International Law Protection of Cross-Border Transfers of Personal Information Based on Cloud Computing and Big Data

Abstract

Cross-border data is crucial for the digital economys growth, but uncontrolled transfers risk national security, public interests,
corporate interests, and data sovereignty. Currently, cross-border data regulation lacks unified global rules, with existing ones dominated by
Europe and the U.S. China needs to improve its international legal protection for cross-border personal information transfer. This paper examines Chinas mechanisms for personal data privacy protection in digital trade, including frameworks for big data, cloud computing, and cloud
service selection for data lifecycle privacy protection. It suggests clarifying data controllers and exporters obligations, strengthening regulatory responsibilities, improving cross-border data legislation, enhancing law operability, and advocating for stronger international cooperation
and participation in global rule-making to protect personal privacy information rights.
