【Abstract】With the emerging of blockchain technology, new technical solutions are available for secure storage and trusted computing in the data traceability. However, there are a number of problems with blockchain-based traceability systems. Firstly, querying the historical data of the blockchain is not efficient, becoming a critical performance bottleneck in traceability systems. Secondly, most of blockchain-based traceability systems are not well designed in terms of data privacy and access control. To address the above issues, we propose an efficient and secure blockchain-based traceability system. Specifically, we design a Merkle tree independent index structure that aims to support efficient traceability queries. In addition, we deeply integrate the system with cloud computing technology, and utilize searchable encryption and attribute-based encryption to achieve secure data storage and fine-grained access control. Finally, we simulate and evaluate our system in Hyperledger Fabric. The simulation results demonstrate that the proposed system has better execution efficiency.
