Judicial investigation and control credibility monitoring method, monitoring device and monitoring system

Abstract

The application provides a judicial control credibility monitoring method, a monitoring device and a monitoring system. The method uploads a first hash value to a block chain to obtain a first block chain transaction number. If a pre-transaction service fails and the pre-transaction service recovers to a normal operating state, the control reply document of the local server in this process may be tampered with. At this time, a second hash value is calculated, and the first hash value is obtained from the block chain according to the first block chain transaction number in the database. Based on the characteristic that the block chain cannot be tampered with, if the second hash value is the same as the first hash value, it indicates that the control reply document in the local server has not been tampered with. At this time, the control reply document in the local server and the control result in the local server are sent to the pre-transaction service, thereby solving the problem that the reply document exists in the risk of being tampered with in the feedback scene of the pre-transaction service failure recovery in the prior art.

Description

Technical Field

[0001] This invention relates to the field of judicial investigation and control credibility monitoring technology, specifically to a judicial investigation and control credibility monitoring method, a judicial investigation and control credibility monitoring device, a computer program product, and a judicial investigation and control credibility monitoring system. Background Technology

[0002] During the judicial investigation and control of banks by state authorities, the bank's front-end transaction service receives and parses the investigation and control request information from various state authorities. The bank's core transaction service processes the investigation and control request information issued by the front-end transaction service, assembles the investigation and control results, and returns them to the front-end transaction service. The front-end transaction service then returns the receipt and investigation and control results to the state authorities. Some problems exist in this investigation and control process, as follows:

[0003] In scenarios where the pre-transaction service fails and is re-followed up, there is a risk that the receipt document may be tampered with.

[0004] In scenarios such as retrospective feedback, there is a risk that receipt documents may be tampered with;

[0005] It is impossible to ensure the non-repudiation of the investigation and control request information and the investigation and control results, and it is impossible to prove the credibility of the investigation and control.

[0006] Currently, there is no solution to the above problems. Summary of the Invention

[0007] The main purpose of this application is to provide a judicial investigation and control credibility monitoring method, judicial investigation and control credibility monitoring device, computer program product, and judicial investigation and control credibility monitoring system, so as to at least solve the problem of the risk of tampering with receipt documents in scenarios such as retrospective feedback in the prior art.

[0008] To achieve the above objectives, according to one aspect of this application, a method for monitoring the credibility of judicial investigation and control is provided. The method is applied to a judicial investigation and control credibility monitoring service, which is deployed on a local server and is connected to a core transaction service, a distributed storage server, a blockchain, a database, and a front-end transaction service and communication. The method includes: upon receiving an investigation and control result sent by the core transaction service, generating an investigation and control receipt document based on the investigation and control result, and storing the investigation and control receipt document and the investigation and control result on the local server and the distributed storage server. The investigation and control result represents the result of performing a judicial inquiry operation on a target account or the result of performing a judicial control operation on the target account, and the investigation and control receipt document is a receipt document representing the investigation and control result; processing the investigation and control receipt document using a hash algorithm to obtain... The system obtains a first hash value, uploads it to the blockchain to obtain a first blockchain transaction number, and stores the first blockchain transaction number in the database. If the front-end transaction service fails and then resumes normal operation, the system retrieves the first blockchain transaction number from the database and, based on this number, obtains the first hash value from the blockchain. The system also retrieves the control receipt and the control result from the local server and processes the control receipt in the local server using a hash algorithm to obtain a second hash value. If the first hash value and the second hash value are the same, it is determined that the control receipt in the local server has not been tampered with, and the control receipt and the control result in the local server are sent to the front-end transaction service.

