The system comprises a data request end, a client end, a data transfer end and a data holding end, wherein an encryption and decryption unit is arranged on a node corresponding to the data request end, the client end, the data transfer end and the data holding end, a private key is deployed, and an intelligent contract is deployed on a blockchain network.
In the embodiment of the invention, the data request end is a node needing data, the data holding end is a node holding the data of the client, the client is a node to which the data belongs, the data transfer end is in communication connection with a plurality of clients, and the data transfer end is a node for transferring the information sent by the data request end to the corresponding client.
In the embodiment of the present invention, the encryption and decryption algorithm adopted by the encryption and decryption unit may be one or more of the following encryption and decryption algorithms: DES (Data Encryption Standard) data encryption standard algorithm, symmetric encryption AES, asymmetric encryption ECC, message digest MD5, or digital signature DSA. Preferably, the encryption and decryption algorithm used may be asymmetric encryption.
Further, as shown in fig. 1, the method may include the steps of:
s100, a data request end sends first request information to a data transfer end, wherein the first request information at least comprises an ID of the data request end, an ID of a requested object and first request data.
The ID of the data request end and the ID of the requested object may be set based on actual needs, as long as the identities of the data request end and the requested object can be uniquely determined.
In embodiments of the present invention, the requested object may be a person. The first request data may be data generated by the requested object. In one exemplary embodiment, the first request data may be medical data, although other data is also possible. Those skilled in the art will appreciate that the medical data may be all medical data generated in a hospital, including, for example, historic diagnosis of disease types, number of times of diagnosis and treatment of the same disease, medical attending doctors, and medical hospitals, etc., and may specifically be electronic medical records, diagnosis and treatment schemes, medical records, examination result data, medical consumption, and costs, etc.
Further, in the case where the requested data is medical data, the data requesting end may be a doctor and a third party institution such as medical research, pharmaceutical clinical trials, medical insurance claims, and the like. In the case that the data request end is a doctor, the first request information further includes a direction of indication of the doctor.
And S200, the data transfer terminal compares the received first request data with the data corresponding to the ID of the requested object, if the data corresponding to the ID of the requested object comprises the first request data, the first request information is sent to the terminal corresponding to the ID of the requested object, otherwise, the first request information is not sent to the client corresponding to the ID of the requested object, for example, if the first request data is medical data, if the data requested by the data request terminal is tuberculosis medical data and the associated data of the requested object does not comprise tuberculosis medical data, the first request information is not sent to the client corresponding to the ID of the requested object.
In the embodiment of the present invention, the data transfer terminal may be any existing server terminal with data transfer capability.
The technical effect of S200 is that, since whether the data type corresponding to the ID of the requested object includes the first request data is used as the filtering condition, the influence of a large number of unmatched requests on the requested object can be avoided.
S300, in response to receiving the first request information, the client corresponding to the ID of the requested object determines whether to send authorization information.
In the embodiment of the invention, after receiving the first request information, the requested object determines whether to agree to send the corresponding data to the data request terminal based on the first request information, if so, sends the authorization information including the public key of the request terminal, the public key of the data request terminal, the data use permission time range and the like through the blockchain, and records the authorization information into the blockchain through the intelligent contract.
In the embodiment of the invention, the requested object can determine whether to send the authorization information according to the ID of the data request end and the requested data type, so that the private data of the requested object can be prevented from being revealed.
And S400, in response to receiving the authorization information, the data holding end sends the data corresponding to the first request data to the data request end.
After the data holding end obtains the authorization information through the chain, the public key of the requested object is mapped into the ID of the requested object, then the corresponding query service is started to obtain the data corresponding to the requested data type, and then the obtained data address and the symmetric key are encrypted by using the public key of the data requesting end and uploaded to the blockchain.
When the data request end receives the authorization information on the chain, the data request end decrypts the authorization information through the private key of the data request end, obtains the data through the corresponding data channel and decrypts the data to obtain the required data.
According to the information interaction method provided by the embodiment of the invention, the interested data is stored in the production source end instead of being uniformly transmitted to the central end, so that the risk that the interested data is easy to attack and tamper can be avoided, and the credibility of the interested data is high.
