Problems solved by technology

[0006] Taking advantage of the data leakage caused by the above reasons, malicious users or cloud service providers can restore and use the data that ordinary users have deleted, harming the interests of users and even causing more serious harm
Therefore the present invention is aimed at the problem that the data in the Hadoop file system cannot be completely destroyed, provides a kind of method that the concurrent high-speed data of Hadoop file system deletes completely

Embodiment Construction

[0032] The present invention will be further described below in conjunction with accompanying drawing:

[0033] Such as figure 1 As shown, the present invention includes a user client, a Hadoop name node and a data node. The Hadoop name node responds to the service request of the user client and forwards it to the service program in the data node after processing.

[0034] a. The client selects the file name and deletion level to be completely deleted, and sends a service request to the Hadoop name node.

[0035] b. After the name node of Hadoop receives the service request sent by the user client, it locks the task list for exclusive access. If the task list is queried and the deletion service request sent by the user client is not in the task list, the task is added to the task list list, and then release the task list lock, if the request for deleting the service sent by the query user client is already in the task list, feedback to the user client that the task is already...

Abstract

The invention discloses a method for complete deletion of concurrent high-speed data in a Hadoop file system, realizes complete deletion of data in the Hadoop file system, quickly and effectively clears data, ensures user data security, effectively prevents data leakage, and avoids Hazards and economic losses caused by leakage.

Description

technical field [0001] The invention relates to the field of data security, in particular to a method for completely deleting concurrent high-speed data in a Hadoop file system. Background technique [0002] Data security is the main problem faced by cloud computing, so the research on data security has become one of the key research directions of cloud computing. As a data processing platform widely used in cloud computing, Hadoop does not provide effective protection for data confidentiality during operation, especially for deleted data, and does not provide a safe and effective data deletion mechanism. Data breaches are likely to occur due to: [0003] 1) If a DataNode fails, the stored data in the DataNode cannot be completely protected, which will lead to security issues of data leakage. [0004] 2) Due to the recycle bin mechanism of the Hadoop file system, the files deleted by the user are not completely deleted, but moved to the recycle bin folder. Therefore, file...
