Description

Technical Field

[0001] This invention relates to the field of intelligent law enforcement equipment, software and systems, specifically to an integrated system and method for handheld intelligent equipment for customs auditing. Background Technology

[0002] Customs is a state administrative organ that exercises the power of supervision and management over import and export in accordance with laws and administrative regulations. Customs has both the authority and the responsibility to supervise and manage import and export goods and means of transport entering and leaving the country.

[0003] Customs officers, when conducting field inspections and enforcement activities, have the following needs: real-time access to inspection operation information, map navigation, audio and video enforcement records, audio and video connections with customs command agencies or colleagues, remote consultations and multi-party calls, real-time access to laws and regulations, remote expert support, and real-time translation. Meanwhile, customs command agencies and customs supervisory agencies, responsible for command and supervision, also have the following needs: real-time command and support for field inspections and enforcement activities, access to, analysis of, statistics on, and management of audio and video enforcement records, recording and access to the movement trajectories of field personnel, and, when necessary, audio and video surveillance of field personnel.

[0004] To meet the aforementioned needs, a wide variety of hardware devices are required, including at least smart mobile terminals (such as tablets), audio-visual customs enforcement terminals, and law enforcement recorders. These hardware devices undoubtedly increase the physical burden and preparation workload of customs officers. In addition, the software and service systems that accompany the aforementioned hardware devices include at least the audio-visual customs enforcement terminal back-end management system, the law enforcement recorder back-end management system, and the customs audit and inspection business management application. Obviously, multiple software and service systems will consume a lot of communication resources (especially encrypted communication resources and dedicated communication channels), software development resources, and server maintenance resources.

[0005] With the increasing prevalence of special and cross-regional customs inspections, the workload and types of individual operations for customs officers have also increased. This has led to problems such as inefficient supervision methods, weak command and operational support, and low levels of informatization in the operational process. As a result, customs officers do not have comprehensive information, making it difficult to ensure that "instructions are transmitted, actions are taken, and feedback is provided in a timely manner." Furthermore, the lack of rich and efficient information sharing methods has further highlighted the problems of weak and untimely command and operational support.

[0006] If the intelligence and integration of the aforementioned hardware, software, and service systems can be improved, the work efficiency, command efficiency, and supervision efficiency of customs field inspection and enforcement activities can be greatly enhanced, while effectively reducing the cost and resource consumption of hardware, software, and service systems.

[0007] In conclusion, how to provide a highly intelligent and integrated intelligent command system for customs field inspection and enforcement activities has become an urgent problem to be solved. Summary of the Invention

[0021] Figure 2 This is a schematic diagram of the system architecture of the server-user terminal system of the present invention.

[0022] Figure 3 This is a schematic diagram of the network topology of the present invention. Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] This embodiment provides an integrated system of handheld intelligent equipment for customs auditing, which can be used to provide data support, technical support, and command and supervision functions for customs field auditing and law enforcement activities.

[0025] Please see Figure 1 The customs audit handheld intelligent equipment integrated system in this embodiment includes a mobile handheld intelligent equipment subsystem and a command and supervision subsystem.

[0026] The mobile handheld intelligent equipment subsystem is an intelligent terminal with a dedicated operating system or dedicated software application, such as a smartphone or tablet computer. Furthermore, the mobile handheld intelligent equipment subsystem should also have the function of accessing the mobile Internet.

[0027] The command and supervision subsystem is a computer with a dedicated operating system or dedicated software applications, and it should also have the ability to access the Internet.

[0028] All mobile handheld intelligent equipment subsystems are connected to all command and control subsystems.

[0029] The mobile handheld intelligent equipment subsystem integrates: The inspection action module is used to query and display customs business information related to inspection actions; In addition, a controlled command and dispatch module is used to realize information interaction with the command and supervision subsystem, realize audio / video calls with the command and supervision subsystem, realize multi-party calls with the command and supervision subsystem and / or other mobile handheld intelligent equipment subsystems, and realize audio and video recording of the inspection action process.

[0030] It should be noted that the customs business information queried and displayed in the aforementioned audit action module may include enterprise information, plan approval forms, field work request contact forms, and direct assessment information from the customs business management system, so that customs field staff can understand the basic content of the audit operation in a timely manner.

