Description

Technical Field

[0001] The present invention relates to the technical field of video sharing, and in particular to an access control method and system for cross-platform video resource sharing. Background Art

[0002] In the current era of rapid development of cutting-edge technologies such as artificial intelligence, big data, and cloud computing, the demand for cross-platform video resource sharing and access control is increasing day by day, and it is also facing unprecedented challenges. Because traditional video platforms often use their own unique standards and protocols when they are designed, these differences lead to frequent data interoperability problems, making it extremely difficult to achieve effective sharing of cross-platform video resources. The data island phenomenon is serious, and the effective use of resources is greatly reduced. In addition, with the increase in the number of platforms and the continuous advancement of technology, the complexity and difficulty of technology adaptation have risen sharply, which not only increases the cost of system integration, but also largely limits the pace of innovation and development potential of the entire industry.

[0003] In response to the above challenges, we innovatively designed and implemented an access control method and system for cross-platform video resource sharing. The core of this system is the introduction of the national standard cascade mechanism, which aims to break the technical barriers between different platforms through standardized means and achieve efficient, secure and flexible sharing and access control of video data. In this way, not only the utilization efficiency and access convenience of video resources are greatly improved, but also it helps to promote the entire video surveillance industry to a new stage of intelligence and standardization. Summary of the invention

[0004] The purpose of the present invention is to provide an access control method and system for cross-platform video resource sharing to solve the following technical problems:

[0005] The phenomenon of data silos is serious, and the effective use of resources is greatly reduced.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A method for access control of cross-platform video resource sharing includes the following steps:

[0008] Establish a central node to receive video resources from multiple video platforms; divide the video platforms into several groups, and randomly select one video platform from each group and mark it as a national standard node;

[0009] Get the serial number i of the current national standard node, i∈[1,n]. When 1<i<n, mark the video platform with a serial number less than i as the first platform, and start from the first platform with the smallest serial number, sequentially transmit the required shared video resources to the first platform with the next highest ranking, until they are transmitted to the national standard node; mark the video platform with a serial number greater than i as the second platform, and start from the second platform with the largest serial number, sequentially transmit the required shared video resources to the second platform with the previous highest ranking, until they are transmitted to the national standard node; when i=1, the first platform has no response; when i=n, ​​the second platform has no response; the national standard node transmits the received video resources to the central node according to the assigned encryption algorithm.

[0010] Implement a unified permission management mechanism and build an organization tree configuration function to allow users to build a video resource management system; build a resource retrieval function to find and browse the organization tree information and device list of the current platform and all its cascaded subordinate platforms.

[0011] As a further solution of the present invention: the process of each group randomly selecting a video platform marked as a national standard node is:

[0012] The video platforms of each group are sorted to generate a video platform sequence V1, V2, ..., Vn, where n represents the number of video platforms in the current group. For any group, when a video sharing instruction from the central node is received, a video platform is randomly selected from the video platform sequence as the national standard node, and the video resources to be shared are transmitted to the central node through the national standard node.

[0013] As a further solution of the present invention: the process of the national standard node transmitting the video resource to the central node according to the assigned encryption algorithm is:

[0014] Each video platform is assigned a corresponding encryption algorithm. After n national standard nodes are selected, the encryption algorithms of all video platforms in the group are reallocated so that the updated encryption algorithm of each video platform is different from the original one. At the same time, the decryption algorithm library in the central node is updated so that the decryption algorithm and the encryption algorithm are correctly matched.

[0015] As a further solution of the present invention: generate a candidate node sequence that is the same as the video platform sequence V1, V2, ..., Vn. After each video sharing is completed, the video platform corresponding to the current national standard node is removed from the candidate node sequence, and then a video platform is randomly selected from the removed candidate nodes as the next national standard node. Each time an video sharing is reached, the national standard node is reselected from the complete candidate node sequence, and a is a natural number.

[0016] As a further solution of the present invention: through the organization tree configuration function, it is used for users to build a video resource management system, and integrate the seamless sharing of multiple subordinate platforms into the video resource management system.

The device parameters include device name, original device code, original channel number, shared code, status, sharing status, shared code type, video sharing, recording sharing, and PTZ sharing.

[0020] As a further solution of the present invention: the central node is used to coordinate the overall situation, receive and integrate video resources from multiple national standard nodes, and the multiple national standard nodes act as bridges, responsible for device access, to achieve seamless cascading of video resources between the upper platform and other platforms.

