103. And acquiring case ratio data corresponding to the query information from the block chain through the block chain basic service platform, and sending the case ratio data to the case ratio data service platform, wherein the case ratio data comprise case ratio data uploaded to the block chain by a plurality of different law enforcement agencies.

The blockchain may be a federation chain, such as a federation chain cooperatively maintained by a number of law enforcement agencies (e.g., police, inspection yards, and courts).

For example, the block chain basic service platform may specifically receive the data acquisition request, acquire case ratio data corresponding to the query information from the block chain, and send the case ratio data to the case ratio data service platform.

Optionally, case ratio data corresponding to the query information is acquired from the block chain through the block chain basic service platform, and the case ratio data is stored in the database so that the case ratio data service platform performs statistical analysis on the data in the database.

The embodiment of the present application will be described from the perspective of a case ratio query device based on a block chain, where the device may be integrated in any node of the block chain, and the node may be a single device or a device cluster.

Where the blockchain may be a federation chain (i.e., a federation blockchain), such as one that may be cooperatively maintained by a plurality of different law enforcement agencies, the federation chain constructed by the devices of the plurality of different law enforcement agencies on a contract basis. The nodes in the alliance chain can be single equipment of a law enforcement agency or equipment clusters. The case ratio query device based on the block chain can be integrated in any node in the alliance chain.

The case ratio query method based on the blockchain provided by the embodiment of the application can be executed by a processor of a first node in the blockchain, for example, the first node can be any node in the blockchain; as shown in fig. 6, the specific flow of the case ratio query method based on the blockchain may be as follows:

201. and acquiring a storage request, wherein the storage request carries case ratio data to be stored, and the case ratio data to be stored comprises case ratio data of different law enforcement agencies.

The case ratio data to be stored can be case information generated in the case processing process of different law enforcement agencies or record information of litigation links.

For example, the case ratio information may be a storage request sent by a receiving terminal (the terminal is a terminal corresponding to the first node), where the storage request carries the ratio data that needs to be stored in the block chain by the law enforcement agency and the terminal system time when the case ratio data is uploaded, and a timestamp is added to the case ratio information according to the terminal system time, for example, the terminal time may be directly used as the timestamp.

The information processing method comprises the steps that a timestamp server of a third party can be added for case ratio data, a terminal sends a storage request to the timestamp server, the timestamp server can add a timestamp to case ratio information according to terminal system time, and the storage request is sent to a first node after the timestamp server adds the timestamp to the case ratio data.

202. And carrying out hash operation and digital signature on case ratio data to be stored to obtain encrypted data.

Among them, a hash algorithm (hash) can generate a code called a message digest by using a text, and maps a binary system of an arbitrary length to a binary value of a short fixed length, and the hash algorithm includes MD4, MD5, SHS, and the like.

The digital signature is a string of digital strings which can be produced only by a sender of information and cannot be forged by others, and the digital strings are used for binding the sender and the sent information and are effective proof of the authenticity of the sent information of the sender of the information.

For example, the identity of the user sending the storage request and the case ratio data to be stored carried by the storage request are bound.

For example, the case ratio data to be stored is hashed to obtain an information digest code of a fixed length, and if the case ratio data to be stored is tampered, the code of the information digest obtained after the hash operation is changed, so that data can be prevented from being tampered.

The case ratio data to be stored after the hash operation is digitally signed, the identity of the user sending the storage request is authenticated (namely, the identity of the user sending the case ratio data to be stored is authenticated), and the identity of the user sending the storage request is bound with the case ratio data to be stored to obtain encrypted data.

203. And broadcasting the encrypted data to a second node, so that the second node stores the encrypted data to the block chain based on a consensus algorithm, and the case ratio data corresponding to the query information, which is obtained by a case ratio data service platform of the terminal from the block chain to a basic service platform of the receiving block chain, is subjected to statistical analysis to obtain the case ratio, wherein the second node is a node on the block chain except the first node.

For example, the first node broadcasts the encrypted data to a second node of the block chain (i.e., other nodes except the first node in the block chain), and the second node verifies the received encrypted data, if the second node does not receive the encrypted data broadcast from the first node to the block chain before, the verification result is passed, otherwise, the verification result is not passed. And if the verification result is that the encrypted data passes, the second node compresses the encrypted data to form a block to be identified, and stores the block to be identified to the block chain based on an identification algorithm.