[0009] Optionally, the pre-transaction service communicates with the authorized agency's transaction service. After processing the control inquiry receipt document using a hash algorithm to obtain a first hash value and uploading the first hash value to the blockchain to obtain a first blockchain transaction number, the method includes: if the pre-transaction service does not fail, retrieving the control inquiry receipt document and the control inquiry result from the local server, sending the control inquiry receipt document and the control inquiry result from the local server to the pre-transaction service, and deleting the control inquiry receipt document and the control inquiry result from the local server; detecting whether the pre-transaction service has received a retrospective request information sent by the authorized agency's transaction service, the retrospective request information indicating a request for the pre-transaction service to resend the control inquiry receipt document and the control inquiry result. The investigation and control results are sent to the authorized agency's transaction service; when the front-end transaction service receives the retrospective request information sent by the authorized agency's transaction service, the investigation and control receipt document and the investigation and control results are obtained from the distributed storage server, and the investigation and control receipt document in the distributed storage server is processed using a hash algorithm to obtain a third hash value; the first blockchain transaction number is obtained from the database; based on the first blockchain transaction number in the database, the first hash value is obtained from the blockchain; if the first hash value and the third hash value are the same, it is determined that the investigation and control receipt document in the distributed storage server has not been tampered with, and the investigation and control receipt document and the investigation and control results in the distributed storage server are sent to the front-end transaction service.

The second blockchain transaction number is obtained by uploading the investigation and control request information to the blockchain, and the third blockchain transaction number is obtained by uploading the investigation and control result to the blockchain. The investigation and control request information indicates a request to perform the judicial inquiry operation or the judicial control operation on the target account. Sending the investigation and control receipt document and the investigation and control result in the distributed storage server to the pre-transaction service includes: obtaining a third target blockchain transaction number and a fourth target blockchain transaction number. The third target blockchain transaction number is the second blockchain transaction number in the investigation and control receipt document in the distributed storage server, and the fourth target blockchain transaction number is the third blockchain transaction number in the investigation and control receipt document in the distributed storage server; determining whether the third target blockchain transaction number and the fourth target blockchain transaction number exist on the blockchain; and, if the third target blockchain transaction number and the fourth target blockchain transaction number exist on the blockchain, sending the investigation and control receipt document and the investigation and control result in the distributed storage server to the pre-transaction service.

[0012] Optionally, the pre-transaction service is communicatively connected to the authorized agency's transaction service, and generates a control receipt document based on the control result, including: upon receiving a control request information sent by the authorized agency's transaction service, the pre-transaction service uploads the control request information to the blockchain to obtain a second blockchain transaction number, wherein the control request information indicates a request to perform the judicial inquiry operation or the judicial control operation on the target account; sends the control request information to the core transaction service, which, upon receiving the control request information, sends the control result to the judicial control credibility monitoring service; uploads the control result to the blockchain at least once to obtain a third blockchain transaction number; and generates the control receipt document based on the control result, the second blockchain transaction number, and the third blockchain transaction number.

[0013] Optionally, uploading the investigation and control results to the blockchain to obtain the third blockchain transaction number includes: when the investigation and control request information indicates that the judicial inquiry operation is performed on the target account and the number of bytes of the investigation and control results meets a predetermined condition, packaging the investigation and control results to obtain a data packet, processing the data packet using a hash algorithm to obtain a fourth hash value, and uploading the fourth hash value to the blockchain to obtain the third blockchain transaction number, wherein the predetermined condition is that the number of bytes of the investigation and control results is greater than or equal to a predetermined number of bytes; and when the investigation and control request information indicates that the judicial inquiry operation is performed on the target account and the number of bytes of the investigation and control results does not meet the predetermined condition, uploading the investigation and control results to the blockchain to obtain the third blockchain transaction number.

[0014] Optionally, at least the search and control results are uploaded to the blockchain to obtain the third blockchain transaction number, including: when the search and control request information indicates that the judicial control operation is to be carried out on the target account, the search and control results are uploaded to the blockchain to obtain the third blockchain transaction number.

[0015] According to another aspect of this application, a judicial investigation and control credibility monitoring device is provided. The device is applied to a judicial investigation and control credibility monitoring service, which is deployed on a local server and is connected to a core transaction service, a distributed storage server, a blockchain, a database, and a front-end transaction service and communication. The device includes: a generation and storage unit, used to generate an investigation and control receipt document based on the investigation and control result sent by the core transaction service, and store the investigation and control receipt document and the investigation and control result on the local server and the distributed storage server. The investigation and control result represents the result of performing a judicial inquiry operation on a target account or the result of performing a judicial control operation on the target account, and the investigation and control receipt document is a receipt document representing the investigation and control result; and a processing and uploading storage unit, used to process the investigation and control receipt document using a hash algorithm to obtain a first hash value, and then upload the result to the local server and the distributed storage server. The first hash value is uploaded to the blockchain to obtain a first blockchain transaction number, and the first blockchain transaction number is stored in the database; a first acquisition unit is used to acquire the first blockchain transaction number from the database when the front-end transaction service fails and the front-end transaction service resumes normal operation, and to acquire the first hash value from the blockchain based on the first blockchain transaction number in the database; a first acquisition processing unit is used to acquire the query and control receipt document and the query and control result from the local server, and to process the query and control receipt document in the local server using a hash algorithm to obtain a second hash value; a first determination and sending unit is used to determine that the query and control receipt document in the local server has not been tampered with when the first hash value and the second hash value are the same, and to send the query and control receipt document and the query and control result in the local server to the front-end transaction service.