[0021] As a further solution of the present invention: the resource search function includes organization tree search, list mode search, video mode search, and recording mode search. The organization tree search allows users to quickly find and browse the organization tree information of the current platform and all its cascaded subordinate platforms; through the organization tree search, the detailed information of each organization is obtained, including the organization name and the number of online and offline devices under the organization;

[0022] The list mode search performs a detailed search on the device list of the current platform and all its cascaded lower-level platforms, including the device name, device code, device status and device reporting time;

[0023] The video mode search allows users to preview the real-time video of the device mounted by the organization; in video mode, users can control the device by pan / tilt and save images of the on-site situation by clicking the screenshot function;

[0024] The recording mode retrieval allows the user to query the historical recordings of the organization's mounted devices; in the recording mode, the user can select a specific recording file for playback as needed; and the recording playback function can be used to trace the course of events or verify monitoring data.

[0025] The present invention also includes an access control system for cross-platform video resource sharing, which is used to implement the above-mentioned access control method for cross-platform video resource sharing, including:

[0026] The resource integration module is used to establish a central node for receiving video resources from multiple video platforms; the video platforms are divided into several groups, and each group randomly selects a video platform to be marked as a national standard node;

[0027] The platform transmission module is used to obtain the serial number i of the current national standard node, i∈[1,n]. When 1<i<n, the video platform with a serial number less than i is marked as the first platform, and starting from the first platform with the smallest serial number, the required shared video resources are transmitted to the first platform with the next highest ranking in sequence, until they are transmitted to the national standard node; the video platform with a serial number greater than i is marked as the second platform, and starting from the second platform with the largest serial number, the required shared video resources are transmitted to the second platform with the previous highest ranking in sequence, until they are transmitted to the national standard node; when i=1, the first platform has no response; when i=n, ​​the second platform has no response; the national standard node transmits the video resources to the central node according to the assigned encryption algorithm.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figure 1-Figure 4 As shown, the present invention is an access control method for cross-platform video resource sharing, comprising the following steps:

[0043] 1. Establishment of the central node: Establish a central node at the core of the system. The main function of this node is to coordinate the video resource management and sharing strategy of the entire system. The central node is also responsible for receiving and integrating video resources provided by national standard nodes from different resources. Through this centralized management method, it is ensured that all video resources can be effectively configured and optimized, and the efficiency of resource use and the response speed of the system are improved.

[0044] 2. Constructing national standard nodes: In order to be compatible with various video platforms and achieve seamless connection, the present invention designs multiple national standard nodes as intermediate bridges. The video platforms are divided into several groups, and each group randomly selects a video platform to be marked as a national standard node. These node services not only help the central node connect to different video platforms, but also are responsible for the actual access of video devices. Each national standard node is directly associated with one or more specific video platforms and is responsible for processing data exchange and synchronization with these platforms.

[0045] 3. Implement a unified access control strategy: Implement a unified access control strategy through a sophisticated permission management mechanism. This strategy ensures that only authorized users can access specific video resources according to their permission level. This hierarchical access control not only improves the security of the system, but also ensures that different users can get the specific services they need.

[0046] 4. Use of advanced encryption technology: In order to protect video data from being illegally obtained or leaked during transmission, the present invention uses advanced encryption technology. This technology can effectively prevent data from being intercepted or tampered with during transmission, ensuring the integrity and confidentiality of the data.

[0047] 5. Organization tree configuration function: The present invention provides an organization tree configuration function, which allows system administrators or users with corresponding permissions to define and configure the management structure of video resources according to actual needs. This flexible configuration function enables the system to adapt to various complex application scenarios and organizational structures, improving the availability and adaptability of the system.

[0048] 6. Support resource sharing and fine-grained retrieval: In addition to the basic resource sharing function, the present invention also provides a variety of resource retrieval functions, such as organization tree retrieval, list mode retrieval, video mode retrieval and recording mode retrieval. These functions enable users to easily find, browse and manage the organization tree information and device lists of the current platform and all its cascaded subordinate platforms. In addition, the system also supports the cancellation of sharing operations, providing flexible resource configuration options.

[0049] The present invention constructs an architecture system consisting of a central node and multiple national standard nodes as the basis for cross-platform video resource sharing and access control. The central node is responsible for overall planning, receiving and integrating video resources from multiple national standard nodes, and implementing a unified access control and resource sharing strategy. The national standard node is like a bridge, responsible for device access, realizing seamless cascading of video resources between the upper platform and other platforms, and solving the problem of data intercommunication.