In one embodiment, the blockchain may be a federation chain, a plurality of different law enforcement agencies correspond to different nodes on the federation chain, the first node broadcasts the encrypted data to other nodes on the federation chain, and the other nodes on the federation chain verify the encrypted data and store the verified encrypted data on the nodes, so that the blockdata of the different nodes are consistent.

After a plurality of different law enforcement agencies store the case ratio data in the block chain, the subsequent terminal can acquire the case ratio data from the block chain for statistical analysis to obtain the case ratio. For example, the terminal can receive query information of a case ratio to be queried, which is input in a case ratio query page, through a case ratio data service platform, and generate a data acquisition request based on the query information; sending a data acquisition request carrying query information to a block chain basic service platform through a case ratio data service platform; acquiring case ratio data corresponding to the query information from the block chain through a block chain basic service platform, and sending the case ratio data to a case ratio data service platform; then, carrying out statistical analysis on the case ratio data to obtain a case ratio; and finally, outputting the case ratio through a case ratio data service platform.

The above operations can be implemented in the foregoing embodiments, and are not described in detail herein.

As shown in fig. 8, the public security organization, the inspection yard, and the court interact with the block chain basic service platform through the basic data platform, and upload case ratio data to the block chain. The case ratio data service platform interacts with the block chain basic service platform to obtain case ratio data of the alliance chain, workers of a public security organization, a detection hospital and a court access the case ratio data in the alliance chain through the case ratio data service platform and inquire the case ratio, and the process of inquiring the case ratio is shown in fig. 9, for example, after the case ratio data generated in the case handling process is uplinked (uploaded to the alliance chain) by the public security organization, the detection hospital and the court, the workers of a law enforcement agency can log in the case ratio data service platform and select the inquired case ratio/input inquiry information through the case ratio data service platform; and the case ratio data service platform acquires case ratio data from the alliance chain, calculates the case ratio and outputs the case ratio.

The basic data platform, the block chain basic service platform and the case ratio data service platform may be computer programs which are all stored in storage media of devices or device clusters corresponding to a public security organization, a hospital and a court, and the computer programs are loaded by processors of the devices or device clusters corresponding to the public security organization, the hospital and the court and are used for executing the case ratio query method based on the block chain provided by the embodiment of the application.

As shown in the figure, the method for querying case ratio based on block chain provided by the embodiment of the present application may be executed by a processor of a first node in a federation chain, where the first node may be any node in the federation chain.

Firstly, building a federation chain:

firstly, a federation chain is required to be constructed by the equipment of the public security agency, the inspection yard and the court according to the convention, and each node in the federation chain corresponds to a single equipment or an equipment cluster of the public security agency, the inspection yard or the court. Each node corresponds to block data, the block data comprises transaction records, the transaction records comprise case ratio data, and the case ratio data comprises case information and record information of litigation links; the case information comprises case number, case setting information and investigation information, and the record information of the litigation links comprises times, trial information and document information of the litigation links.

The nodes in the alliance chain can be single devices of a public security organization, a detection institute or a court, or device clusters, and the nodes in the alliance chain can communicate with each other and share data.

In an embodiment, as shown in fig. 10, the databases corresponding to the public security organization, the inspection yard and the court may include a trial library, a case standing library, a file library and a document library, where the law enforcement organization stores the case information generated in the case handling process and the record information of the litigation links in the corresponding databases, for example, after the public security organization sets up a case, the case ratio data is stored in the case standing library, and after the court examines a case, the case ratio data is stored in the trial library. And the basic data platform interacts with the block chain basic service platform to realize the storage of case ratio data in databases of a plurality of law enforcement agencies to the block chain.

As shown in fig. 11, the block chain basic service platform adopts a modular design mode, and through decoupling, the expandability and the usability of the whole platform are improved, the modular design is clear, and the expansion capability of the platform can be conveniently improved. And uploading case ratio data which needs to be uploaded to the block chain by the basic data platform to the block chain.