[0016] According to another aspect of this application, a computer program product is provided, including a computer program / instruction that, when executed by a processor, implements any of the aforementioned judicial investigation and control credibility monitoring methods.

[0017] According to another aspect of this application, a judicial investigation and control credibility monitoring system is provided, the system comprising: a core transaction service; a distributed storage server; a blockchain; a database; a front-end transaction service, the front-end transaction service being used for communication connection with the transaction service of the competent authority; and a judicial investigation and control credibility monitoring service, the judicial investigation and control credibility monitoring service being communication connection with the core transaction service, the distributed storage server, the blockchain, the database, and the front-end transaction service, the judicial investigation and control credibility monitoring service being used to execute any of the judicial investigation and control credibility monitoring methods described above.

[0018] By applying the technical solution of this application, the hash value of the control and seizure receipt document, i.e., the first hash value, is uploaded to the blockchain to obtain the first blockchain transaction number. In scenarios such as retrospective feedback, i.e., if the competent authority's transaction service requests the pre-transaction service to resend the control and seizure receipt document and the control and seizure result to the competent authority's transaction service, and the control and seizure receipt document is stored on the distributed storage server for a long time, during which time the control and seizure receipt document in the distributed storage server may be tampered with. At this time, the hash value of the control and seizure receipt document in the distributed storage server, i.e., the third hash value, is calculated, and the first hash value is obtained from the blockchain based on the first blockchain transaction number in the database. Based on the immutable characteristic of the blockchain, if the third hash value is the same as the first hash value, it means that the control and seizure receipt document in the distributed storage server has not been tampered with. At this time, the control and seizure receipt document and the control and seizure result in the distributed storage server are sent to the pre-transaction service, thereby solving the problem of the risk of the receipt document being tampered with in scenarios such as retrospective feedback in the prior art.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] For ease of description, the following explains some of the nouns or terms used in the embodiments of this application:

[0029] Pre-transaction service: Different countries have different ways of initiating judicial investigations and controls. The pre-transaction service is used to receive and analyze judicial investigation and control request information from the competent authorities of various countries, and to provide feedback on the receipt documents and investigation and control results.

[0030] Core transaction services: Invoke multiple internal related systems, process judicial investigation and control request information, and assemble investigation and control results.

[0031] Related systems: These are typically the various core business systems and peripheral systems within a bank, handling transactions related to actual judicial inquiries and judicial control.

[0032] Blockchain: Blockchain is a decentralized, distributed, and tamper-proof data storage technology. It consists of blocks linked sequentially. Each block stores encrypted information of the data record and a reference to the previous block, and is distributed among multiple computer nodes to achieve consensus. Therefore, blockchain inherently has the characteristics of being verifiable and trustworthy.

[0033] Receipt document: After a competent state authority initiates an investigation or control measure with the bank's dedicated online investigation and control system, the system generates a document with an electronic seal and attachments, and sends the results back to the competent state authority. This document is called a "receipt document".

[0034] A blockchain transaction number (Transaction ID) is a unique identifier used to identify transactions occurring on a blockchain network. Each transaction is assigned a unique Transaction ID, which can be used to track the status of the transaction and confirm its validity. In Bitcoin and other cryptocurrency networks, a blockchain Transaction ID typically consists of a string of numbers and letters, similar to "0x1a2b3c4d5e6f7g8h9i". When users send cryptocurrency or conduct other transactions, they can use this Transaction ID to view detailed transaction information, including the sender, recipient, transaction amount, and transaction time.

