Abstract

The invention provides a digital asset transaction method and device based on a block chain, and a storage medium. The method comprises the following steps: receiving a digital asset transaction request of a transaction initiator, wherein the digital asset transaction request comprises the information of the transaction initiator and a digital asset identifier; determining a transaction receiver according to the digital asset transaction request; when the information of the transaction initiator and the transaction receiver meets the verification condition, generating a digital watermark according to the digital asset transaction request, and generating a digital watermark according to the information of the transaction initiator, the information of the transaction receiver and the digitalasset information; obtaining digital assets embedded with digital watermark according to the digital watermark and the digital asset corresponding to the digital asset transaction request; and sending the digital asset embedded with the digital watermark to the transaction initiator according to the intelligent contract corresponding to the digital asset transaction request. An infringement userwho leaks the digital asset can be accurately positioned, and the digital asset right protection cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of computer and Internet applications, and in particular to a blockchain-based digital asset transaction method, device and storage medium. Background technique [0002] With the continuous development of information technology, both enterprises and individuals may generate data related to themselves in daily production and life, such as digital assets in the form of songs, literary works, pictures, etc. As a kind of sensitive data, digital assets can be centralized in the storage management system to ensure the security and reliability of digital assets to the greatest extent. However, in terms of digital asset transactions, traditional digital asset trading platforms inevitably have problems such as low data credibility, poor privacy protection, and low transaction efficiency due to their centralized characteristics. In order to improve the management and utilization of digital assets and maximize...
