Description
Technical Field
The invention belongs to the technical field of block chains, and particularly relates to a method and a device for calling user data of an information sharing system based on an Ethernet block chain.
Background
An etherhouse (Ethereum) system is an open-source public blockchain platform with an intelligent contract function, compared with a common blockchain system, the common blockchain focuses on recording of pure information, and the etherhouse is essentially a programming language running on the blockchain and helps developers to build and release required distributed application programs. The intelligent contract related to the system is a distributed application program running on the block chain system, and the contract completes the executed program. The etherhouse blockchain not only manages and tracks transactions like the bitcoin blockchain, but it can also be programmed by programming logic that stores and executes new code.
In the prior art, each different organization or unit stores the collected and edited information of the organization or unit, on one hand, in order to facilitate the data sharing of each organization or unit, the stored information is disclosed to the external network, i.e. not physically isolated from the external public network, but in this way, although the information sharing is facilitated, the security problem that the information is randomly accessed and tampered exists; on the other hand, in order to prevent security problems such as network attacks, each organization or entity may store such information in its own network physically isolated from the outside public network. However, while this avoids security issues, information sharing between various organizations or units is inconvenient. Taking a hospital (i.e., a regional medical complex) as an example, the hospital integrates medical resources in the same region, and generally comprises a third-level hospital, a second-level hospital, a community hospital and a village hospital in one region. In order to realize the grading diagnosis and treatment, the mutual recognition of diagnosis results and prescriptions is realized in the medical unit. However, the current diagnosis mutual-confirmation and prescription mutual-confirmation results are commonly shared in such a way that a patient carries a prescription of a superior hospital to a subordinate medical institution to purchase a medicine, and the inquiry information sharing is performed through a paper diagnosis document or a medical record of the superior medical institution.
Therefore, the data sharing scheme in the prior art is difficult to unify safety and convenience. Therefore, a secure and convenient data sharing scheme is required.