[0035] As described in the background section, existing technologies pose a risk of tampering with receipt documents in scenarios such as retrospective feedback. To address this risk, embodiments of this application provide a judicial investigation and control credibility monitoring method, a judicial investigation and control credibility monitoring device, a computer program product, and a judicial investigation and control credibility monitoring system.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0037] This embodiment provides a judicial investigation and control credibility monitoring system, such as Figure 1 As shown, the above system includes:

[0038] Core transaction services;

[0039] Distributed storage server;

[0040] Blockchain;

[0041] database;

[0042] The aforementioned pre-transaction service is used for communication connections with the transaction service of authorized agencies;

[0043] The judicial investigation and control credibility monitoring service is deployed on a local server and is connected to the core transaction service, the distributed storage server, the blockchain, the database, and the front-end transaction service for communication. The judicial investigation and control credibility monitoring service is used to execute any one of the aforementioned judicial investigation and control credibility monitoring methods.

[0044] This embodiment provides a judicial investigation and control credibility monitoring method running on a judicial investigation and control credibility monitoring service. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Also, although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than that shown here.

[0045] Figure 2 This is a flowchart of a judicial investigation and control credibility monitoring method according to an embodiment of this application. Figure 2 As shown, the method includes the following steps:

[0046] Step S201: Upon receiving the investigation and control results sent by the core transaction service, generate an investigation and control receipt document based on the investigation and control results, and store the investigation and control receipt document and the investigation and control results in the local server and the distributed storage server.

[0047] The aforementioned investigation and control results refer to the results of judicial inquiry operations on the target account or the results of judicial control operations on the target account, and the aforementioned investigation and control receipt is a receipt document representing the aforementioned investigation and control results;

[0048] Specifically, the aforementioned judicial inquiry operation can be to inquire about basic information such as the opening time and location of a bank account, or transaction details, etc.; the aforementioned judicial control operation can be to freeze a bank account, etc.; the result of the aforementioned judicial inquiry operation can be basic information such as the opening time and location of a bank account, or transaction details, etc.; the result of the aforementioned judicial control operation can be whether the freezing of a bank account was successful or unsuccessful, etc.

[0049] In one alternative approach, the aforementioned pre-transaction service is communicatively connected to the authorized authority's transaction service, and step S201 can be implemented as follows:

[0050] Step S2011: After receiving the inquiry and control request information sent by the transaction service of the competent authority, the inquiry and control request information is uploaded to the blockchain to obtain the second blockchain transaction number. The inquiry and control request information indicates a request to conduct the judicial inquiry operation or the judicial control operation on the target account.

[0051] Specifically, the judicial investigation and control credibility monitoring service is connected to the pre-transaction service. Therefore, the judicial investigation and control credibility monitoring service can detect whether the pre-transaction service has received investigation and control request information sent by the competent authority's transaction service, and can obtain investigation and control request information from the pre-transaction service.

[0052] Specifically, the aforementioned judicial inquiry operations can be used to inquire about basic information such as the opening time and location of a bank account, or transaction details, while the aforementioned judicial control operations can be used to freeze, stop payment, or deduct funds from a bank account.

[0053] Step S2012: The above-mentioned investigation and control request information is sent to the above-mentioned core transaction service. The above-mentioned core transaction service is used to send the above-mentioned investigation and control result to the above-mentioned judicial investigation and control credibility monitoring service upon receiving the above-mentioned investigation and control request information.

[0054] Step S2013: Upload the above-mentioned investigation and control results to the above-mentioned blockchain to obtain the above-mentioned third blockchain transaction number;

[0055] In one alternative approach, step S2013 above can be implemented as follows:

[0056] When the above-mentioned inquiry and control request information indicates that the above-mentioned judicial inquiry operation is performed on the above-mentioned target account and the number of bytes of the above-mentioned inquiry and control result meets the predetermined conditions, the above-mentioned inquiry and control result is packaged to obtain a data packet, the above-mentioned data packet is processed by a hash algorithm to obtain a fourth hash value, and the above-mentioned fourth hash value is uploaded to the above-mentioned blockchain to obtain the above-mentioned third blockchain transaction number. The above-mentioned predetermined conditions are that the number of bytes of the above-mentioned inquiry and control result is greater than or equal to the predetermined number of bytes.

