Therefore, we propose a multi-tenant version of the cultural tourism big data system, which brings together massive data from different tenants, covering multi-dimensional information such as tourist behavior, consumption patterns, and scenic spot traffic, and constructs a huge data set. These data not only provide a solid foundation for the precise marketing and service optimization of the cultural tourism industry, but also put forward higher requirements for data security and privacy protection.

[0030] See also Figure 1 The figure is a flowchart of a method for encrypting and processing multi-tenant cultural and tourism data in a specific embodiment, and the method includes: S101: Construct a coding key protocol for multi-tenant cultural and tourism information encryption based on segmented mapping, and configure the coding key for the multi-tenant cultural and tourism information encryption process in combination with an embedded hybrid coding method.

[0031] In some embodiments, the segmented mapping constructs the coding key protocol for multi-tenant cultural and tourism information encryption by first analyzing the type of cultural and tourism information data. Specifically, it can parse the type of cultural and tourism information, the length of the cultural and tourism information, the tenants bound to the cultural and tourism information, and the importance of the cultural and tourism information, so as to determine the segmentation standard.

[0032] This embodiment divides the cultural and tourism information data into multiple logical segments and assigns a unique identifier to each segment.

[0033] Then, a segment mapping relationship is established to record the data range of each segment and the unique identifier associated with it.

[0034] This embodiment configures the coding key generation strategy according to the segment mapping relationship, which may specifically include configuring the key length, key editing method and generation algorithm.

[0035] This embodiment generates a unique encoding key for each segment and ensures that the key is associated with the unique identifier of the segment. Combined with the embedded hybrid encoding method, the complexity and security of encryption can be improved.

[0036] This embodiment configures the generated encoding key into the encryption process to ensure that each segmented data is encrypted using its corresponding key.

[0037] S102: Set a plaintext attack defense key and construct an anti-attack coding protocol for the multi-tenant cultural and tourism information encryption process.

[0038] In some embodiments, the plaintext attack method is generally based on a known plaintext attack or a chosen plaintext attack. This embodiment takes into account the known plaintext attack or the chosen plaintext attack, and the key can be configured based on these methods. Specifically, the complexity and randomness of the key can be configured to resist brute force attacks and statistical analysis attacks.

[0039] This embodiment combines the plaintext attack defense key to construct an anti-attack coding protocol for the multi-tenant cultural and tourism information encryption process. The protocol specifies the key usage rules, key update strategy, and specific measures to defend against attacks during encryption and decryption.

[0040] S103: Perform isolation control on multi-tenant cultural and tourism information according to the number of non-encrypted coded characters, and generate a multi-tenant cultural and tourism information encryption identification bit sequence.

[0041] In some embodiments, the statistics of the number of non-encrypted characters may be the number of non-encrypted characters in the cultural and tourism information data.

[0042] Design an isolation control strategy for multi-tenant cultural and tourism information based on the number of non-encrypted characters. Ensure that data from different tenants can be effectively isolated before and after encryption to prevent data leakage and confusion.

[0043] In this embodiment, an encryption identification bit sequence is generated for each tenant and each segment. It should be noted that the sequence is used to identify the encryption status of the data, tenant information and segment information, so as to facilitate verification and recovery during the decryption process.

[0044] S104: Configure the tenant's encryption key and decryption key in combination with the elliptic curve random control method.

[0045] In some embodiments, an ECC elliptic curve cryptographic algorithm is selected to configure encryption keys and decryption keys of the tenant.

[0046] This embodiment generates and manages tenants' encryption and decryption keys based on the random control method of elliptic curves, ensuring that the key generation process has sufficient randomness and that key management complies with security specifications.

[0047] For tenant key configuration, each tenant can be configured with its own encryption key and decryption key, ensuring that the key storage and distribution process is secure and reliable to prevent key leakage.

[0048] S105: Complete decoding control through binary encryption key sequence to achieve multi-tenant cultural and tourism information isolation and encryption.

[0049] In some embodiments, the binary encryption key sequence generation is converting the tenant's encryption key into a binary encryption key sequence.

[0050] For decoding control, during the decryption process, the encrypted data is decoded using a binary encryption key sequence, verifying the correctness of the encryption identification bit sequence to ensure the consistency and integrity of the data before and after decryption.

[0051] In this way, this embodiment isolates and encrypts multi-tenant cultural and tourism information to achieve effective isolation and encryption of multi-tenant cultural and tourism information, ensuring that data of different tenants remain safe, reliable and isolated during storage and transmission, and also ensuring the security and privacy of multi-tenant cultural and tourism data.

[0052] In an embodiment of the present invention, based on step S101, a possible embodiment is given below to illustrate its specific implementation scheme in a non-limiting manner.

[0053] The specific implementation method of building a coded key protocol for multi-tenant cultural and tourism information encryption based on segment mapping usually includes the following steps: S1011: Define segment mapping method.

[0054] Analyze the type of cultural and tourism information, the length of cultural and tourism information, the tenants bound to the cultural and tourism information, and the importance of the cultural and tourism information.