[0050] In a preferred embodiment of the present invention, the process of each group randomly selecting a video platform marked as a national standard node is as follows:

[0051] The video platforms in each group are sorted to generate an ordered video platform sequence V1, V2, ..., Vn, where n represents the number of video platforms in the current group.

[0052] For any group, when receiving the video sharing instruction from the central node, a video platform is randomly selected from the video platform sequence as the national standard node.

[0053] The video resources that need to be shared are transmitted to the central node through the selected national standard node.

[0054] The specific process of transmitting video resources from the national standard node to the central node is as follows:

[0055] Get the serial number i of the current national standard node, where i∈[1,n].

[0056] When 1<i<n, the video platform with a sequence number less than i is marked as the first platform. Starting from the first platform with the smallest sequence number, the video resources to be shared are transmitted to the first platform with the next highest sequence number in sequence, until they are transmitted to the national standard node.

[0057] The video platform with a sequence number greater than i is marked as the second platform. Starting from the second platform with the largest sequence number, the video resources to be shared are transmitted to the second platform with the previous sequence number in sequence until they are transmitted to the national standard node.

[0058] When i=1, since there is no sequence number smaller than 1, the first platform does not respond.

[0059] When i=n, ​​since there is no sequence number greater than n, the second platform does not respond.

[0060] The national standard node transmits the video resource to the central node according to the assigned encryption algorithm.

[0061] The process of the national standard node transmitting the video resource to the central node according to the assigned encryption algorithm is as follows:

[0062] Each video platform is assigned a corresponding encryption algorithm.

[0063] After selecting n national standard nodes, the encryption algorithms of all video platforms in the group are redistributed so that the updated encryption algorithm of each video platform is different from the original one. At the same time, the decryption algorithm library in the central node is updated so that the decryption algorithm and the encryption algorithm are correctly matched.

[0064] It is worth noting that the candidate node sequence is generated to be the same as the video platform sequence V1, V2, ..., Vn. After each video sharing, the video platform corresponding to the national standard node is removed from the candidate node sequence. Then a video platform is randomly selected from the removed candidate nodes as the next national standard node. After each video sharing reaches an times (a is a natural number), the national standard node is reselected from the complete candidate node sequence.

[0065] In a preferred embodiment of the present invention, in order to further enhance the system's integration and ease of operation, a strategy is adopted to mount the lower-level platform to an organization of the upper-level platform. This architectural design allows for unified management and sharing of video resources, significantly improving the manageability and access efficiency of resources. Specifically, through the organization tree configuration function, users can build and adjust the video resource management system, which not only makes the architecture clearer, but also facilitates subsequent maintenance and upgrades. In addition, this embodiment supports the seamless sharing of video resources of multiple lower-level platforms into a unified video resource management system, thereby achieving maximum utilization and optimal configuration of resources. In a cross-platform video resource sharing system, adding a lower-level platform is a key step, which allows other video platforms to be seamlessly integrated into the system.

The application of this protocol ensures that each platform can follow the same rules and format when exchanging data, thereby avoiding compatibility issues. At the same time, the unified management of video resources using the organization tree configuration function not only simplifies the resource configuration and scheduling process, but also enhances the system's adaptability and response speed to various operational requirements.

Through this function, you can easily obtain detailed information of each organization, including its organization name and the number of online and offline devices under the organization. This information is crucial for monitoring and managing the entire video surveillance system, as it can obtain the device status of each organization in a timely manner.

[0084] In another preferred embodiment of the present invention, the list mode retrieval provides an intuitive device management interface. Through this mode, a detailed search can be performed on the device list of the current platform and all its cascaded lower-level platforms.

These parameters enable you to accurately filter out the required devices and monitor and manage their status in real time.

[0085] In another preferred embodiment of the present invention, the video mode retrieval video mode can preview the device mounted by the organization in real time, and observe the on-site situation. In addition, the device can also be pan-tilt controlled to achieve all-round and multi-angle monitoring. When an event that needs to be recorded is found, just click the screenshot function to save it.

[0086] In another preferred embodiment of the present invention, the video mode retrieval provides a convenient video query and playback function. Through this mode, historical videos of the organization's mounted devices can be easily found, and specific video files can be selected for playback as needed. Whether it is tracing back the course of an event or verifying surveillance data, the video mode provides strong support.
