Cloud data management has significant benefits for data storage and processing. However, it also brings some security concerns, such as the integrity of data and the reliability of online verification. To solve this problem, this paper proposes a blockchain and edge computing based public audit scheme, which is different from the traditional third-part auditor and the common blockchain-based two-party audit scheme. Specifically, this public audit scheme consists of data owners, edge computing servers, and cloud service providers. According to privacy data, a data owner generates lightweight verification labels and homomorphic hashes, and updates them on the blockchain. A completeness proof based on homomorphic hashes is computed by edge computing servers. In addition, the proposed scheme theoretically is capable of achieving 100% audit confidence. Security analysis shows that it can avoid the fraud of cloud server provider and data owner in the audit process, and has a strong ability to resist malicious attacks. Experimental results show that the proposed scheme outperforms the existing scheme in the computational cost of completeness verification.