[0055] Determine the segmentation criteria based on data characteristics, such as segmentation by data type, segmentation by data length, etc.

[0056] Define segmentation rules: Design specific segmentation rules based on the segmentation standards to clarify the data scope and content of each cultural and tourism information segment.

[0057] S1012: Construct a segment mapping relationship.

[0058] This embodiment provides a mapping relationship between each segment of cultural and tourism information and a unique identifier for easy identification and reference in subsequent steps.

[0059] Establish a mapping relationship between each segmented data and its unique identifier to ensure that the corresponding data segment can be quickly located through the identifier.

[0060] The segment mapping relationship is saved, and the segment mapping relationship is encrypted before saving, and then decrypted when extracted.

[0061] S1013: Define the coding key protocol for cultural and tourism information.

[0062] This embodiment defines the method of generating cultural and tourism information keys based on the segment mapping relationship. Generate an associated coding key for each segment. Formulate a key configuration strategy, including key storage, distribution, update and destruction, to ensure the security and availability of the key.

[0063] S1014: Pre-process cultural and tourism information.

[0064] The cultural and tourism information preprocessing method of this embodiment includes: before encryption, removing invalid characters from the cultural and tourism information, and converting the format of the cultural and tourism information to unify the format of the cultural and tourism information.

[0065] In this embodiment, the cultural and travel information of each segment is encrypted using its corresponding encoding key according to the segment mapping relationship. The encryption method can be implemented based on the AES encryption method and the RSA encryption method.

[0066] The encrypted data is organized in a certain format to generate encrypted data. The encrypted data includes associating and encapsulating the encrypted cultural and tourism information and the unique identifier of the segment.

[0067] In this embodiment, the encryption algorithm, key, and segment mapping relationship in the encryption process are optionally recorded for use in decryption or data recovery.

[0068] Through the above steps, a coding key protocol suitable for multi-tenant cultural and tourism information encryption can be constructed based on segment mapping to ensure data security and privacy.

[0069] On the basis of the above embodiments, in order to further improve the reliability of the multi-tenant cultural and tourism data encryption processing method provided in the above embodiments, as an implementable method, in the embodiment of step S102, when setting the plaintext attack defense key and constructing the anti-attack coding protocol of the multi-tenant cultural and tourism information encryption process, the following steps can be taken to configure the key and construct the anti-attack protocol for known plaintext attacks and selected plaintext attacks: Analyze the relationship between plaintext and ciphertext pairs and related information to infer the encryption key or encryption algorithm characteristics. Select a specific plaintext and obtain the ciphertext corresponding to the plaintext, then use the ciphertext information corresponding to the plaintext to infer the weaknesses of the encryption key or encryption algorithm, and configure the anti-attack encoding protocol for the multi-tenant cultural and tourism information encryption process.

[0070] Configure the AES encryption algorithm and use it in combination with the GCM algorithm (Galois / Counter Mode) to authenticate and encrypt data to prevent tampering and forgery.

[0071] Generate keys using a random number generator or a proven pseudo-random number generator. Configure a unique key for each tenant.

[0072] In this method, the key of each tenant is changed after a preset period of time to reduce the security risk caused by using the same key for a long time. The key is divided into multiple parts and stored in different locations or different encryption technologies are used to protect each part.

[0073] In this embodiment, a key derivation function is used to generate an encryption key for each tenant based on a master key and a tenant identifier, thereby ensuring that even if the master key is leaked, it is difficult for an attacker to directly obtain the encryption key of the tenant.

[0074] Optionally, a randomization element or noise is introduced into the encryption process to increase the difficulty for an attacker to attack using known or chosen plaintext.

[0075] Through the above steps, a key management mechanism can be set up that can effectively resist known plaintext attacks and chosen plaintext attacks, and a secure anti-attack encoding protocol can be constructed to protect the security and privacy of multi-tenant cultural and tourism information.

[0076] For step S103 of the embodiment of the present application, the specific implementation method of performing isolation control of multi-tenant cultural and tourism information according to the number of non-encrypted coded characters and generating a multi-tenant cultural and tourism information encryption identification bit sequence is intended to ensure that the data of different tenants are effectively isolated during the encryption process, and at the same time generate an identification bit sequence for distinguishing and tracking encrypted data. The following is an implementation method for implementing step S103.

[0077] Specifically, identify the cultural and travel information that needs to be encrypted. This is usually determined based on the user, the usage environment, or the system preset rules. For the cultural and travel information that needs to be encrypted, identify the corresponding characters or fields. You can use regular expressions or data parsing libraries to identify and count the number of unencrypted characters. Mark these data segments or fields for subsequent encryption processing.

[0078] In some specific embodiments, the AES encryption algorithm and the PBKDF2 key derivation function are used to generate the encryption key of the cultural travel information, and the key is stored in a database for subsequent decryption and key management.

[0079] In some embodiments, unencrypted characters or fields are encrypted according to the encryption strategy. During the encryption process, a unique encryption identification bit sequence is generated for each encrypted data. The sequence can be generated based on factors such as the encryption algorithm, key, data content, etc., for subsequent data tracking and verification.

