多云环境下的数据隐私:一个增强的数据分片框架

Data Privacy in Multi-Cloud: An Enhanced Data Fragmentation Framework

Randolph Loh, Vrizlynn L. L. Thing

摘要:

数据拆分通过将数据划分为各种片段进行远程存储和共享来保护隐私。它支持大多数数据操作,因为数据可以以明文存储,而不是依赖于加密的方法。然而,大多数现有的数据拆分技术不考虑已经在多云中的数据。这导致不必要地使用资源来将数据重新拆分为片段。这项工作提出了一个利用多云中现有数据的数据拆分框架。它通过减少拆分操作和产生的碎片的数量来改进数据拆分机制。因此,减少数据所有者管理的存储位置的数量。广播查询定位第三方数据片段,以避免在分割数据时进行代价高昂的操作。这项工作探讨了使用第三方片段和应用现有的数据分割技术的考虑因素。拟议的框架也适用于现有的数据拆分机制,以补充其功能。

英文摘要:

Data splitting preserves privacy by partitioning data into various fragments to be stored remotely and shared. It supports most data operations because data can be stored in clear as opposed to methods that rely on cryptography. However, majority of existing data splitting techniques do not consider data already in the multi-cloud. This leads to unnecessary use of resources to re-split data into fragments. This work proposes a data splitting framework that leverages on existing data in the multi-cloud. It improves data splitting mechanisms by reducing the number of splitting operations and resulting fragments. Therefore, decreasing the number of storage locations a data owner manages. Broadcasts queries locate third-party data fragments to avoid costly operations when splitting data. This work examines considerations for the use of third-party fragments and application to existing data splitting techniques. The proposed framework was also applied to an existing data splitting mechanism to complement its capabilities.
