Fig. 1 shows a system architecture diagram of a case collaborative processing system according to an embodiment of the present application, which is detailed as follows: for convenience of explanation, only portions related to the embodiments of the present application are shown.
Refer to fig. 1. The case collaborative processing system comprises: the system comprises an initiator 1, a collaborator 2, a block chain server 3 and a distributed server 4, wherein the initiator 1 and the collaborator 2 are electronic devices and can communicate with the block chain server 3 and the distributed server 4. Wherein:
the initiator 1 is used to send a case co-investigation request to the blockchain server 3.
And the block chain server 3 is used for carrying out full link synchronization on the collaborative search request and determining the collaborative search party 2 corresponding to the case according to the collaborative search request.
In some embodiments, the above-mentioned collaborator request includes a specified identity of the collaborator 2, and the blockchain server 3 may determine the collaborator 2 corresponding to the collaborator request according to the identity of the collaborator 2.
The collaborating party 2 is configured to obtain the collaborative query request synchronized by the blockchain server 3, obtain first collaborating information and second collaborating information based on the collaborative query request, send the first collaborating information to the initiating party 1 through the distributed server 4, and upload the second collaborating information to the blockchain server 3, where the second collaborating information corresponds to the first collaborating information.
The initiator 1 is further configured to receive the first collaborative information fed back by the collaborator 2 through the distributed server 4, and obtain the second collaborative information through the blockchain server 3.
The above-mentioned blockchain server 3 is used for cross-region investigation and collaboration. Law enforcement agencies, including the relevant departments, are communicatively connected to the blockchain server 3. In this embodiment, the initiator 1 is a party initiating a collaborative search request among a plurality of parties connected to the blockchain server 3. The collaborator 2 is one of the parties connected to the blockchain server 3, and the blockchain server 3 collaborates on the case determined by the collaborating request. Wherein there may be more than one of the collaborators 2.
In the embodiment of the application, a sender sends a case collaborating request to a blockchain server, determines a collaborator corresponding to a case through the block chain server full-link synchronous case collaborating request and according to the collaborating request, the collaborator directly sends first collaborating information obtained through collaborating to an initiator through a distributed server, meanwhile, uploads second collaborating information corresponding to the first collaborating information to the blockchain server, and the initiator can determine a case collaborating processing result according to the first collaborating information and the second collaborating information. According to the method and the system, cross-region cooperative inspection of the initiator and the cooperative inspection party is realized by using the distributed server, the case cooperative inspection efficiency can be improved, and meanwhile, the block chain server is used for storing the initiation of the cooperative inspection request and the cooperative inspection result, so that the authenticity of the cooperative case information is effectively guaranteed, the case information is prevented from being tampered, and the safety of the cooperative inspection case information is improved.
As a possible implementation manner of the present application, the case collaborative search processing system may use a WIFI technology or a 3G/4G/5G technology to establish communication connections between the blockchain server 3 and the initiator 1 and the collaborator 2, or may use a serial port technology to establish wired connections between the blockchain server 3 and the initiator 1 and the collaborator 2. The initiator 1 and the collaborator 2 are both in communication connection with the distributed server 4 through the network.
Fig. 2 shows an implementation flow of the case collaborative processing method provided by the embodiment of the present application, an execution subject of the flow is the initiator shown in fig. 1, and the flow of the method includes steps S101 to S104. The specific realization principle of each step is as follows:
s101: and sending a case collaborating request to a block chain server, wherein the collaborating request is used for indicating the block chain server to carry out full link synchronization on the collaborating request, and determining a collaborating party corresponding to the case according to the collaborating request.
When a case needs to be collaborated, the initiator sends a collaborative query request of the case to the blockchain server, and the blockchain server performs full-link synchronization on the collaborative query request to any other node in communication connection with the blockchain server by using a consensus algorithm.
The block chain server can be used for storing trusted data and storing collaborative information in a cross-region case collaborative process.
In some possible embodiments, the functions of the blockchain server specifically include, but are not limited to: trusted storage, metadata storage, collaborative record management, cross-domain data sharing, data reporting, data tampering monitoring, data sharing authority management, directory management, private data collaborative model management, case management, summary management, and case collaborative process supervision.
As a possible implementation manner of the present application, the above-mentioned collaboration request carries a case type of the case, and fig. 3 shows a specific implementation flow of performing full link synchronization on the collaboration request by a block chain server in the case collaboration method provided in the embodiment of the present application, which is detailed as follows:
a1: and the block chain server calls an intelligent contract corresponding to the case type, and performs full link synchronization on the collaborative query according to the processing logic of the intelligent contract. The case types include normal and sensitive.