[0031] It should be noted that the information exchange between the controlled command and dispatch module and the command and supervision subsystem specifically includes text, voice, images, and location information, and its information exchange method is the same as that of instant messaging software in existing technologies.

[0032] It should be noted that audio / video calls between the controlled command and dispatch module and the command and supervision subsystem, as well as multi-party calls between the controlled command and dispatch module and the command and supervision subsystem and / or other mobile handheld intelligent equipment subsystems, can all be achieved through the SIP protocol (Session Initialization Protocol).

[0033] The command and supervision subsystem integrates: The main control and command dispatch module is used to query and display customs business information related to inspection operations, realize information interaction with the mobile handheld intelligent equipment subsystem, realize audio / video / multi-party calls / conferences with the mobile handheld intelligent equipment subsystem and / or other command and supervision subsystems, realize audio / video / audio-video monitoring of the mobile handheld intelligent equipment subsystem, display the movement trajectory of the mobile handheld intelligent equipment subsystem, initiate broadcasts to multiple mobile handheld intelligent equipment subsystems, realize communication with external communication devices, display historical call records, and display historical operation logs; In addition, there is an audio and video recording management module, which is used to query and display audio and video recordings of the inspection process.

[0034] It should be noted that the customs business information queried and displayed by the aforementioned main control and command dispatch module may include enterprise information, plan approval forms, field work request contact forms, and directly subordinate analysis information from the customs business management system, so that customs command and supervision personnel can understand the basic content of the audit operation in a timely manner.

[0035] It should be noted that the information interaction between the main control and command and dispatch module and the mobile handheld intelligent equipment subsystem (specifically implemented by the controlled command and dispatch module of the mobile handheld intelligent equipment subsystem) includes text, voice, images and location information, and its information interaction method is the same as that of instant messaging software in the existing technology.

[0036] It should be noted that audio / video / multi-party calls / conferences between the main control command and dispatch module and the mobile handheld intelligent equipment subsystem (specifically implemented by the controlled command and dispatch module of the mobile handheld intelligent equipment subsystem) and / or other command and supervision subsystems can all be achieved through the SIP protocol (Session initialization protocol).

[0037] It should be noted that audio monitoring of the mobile handheld intelligent equipment subsystem involves seamlessly activating the microphone of the subsystem and transmitting the audio data collected by the microphone back to the main control and dispatch module in real time for listening; video monitoring of the mobile handheld intelligent equipment subsystem involves seamlessly activating the imaging device of the subsystem and transmitting the video data collected by the imaging device back to the main control and dispatch module in real time for monitoring; and audio-visual monitoring of the mobile handheld intelligent equipment subsystem involves seamlessly activating the imaging device and microphone of the subsystem and transmitting the video data collected by the imaging device and the audio data collected by the microphone back to the main control and dispatch module in real time for monitoring and listening.

[0038] It should be noted that displaying the movement trajectory of the mobile handheld intelligent equipment subsystem can specifically involve displaying a series of positioning data transmitted back by the mobile handheld intelligent equipment subsystem on the customs map data provided by the customs map server (i.e., HGIS) to form a graphical movement trajectory.

[0039] It is understandable that when logging into the command and supervision subsystem, user role data (including user account, password, and permission level, etc.) can be obtained and authenticated in the authentication, authorization, account, and auditing system (i.e., the "H4A system").

[0040] Furthermore, the mobile handheld intelligent equipment subsystem also integrates an expert support module, which enables information interaction with business experts, as well as audio / video calls with business experts.

[0041] It should be noted that the aforementioned business experts can log in to a specific command and supervision subsystem to quickly achieve information exchange and audio / video calls.

[0042] Furthermore, the mobile handheld intelligent equipment subsystem also integrates: a data and regulatory support module for querying and displaying product information related to inspection operations, as well as querying and displaying regulatory documents.

