Abstract: With the highquality development of the digital economy,  people are increasingly closely connected with internet platforms. In the era of continuous emergence of various data, as the basic element and core driving force of digital economy, the flow of data not only affects personal data security, but also has a significant impact on national security. As an important carrier of data processing, the internet platform should undertake the obligation of data security. Since the DiDi Cyber security review case, the data security governance of the platform is still facing many practical difficulties, and the security risk caused by the crossborder flow of data is an important problem. Therefore, China continues to improve the legal system of data security, and to strengthen the governance of platform data security. Under the current governance situation, it is necessary to optimize the governance road of platform data security, resolve major national security risks, and then master more international right of speech in global data governance.