The block chain server triggers the running of the intelligent contracts when receiving the collaborating request sent by the initiator, and in this embodiment, the block chain server deploys at least two sets of intelligent contracts, and the triggered running intelligent contracts are different according to different case types.
A2: if the case type is common, the block chain server calls a first intelligent contract, and the collaborating request is subjected to full-link synchronization according to the processing logic of the first intelligent contract.
In this embodiment, for a case of a common type, case information carried in a collaborative query of an initiator is not confidential, a first intelligent contract is called by a blockchain server, full-link synchronization is performed on the collaborative query according to processing logic of the first intelligent contract, and after receiving the collaborative query of the full-link synchronization of the blockchain server, any node on a link can acquire the case information, thereby ensuring that the collaborative query and the case information thereof are transparent.
A3: and if the case type is sensitive, the block chain server calls a second intelligent contract, and the full link synchronization is carried out after the cooperation request is processed through privacy calculation according to the processing logic of the second intelligent contract. The second intelligent contract is different from the processing logic of the first intelligent contract, and the second intelligent contract comprises processing logic for carrying out privacy calculation on case information in the collaborative search request.
The privacy calculation refers to a technical set for realizing data analysis calculation on the premise of protecting data from being leaked to the outside. Compared with the traditional data use mode, the encryption mechanism of the privacy calculation can enhance the protection of data and reduce the data leakage risk. In this embodiment, the specific algorithm of the privacy computation adopted in the blockchain server may refer to the prior art, which is not described herein again.
In this embodiment, for a sensitive case, case information carried in a collaborating request of an initiator needs to be kept secret, a blockchain server invokes a second intelligent contract, according to processing logic of the second intelligent contract, the collaborating request is subjected to privacy computation and then subjected to full link synchronization, after receiving the collaborating request for the full link synchronization of the blockchain server, any node on a link performs privacy computation, so that the collaborating party cannot specifically obtain the case information and only knows that the initiator initiates the collaborating request, and the privacy of the information is effectively guaranteed while the disclosure and transparency of the collaborating request are guaranteed.
In the embodiment of the application, the block chain server calls different intelligent contracts for processing cases of different case types, so that traceability of a case collaborative check process can be guaranteed, and information safety of the cases can be guaranteed.
In order to avoid misuse of the collaborative investigation and comply with the policy related to the cross-regional collaborative investigation, for the case of the cross-regional collaborative investigation, generally, a collaborative investigation request is initiated on the blockchain server and successfully received and processed by the collaborators, and needs to have a certain qualification, for example, the related departments can directly initiate the collaborative investigation request, and the collaborative investigation request initiated by the law enforcement agencies in various places needs to be approved by the related departments.
As a possible implementation manner of the present application, the collaborative query request carries an identity of the initiator, and fig. 4 shows a specific implementation flow of determining, by a blockchain server, a collaborative query party corresponding to a case in the case collaborative query method provided in the embodiment of the present application, which is detailed as follows:
b1: and the block chain server determines whether the initiator has the right of directly initiating the collaborative check request according to the identity of the initiator.
The identity may be used to identify the corresponding identity of the originating party, e.g., the identity of a local law enforcement agency or a related department. And determining whether the initiator has the right to directly initiate the collaborative query according to the identity corresponding to the identity identifier.
B2: and if the initiator has the right of directly initiating the collaborating request, the block chain server determines the collaborating party corresponding to the case according to the collaborating request.
In this embodiment, when the corresponding identity of the initiator is the relevant department, it may be determined that the initiator has the right to directly initiate the collaborative query request. When the initiator is a local law enforcement agency, the initiator is determined not to have the right to directly initiate the collaborative investigation request.
As a possible implementation manner of the present application, as shown in fig. 4, the determining, by the blockchain server, a specific implementation flow of a collaborator corresponding to the case further includes:
b3: and if the initiator does not have the right of directly initiating the collaborative check request, the block chain server detects an approval result fed back by the auditor based on the collaborative check request, and performs full-link synchronization on the approval result.
The auditor is an electronic device accessing the blockchain server. The auditor specifically corresponds to a user having an audit right, for example, a related department. When the initiator does not have the right of directly initiating the co-check request, the auditing party locally examines and approves the co-check request after receiving the co-check request of the block chain server full link synchronization, and sends an examination and approval result to the block chain server, and the block chain server detects the examination and approval result fed back by the auditing party based on the co-check request and carries out full link synchronization on the examination and approval result. Other nodes in the chain can obtain the examination and approval result of the collaborative search request.
B4: and if the examination and approval result is detected to be passed, the block chain server determines a co-investigation party corresponding to the case according to the co-investigation request.
