step two: the system comprises a block chain network formed by a plurality of authority proving nodes and a main node, wherein when the block chain network broadcasts, a management system receives and reads a judicial case data information query instruction sent by the main node, and after receiving the broadcast of the block chain network, the system sends encrypted data of the judicial case to the main node;
step three: after receiving the encrypted data, the master node sends a judicial case data information query instruction, and the master node acquires user information in the query instruction, and then extracts corresponding data information from the blockchain network according to the user information and decrypts the data information;
step four: when decrypting the encrypted data, the system receives an information inquiry instruction of the master node for sending the judicial case encrypted data, acquires user information, extracts the encrypted data corresponding to the judicial case according to the user information in the blockchain network, determines information consistent with the MD5 check code in the read judicial case encrypted data, and sends the consistent information to the master node;
step five: after the judicial case data information is sent to a main node for reading and relevant work management, new judicial case data is generated, and the newly generated judicial case data is checked and a data fingerprint of an original file of the judicial case data is generated;
step six: and transmitting the storage address of the original file of the judicial case data, the user information corresponding to the original file and the data fingerprint generated by the original file to a blockchain network formed by a plurality of authoritative proving nodes, broadcasting the blockchain network at all nodes of the whole network, and updating the storage content in all the authoritative proving nodes.
And in the fourth step, when the encrypted data is decrypted, the slave node is specifically used for decrypting the extracted judicial case encrypted data by using a pre-stored secret key to obtain decrypted judicial case data information, a new MD5 verification code is generated through an MD5 algorithm and the decrypted data information, the new MD5 verification code is verified with all MD5 verification codes in the blockchain, and judicial case data information with consistent verification is sent to the master node.
Compared with the prior art, the invention has the following beneficial effects: the invention effectively and safely manages the judicial case data based on the blockchain management system, establishes the intensive data application service through the encryption technology of the judicial auxiliary case data, exerts the deep value of notarization management work, can realize the construction of informationized infrastructure of the judicial data resource library in the process, replaces the traditional case-handling data management mode, and effectively improves the efficiency and the safety of information acquisition related to case handling.
Drawings
The invention is further described below with reference to the accompanying drawings:
FIG. 1 is a flow chart of steps of a method for managing judicial case data based on blockchain technique according to the present invention.
Detailed Description
As shown in fig. 1, the present invention provides a judicial case data management method based on a blockchain technology, which mainly includes receiving and reading judicial case data information query instructions sent by a master node after broadcasting a blockchain network composed of a plurality of authoritative certification nodes, receiving judicial case encrypted data after broadcasting the blockchain network, and sending the judicial case encrypted data to the master node;
the judicial auxiliary case management system comprises a master node and a plurality of slave nodes, wherein the master node is respectively connected with the plurality of slave nodes, and each slave node corresponds to an authority proving mechanism.
After receiving broadcast of a blockchain network formed by a plurality of authority proving nodes and receiving read judicial case encrypted data, the receiving main node sends a judicial case data information inquiry instruction, user information is obtained in the inquiry instruction, and corresponding data information is extracted and decrypted in the blockchain network according to the user information.
The decryption method specifically comprises the steps of determining information consistent with MD5 check codes generated by case files in reading judicial case data encryption information, and sending the information to a master node; decrypting the extracted judicial case encrypted data information by using a pre-stored key to obtain decrypted judicial case data information, generating a new MD5 verification code by an MD5 algorithm and the decrypted data information, checking the new MD5 verification code with all MD5 verification codes in the block chain, and transmitting judicial case data information with the same check to the main node.
Receiving a judicial case encryption data information query instruction sent by the master node, acquiring user information, extracting corresponding judicial case encryption data information from the blockchain network according to the user information, determining information consistent with the MD5 check code from the read judicial case encryption data information, and sending the information to the master node.
The slave node is specifically configured to decrypt a key pre-stored in the extracted judicial case data information, so as to obtain decrypted data information; generating a new MD5 verification code by an MD5 algorithm and decrypted data information; and checking the new MD5 verification code and all MD5 verification codes in the block chain, and sending data information consistent with the MD5 verification codes to the master node.
And after the judicial case data information is sent to a master node for reading and relevant work management, new judicial case data is generated, and the newly generated judicial case data is checked and a data fingerprint of the judicial case data original file is generated.
And transmitting the storage address of the judicial case data original file, the corresponding user information and the generated data fingerprint thereof to a blockchain network formed by a plurality of authoritative proving nodes, broadcasting the blockchain network at all nodes of the whole network, and updating the storage content in the authoritative proving nodes.
