Secure Transaction Mechanism of Blockchain Digital Assets Based on Distributed Identity

Abstract

With the development of the new industrial revolution, data has become an important factor of production. Many physical assets and value data will appear in the form of digital original ecology. Traditional digital asset trading schemes have security problems such as difficulty in confirming the ownership of assets, difficulty in tracing the transaction process, and leakage of identity information. Aiming at the problems of digital asset confirmation and identity information leakage, we propose a secure transaction mechanism of blockchain digital assets based on distributed identity. Aiming at the problems of data leakage and anti-counterfeiting traceability in the process of digital asset transaction, we propose a digital fingerprint embedding scheme based on homomorphic encryption. Finally, it is verified in the digital collection transaction scenario, and deployed on the “Spark Chain Digital Native Asset Service Network” to verify the effectiveness of this mechanism. The scheme ensures the secure and credible sharing of digital assets in the transaction process, and provides a technical path for the future transaction of digital assets in the meta universe.