[0043] Please see Figure 2 Furthermore, the customs audit handheld intelligent equipment integrated system of this embodiment is based on a server-user terminal system (which is different from the OSI model of computer networks); the server-user terminal system includes: an application layer, used to support the operation of the audit action module, controlled command and dispatch module, expert support module and data and regulatory support module integrated in the mobile handheld intelligent equipment subsystem, and used to support the operation of the main control command and dispatch module and audio and video recording management module integrated in the command and supervision subsystem; The support layer is used to provide data network name distribution services, geographic information services, log data recording, storage and query services, storage services, streaming media services and Web data services for mobile handheld intelligent equipment subsystems and / or command and supervision subsystems; The basic resource layer is used to provide network access services, data network name authentication services, data encryption services, and security protection services for mobile handheld intelligent equipment subsystems and / or command and supervision subsystems.

[0044] It is understood that the application layer is provided by the hardware and operating system of the mobile handheld intelligent equipment subsystem and the command and supervision subsystem. Its specific purpose is to support the user interface and background program processing of the various modules integrated within the mobile handheld intelligent equipment subsystem and the command and supervision subsystem. The application layer coordinates various business and technical services to quickly build customs applications and respond to business needs. The application layer mainly refers to information technology applications related to intelligent command and control of customs audit field operations, such as audit and inspection business management, intelligent command, audio and video customs enforcement terminal management, H4A, unified communications, and other applications.

[0045] The aforementioned support layer is provided by data servers and application servers deployed in customs agencies. The support layer provides services such as H4A, HGIS, logs, command and dispatch, distributed caching, video conferencing, streaming media services, and Web data services (B / S) to provide basic support capabilities, technical service capabilities, and business service capabilities for upper-layer applications, thereby accumulating key customs business and technical services and avoiding redundant construction.

[0046] The aforementioned basic resource layer is provided by the basic hardware equipment, data servers, and application servers of telecommunications operators. This layer collects data from the business site, efficiently completes network access and transmission, and protects data security, integrity, and availability through technologies such as identity authentication, access control, and data encryption. It provides secure and efficient basic support for business applications, including customs network resources, network security equipment, 4G / 5G networks, and terminal devices.

[0047] It should be noted that the commodity information related to the aforementioned inspection operation may specifically come from the customs business management system; the aforementioned institutional documents specifically include legal and regulatory documents, customs internal normative documents (such as customs internal rules and regulations, operating procedures, and operating specifications), etc., which are stored by the command and supervision subsystem and can be added, deleted, updated, and maintained by the staff using the command and supervision subsystem.

[0048] This handheld intelligent equipment integration system for customs audit is an extension and expansion of the agency-level audit business management system in directly affiliated customs offices. It is based on the business network and deployed in a distributed manner, coordinating with the monitoring and command system architecture to achieve resource sharing and interconnection. It also supports direct access to 5G audio and video law enforcement recorders, police mobile customs law enforcement terminals, etc., to realize remote command and dispatch and supervision and management.

[0049] From an overall deployment architecture perspective, it consists of three layers. The first layer primarily comprises the Customs Audit and Inspection Business Management System: deployed in the core computer room of the General Administration of Customs Information Center, it is the most basic, important, and widely used operating system for the audit and inspection department. It receives instructions from departments such as the Tax Administration Bureau and the Risk Control Bureau, and establishes and implements audit, verification, and proactive disclosure operations. An image link is created on the homepage of the Customs Audit and Inspection Business Management System, redirecting users to the command end of the intelligent command module for field audits, and providing business data support such as audit operation numbers, plan approval forms, field operation request contact forms, and enterprise information.

[0050] The second layer is the extension deployment of the General Administration's system at each directly affiliated customs office: the intelligent command module for field audits and the existing monitoring and command subsystem are deployed in the information technology rooms of the directly affiliated customs offices, and are interconnected with the General Administration's audit and inspection business management system and the audio-visual customs enforcement terminal systems of each directly affiliated customs office to achieve interoperability. It also supports direct access to Putian, Dingqiao, and Police Tong customs enforcement terminals to realize command and dispatch and supervision and management functions.

