Abstract

The invention discloses a data sharing method, which is applied to a data sharing system, and comprises the following steps of: firstly, setting a data end as a certificate issuing end, and respectively deploying the certificate issuing end and a data dependence end in a certificate center subsystem and an open certificate service subsystem; direct data connection between a certificate issuing end and a data dependence end can be effectively avoided, and then the safety problem possibly caused by direct data connection can be avoided; in addition, data of a data party can be subjected to credential transformation, so that a data sharing and using process is converted into a request and verification process of an encrypted credential; and the machine-readable and verifiable encryption certificate can effectively solve the security and privacy protection problems in the current data circulation and use process, and can prevent the data from being copied and then circulated, thereby facilitating the promotion of data opening and sharing. The invention also provides a data sharing system and a computer readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The present invention relates to the field of data sharing, in particular to a data sharing method, system and computer-readable storage medium. Background technique [0002] The main way of data sharing today is the direct sharing of metadata, which requires the data relying party to establish an offline trust relationship with the data party, and build a shared secret (such as password or cryptographic credential information) associated with the sharing agreement; at the same time , it is necessary to establish an information channel between the two information systems, and submit the pre-agreed and recorded credential information during the online access process to obtain access authorization; in addition, the shared data is encrypted and transmitted based on the key negotiated by both parties to avoid the transmission process security risks in. However, the trust relationship between the data relying party and the data party and the encryption cer...
