A Blockchain-Based Approach to Precise Accountable Resource Sharing
摘要
Serious copyright infringement has become a critical issue in the widespread application of e-education and e-learning, as every link in the data flow has the potential to access complete data. In practice, entities that come into contact with the data may maliciously sell it, leading to copyright infringement. Previous efforts to prevent data leakage in intermediate circulation links have focused on access control, overlooking the copyright infringement of electronic education data by data requesters. To address these challenges, this paper proposes a traceability and accountability architecture for resource sharing, namely a malicious environment blockchain traceability architecture (MEB) based on multiple watermarks and oblivious transmission. The architecture first uses multiple watermarks and oblivious transmission to prevent false accusations and data leaks, then carries out evidence storage through the blockchain, third, finally carries out trials through the evidence on the blockchain after data leaks. We theoretically analyze the security of the scheme and verify its performance.