[0057] Specifically, the results of judicial inquiries may involve transaction details, resulting in a large number of bytes in the inquiry and control results. Uploading these results to the blockchain would consume a lot of resources. When the number of bytes in the inquiry and control results is greater than or equal to the predetermined number of bytes, the results are packaged into a data packet. The data packet is then processed using a hash algorithm to obtain a fourth hash value. This fourth hash value is then uploaded to the blockchain to obtain a third blockchain transaction number, thereby avoiding resource waste.

[0058] If the aforementioned investigation and control request information indicates that the aforementioned judicial inquiry operation has been performed on the aforementioned target account and the number of bytes of the aforementioned investigation and control result does not meet the aforementioned predetermined conditions, the aforementioned investigation and control result will be uploaded to the aforementioned blockchain to obtain the aforementioned third blockchain transaction number.

[0059] In one alternative approach, step S2013 above can be implemented as follows:

[0060] When the aforementioned investigation and control request information indicates that the aforementioned judicial control operation is to be carried out on the aforementioned target account, the aforementioned investigation and control results are uploaded to the aforementioned blockchain to obtain the aforementioned third blockchain transaction number.

[0061] Specifically, the result of judicial control operations is generally a feedback of failure or success. The number of bytes in the control results is very small. In this case, the control results can be directly uploaded to the blockchain without consuming a lot of resources.

[0062] Step S2014: Based on the above-mentioned investigation and control results, the above-mentioned second blockchain transaction number, and the above-mentioned third blockchain transaction number, generate the above-mentioned investigation and control receipt document.

[0063] Specifically, the investigation and control request information is uploaded to the blockchain to obtain a second blockchain transaction number, and the investigation and control result is uploaded to the blockchain to obtain a third blockchain transaction number. The second and third blockchain transaction numbers are embedded in the investigation and control receipt document. Based on the immutable nature of the blockchain, the immutability of the investigation and control request information and the investigation and control result is guaranteed, thereby ensuring the credibility of the investigation and control.

[0064] Step S202: The above-mentioned control receipt document is processed using a hash algorithm to obtain a first hash value, and the first hash value is uploaded to the above-mentioned blockchain to obtain a first blockchain transaction number, and the first blockchain transaction number is stored in the above-mentioned database;

[0065] In an alternative embodiment, the aforementioned pre-transaction service is communicatively connected to the authorized agency's transaction service. Following step S202, the method further includes:

[0066] Step S301: If the aforementioned pre-transaction service does not malfunction, retrieve the aforementioned investigation and control receipt and the aforementioned investigation and control result from the aforementioned local server, send the aforementioned investigation and control receipt and the aforementioned investigation and control result from the aforementioned local server to the aforementioned pre-transaction service, and delete the aforementioned investigation and control receipt and the aforementioned investigation and control result from the aforementioned local server.

[0067] Specifically, the judicial investigation and control credibility monitoring service is connected to the pre-transaction service, so the judicial investigation and control credibility monitoring service can detect whether the pre-transaction service is malfunctioning.

[0068] Specifically, if the pre-transaction service is functioning properly, the investigation and control receipt documents are stored on the local server for a short period of time, and the investigation and control receipt documents on the local server cannot be tampered with. In this case, the investigation and control receipt documents and the investigation and control results on the local server are sent to the pre-transaction service.

[0069] Step S302: Detect whether the aforementioned pre-transaction service has received the retrospective request information sent by the aforementioned authorized agency transaction service. The retrospective request information indicates that the aforementioned pre-transaction service is requested to resend the aforementioned investigation and control receipt and the aforementioned investigation and control results to the aforementioned authorized agency transaction service.

[0070] Step S303: When the aforementioned pre-transaction service receives the aforementioned retrospective request information sent by the aforementioned authorized agency transaction service, the aforementioned investigation and control receipt document and the aforementioned investigation and control result are obtained from the aforementioned distributed storage server, and the aforementioned investigation and control receipt document in the aforementioned distributed storage server is processed using the hash algorithm to obtain the third hash value;

[0071] Step S304: Obtain the first blockchain transaction number from the aforementioned database;

[0072] Step S305: Obtain the first hash value from the blockchain based on the first blockchain transaction number in the database.

[0073] Step S306: If the first hash value and the third hash value are the same, it is determined that the control receipt document in the distributed storage server has not been tampered with, and the control receipt document and the control result in the distributed storage server are sent to the pre-transaction service.

