Managing assets with expiration on a blockchain
An example operation may include one or more of identifying an expiration date associated with an asset, creating a blockchain transaction identifying the asset and the expiration date, storing the blockchain transaction on a blockchain, identifying a requesting entity with a certificate permitting access to the asset, and providing the requesting entity with access to the asset provided the expiration date is still pending.
1. A method, comprising:
receiving, via a first entity, an asset owned by a user;
generating a hash value based on a combination of an identity of the user, an identity of the first entity, and an identity of a second entity that is allowed to receive access to the asset of the user from the first entity;
generating a blockchain transaction which includes the hash value and an expiration date identifying when access by the second entity to the asset of the user via the first entity expires; and
storing the blockchain transaction on a blockchain.
2. The method of claim 1 , wherein the asset comprises a medical record of the user which is being shared by the first entity with the second entity for a limited time.
3. The method of claim 1 , further comprising:
creating a smart contract comprising asset release requirements to access the asset in the blockchain transaction, wherein the asset release requirements comprise a certificate of the first entity.
4. The method of claim 1 , further comprising:
storing the asset in a temporary database outside the blockchain.
5. An apparatus, comprising:
a processor configured to:
receive, via a first entity, an asset owned by a user;
generate a hash value based on a combination of an identity of the user, an identity of the first entity, and an identity of a second entity that is allowed to receive access to the asset of the user from the first entity;
generate a blockchain transaction which includes the hash value and an expiration date identifying when access by the second entity to the asset of the user via the first entity expires; and
store the blockchain transaction on a blockchain.
6. The apparatus of claim 5 , wherein the asset comprises a medical record of the user which is being shared by the first entity with the second entity for a limited time.
7. The apparatus of claim 5 , wherein the processor is further configured to create a smart contract comprising asset release requirements to access the asset in the blockchain transaction, wherein the asset release requirements comprise a certificate of the first entity.
8. The apparatus of claim 5 , wherein the processor is further configured to store the asset in a temporary database outside the blockchain.
9. A non-transitory computer readable storage medium configured to store one or more instructions that when executed by a processor cause the processor to perform:
receiving, via a first entity, an asset owned by a user;
generating a hash value based on a combination of an identity of the user, an identity of the first entity, and an identity of a second entity that is allowed to receive access to the asset of the user from the first entity;
generating a blockchain transaction which includes the hash value and an expiration date identifying when access by the second entity to the asset of the user via the first entity expires; and
storing the blockchain transaction on a blockchain.
10. The non-transitory computer readable storage medium of claim 9 , wherein the asset comprises a medical record of the user which is being shared by the first entity with the second entity for a limited time.
11. The non-transitory computer readable storage medium of claim 9 , wherein the processor is further configured to perform:
creating a smart contract comprising asset release requirements to access the asset in the blockchain transaction, wherein the asset release requirements comprise a certificate of the first entity.
12. The non-transitory computer readable storage medium of claim 9 , wherein the one or more instructions are further configured to cause the processor to perform:
storing the asset in a temporary database outside the blockchain.
