China's Personal Information Protection Law has determined citizens' right to carry their personal information through empowerment. However, due to issues such as ambiguous objects, missing paths, and technical obstacles, this right is difficult to be implemented. At the attribute level, the right of portability is a kind of "data dominance right", aiming to transfer the control of personal information from the platform to the user. It has dual attributes of personality rights and property rights and is reflected as a necessary supplement to the insufficiency of private law by public law. In terms of the object, the scope of the object should be reshaped with an "inclusive" approach: Unless the platform can prove that the transfer infringes upon its trade secrets or legitimate interests, all data within the user account should be allowed to be transferred, and the data of a single account does not constitute a trade secret. In terms of implementation, through the application of blockchain technology, not only can the security issues during the transfer of personal information be resolved, but also the transfer costs can be reduced.
