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

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. L'invention concerne un procédé de gestion d'actifs de données, u
