Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments. The present invention is not limited to the embodiment, and other embodiments may be included in the scope of the present invention as long as the gist of the present invention is satisfied.
In the preferred embodiment of the present invention, based on the above problems in the prior art, there is now provided a blockchain-based ultrasound data management system, as shown in fig. 1 and 2, which specifically includes:
the system comprises a plurality of user sides 1 and a cloud storage server 2 connected with each user side 1, wherein each user side 1 comprises a data storage module 11, and the data storage modules 11 of all the user sides 1 are connected with each other to form a block chain network 3;
each user terminal 1 further comprises:
the data processing module 12 is used for the user to upload the ultrasonic data file obtained by ultrasonic scanning, and process the ultrasonic data file to obtain an ultrasonic identity code and an encryption check code associated with the ultrasonic data file;
the data transmission module 13 is respectively connected with the data storage module 11 and the data processing module 12, and is used for uploading the ultrasonic data file and the ultrasonic identity code associated with the ultrasonic data file to the cloud storage server 2 for storage, and sending the ultrasonic identity code and the encrypted check code associated with the ultrasonic data file to the block chain network 3 for distributed storage;
and the data management module 14 is connected to the data storage module 11, and is configured to access the blockchain network 3 according to an external data management request, and perform data management on the ultrasound data file stored in the cloud storage server 2 according to the ultrasound identity code and the encryption check code stored in the blockchain network.
Specifically, in this embodiment, the user side 1 of the present invention is preferably an SDK user layer, and is configured to manage ultrasound data files, take charge of service logic interaction, provide a function of uploading ultrasound data files and related information, and provide a query function for a user. The SDK user layer preferably has two application modes, the first mode is directly deployed to a PC or a mobile terminal as an application program mode, and the second mode is used for providing third-party application in an SDK packaging mode and is combined with the ultrasonic data management system of the invention for use. The format of the ultrasound data file is preferably DICOM format. The block chain network 3 of the invention uses a block chain protocol, the ultrasonic data file is not stored on the block chain network 3, and only the unique ultrasonic identity code of the ultrasonic data file in the cloud storage server 2 and the encryption of the ultrasonic data file are stored to obtain the encrypted check code. The cloud storage server 2 is used for storing the ultrasonic data file and the unique ultrasonic identity code associated with the ultrasonic data file.
As a preferred embodiment, before performing data management on the ultrasound data file, the user terminal 1 preferably enters a corresponding user name and a login password through a login interface for a doctor to log in, and more preferably, the user terminal 1 further generates a user public key for accessing the blockchain network 3 according to the user name, the login password and other associated login information, and further preferably, by using hardware information. The blockchain network 3 includes a plurality of blockchain nodes, and each blockchain node corresponds to the data storage module 11 of each user terminal 1. When receiving an ultrasonic data file to be stored, a user side 1 firstly performs identity coding on the ultrasonic data file to obtain a unique ultrasonic identity code corresponding to each ultrasonic data file, and simultaneously performs encryption processing on the ultrasonic data file to obtain an encryption check code corresponding to an encryption algorithm, and then stores the ultrasonic identity code and the encryption check code to a block chain network 3, and simultaneously, centrally stores the ultrasonic identity code and the ultrasonic data file to a cloud storage server 2. Each ultrasound data file has a unique ultrasound identity code, which remains unchanged even if the ultrasound data file is modified.
Further specifically, when the ultrasonic data file needs to be searched, the blockchain network 3 is accessed according to the public key of the user to confirm that the operator has corresponding operation authority, meanwhile, the encrypted check code associated with the ultrasonic identity code is obtained from the blockchain network 3 through the ultrasonic identity code of the ultrasonic data file needing to be searched, then the ultrasonic data file corresponding to the ultrasonic identity code is obtained from the cloud storage server 2 according to the ultrasonic identity code, then the ultrasonic data file is encrypted to obtain the real-time check code of the ultrasonic data file, and the information whether the ultrasonic data file is modified or not can be obtained by matching the originally stored encrypted check code with the real-time check code. That is, if the originally stored encrypted check code matches the real-time check code, it indicates that the ultrasound data file has not been modified, and the ultrasound data file is valid data, and at this time, the ultrasound data file is output to the user terminal 1 for the user of the user terminal 1 to view. If the originally stored encrypted check code is not matched with the real-time check code, the ultrasonic data file is modified to be invalid data, and a data invalidity prompt is given for the user of the user end 1 to check.
Further, when the ultrasound data file needs to be modified, the ultrasound identity code of the ultrasound data modification file that needs to be modified is known, the ultrasound data modification file is preferably encrypted again to obtain the modification check code corresponding to the ultrasound data modification file, and unlike the newly added data, the ultrasound data modification file is preferably subjected to data verification first to determine whether to update the data of the cloud storage server 2. The verification preferably matches the modification check code with the encrypted check code stored in the block chain network 3, and the modification check code matches the encrypted check code, so that data updating is not required for the cloud storage server 2, and only the modification record of this time, that is, the modification check code and the corresponding ultrasonic identity code, are stored to the block chain network 3 as a piece of newly added information. If the modified check code is not matched with the check code, the modified check code and the corresponding ultrasonic identity code are required to be stored to the block chain network 3 as a piece of new information, and meanwhile, the ultrasonic data modification file is adopted to cover the ultrasonic data file which is previously stored in the cloud storage server 2, so that the cloud storage server 2 is updated.