The basic data platform interacts with an API (application programming interface) module accessed by the SDK provided by an application access layer of the block chain basic service platform through a Software Development Kit (SDK) to realize data transmission. SDKs are a collection of development tools used by software engineers to build application software for a particular software package, software framework, hardware platform, operating system, etc.

Different channels can be added into the public security organization, the inspection yard and the court, namely channel modules of a platform service layer of the block chain basic service platform, each channel is provided with an independent account book, account book data in the channel can be acquired by adding the same channel, and law enforcement agencies of different channels cannot access the data in the channel.

The alliance chain is constructed by single equipment or equipment groups of a public security organization, a detection institute and a court, interaction is carried out between the basic data platform and the block chain basic service platform, case ratio data can be uploaded to the alliance chain for data sharing, and the terminal can obtain the data from the block chain for statistical analysis to obtain the case ratio data.

As shown in fig. 12, the specific flow of the case ratio query method based on the blockchain may be as follows:

301. and acquiring a storage request sent by the basic data platform.

Wherein, the storage request carries the case ratio data to be stored.

For example, in an embodiment, the case comparison data to be stored carried in the storage request may be case information and related investigation information formed in the case handling process of the public security institution.

In another embodiment, the case ratio data can be trial information and document information formed in the case processing process by the court.

302. And sending the storage request to a block chain basic service platform, and carrying out digital signature on case comparison data to be stored through the block chain basic service platform.

For example, the system may specifically be a Public Key Infrastructure (PKI) module, that is, a PKI management module of an application access layer of a block chain basic service platform performs certificate management on a law enforcement agency of an access node, and performs digital signature on case ratio data to be stored carried in a storage request by using a certificate, so as to ensure credibility and untrustworthiness of the case ratio data, and realize trust of the data through certificate trust.

Where PKI is an infrastructure established using public key mechanisms. As shown in fig. 13, the PKI management module adopts a three-layer Certificate Authority (CA) structure, the top layer uses a Root Certificate Authority (Root CA), the Certificate of the Root Certificate Authority is stored in an off-line manner to prevent the loss of the Certificate, the Root Certificate Authority issues the Certificate to a Subordinate Certificate Authority (Subordinate CA), the Subordinate Certificate Authority is responsible for issuing the Certificate to the final law enforcement authorities, namely, the public security agency, the court and the inspection institute, and the trust between the public security agency, the court and the inspection institute is confirmed by the parent Certificate.

The certificate adopts a digital signature mechanism and a Hash algorithm to ensure the correctness of the signed case ratio data to be stored and the authenticity of law enforcement agencies related to authentication.

The authority issuing the digital certificate is an authority responsible for issuing and managing the digital certificate, and serves as a trusted third party in the transaction to undertake the responsibility of validity check of the public key in the public key system.

303. And initiating and broadcasting the transaction through the block chain basic service platform.

For example, after the PKI management module digitally signs the case ratio data to be stored, the transaction module (i.e., the transaction module of the platform service layer of the blockchain basic service platform) initiates a transaction proposal, where the transaction proposal includes the case ratio data to be stored with the digital signature. The communication protocol layer broadcasts the transaction proposal to the other nodes of the federation chain.

The nodes in the alliance chain communicate with each other on the basis of a point-to-point communication network (Peer-to-Peer, P2P), a communication protocol Layer of a block chain basic service platform provides efficient, universal and safe network communication basic functions, unicast, multicast and broadcast of alliance chain messages are supported, point state synchronization of alliance chain links is supported, multiple protocols are supported to realize data exchange among nodes corresponding to a public Security agency, a court and a detection institute through a Gossip protocol, and case ratio data uploaded to the alliance chain are guaranteed to be safe through a Transport Layer Security protocol (TLS).

P2P is a point-to-point communication network, where all nodes are equally located and there is no centralized control mechanism.

The Gossip protocol is a protocol for data synchronization among a plurality of nodes in the P2P network, and for example, a neighboring node is randomly selected for data forwarding.

304. And storing case ratio data to a alliance chain by using a consensus algorithm through a block chain basic service platform.

