摘要： Embodiments of the present specification disclose a trusted hardware-based data management method, apparatus, and device. The solutions include the following: a data owner can register a personal decentralized identifier based on a blockchain technology, and establish a binding relationship between the decentralized identifier of the data owner and trusted hardware, so that after obtaining data description information used to describe target data of the data owner that can be provided by a trusted institution, the trusted hardware can request the trusted institution to verify whether the trusted institution stores user service data needed for generating the target data. If the trusted institution stores the user service data needed for generating the target data, the data owner can publish the data description information by using the trusted hardware, so that the data owner can conveniently manage a data asset by using the trusted hardware.