[0074] Specifically, the hash value of the control and seizure receipt document, i.e., the first hash value, is uploaded to the blockchain to obtain the first blockchain transaction number. In scenarios such as retrospective feedback, i.e., if the authority's transaction service requests the front-end transaction service to resend the control and seizure receipt document and the control and seizure result to the authority's transaction service, and the control and seizure receipt document is stored on the distributed storage server for a long time, during which time the control and seizure receipt document in the distributed storage server may be tampered with. At this time, the hash value of the control and seizure receipt document in the distributed storage server, i.e., the third hash value, is calculated, and the first hash value is obtained from the blockchain based on the first blockchain transaction number in the database. Based on the immutable characteristic of the blockchain, if the third hash value is the same as the first hash value, it means that the control and seizure receipt document in the distributed storage server has not been tampered with. At this time, the control and seizure receipt document and the control and seizure result in the distributed storage server are sent to the front-end transaction service, thereby solving the problem of the risk of the receipt document being tampered with in scenarios such as retrospective feedback in the existing technology.

[0075] In an optional solution, the step S306 above, which involves sending the aforementioned inquiry and control receipt document and the aforementioned inquiry and control result from the distributed storage server to the aforementioned pre-transaction service, can be implemented as follows:

[0076] Obtain the third target blockchain transaction number and the fourth target blockchain transaction number. The third target blockchain transaction number is the second blockchain transaction number in the aforementioned control and investigation receipt document in the aforementioned distributed storage server, and the fourth target blockchain transaction number is the third blockchain transaction number in the aforementioned control and investigation receipt document in the aforementioned distributed storage server.

[0077] Determine whether the aforementioned third target blockchain transaction number and the aforementioned fourth target blockchain transaction number exist on the aforementioned blockchain;

[0078] If the aforementioned third target blockchain transaction number and the aforementioned fourth target blockchain transaction number exist on the aforementioned blockchain, the aforementioned investigation and control receipt document and the aforementioned investigation and control result in the aforementioned distributed storage server will be sent to the aforementioned front-end transaction service.

[0079] Specifically, the second and third blockchain transaction numbers are obtained from the control and investigation receipt documents in the distributed storage server. The existence of the second and third blockchain transaction numbers is checked in the blockchain. If they exist, it means that the control and investigation request information and the control and investigation results are factual and have not been tampered with, and the control and investigation process is complete and without omissions. At this time, the control and investigation receipt documents and the control and investigation results in the distributed storage server are sent to the front-end transaction service.

[0080] Specifically, this application does not require additional hardware deployment in the process of detecting whether the investigation and control process is complete and without omissions, which reduces system complexity, reduces dependence on external conditions, and can simultaneously achieve anti-tampering of investigation and control receipt documents and verification of the credibility of the investigation and control process.

[0081] Step S203: If the aforementioned pre-transaction service fails and then resumes normal operation, the first blockchain transaction number is obtained from the database, and the first hash value is obtained from the blockchain based on the first blockchain transaction number in the database.

[0082] Specifically, the judicial investigation and control credibility monitoring service is connected to the pre-transaction service. Therefore, the judicial investigation and control credibility monitoring service can detect whether the pre-transaction service has malfunctioned and whether it has returned to normal operation.

[0083] Step S204: Obtain the aforementioned inquiry and control receipt and the aforementioned inquiry and control result from the aforementioned local server, and process the aforementioned inquiry and control receipt in the aforementioned local server using a hash algorithm to obtain a second hash value;

[0084] Step S205: If the first hash value and the second hash value are the same, determine that the control receipt document in the local server has not been tampered with, and send the control receipt document and the control result in the local server to the pre-transaction service.

[0085] Specifically, the hash value of the control inquiry receipt document, i.e., the first hash value, is uploaded to the blockchain to obtain the first blockchain transaction number. If the front-end transaction service fails and then resumes normal operation, the control inquiry receipt document will be stored on the local server for a long time. During this process, the control inquiry receipt document on the local server may be tampered with. At this time, the hash value of the control inquiry receipt document on the local server, i.e., the second hash value, is calculated. Based on the first blockchain transaction number in the database, the first hash value is obtained from the blockchain. Based on the immutable characteristic of the blockchain, if the second hash value is the same as the first hash value, it means that the control inquiry receipt document on the local server has not been tampered with. At this time, the control inquiry receipt document and the control inquiry result on the local server are sent to the front-end transaction service, thereby solving the problem of the risk of the receipt document being tampered with in the scenario of re-feedback after the front-end transaction service fails in the existing technology.

