Abstract
This study focuses on the key technologies and strategies for data privacy protection in the cloud computing environment. Summarizing the definition, characteristics and main service mode of cloud computing technology, it provides a basis for understanding the data flow and storage in the cloud computing environment. To explore the basic concept of data privacy protection, it emphasizes the definition of data privacy and its importance in modern society. Analyze the key technologies of data privacy protection in the cloud computing environment, including data encryption technology, access control technology, data desensitization technology and privacy protection algorithm. These technologies constitute the core line of defense for data privacy protection, and are crucial to ensure data security and privacy. It reveals the problems existing in the data privacy protection technology in the current cloud computing environment. Poor access control, insufficient data encryption, weak regulatory compliance, and improper data lifecycle management all pose a serious threat to data privacy. In particular, the problems such as weak identity authentication, improper authority management, backward encryption technology, improper key management, insufficient compliance with regulations, and incomplete data deletion need to be solved urgently. To meet these challenges, strategies for data privacy protection in the cloud computing environment are proposed. Strengthening access control, data encryption, regulatory compliance, and data lifecycle management are designed to build a more secure and compliant data privacy protection system. Specifically, the level of data privacy protection will be comprehensively improved by enhancing identity authentication, strict authority management, updating encryption technology, optimizing key management, complying with regulatory requirements and implementing compliance audit.