For example, the chain code module may specifically execute a transaction proposal initiated by the transaction module by calling the contract code, where the transaction proposal includes case ratio data to be stored with a digital signature, and the ledger module stores the case ratio data to each node of the federation chain based on a consensus algorithm.

Secondly, after the alliance chain is constructed, case ratio query can be carried out based on the alliance chain:

as shown in fig. 14, the case ratio query may be performed based on a case ratio data service platform, the case ratio data service platform interacts with the block chain basic service platform through the SDK module to obtain case ratio data on the block chain, and writes the case ratio data into a data warehouse, and the case ratio data service platform may further provide functions such as data statistics, data analysis, and data display.

The data warehouse can be a database of a case-to-case data service platform.

305. And displaying a login page through the case ratio data service platform.

The login page can comprise a login mode selection control; the login mode can be in various modes, such as: account password verification, short message verification code verification, face recognition or fingerprint recognition, iris recognition and the like.

According to the login mode selected by the user, the identity of the user is verified, and whether the user has the access right or not is determined; and if the user has the access right, displaying a case ratio query page.

The access authority can be preset through the authority management module.

Optionally, the access control module may set a role-based access control or a resource-based access control.

For example, the case ratio condition of the staff in the whole inspection yard can be inquired by the inspection officer; the division of the inspection yard can check the case ratio of the person and the personnel in the division; other staff in the inspection yard can only inquire the condition of the case ratio of the staff. And according to the actual situation, the role is given to the staff of the inspection yard, and the access range of the staff is determined by the given role.

306. And displaying a case ratio query page through the case ratio data service platform, wherein the case ratio query page comprises a query confirmation control and an information input area.

The information input area may be one input field or a plurality of input fields. The information input area may further include prompt information, where the prompt information is used to prompt a user about the type of query information of the case ratio to be queried, which should be input in the information input area, for example, the type may be a case name, a department name, a time interval, and the like.

In an embodiment, the information input area further includes a query selection control, and the user selects, by operating the query selection control, whether the query information to be input is a case name, a department name, or a time interval.

After the user confirms that the information input is completed, the user clicks the 'query' (i.e., the query confirmation control) to perform case ratio query.

307. And responding to the confirmation operation of the query confirmation control aiming at the case ratio query page, receiving query information of the case ratio to be queried, which is input in the information input area, generating a data acquisition request based on the query information, and sending the data acquisition request to the block chain basic service platform.

For example, the terminal detects a trigger operation for the query confirmation control, and receives query information of a query range (case name, department name or time interval) indicated by the operation of the user on the query control in the information input area and the input case ratio to be queried.

308. And acquiring case ratio data on the alliance chain based on the data acquisition request through the block chain basic service platform.

The case ratio data can be the case information formed in the case handling process of the public security organization, the court and the inspection institute and the record information of the litigation link, and is uploaded to the alliance chain through the basic data platform.

For example, specifically, the block chain basic service platform receives the data acquisition request, the terminal acquires case ratio data corresponding to the query information from the block chain through the block chain basic service platform, and sends the case ratio data to the case ratio data service platform, and the case ratio data service platform stores the case ratio data to the data warehouse.

309. And counting the case ratio data in the data warehouse through the case ratio data service platform to obtain statistical data.

The method comprises the following steps of counting the number of cases and the frequency of litigation links in a time period of query information according to query information of a case ratio to be queried, which is input by a user in an input region of a case ratio query page, wherein the case information and the litigation links do not necessarily have corresponding relations; and secondly, counting the number of cases and the frequency of litigation links of the recorded information of all litigation links corresponding to the case information according to the query information of the case ratio to be queried, which is input by the user in the input region of the case ratio query page (without time limit).

For example, the case ratio data in the data warehouse is screened according to the received query information of the case ratio to be queried and the query range indicated by the operation of the user on the query control, so as to obtain the case ratio data related to the query information. And matching the case information with the record information of the litigation link, namely matching the case information of the case with the record of the litigation link to obtain statistical data if the litigation link is experienced after the case enters a judicial program.

The case ratio refers to the ratio of a case, namely a case, to the number of pieces counted in the related litigation links after entering the judicial program, and can be used as an index for reflecting case handling quality.