[0051] The third layer consists of on-site terminals and network equipment: First, the two existing audio-visual customs enforcement terminal devices nationwide, including those from Potevio and Dingqiao, can be connected to the audio-visual customs enforcement terminal management platform through platform cascading to achieve audio-visual interoperability. Alternatively, they can be directly connected to the intelligent command module for field operations by installing client programs. Second, there are 5G police communication customs enforcement terminals, which, relying on 5G+smart customs, 5G DNN, and national cryptographic encryption technologies, strengthen the network security and data security protection of customs enforcement terminals. The application of 5G police communication customs enforcement terminals integrates command, evidence recording, and supervision functions, promoting the portability, integration, and intelligence of terminal equipment, reducing the burden on frontline staff, and improving work efficiency.

[0052] This system enables audio and video communication between the back-end command and the front-line law enforcement, and strengthens overall command across levels (General Administration of Customs, directly affiliated customs, subordinate customs), customs districts (across directly affiliated customs), and departments (across different business departments). It also enables electronic recording of the operation process, allowing for immediate review and recording of the operation process, and immediate collection and transmission of evidence materials, thus strengthening process management.

[0053] Please see Figure 1 and Figure 3The communication connection between all mobile handheld intelligent equipment subsystems and all command and supervision subsystems specifically includes: at least some data being transmitted through a virtual leased line network with a user authentication module.

[0054] Specifically, the virtual private line network is an isolated virtual private line network based on the sinking user data plane function (UPF) technology; the user authentication module is specifically used to authenticate the data network name (DNN) of the mobile handheld intelligent equipment subsystem and / or command and supervision subsystem.

[0055] To further strengthen network protection and improve network transmission performance (e.g., higher speed, lower latency, and more connections), the customs audit handheld smart equipment integrated system in this embodiment prioritizes the "5G UPF+DNN" network service scheme. By transmitting data through an isolated virtual private line network based on User Plane Function (UPF) technology, dedicated network communication resources can be obtained to ensure high-quality network communication for customs field audit and enforcement activities. Authentication of the Data Network Name (DNN) for the mobile handheld smart equipment subsystem and / or command and supervision subsystem enhances data transmission security. Utilizing the separation of the control plane and user plane in 5G communication technology, physical-level security isolation is achieved. All user accounts of the mobile handheld smart equipment subsystem and / or command and supervision subsystem (e.g., provided by a SIM card) must sign up for customs-specific Data Network Name (DNN) information to authenticate the Data Network Name of the mobile handheld smart equipment subsystem and / or command and supervision subsystem. Name (DNN) is used for authentication; in 5G communication technology, the data transmission channel can be separated from the control information command channel (that is, at least some data is transmitted through a virtual leased line network with a user authentication module). The control information command channel is specifically responsible for addressing and routing the transmission channel. A dedicated isolated virtual leased line network based on the sinking user plane function (UPF) technology is established for the mobile handheld intelligent equipment subsystem from the base station to the command and supervision subsystem, realizing end-to-end data sinking processing, reducing data forwarding latency, and ensuring data security.

[0056] Furthermore, the communication connection between all mobile handheld intelligent equipment subsystems and all command and supervision subsystems specifically includes: at least some data being transmitted through a Virtual Private Network (VPN) based on the Secure Socket Layer (SSL) protocol; and at least some data being transmitted after being encrypted using national cryptographic algorithms (such as RSA, SM1, SM2, etc.). Through the above methods, the security of data transmission can be further improved.

[0057] Furthermore, the communication connection between all mobile handheld intelligent equipment subsystems and all command and supervision subsystems specifically includes: the command and supervision subsystems communicating with the Internet via an external access LAN equipped with firewalls and gateways; through the above methods, the isolation between the command and supervision subsystems and the Internet can be achieved, thereby improving the data security of the command and supervision subsystems and their related systems.

[0058] It should be noted that the aforementioned "at least some data" can be classified data or data that occupies a high priority in customs operations.

[0059] like Figure 3 As shown, all mobile handheld intelligent equipment subsystems access the external local area network via the 4G / 5G network service provided by the base station, and then connect to the command and supervision subsystem through security isolation devices such as firewalls, data exchange platforms, and video exchange platforms (i.e., network gateways). Compared with 4G communication technology, 5G communication technology can provide higher speed, lower latency, more connections, higher security, and more flexible business deployment methods, making it more suitable for use in customs audit and inspection intelligent command systems.

