf-life period of time.
13. The apparatus of claim 9 , wherein the processor is further configured to:
create a shelf-life period of time that starts from the production date; and
create an alert when the period of time has expired, wherein
the transmitter is further configured to transmit the alert to an interested party identified from the enhanced product code.
14. A non-transitory computer readable storage medium storing one or more instructions that when executed by a processor cause a processor to perform:
identifying a last block created in a particular time period in a ledger of a blockchain, the last block containing a hash value, a production date of a product, and a production time of the product;
periodically generating, using a rule stored on the blockchain, an enhanced product code representing the production date, the production time, and the product based on a sub-hash of the hash of the last block and a unique product code of the product; and
forwarding the enhanced product code to a verification server to verify the product.
15. The non-transitory computer readable storage medium of claim 14 , wherein the one or more instructions are further configured to cause the processor to perform:
selecting the one or more blocks from the blockchain; and
retrieving the hash of the one or more blocks.
16. The non-transitory computer readable storage medium of claim 14 , wherein the one or more instructions are further configured to cause the processor to perform:
storing the enhanced product code in the blockchain.
17. The non-transitory computer readable storage medium of claim 14 , wherein the one or more instructions are further configured to cause the processor to perform:
creating a shelf-life period of time starting from the production date;
creating an alert when the period of time has expired; and
transmitting the alert to an interested party identified from the unique code, and wherein the product is a perishable product with a shelf-life period of time.
