摘要

大多数云服务提供商(CSP)都按照一定的原则存储和删除客户数据。大多数云服务提供商都将其云平台设计为具有极高的一致性、速度、可用性和耐用性。他们的系统在构建时考虑到了这些性能特征,同时必须谨慎平衡确保精确和快速删除数据的要求。在公共区块链中,本文建议采用快速内容定义的 Chunking 算法来进行数据复制。个人和组织经常将急性数据外包给遥远的云服务器,因为这样做可以大大减少维护基础设施和软件的麻烦。然而,由于用户数据是传输给云存储提供商并存储在远程云上的,因此所有权和控制权是分离的。因此,用户在尝试确认私人信息的完整性时面临着巨大挑战。实验结果表明,所建议的动态分块具有与固定长度分块相当的快速处理时间,并显著提高了重复数据删除的处理能力。

Enhancing Cloud Data Deduplication with Dynamic Chunking and Public Blockchain
The majority of cloud service providers (CSPs) store and remove customer data according to certain principles. The majority of them have designed their cloud platform to have very high levels of consistency, speed, availability, and durability. Their systems are built with these performance characteristics in mind, and the requirement to ensure precise and rapid data deletion must be carefully balanced. In the public blockchain, this paper suggests employing the rapid content-defined Chunking algorithm for data duplication. Acute data is frequently outsourced by individuals and organizations to distant cloud servers since doing so greatly reduces the headache of maintaining infrastructure and software. However, because user data is transmitted to cloud storage providers and stored on a remote cloud, ownership and control rights are nonetheless separated. Users thus have significant challenges when attempting to confirm the integrity of private information. According to the experiment results, the suggested dynamic chunking has a fast processing time that is on par with fixed-length chunking and significantly improves deduplication processing capability.
