Embodiments of the present invention provide a personal information authorization method, an authentication center, and a service provider. Wherein, the method includes: after receiving the transaction filing package sent by the user side, the authentication center generates a symmetric key and sends it to the user side, so that the user side encrypts the data to be sent according to the symmetric key, Generate encrypted data and send it to the service provider for the service provider to generate a transaction record package and submit it to the blockchain after receiving the encrypted data; the authentication center obtains the transaction from the blockchain record package, if it is determined that the content of the transaction record package is consistent with the transaction record package, then send the symmetric key to the service provider, so that the service provider can The encrypted data is obtained to obtain the personal information of the user. It improves the user's personal information security and enables the user to understand the flow and use of personal information.
Description
technical field [0001] The invention relates to the technical field of information security, in particular to a personal information authorization method, an authentication center and a service provider. Background technique [0002] With the advent of the information age, more and more digital services provide convenience for people's lives, but also make personal information leakage more and more serious, resulting in the occurrence of personal information leakage incidents such as spam text messages and harassing calls. [0003] Once the personal information is authorized by the user to the service provider, the user has no way of knowing how the personal information will be used, and cannot grasp the degree of diffusion and leakage of the personal information, which makes it difficult for the user to provide evidence to protect rights after encountering a personal information leakage incident. [0004] In the existing technology, personal information can be protected thr...
