[0061] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings in the embodiments of the present application. For example, the flowcharts and block diagrams in the accompanying drawings show the possible architectures, functions and operations of the systems, methods and computer program products according to multiple embodiments of the present invention. In this regard, each box in the flowchart or block diagram may represent a module, a program segment or a part of a code, and the module, a program segment or a part of a code contains one or more executable instructions for implementing the specified logical functions. It should also be noted that in some alternative implementations, the functions marked in the box may also occur in an order different from that marked in the accompanying drawings. For example, two consecutive boxes can actually be executed substantially in parallel, and they may sometimes be executed in the opposite order, depending on the functions involved. It should also be noted that each box in the block diagram and / or the flowchart, and the combination of boxes in the block diagram and / or the flowchart, can be implemented by a dedicated hardware-based system that performs a specified function or action, or can be implemented by a combination of dedicated hardware and computer instructions. In addition, the functional modules in the various embodiments of the present invention can be integrated together to form an independent part, or each module can exist separately, or two or more modules can be integrated to form an independent part.

[0062] During the research process, the applicant discovered that the current method of detecting whether the configuration file of a camera device has been tampered with is to collect image data from each node of the camera device for comparison, and to determine whether the configuration file of the camera device has been changed by cross-comparison of the image data. In this comparison method, only when the image data has changed can it be determined that the configuration file has been tampered with, but tampering with the configuration file does not necessarily cause changes in the image. For example, when parameters such as the frame rate and frame interval of the camera device are changed, the image data will not change. Therefore, the accuracy of detection through this implementation method does not meet the standard, and the comparison of image data will consume a large amount of computing resources. When multiple camera devices need to be detected, there is a problem of low efficiency.

[0063] Based on this, the embodiment of the present application provides a camera device configuration data detection method, which extracts characteristic values ​​from the camera device configuration data and compares them with the operation characteristic values ​​to confirm whether the camera device configuration data has been tampered with during operation. Figure 1 , Figure 1 The following is a schematic diagram of the steps of the camera device configuration data detection method provided in the embodiment of the present application. The camera device configuration data detection process may include the following steps:

[0064] In step S11, configuration data of the camera device is acquired, characteristic values ​​of each configuration item in the configuration data are extracted, and the characteristic values ​​are stored in a database as reference data.

[0065] The camera device may be a surveillance camera or other device that converts optical signals into electrical signals for storage or transmission. The configuration data of the camera device may include PTZ parameters of the camera equipment, which respectively represent the horizontal angle, vertical angle and focal length of the camera device. The configuration data may also include configuration items such as the bitstream parameter, bitrate parameter, frame rate, frame interval, focus parameter, focal length, image brightness, image contrast and image saturation of the camera device.

[0066] For example, after the parameters of each configuration item of the camera device are set, the configuration file of the camera device can be subjected to a benchmark solidification operation, and the characteristic values ​​of each parameter can be removed therefrom, and the characteristic values ​​can be used as benchmark data and stored in the database. The characteristic value of the parameter can be a hash value calculated by a digest algorithm, a field of a preset length selected from the parameter, or a value containing parameter information calculated using a predetermined formula based on the predetermined relationship between the data bit and the check bit.

[0067] In step S12, when the camera device is running, the Internet of Things security gateway is controlled to obtain the operating data of the camera device based on signaling.

[0068] Among them, the IoT gateway is a converter or converter that performs conversion protocols, encryption, management and filtering data functions, and is connected to the terminal and the camera device respectively. The terminal can be an electronic device with networking function, which can be a configurator of engineering equipment, a mobile phone, a tablet computer, a computer, a personal digital assistant, etc.

[0069] In step S13, the operation characteristic value of the operation data is extracted, and the operation characteristic value is compared with the characteristic value to determine whether the configuration data is changed.

[0070] Exemplarily, the operation characteristic value of the operation data is the operation parameter of each configuration item when the camera device is running, and the operation characteristic value corresponds to the characteristic value of the configuration item. For example, when the characteristic value of the configuration item is a hash value, the operation characteristic value is also a hash value. When the characteristic value of the configuration item has a field with a preset length or a value containing parameter information is calculated based on an agreed formula, the operation characteristic value also has the same meaning.

[0071] It can be seen that the embodiment of the present application extracts characteristic values ​​from the configuration data of the camera device and compares them with the operating characteristic values ​​to confirm whether the configuration data of the camera device has been tampered with during operation. Compared with comparing the complete camera device configuration file with the operating file at runtime to determine whether the file has been tampered with, it can save computing resources and process consumption and improve detection efficiency.

[0072] In addition, in the Internet of Things system, a gateway can be connected to multiple camera devices at the same time. Therefore, the camera device configuration data detection method in the embodiment of the present application can be used to simultaneously detect whether the configuration files of multiple camera devices have been tampered with during operation, which can further improve the detection efficiency and reduce the deployment cost of the Internet of Things.

[0073] In an optional embodiment, extracting the characteristic value of each configuration item in the configuration data may be calculating the output summary of each configuration item in the configuration data based on a preset summary algorithm, the output summary is the characteristic value, and the output summary may be a binary value string of a preset length. With respect to extracting the operation characteristic value of the operation data in step S13, and comparing the operation characteristic value with the characteristic value, the embodiment of the present application provides a method for comparing the operation characteristic value with the characteristic value, please refer to Figure 2 , Figure 2 A schematic diagram of the steps of comparing an operating characteristic value with a characteristic value provided in an embodiment of the present application, the process of comparing an operating characteristic value with a characteristic value may include:

[0074] In step S21, an output digest of the operation data is calculated based on the preset digest algorithm.

