The authenticity and the integrity of the data information in the distribution interaction process are ensured through the method, but in the cloud side architecture, due to the heterogeneous environment among the three, the privacy of the data information needs to be used as an important factor for strengthening mutual trust of the three during data information interaction.
In one embodiment, the method further comprises the following steps: uploading data to be distributed to a storage space by an uploading node, linking a storage certificate to a block chain network, and writing an access authority rule into an intelligent contract; setting access authority according to an RBAC mechanism in the intelligent contract, and refining access control to data items; when downloading data information, downloading a node, firstly calling an intelligent contract checking authority, and returning an item which can be accessed by the node and a corresponding storage address by the intelligent contract; and downloading the corresponding data items by the downloading node, and linking the downloading result. Wherein, RBAC mechanism is Role-Based Access Control mechanism. The rule of the access authority is written into the intelligent contract through the uploading node, wherein the access rule is that the downloading node needs a unique and corresponding downloading token to correspond to the intelligent contract, and the access authority can be obtained through the intelligent contract identification, so that the data information has privacy protection when cross-chain interaction is carried out. By introducing the RBAC mechanism, in the RBAC model, the authority is associated with the role, different roles have different authorities, and after the user obtains the authority users of different roles by being distributed to different roles and is associated with the role, the user can carry out autonomous authorization and authority specialization at the same time, and authorization information must be controlled through the roles to realize access control, so that the privacy protection is controllable and adjustable, and is very flexible.
By the method, the integrity, authenticity and privacy of the data information during distribution interaction are guaranteed, and a reliable and safe foundation is laid for the application of the data certificate structure in the block chain network framework.