In the case handling process, some litigation links are indispensable procedures and are inevitable, and if the litigation links are taken as 'cases' of case ratios, the result cannot accurately reflect the case handling quality.

In one embodiment, taking criminal investigation as an example, in the event of criminal litigation, three procedures of normally approving arrest (disapproval arrest), claiming official complaint (disapproval official complaint), and first-pass judgment belong to normalized procedures and are inevitable procedures; the various litigation procedures derived or associated with the method, such as arresting (non-arresting) complaints, non-arresting checking, primary extended prosecution period, secondary extended prosecution period, tertiary extended prosecution period, primary return supplementary investigation, secondary return supplementary investigation, non-prosecution complaints, non-prosecution checking, non-prosecution complaints, withdrawal prosecution, court returns, farewed complaints, recommended postponed audition of the inspection parlor, national indemnification and the like, belong to very dynamic and unnecessary procedures.

Therefore, the statistics of the litigation links only comprise the times of the abnormal litigation links which are not obligatory procedures, and do not comprise three normal and obligatory procedures of normal approval arrest (disapproval arrest), complaint (non-complaint), and judgment by one trial.

The statistical conditions of case information and litigation links can be preset according to actual scene requirements.

310. And analyzing the statistical data through the case ratio data service platform to obtain the case ratio.

For example, the statistical data may be analyzed from a plurality of different dimensions, such as case names, departments, inspectors, case types, and the like, to obtain case ratios of the plurality of different dimensions.

The dimension can be selected by a user through operating a dimension selection control, and can also be preset according to the actual scene needs.

In one embodiment, the preset analysis dimensions are three dimensions of an inspector, a case type and a department, and the query information of the case ratio to be queried, which is input by the user in the input area of the case ratio query page, is 2018-2019. Analyzing the case ratio data between 2018 and 2019 from three dimensions of inspectors, case types and departments to obtain the case ratio of each inspector, the case ratio of different case types and the case ratio of each department (related departments handling cases) in 2018 and 2019.

Alternatively, in addition to analyzing case ratio data from different dimensions, the number of individual litigation links may be analyzed.

For example, taking criminal inspection as an example, the frequency of multiple abnormal and irreconcilable procedural litigation links in criminal inspection at a certain time period is analyzed respectively, and the influence of the abnormal and irreconcilable procedural litigation links on the case ratio is obtained.

311. And visually displaying the case ratio based on the case ratio through a case ratio data service platform.

The case ratio is displayed visually, wherein the case ratio of each department can be displayed in a bar chart form; the case ratio of a certain department is shown in the form of a broken line graph and the relation of the case ratio and the time.

The form of the visually displayed case may be various and is not limited herein.

For example, the data display module displays a case ratio display page, and the case ratio display page displays a case ratio obtained by performing statistical analysis on case ratio data.

Optionally, the case ratio display page may include a dimension selection control, the dimension selection control is for a user to operate to select a desired analysis dimension, and the representation form of the dimension selection control may be various, such as a button, an icon, and the like. The analysis dimension indicated by the user-triggered dimension selection control may be the analysis dimension of the analysis statistics of step 310.

As can be seen from the above, in the embodiment of the present application, after the storage request sent by the basic data platform is obtained, the case ratio storage request is sent to the block chain basic service platform, and the case ratio data to be stored is digitally signed by the block chain basic service platform; then, initiating and broadcasting transaction through a block chain basic service platform; storing case ratio data to a alliance chain by using a consensus algorithm through a block chain basic service platform; displaying a login page of the case ratio data service platform, and if the login is successful, displaying a case ratio query page of the case ratio data service platform, wherein the case ratio query page comprises a query confirmation control and an information input area; responding to the confirmation operation of a query confirmation control aiming at a case ratio query page, receiving query information of a case ratio to be queried, which is input in an information input area, generating a data acquisition request based on the query information, and sending the data acquisition request to a block chain basic service platform; acquiring case ratio data on a alliance chain based on a data acquisition request through a block chain basic service platform; counting case ratio data in the data warehouse through a case ratio data service platform to obtain statistical data; and analyzing the statistical data through the case ratio data service platform to obtain the case ratio.