[0075] In step S22, the output summary of the configuration item is compared with the output summary of the operation data to see whether they are consistent.

[0076] In step S23, when the output summary of the configuration item is consistent with the output summary of the operation data, it is determined that the configuration data has not been changed, if not, it is determined that the configuration data has been tampered with.

[0077] Exemplarily, when the characteristic value is the output digest, the output digest of each configuration item in the configuration data and the output digest of the operation data can be calculated by the MD5 (Message-Digest Algorithm 5) algorithm or the Secure Hash Algorithm (SHA). In addition, the digest output algorithm can also be the Data Encryption Standard (DES) algorithm or the Advanced Encryption Standard (AES) algorithm, etc. It should be understood that in the embodiment of the present application, the output digest of the configuration item and the output digest of the operation data can also be calculated based on other digest algorithms. The basic calculation method in the digest algorithm can include remainder, remainder, length adjustment, and loop operation with link variables, etc., so as to obtain the output digest. The digest algorithm provided above is only illustrative and cannot be understood as limiting the scope of protection of the present application.

[0078] It can be seen that the embodiment of the present application calculates the output digest of the configuration item and the output digest of the operation data respectively through the digest algorithm, and determines whether the configuration data of the camera device has been tampered with during operation based on whether the values ​​of the two output digests are consistent, which can improve the efficiency of data comparison and thus improve the efficiency of detecting the security of the camera device.

[0079] In another optional embodiment, extracting the characteristic value of each configuration item in the configuration data may also be selecting a data field of a preset length from the configuration items of the configuration data; calculating the characteristic value corresponding to the configuration item based on the data field, or taking any number of characters in the data field as the characteristic value. With respect to extracting the operation characteristic value of the operation data in step S13, and comparing the operation characteristic value with the characteristic value, the embodiment of the present application provides another method for comparing the operation characteristic value with the characteristic value, please refer to Figure 3 , Figure 3 Another schematic diagram of steps for comparing an operating characteristic value with a characteristic value provided in an embodiment of the present application, the process of comparing an operating characteristic value with a characteristic value may also be:

[0080] In step S31, a data field of a preset length is selected from the operating data.

[0081] In step S32, a characteristic value of the operation data is calculated based on the data field, or any number of characters in the data field of the operation data is used as the characteristic value.

[0082] In step S33, when the characteristic value of the configuration item is consistent with the characteristic value of the operation data, it is determined that the configuration data has not been changed, if not, it is determined that the configuration data has been tampered with.

[0083] Exemplarily, in the implementation process of calculating the characteristic value corresponding to the configuration item based on the data field, a cyclic redundancy check algorithm (CRC) can be used to arbitrarily select a data field from each configuration item in the configuration file, perform a polynomial calculation on the selected data field, and attach the result to the last field of the data. The same calculation steps are performed on the running data, and a polynomial calculation is performed on the running data field corresponding to the configuration item to determine whether the results are consistent, thereby determining whether the configuration file has been tampered with.

[0084] In the process of implementing the number of any characters in the data field as a characteristic value, the parity check method can be used to determine whether the number of code "1" in the binary code is odd or even. When checking the running data, it is also determined whether the number of data summary code "1" is the same as the configuration item. Is an odd number or an even number, thereby determining whether the configuration file of the camera device has been tampered with during operation.

[0085] It can be seen that the embodiment of the present application provides another method for checking whether the configuration file has been tampered with. In actual application, the inspection method can be selected according to the specific situation, which can improve the flexibility of the inspection.

[0086] In addition, the configuration files may be rechecked using the above-mentioned multiple inspection methods to improve the accuracy of verifying whether the data has been tampered with.

[0087] Optionally, after determining whether the configuration data has changed in step S13, the method provided in the embodiment of the present application may further include:

[0088] When it is determined that the configuration data has been tampered with, the Internet of Things security gateway is controlled to restore the tampered data to the configuration data corresponding to the tampered data stored in the database based on control signaling.

[0089] And when it is determined that the configuration data has been tampered with, a warning message is sent.

[0090] Specifically, when it is determined that the PTZ parameters of the camera device have been tampered with, the gateway actively sends a control signal to the camera device to restore the PTZ parameters of the camera device to the configuration parameters of the original configuration file in the database, thereby restoring the direction of the camera device. At the same time, the administrator can also be notified by SMS, pop-up window, prompt tone or warning voice that the camera device configuration file has been tampered with.

[0091] It can be seen that after determining that the configuration file of the camera device has been tampered with, the embodiment of the present application can promptly prompt the management personnel and can also restore the tampered parameters according to the original configuration file in the database, thereby improving the stability and security of the operation of the camera device.

[0092] Optionally, for step S12, the present application embodiment provides a method for obtaining operation data from a camera device, see Figure 4 , Figure 4 A schematic diagram of a step of obtaining operation data from a camera device provided in an embodiment of the present application, the step of obtaining operation data may be:

[0093] In step S41, a detection time interval is set.

[0094] In step S42, the IoT security gateway is controlled to obtain the operating data from the camera device based on signaling after each detection time interval.

[0095] The time interval may be 1 minute, 10 minutes, or may be set according to actual conditions.

[0096] It can be seen that the embodiment of the present application can set a detection time interval to periodically detect the camera device, thereby improving the real-time performance of the detection and being able to promptly discover the camera device whose data has been tampered with.
