Abstract: With the continuous development of technology and law, data subjects have increased the possibility of using conflicting methods to protect their data rights under the joint promotion of the two. The right to data portability has been revised several times as an independent right and was stipulated in the General Data Protection Regulation (GDPR) passed in 2016. The right to data portability enhances the data subject's control over personal data and at the same time gives the data controller more responsibilities, which has aroused great controversy in academia. Behind the various disputes are the very different attitudes and goals of the game's main players, network users, network platforms, and countries towards the right to data portability. Regarding the scope of data portability, the reasonable protection of the rights of third-party data subjects, and whether the original data controller can retain the personal data related to the data subject, there are loopholes. The personal data is divided into user basic data and derivative data. The "portability" of the two uses different system designs, trying to find a suitable balance between the rights of the data subject and the interests of the data controller.