[0086] Specifically, since troubleshooting the pre-transaction service usually requires manual intervention and takes a certain amount of time, the query and control receipt documents on the local server may be tampered with.

[0087] Specifically, the judicial investigation and control credibility monitoring method of this application only needs to upload the hash value of the investigation and control receipt document, i.e. the first hash value, to the blockchain, without uploading the investigation and control receipt document to the blockchain, thereby reducing resource waste and ensuring the confidentiality of the investigation and control receipt document.

[0088] In an optional implementation, the step S205 above, which involves sending the aforementioned control and investigation receipt document and the aforementioned control and investigation result from the local server to the aforementioned pre-transaction service, can be achieved as follows:

[0089] Obtain the first target blockchain transaction number and the second target blockchain transaction number, wherein the first target blockchain transaction number is the second blockchain transaction number in the aforementioned control and seizure receipt document on the aforementioned local server, and the second target blockchain transaction number is the third blockchain transaction number in the aforementioned control and seizure receipt document on the aforementioned local server;

[0090] Determine whether the aforementioned first target blockchain transaction number and the aforementioned second target blockchain transaction number exist on the aforementioned blockchain;

[0091] If the aforementioned first target blockchain transaction number and the aforementioned second target blockchain transaction number exist on the aforementioned blockchain, the aforementioned investigation and control receipt document and the aforementioned investigation and control result in the aforementioned local server will be sent to the aforementioned pre-transaction service.

[0092] Specifically, the second and third blockchain transaction numbers are obtained from the control and investigation receipt documents on the local server. The existence of the second and third blockchain transaction numbers is checked on the blockchain. If they exist, it means that the control and investigation request information and the control and investigation results are factual and have not been tampered with, and the control and investigation process is complete and without omissions. At this time, the control and investigation receipt documents and the control and investigation results on the local server are sent to the front-end transaction service.

[0093] Through the above embodiments, the hash value of the control inquiry receipt document, i.e., the first hash value, is uploaded to the blockchain to obtain the first blockchain transaction number. If the front-end transaction service fails and then resumes normal operation, the control inquiry receipt document will be stored on the local server for a long time. During this process, the control inquiry receipt document on the local server may be tampered with. At this time, the hash value of the control inquiry receipt document on the local server, i.e., the second hash value, is calculated. Based on the first blockchain transaction number in the database, the first hash value is obtained from the blockchain. Based on the immutability of the blockchain, if the second hash value is the same as the first hash value, it means that the control inquiry receipt document on the local server has not been tampered with. At this time, the control inquiry receipt document and the control inquiry result on the local server are sent to the front-end transaction service, thereby solving the problem of the risk of the receipt document being tampered with in the scenario of re-feedback after the front-end transaction service fails in the prior art.

[0094] To enable those skilled in the art to better understand the technical solution of this application, the implementation process of the judicial investigation and control credibility monitoring method of this application will be described in detail below with reference to specific embodiments.

[0095] This embodiment relates to a specific method for monitoring the credibility of judicial investigation and control, such as... Figure 3 As shown, it includes the following steps:

[0096] Step S11: When the front-end transaction service receives the inquiry and control request information sent by the transaction service of the competent authority, the inquiry and control request information is uploaded to the blockchain to obtain the second blockchain transaction number (ReqTxID). The inquiry and control request information indicates a request to conduct judicial inquiry operations on the target account or to conduct judicial control operations on the target account.

[0097] Step S12: Send the investigation and control request information to the core transaction service. The core transaction service is used to send the investigation and control result to the judicial investigation and control credibility monitoring service upon receiving the investigation and control request information.

[0098] Step S13: Receive the search and control results sent by the core transaction service. The search and control results represent the results of judicial inquiry operations on the target account or judicial control operations on the target account. The search and control receipt is a receipt document representing the search and control results.

[0099] Step S14: Upload the investigation and control results to the blockchain at least to obtain a third blockchain transaction number, including:

[0100] When the information in the inquiry and control request indicates that a judicial inquiry operation is being performed on the target account and the number of bytes in the inquiry and control result meets the predetermined conditions, the inquiry and control result is packaged to obtain a data packet. The data packet is then processed using a hash algorithm to obtain a fourth hash value (QrfHash). The fourth hash value is then uploaded to the blockchain to obtain a third blockchain transaction number (at this time, the third blockchain transaction number is QrfTxID). The predetermined condition is that the number of bytes in the inquiry and control result is greater than or equal to the predetermined number of bytes.