[0080] This embodiment stores the encrypted data and the encrypted identification bit sequence securely in the database. Ensure that the data of different tenants are physically or logically isolated. Use the DBMS management module to provide isolation levels and access control functions to ensure data security. Restrict data access based on role-based access control authority management strategies.

[0081] Optionally, log information of key operations such as encryption processing, data storage, and access control is recorded to facilitate security auditing and tracing.

[0082] This embodiment implements isolation control of multi-tenant cultural and tourism information based on the number of non-encrypted coded characters, and generates an encrypted identification bit sequence for data tracking and verification. This method helps to improve the security, isolation and traceability of data, thereby protecting multi-tenant cultural and tourism information from the risk of unauthorized access and leakage.

[0083] In an exemplary embodiment, decoding control is completed through a binary encryption key sequence, and a specific implementation method for realizing multi-tenant cultural and tourism information isolation and encryption may include the following specific methods: Generate a unique encryption key for each tenant.

[0084] Convert the tenant's encryption key from raw format to binary format. The converted binary key can be used as an encryption key sequence, or split and reassembled to generate a more complex key sequence.

[0085] This embodiment can use the built-in function or library in the programming language to realize the conversion of the key. For example, in Python, the bin() function can be used to convert an integer into a binary string, and then the required binary key sequence is generated by processing the string.

[0086] Optionally, prepare the cultural and tourism information data to be encrypted, and determine the granularity and scope of encryption. Encrypt the cultural and tourism information using the converted binary encryption key sequence. The encryption process can be symmetric encryption or asymmetric encryption. Store the encrypted data.

[0087] The decoding control method of this embodiment can determine whether the decoding operation is allowed by verifying the tenant's identity and authority. By assigning a unique encryption key and binary encryption key sequence to each tenant, the data of different tenants is isolated during the encryption and decryption process. It can be seen that even if the data is intercepted during storage or transmission, the attacker cannot easily decrypt the data that does not belong to the tenant.

[0088] This embodiment completes decoding control through a binary encryption key sequence. The specific implementation method of realizing multi-tenant cultural and tourism information isolation and encryption involves key generation and storage, key binary conversion, encryption process, decoding control and multi-tenant isolation, as well as security and performance considerations.

[0089] Furthermore, as a refinement and expansion of the specific implementation methods of the above-mentioned embodiments, from the perspective of the flow of cultural and tourism information, the life cycle of cultural and tourism information includes collection, transmission, storage, processing, sharing and destruction, etc. The present application has built a key management system that uniformly manages all cultural and tourism information encryption keys. The scope of management includes key generation, storage, distribution, deletion, update, authentication, key owner identity authentication, operation log recording, etc.

[0090] The large cultural and tourism information processing system involved in this embodiment can deploy cryptographic service middleware to realize encryption and decryption of sensitive cultural and tourism information in each component. The encryption middleware is transparently embedded in the major cultural and tourism information components, and interacts with the key management system to achieve the conversion of plaintext and ciphertext of cultural and tourism information by using the computing performance of the large cultural and tourism information components themselves after securely obtaining the keys.

[0091] In some specific embodiments, in order to ensure normal operation, some optimization measures are taken in actual applications, including optimizing the service mode of the software cryptographic module and adopting a multi-threaded concurrent application calling mode to improve processing efficiency and response speed; using BASE64 encoding to encode cultural and tourism information and storing it on disk, and optimizing the BASE64 encoding method to reduce the size of cultural and tourism information and storage space; and using the CTR mode to replace the traditional ECB mode to reduce the expansion of encrypted cultural and tourism information and improve the efficiency and security of cultural and tourism information encryption.

[0092] In order to fully illustrate the specific implementation process in this embodiment, the provided multi-tenant cultural and tourism data encryption processing method also includes the following specific process.

In cryptographic protocols, generators are used to generate other key materials.

[0096] h represents a specific group element, which may be used to identify an entity or as part of a public key.

[0097] n represents the number of probabilities of accurate transmission of the encrypted bit sequence of multi-tenant data transmission. If there are multiple different data paths, and the accuracy of data transmission on each path may be different, then a probability value of accurate transmission can be assigned to each path, and n is the number of such paths.

[0098] i is the i-th in 1-n.

[0099] Then, the transfer key of the multi-tenant cultural and tourism information elliptic linear encryption is obtained as follows:

For example, when constructing encryption and decryption keys for multi-tenant data, the weight coefficient w can be used to adjust the relative importance of different data fragments in the encryption process, thereby achieving more flexible encryption control.

[0105] In some embodiments, the average mutual information is used as the linear spread spectrum feature of the tenant cultural and tourism information encryption, combined with the block cipher reconstruction scheme of multi-tenant cultural and tourism information, The inverse function controls the transmission of multi-tenant cultural and tourism information, builds a key protocol for multi-tenant cultural and tourism information encryption, and performs segmented encryption.
