In the era of big data, data, as a factor of production, is becoming increasingly crucial to the development of the cultural tourism industry and the entire socioeconomic landscape. Therefore, we have proposed a multi-tenant cultural tourism big data system. This system aggregates massive amounts of data from different tenants, covering multiple dimensions such as visitor behavior, consumption patterns, and attraction traffic, creating a massive dataset. This data not only provides a solid foundation for precision marketing and service optimization in the cultural tourism industry, but also places higher demands on data security and privacy protection.

[0003] Continuous advancements in cloud computing and virtualization technologies have made multi-tenant architectures possible, allowing different tenants to share infrastructure while maintaining logical isolation and independence of their data. However, this architecture also presents data security challenges, requiring encryption solutions to not only ensure data security during transmission and storage, but also maintain flexibility and scalability in a multi-tenant environment.

[0064] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0065] See also Figure 1 The figure is a flowchart of a method for encrypting multi-tenant cultural and tourism data in a specific embodiment, the method comprising:

[0066] 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 the embedded hybrid coding method.

[0067] In some embodiments, the segmented mapping constructs a coding key protocol for multi-tenant cultural and tourism information encryption, and first analyzes the type of cultural and tourism information data. Specifically, it can parse 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, so as to determine the segmentation standard.

[0068] This embodiment divides the cultural and tourism information data into multiple logical segments and assigns a unique identifier to each segment.

[0069] Then, a segment mapping relationship is established to record the data range of each segment and the unique identifier associated with it.

[0070] This embodiment configures the encoding key generation strategy based on the segment mapping relationship, which may specifically include configuring the key length, key editing method, and generation algorithm.

[0071] 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.

[0072] This embodiment configures the generated encoding key into the encryption process to ensure that each segmented data is encrypted using its corresponding key.

[0073] S102: Set a plaintext attack defense key and construct an anti-attack coding protocol for the multi-tenant cultural and tourism information encryption process.

[0074] 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.

[0075] Specifically, the complexity and randomness of the key can be configured to resist brute force attacks and statistical analysis attacks.

[0076] This embodiment combines plaintext attack resistance keys to construct an attack-resistant coding protocol for the multi-tenant cultural and tourism information encryption process. The protocol specifies the key usage rules, key update strategy, and specific attack resistance measures during encryption and decryption.

[0077] S103: Perform isolation control of 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.

[0078] In some embodiments, the statistics of the number of non-encrypted characters can count the number of non-encrypted characters in the cultural and tourism information data.

[0079] Design an isolation control strategy for multi-tenant cultural and tourism information based on the number of unencrypted characters. Ensure that data from different tenants remains effectively isolated before and after encryption to prevent data leakage and confusion.

[0080] 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.

[0081] S104: Configure the tenant's encryption key and decryption key in combination with the elliptic curve random control method.

[0082] In some embodiments, an ECC elliptic curve cryptography algorithm is selected to configure the encryption key and decryption key of the tenant.

[0083] This embodiment uses elliptic curve random control to generate and manage tenant encryption and decryption keys, ensuring that the key generation process is sufficiently random and that key management complies with security standards.

[0084] For tenant key configuration, you can configure unique encryption and decryption keys for each tenant, ensuring that the key storage and distribution process is secure and reliable to prevent key leakage.

[0085] S105: Complete decoding control through binary encryption key sequence to achieve multi-tenant cultural and tourism information isolation and encryption.

[0086] In some embodiments, the binary encryption key sequence generation is converting the tenant's encryption key into a binary encryption key sequence.

[0087] For decoding control, during the decryption process, the binary encryption key sequence is used to decode the encrypted data. The correctness of the encryption identification bit sequence is verified to ensure the consistency and integrity of the data before and after decryption.

[0088] In this way, this embodiment effectively isolates and encrypts multi-tenant cultural and tourism information, ensuring that data from different tenants remains secure, reliable, and isolated during storage and transmission, while also ensuring the security and privacy of multi-tenant cultural and tourism data.

[0089] In an embodiment of the present invention, based on step S101, a possible embodiment will be given below to illustrate its specific implementation scheme in a non-limiting manner.

[0090] The specific implementation method of the coded key agreement for multi-tenant cultural and tourism information encryption based on segmented mapping generally includes the following steps:

[0091] S1011: Define segment mapping method.

[0092] 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.

[0093] Determine the segmentation criteria based on data characteristics, such as segmentation by data type, segmentation by data length, etc.

