Abstract
The present disclosure relates to a system and a method for a blockchain platform-based service, the method including generating, at a smart contract deployed on a blockchain platform, a pair of a first private key and a first public key, transmitting the first public key generated at the smart contract to a first computing device, receiving, at the smart contract, data encrypted with the first public key at the first computing device, decrypting, at the smart contract, the encrypted data with the first private key, and storing, at the smart contract, the data decrypted with the first private key as a local variable of the smart contract.
Claims10
A system for a blockchain platform-based service, the system comprising at least one processor coupled to a storage device storing instructions, the instructions in response to execution by the at least one processor implementing:
- a smart contract that is deployed on a blockchain platform and generates a pair of a first private key and a first public key;
- and
- a first computing device that receives the first public key generated in the smart contract and transmits data encrypted with the first public key to the smart contract, wherein
- the smart contract decrypts the data encrypted with the first public key with the first private key, and stores the data decrypted with the first private key as a local variable of the smart contract.
A method for a blockchain platform-based service, comprising:
- generating, at a smart contract deployed on a blockchain platform, a pair of a first private key and a first public key;
- transmitting the first public key generated at the smart contract to a first computing device;
- receiving, at the smart contract, data encrypted with the first public key at the first computing device;
- decrypting, at the smart contract, the encrypted data with the first private key;
- and
- storing, at the smart contract, the data decrypted with the first private key as a local variable of the smart contract.
