Co-Work：基于HDFS的安全云存储数据一致性保持算法
Co-Work:Data consistency preserving algorithm based on HDFS in se-cure cloud storage system
摘要
Abstract
To guarantee the privacy protecting and sensitive data storage in cloud storage, this paper presents a consistency preserving algorithm, Co-Work, based on the actual scene and lock mechanism which can be implemented in ASOM(All Self-Organization Model). Co-Work algorithm can keep consistency between the metadata server and the storage device through a random map. Experimental results show that the ASOM model implemented Co-Work algorithm can isolate the physical data from logical data, avoid the autonomous users to control and manage the metadata, and increase the data transport efficiency. The read/write efficiency can be increased by 12%when the file size reachs 1 GB.关键词
