The invention discloses a digital asset right confirmation distribution authentication system, and belongs to the technical field of computer programs. Based on data storage in a data lake in a distributed storage system, after the stored data is subjected to ownership certification, the data (group) subjected to ownership certification is subjected to ownership certification distribution, so that the ownership, the use right and the operation right of data assets are proved to be clear, and the ownership of the data can be confirmed and digital asset information can be generated by the ownership certification distribution system. When a user obtains a data use right through an allowed access right or purchase right mode, the system can automatically pull up the certification mechanism to carry out certification of the block chain sub-chain again so as to establish the delivery and delay of the distribution (use) right of the group of data (including but not limited to pictures, videos, texts and documents). The system encryption system adopts a block chain technology and a quantum computing decoding avoidance mechanism, so that the overall security of the system is fully guaranteed, and the security of digital assets of users is guaranteed.