[0094] Define segmentation rules: Based on the segmentation standards, design specific segmentation rules to clarify the data scope and content included in each cultural and tourism information segment.

[0095] S1012: Constructing a segment mapping relationship.

[0096] This embodiment provides a mapping relationship between each segment's cultural and tourism information and a unique identifier for easy identification and reference in subsequent steps.

[0097] 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.

[0098] The segment mapping relationship is saved and encrypted before saving, and then decrypted when it is retrieved.

[0099] S1013: Define the encoding key protocol for cultural and tourism information.

[0100] This embodiment defines a method for generating cultural and tourism information keys based on segment mapping relationships. A coding key is generated for each segment. A key configuration strategy is developed, including key storage, distribution, update, and destruction, to ensure key security and availability.

[0101] S1014: Pre-process cultural and tourism information.

[0102] The cultural and tourism information preprocessing method of this embodiment includes: removing invalid characters from the cultural and tourism information before encryption, and converting the format of the cultural and tourism information to unify the format of the cultural and tourism information.

[0103] In this embodiment, the cultural and tourism 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 or the RSA encryption method.

[0104] The encrypted data is organized according to a certain format to generate encrypted data. The encrypted data includes associating and encapsulating the encrypted cultural and tourism information with the unique identifier of each segment.

[0105] 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.

[0106] Through the above steps, a coding key protocol suitable for multi-tenant cultural and tourism information encryption can be constructed based on segmented mapping to ensure data security and privacy.

[0107] 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 chosen plaintext attacks:

[0108] Analyze the relationship between plaintext and ciphertext pairs and related information to infer encryption keys or encryption algorithm characteristics. Select specific plaintext and obtain the corresponding ciphertext. Then, use the corresponding ciphertext information to infer encryption key or encryption algorithm weaknesses and configure attack-resistant encoding protocols for the multi-tenant cultural and tourism information encryption process.

[0109] Configure the AES encryption algorithm and use it in combination with the GCM algorithm (Galois / Counter Mode) to provide authentication and encryption to prevent tampering and forgery.

[0110] Generate keys using a random number generator or a verified pseudo-random number generator. Configure a unique key for each tenant.

[0111] In this method, each tenant's key is rotated after a preset period of time to reduce the security risks caused by using the same key for a long time. The key is split into multiple parts and stored in different locations or protected using different encryption technologies.

[0112] In this embodiment, a master key is defined and combined with a tenant identifier, and a key derivation function is used to generate each tenant's encryption key. This ensures that even if the master key is leaked, it is difficult for an attacker to directly obtain the tenant's encryption key.

[0113] Optionally, a randomization element or noise is introduced into the encryption process to increase the difficulty for an attacker to launch an attack using known or chosen plaintext.

[0114] Through the above steps, a key management mechanism that can effectively resist known plaintext attacks and chosen plaintext attacks can be set up, and a secure anti-attack encoding protocol can be constructed to protect the security and privacy of multi-tenant cultural and tourism information.

[0115] In step S103 of this embodiment, the specific implementation method for isolating and controlling multi-tenant cultural and tourism information based on the number of unencrypted characters and generating a multi-tenant cultural and tourism information encryption identification bit sequence is intended to ensure that data from different tenants is effectively isolated during the encryption process, while also generating an identification bit sequence for distinguishing and tracking encrypted data. The following is one implementation method for step S103.

[0116] Specifically, identify the cultural and travel information that requires encryption. This is typically determined based on the user, usage environment, or system-defined rules. For the cultural and travel information that requires encryption, identify the corresponding characters or fields. Regular expressions or data parsing libraries can be used to identify and count unencrypted characters. These data segments or fields are then marked for subsequent encryption.

[0117] In some specific embodiments, the AES encryption algorithm and the PBKDF2 key derivation function are used to generate an encryption key for the cultural and travel information, and the key is stored in a database for subsequent decryption and key management.

[0118] In some embodiments, unencrypted characters or fields are encrypted according to the encryption policy. During the encryption process, a unique encryption identification bit sequence is generated for each encrypted data entry. The sequence can be generated based on factors such as the encryption algorithm, key, and data content, and is used for subsequent data tracking and verification.

[0119] This embodiment securely stores the encrypted data and encrypted identification bit sequence in the database, ensuring physical or logical isolation of data between different tenants. The DBMS management module provides isolation levels and access control functions to ensure data security. Role-based access control and permission management policies are used to restrict data access.

[0120] Optionally, log information of key operations such as encryption processing, data storage, and access control is recorded for security auditing and tracing.