[0101] If the information in the inquiry and control request indicates that a judicial inquiry operation is being performed on the target account and the number of bytes in the inquiry and control result does not meet the predetermined conditions, the inquiry and control result will be uploaded to the blockchain to obtain a third blockchain transaction number (at this time, the third blockchain transaction number is QrTxID).

[0102] When the information in the investigation and control request indicates that a judicial control operation is to be carried out on the target account, the investigation and control results are uploaded to the blockchain to obtain the third blockchain transaction number (at this time, the third blockchain transaction number is CrTxID);

[0103] Step S15: Generate an investigation and control receipt document based on the investigation and control results, the second blockchain transaction number, and the third blockchain transaction number;

[0104] Step S16: Process the inquiry and control receipt document using a hash algorithm to obtain the first hash value (when the inquiry and control request information indicates a judicial inquiry operation on the target account, the first hash value is QrdHash; when the inquiry and control request information indicates a judicial control operation on the target account, the first hash value is CrdHash).

[0105] Step S17: Upload the first hash value to the blockchain to obtain the first blockchain transaction number (in the case of a judicial inquiry operation on the target account represented by the inquiry and control request information, the first blockchain transaction number is QrdTxID; in the case of a judicial control operation on the target account represented by the inquiry and control request information, the first blockchain transaction number is CrdTxID), and store the first blockchain transaction number in the database.

[0106] Step S18: Store the investigation and control receipt and the investigation and control results to the local server and the distributed storage server.

[0107] This embodiment relates to a specific method for monitoring the credibility of judicial investigation and control, such as... Figure 4 As shown, it includes the following steps:

[0108] Step S21: If the front-end transaction service fails and then resumes normal operation, retrieve the first blockchain transaction number from the database (if the inquiry and control request information indicates a judicial inquiry operation on the target account, the first blockchain transaction number is QrdTxID; if the inquiry and control request information indicates a judicial control operation on the target account, the first blockchain transaction number is CrdTxID), and based on the first blockchain transaction number in the database, retrieve the first hash value from the blockchain (if the inquiry and control request information indicates a judicial inquiry operation on the target account, the first hash value is QrdHash; if the inquiry and control request information indicates a judicial control operation on the target account, the first hash value is CrdHash).

[0109] Step S22: Obtain the control inquiry receipt and control result from the local server, and process the control inquiry receipt in the local server using a hash algorithm to obtain the second hash value (DHash);

[0110] Step S23: If the first hash value and the second hash value are the same, determine that the control receipt document in the local server has not been tampered with, and send the control receipt document in the local server and the control result in the local server to the front-end transaction service.

[0111] This embodiment relates to a specific method for monitoring the credibility of judicial investigation and control, such as... Figure 5 As shown, it includes the following steps:

[0112] Step S31: Obtain the first target blockchain transaction number (ReqTxID) and the second target blockchain transaction number. The first target blockchain transaction number is the second blockchain transaction number in the investigation and control receipt document on the local server. The second target blockchain transaction number is the third blockchain transaction number in the investigation and control receipt document on the local server (when the investigation and control request information indicates a judicial inquiry operation on the target account, the third blockchain transaction number is QrfTxID or QrTxID; when the investigation and control request information indicates a judicial control operation on the target account, the third blockchain transaction number is CrTxID).

[0113] Step S32: Determine whether the first target blockchain transaction number and the second target blockchain transaction number exist on the blockchain (in the case where the investigation and control request information indicates that a judicial inquiry operation is being carried out on the target account, determine whether ReqTxID and QrfTxID exist on the blockchain, or, determine whether ReqTxID and QrTxID exist on the blockchain, in the case where the investigation and control request information indicates that a judicial control operation is being carried out on the target account, determine whether ReqTxID and CrTxID exist on the blockchain);

[0114] Step S33: If a first target blockchain transaction number and a second target blockchain transaction number exist on the blockchain, send the inquiry and control receipt document and the inquiry and control result in the local server to the front-end transaction service.
