DATA ASSET MANAGEMENT METHOD, DATA ASSET MANAGEMENT DEVICE AND COMPUTER READABLE MEDIUM

摘要

Disclosed are a data asset management method, a data asset management device and a computer readable medium. The method comprises: a system node receiving a request for data asset extraction;acquiring from a consortium chain ledger first identity mapping information corresponding to a first user address identifier, the first identity mapping information including the first user address identifier, a first public key, and a first identity fingerprint; after using the first identity fingerprint and first encrypted identity information to authenticate a first user, using data information corresponding to a first identity identifier in a first public key encryption system node to obtain a first encrypted data asset; adding the first encrypted data asset to a data asset account of the first user in the consortium chain. The method can effectively collect private data scattered in various systems, and can also effectively manage private data assets.
