Abstract

Embodiments of the present invention provide a method for processing privacy data based on a block chain. The method includes receiving an authorization request including an address of an authorized account on the block chain, a public key of the authorized account, and a privacy data identifier. Obtaining encrypted first privacy data associated with the privacy data identification from the ledgerof the block chain; decrypting the encrypted first privacy data and obtaining second privacy data by encrypting at least a portion of the decrypted first privacy data using the public key; generatinga query intelligent contract for querying the second privacy data according to at least the address of the authorized account and the second privacy data; and returning an address of the query smartcontract. The method according to the embodiment of the invention can precisely control the privacy data in the account book of the block chain, so as to ensure that the privacy data will not be obtained by an unauthorized individual or an organization, and the privacy of the data is ensured.

Description

technical field [0001] Embodiments of the present invention relate to blockchain technology, and more specifically relate to a method for processing private data based on blockchain, a device for performing the above-mentioned method for processing private data based on blockchain, and a A corresponding computer-readable storage medium. Background technique [0002] Blockchain is an intelligent peer-to-peer network that uses distributed databases to identify, disseminate and record information, also known as the Internet of Value. Blockchain has technical advantages such as decentralization, anti-tampering, consistent data storage, transparent and traceable process, etc. It is considered to have a wide range of applications in many fields such as finance, credit investigation, Internet of Things, economic and trade settlement, asset management, etc. prospect. [0003] A smart contract is a computer protocol designed to disseminate, verify or enforce a contract in an inform...