[0121] This embodiment implements isolation control of multi-tenant cultural and tourism information based on the number of unencrypted coded characters and generates an encrypted identification bit sequence for data tracking and verification. This approach helps improve data security, isolation, and traceability, thereby protecting multi-tenant cultural and tourism information from unauthorized access and leakage risks.

[0122] In an exemplary embodiment, decoding control is completed through a binary encryption key sequence, and specific implementation methods for achieving multi-tenant cultural and tourism information isolation and encryption may include the following specific methods:

[0123] Generate a unique encryption key for each tenant.

[0124] Converts 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 or reassembled to generate a more complex key sequence.

[0125] 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.

[0126] Optionally, prepare the cultural and tourism information data to be encrypted, and determine the encryption granularity and scope. Use the converted binary encryption key sequence to encrypt the cultural and tourism information. The encryption process can be symmetric or asymmetric. The encrypted data is stored.

[0127] The decoding control method of this embodiment verifies the tenant's identity and permissions to determine whether to allow the decoding operation. By assigning each tenant a unique encryption key and binary encryption key sequence, data from different tenants is isolated during the encryption and decryption process. As can be seen, even if data is intercepted during storage or transmission, an attacker cannot easily decrypt data that does not belong to the tenant.

[0128] This embodiment completes decoding control through a binary encryption key sequence to achieve multi-tenant cultural and tourism information isolation and encryption. The specific implementation method involves key generation and storage, key binary conversion, encryption process, decoding control and multi-tenant isolation, as well as security and performance considerations.

[0129] 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. This application has established a key management system that uniformly controls all cultural and tourism information encryption keys. The scope of control includes key generation, storage, distribution, deletion, update, authentication, key owner identity identification, operation log recording, etc.

[0130] The large-scale cultural and tourism information processing system involved in this embodiment can deploy cryptographic service middleware to implement encryption and decryption of sensitive cultural and tourism information within each component. The encryption middleware transparently embeds itself into each of the major cultural and tourism information components and interacts with the key management system. After securely obtaining the key, it leverages the computing power of the large-scale cultural and tourism information components to convert plaintext into ciphertext.

[0131] 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.

[0132] In order to fully illustrate the specific implementation process of this embodiment, the provided multi-tenant cultural and tourism data encryption processing method also includes the following specific process.

[0133] Multi-tenant cultural and tourism information isolation and encryption.

[0134] Here, we first build a key agreement and encoding model for multi-tenant cultural and tourism information encryption, and set the output parameters of multi-tenant cultural and tourism information transmission ,Adopt adaptive source coding method to construct the digital authentication key of multi-tenant cultural and tourism information:

[0135]

[0136] Where, (i=1,2…n) represents the probability of accurate transmission of encrypted bit sequences of multi-tenant cultural tourism information transmission, let , get the Hash transfer function expression of multi-tenant cultural and tourism information;

[0137] Represents generators, which are elements in a group that can be used to generate other elements in the group. In cryptographic protocols, generators are used to generate other key material.

[0138] h represents a specific group element, which may be used to identify an entity or as part of a public key.

[0139] n represents the probability of accurate transmission of the encrypted bit sequence for multi-tenant data transmission. If there are multiple different data paths, each with varying degrees of accuracy, each path can be assigned a probability of accurate transmission, with n being the number of such paths.

[0140] i is the i-th in 1-n.

[0141] Then, the transfer key of the multi-tenant cultural and tourism information elliptical linear encryption is obtained as follows:

[0142]

[0143] Where, It is the homomorphic fusion feature quantity of multi-tenant cultural and tourism information transmission. A link transmission protocol for encrypting multi-tenant cultural and tourism information.

[0144] x represents the Hash transfer function expression.

[0145] During the multi-tenant data encryption process, It can be understood as a parameter used to adjust the characteristics of elliptic linear encryption. It may involve data encryption strength or certain specific configurations of the encryption algorithm to ensure the security and effectiveness of data encryption.

[0146] represents the collinear feature component. In multi-tenant data encryption, λ can be understood as a metric used to measure data collinearity or feature similarity. It can help identify and process data with similar characteristics, thereby optimizing the encryption process.

[0147] Refers to the weight coefficient for multi-tenant data encryption. It may be a parameter used to adjust the importance or contribution of different parts in the encryption process. 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 segments in the encryption process, thereby achieving more flexible encryption control.

[0148] 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 the 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. The segmented encryption function is:
