A cloud computing data security mark management method and system

Abstract

The present invention proposes a cloud computing data security label management method and system, which relate to the field of cloud computing and data security. The method sets the format of the cloud data security label, generates a new cloud data security label, and stores the new cloud data security label respectively store in the client database and the server database; when the client starts, the client tag data including the new cloud data security tag is loaded into the memory, and the tag data is processed during the operation of the client Update in real time, and at the same time update the server tag data including the new cloud data security tag in the database of the server. The invention defines the format composition of cloud data security tags, analyzes the tag data types involved in the application and management of cloud computing data security tags, and provides a distributed storage scheme; designs three response methods to efficiently process tag data Create, retrieve, modify, and delete operations to reduce the impact on client execution efficiency.

Description

technical field [0001] The invention relates to the field of cloud computing and data security, in particular to a cloud computing data security label management method and system. Background technique [0002] Cloud computing represents an important trend in the development of scale, specialization and intensification in the IT field. The security of cloud computing has received more and more attention, and has become an important factor restricting the development of cloud computing technology and industry. Cloud computing security faces many challenges. Among them, data security is due to its basic position in practical applications. , has become the primary problem that needs to be broken through and solved most urgently. [0003] The root of cloud computing data security problems lies in the separation of data ownership and control rights. The service model of cloud computing is that users hand over data to cloud service providers for storage or entrust them to run cer...

Problems solved by technology

[0003] The root of cloud computing data security problems lies in the separation of data ownership and control rights. The service model of cloud computing is that users hand over data to cloud service providers for storage or entrust them to run certain applications, and users lose control over their data. In this service mode, malicious cloud services can directly steal users' private data without being discovered by users; untrustworthy components in the cloud platform, hackers, Trojan horses and other malicious software can illegally read, leak or tamper with users' sensitive data; Malicious behaviors such as virtual machine escape will lead to unauthorized use of user data between virtual machines. Due to the lack of strong security control technology support, users cannot ensure that their data is used correctly in the cloud platform
