- W2366739305 abstract "In the cloud computing applications,data security is the first concern to users,so the data security,in the cloud,becomes the current research focus.The open source cloud computing storage system HDFS can't completely destroy data,which may lead to data leak.To solve this flaw,design a multi-grade safety data destruction mechanism of HDFS.This mechanism can effectively prevent malicious data recovery and prevent data leak,destroy data completely by overwriting original data with overwrite algorithm before deleting data.Moreover,the mechanism can balance the safety requirement and performance requirement by using different overwrite algorithm according to different safety requirement.The simulation experiment shows that the mechanism can effectively overwrite the file of Block to destroy original data completely in HDFS.And the spending time of different overwrite algorithm is different,so it can keep efficiency and safety balance." @default.
