[0091] Specifically, after receiving the request of the cloud server, the edge cloud server performs secondary encryption on the first encrypted data generated in step 102 to generate the second encrypted data. The encryption rule of the edge cloud server can be different from the encryption rule of the scanning device, for example, using a higher strength encryption algorithm or an additional key layer to meet the security requirements of the cloud server. The secondary encryption forms a layered protection mechanism to ensure that the data is further protected during transmission between the edge cloud and the cloud.

[0092] 104. verifying the second encrypted data based on a verification rule associated with the scanning device, the edge cloud server, or the cloud server to determine a tampering likelihood of the scanning data.

[0105] As can be seen, by the above optional embodiments, by combining the device parameters of the code scanning device and the encryption level, the encryption key related to the code scanning device can be dynamically generated, thereby ensuring the security of the code scanning data in the transmission process, preventing the data from being tampered with or leaked during transmission between the code scanning device and the edge cloud server, and assisting in effectively improving the security of the ship cargo data in the code scanning operation transmission, reducing the risk of attack and tampering, and enhancing the reliability and credibility of the overall ship cargo inventory system.

[0106] As an optional embodiment, in the above steps, the first encryption key is generated according to the device parameters and the encryption level, including:

[0111] Optionally, the preset correspondence between the encryption level and the key parameter can be a mapping table or an algorithm model, which associates the encryption level with specific key attributes, and can be obtained by pre-setting by an operator or by mathematical fitting or model training on a large amount of historical data or experimental data.

[0112] Optionally, the first encryption key can be an AES symmetric key or an RSA public-private key pair.

[0113] Specifically, in the present application, the step of generating a key can be inputting the key length in the key parameter and the related device parameters such as the MAC address into the preset HMAC-SHA256 algorithm API to generate the key, or selecting a specific existing key generation algorithm according to the actual situation by an operator.

[0114] It can be seen that, by the above optional embodiments, the key parameters are dynamically determined based on the encryption level, and the encryption key is generated in combination with the device parameters, which can ensure that the encryption process adapts to different security requirements, while enhancing the complexity and security of the key, and assisting in effectively improving the security of the ship cargo data in the scanning code operation transmission, reducing the risk of being attacked and tampered, and enhancing the reliability and credibility of the overall ship cargo inventory system.

[0115] As an optional embodiment, in the above step, the second encrypted data is obtained by encrypting the first encrypted data based on the encryption rule of the edge cloud server, including:

[0116] Obtaining server parameters of the edge cloud server;

The acquisition method can include calling the API of the server, reading the system log or directly extracting data from the hardware interface.

[0120] It can be seen that, by the above optional embodiments, the encryption key is dynamically generated based on the server parameters, and the first encrypted data is encrypted twice, which can further enhance the security of the scanning code data in the transmission process, while ensuring the encryption strategy adaptability in different server environments, improving the flexibility and attack resistance of data protection, and assisting in effectively improving the security of the ship cargo data in the scanning code operation transmission, reducing the risk of being attacked and tampered, and enhancing the reliability and credibility of the overall ship cargo inventory system.

[0128] Based on the preset level determination rule, the encryption level is determined according to the cargo type and the ship type.

[0129] Specifically, according to the preset level determination rule, the encryption level suitable for subsequent encryption operation is derived in combination with the cargo type and the ship type, wherein the level determination rule can be a logical mapping table or a conditional judgment mechanism, which associates the cargo type (such as high-value cargo) and the ship type (such as long-distance transport ship) with the security requirements. Specifically, the encryption level is usually divided into multiple levels (such as low, medium and high) or a specific numerical value, reflecting the strength requirement of data protection, and used to guide the selection of key generation or encryption algorithm.

Specifically, the code scanning data may indirectly contain information related to the ship (such as transport batch or port code), and the model classifies through these information. Optionally, the ship type identification model can be a support vector machine model or a deep learning model.