[0060] The following will use a more specific network engineering example to further illustrate the network access method of the customs audit handheld intelligent equipment integrated system in this embodiment: (1) Internet access This method is applicable to existing mobile handheld intelligent equipment subsystems, relying on security measures deployed within the external access LAN for information security protection. The mobile handheld intelligent equipment subsystem accesses the Internet via a 4G network, and then connects to the command and supervision subsystem deployed on the external access LAN. After security protection such as firewalls and network gateways, it cascades to the inspection field intelligent command module deployed on the business management network. This method is suitable for data transmission such as audio and video streams, but not for sensitive data transmission.

[0061] (2) 5G UPF+DNN network service solution This method is applicable to mobile handheld intelligent equipment subsystems based on 5G communication technology. It utilizes Data Network Name (DNN) technology, combined with security measures for external access to the local area network, to provide information security protection. After the mobile handheld intelligent equipment subsystem connects to the 5G network, it uses DNN technology to route and aggregate sessions to a designated customs-dedicated isolated virtual private line network based on the User Plane Function (UPF) technology for data transmission. This achieves a dedicated data transmission channel. Furthermore, it can use 5QI (5G QoS Identifier) ​​to differentiate data priorities, ensuring the network transmission quality of high-priority data. Finally, it connects to the external access local area network via the virtual private line network, and after security protection through firewalls and network gateways, it cascades to the intelligent command module for field operations deployed on the business management network. This method is suitable for the transmission of audio and video streams and data files.

[0062] (3) SSL VPN access Based on the aforementioned access method 2, to further enhance the data security of the customs audit and inspection handheld intelligent equipment integrated system in this embodiment, a national cryptographic security authentication service is introduced. At least some data is transmitted after being encrypted using national cryptographic algorithms (such as RSA, SM1, SM2, etc.). The mobile certificate management system provides CA, RA, and over-the-air certificate issuance services, and adopts a three-layer key structure to protect the security of critical keys, based on GM / T 0024-2014 SSL The VPN technical specification defines SSL protocol for secure communication, providing functions such as certificate applicant management, digital certificate application, digital certificate issuance / revocation, and digital certificate management. This enables digital certificate issuance, identity authentication, data transmission encryption, and data integrity protection for mobile handheld smart equipment subsystems. The mobile secure access system employs SSL and VPN technologies, adding a PCI-X interface encryption card to the gateway device. It provides hardware implementation of national cryptographic algorithms (such as RSA, SM1, and SM2), and implements two-way authentication between the digital identity certificate and the terminal, ensuring the confidentiality, integrity, and non-repudiation of information transmitted over the public network. This enables secure mobile access and applications for various mobile handheld smart equipment subsystems. The terminal hardware cryptographic card provides cryptographic and encrypted storage services for mobile handheld smart equipment subsystem access, enabling data encryption / decryption, digital signatures and signature verification, message digests, and message integrity checks, in accordance with the "Information Security Technology: Security Technical Specification for E-Government Mobile Office Systems" (GB / T35282-2017). "Mobile terminals of information systems with security protection level three and above should support digital certificates in hard media form," employing multiple encryption algorithms such as true random number generation, the national cryptographic SM1 algorithm, the national cryptographic SM2 algorithm, the national cryptographic SM3 hash algorithm, the SHA1 hash algorithm, and the RSA1024 algorithm. After the mobile handheld smart equipment subsystem with an accessory hardware password card accesses the 4G / 5G network, it automatically calls the security component to send an access request. Upon receiving the corresponding access request, the mobile security access system, in conjunction with the mobile certificate management system, performs two-way identity authentication with the smart terminal. After successful identity authentication, the mobile security access system and the smart terminal negotiate a session key, using the national cryptographic algorithms SM1 / SM4 to establish an encrypted secure channel between the mobile handheld smart equipment subsystem and the mobile security access system, ensuring the confidentiality, integrity, authenticity, and non-repudiation of data transmission. After decrypting the received data packets, the mobile security access system forwards them to the command and supervision subsystem via a data gateway and a video gateway.

[0063] The following will use more specific software manual examples to further illustrate the functions integrated into the customs audit handheld intelligent equipment integrated system of this embodiment: 1.
