Referring to fig. 2, based on the foregoing hardware operating environment, an embodiment of the present invention provides a block chain-based electronic commerce data transmission method, which may specifically include the following steps:
s201: the method comprises the steps that a sender node obtains electronic commerce data to be transmitted, and analyzes the electronic commerce data to be transmitted to obtain a data identifier of the electronic commerce data to be transmitted.
In this embodiment, the sender node needs to acquire the e-commerce data to be transmitted first, and analyze the data. The purpose of the parsing is to obtain a data identification of the data for proper handling during transmission. This data identification includes an area location identification and a data type identification. The regional location identity refers to the geographical location information where the e-commerce data is located. In e-commerce services, it may help the recipient node to know which region these data belong to. This information is particularly useful in some scenarios where marketing or promotion for a particular geographic region is desired. The data type identification refers to category information of the e-commerce data. In the e-commerce business, data types are various, such as commodity information, order information, user information, and the like. This identification may help the recipient node to know the kind of these data in order to process them correctly.
S202: the sender node determines a target encryption algorithm from the algorithm pool based on the e-commerce data to be transmitted and the data type identifier, and generates a target encryption key corresponding to the target encryption algorithm.
In this embodiment, the algorithm pool refers to a system or library that centrally manages a plurality of encryption algorithms, and is generally used to encrypt different types of data. In this process, the sender node needs to determine the appropriate encryption algorithm based on the data type identification. The data type identifier refers to the type to which the data belongs, such as text, images, video, and the like. Since different types of data have different characteristics, the encryption algorithms that fit them will also be different. Thus, the sender node needs to select a suitable encryption algorithm from the pool of algorithms to encrypt the data based on the data type identification.
The target encryption algorithm refers to an encryption algorithm determined from the algorithm pool according to the data type identification. The target encryption key refers to an encryption key corresponding to a target encryption algorithm, which is key information for encrypting and decrypting data. In this process, the sender node needs to first determine the data type identification of the e-commerce data to be transmitted. Once the data type identification is determined, the sender node may select a target encryption algorithm from the pool of algorithms and generate an encryption key corresponding to the target encryption algorithm. The process needs to rely on the support of an algorithm pool, wherein the algorithm pool comprises a plurality of encryption algorithms and encryption keys corresponding to the encryption algorithms, and the proper encryption algorithms and keys can be quickly selected according to different data type identifiers, so that encryption processing is completed. Once the encryption key corresponding to the target encryption algorithm is generated, the sender node can encrypt the e-commerce data to be transmitted, so that the security of the data in the transmission process is ensured.
The method comprises the following specific steps:
s202-1: basic information of a sender and a receiver is determined.
In this embodiment, in the electronic commerce data transmission process, first, the basic information of the sender and the receiver needs to be determined. This includes their identity authentication information, contact details, network addresses, etc. By determining the basic information of both parties, the accuracy and the safety of data transmission can be ensured. At the same time, it is also advantageous to determine the appropriate encryption algorithm and key.
S202-2: and constructing user information characteristics of the E-commerce data according to the basic information of the sender and the receiver and the E-commerce data to be transmitted.
In this embodiment, after the basic information of both parties is determined, the user information feature of the data needs to be constructed according to the e-commerce data to be transmitted. These characteristics may include the size of the data, the type of data, the source and destination of the data, etc. By extracting and analyzing the characteristics of the data, important references can be provided for subsequent encryption algorithm selection and key generation.
S202-3: determining the data type characteristics of the electronic commerce data according to the data type identification;
in this embodiment, after determining the user information feature of the e-commerce data, the data type feature of the e-commerce data needs to be determined according to the data type identifier. Different data types require different encryption algorithms and keys to ensure the security and accuracy of data transmission.
S202-4: and determining a target encryption algorithm from the algorithm pool according to the user information characteristics and the data type characteristics of the E-commerce data, and generating a target encryption key corresponding to the target encryption algorithm.
In this embodiment, after determining the user information feature and the data type feature of the e-commerce data, an appropriate encryption algorithm may be selected from the algorithm pool. Different encryption algorithms may need to be employed for different data types and user information characteristics. The selection of a proper encryption algorithm can improve the security and accuracy of data transmission, and the specific steps comprise:
s202-4-1: and inputting the user information characteristics and the data type characteristics of the E-commerce data into an algorithm pool to obtain the type prediction probability of the E-commerce data.
In this embodiment, it is necessary to input the user information feature and the data type feature of the e-commerce data into the algorithm pool. After these features are input into the algorithm pool, the algorithm pool processes and analyzes them to generate a probability vector that indicates the probability value that the e-commerce data belongs to different types. This probability vector may be obtained by a machine learning algorithm, such as a deep neural network or a support vector machine. The algorithms can use a large amount of electronic commerce data to carry out model training in a training stage to obtain a classifier model, and can carry out classification prediction on new electronic commerce data. Specifically, the input eigenvalues are mapped to the input layer of the model, and the corresponding probability vectors are finally output through a series of hidden layer processing.
S202-4-2: and determining a corresponding target encryption algorithm and a corresponding target encryption key based on the size of the type prediction probability of the E-commerce data.
In the present embodiment, the corresponding target encryption algorithm and key are selected according to the size of the prediction result. The prediction result may be regarded as a probability distribution of the type to which the electronic commerce data belongs, the larger the probability value is, the greater the probability of belonging to the type is. According to different probability distributions, different encryption algorithms and keys can be selected to ensure the safety of the E-commerce data. And determining the required encryption strength according to the size of the probability distribution vector. In general, the higher the maximum probability value in the probability distribution vector, the higher the encryption strength. If the maximum probability value is less than 0.5, encryption is not required. If the maximum probability value is between 0.5 and 0.8, a symmetric encryption algorithm, such as the AES algorithm, and a strong cipher may be selected for encryption. If the maximum probability value is equal to or greater than 0.8, a higher strength encryption algorithm, such as an RSA algorithm or an elliptic curve encryption algorithm, is selected. An appropriate encryption algorithm is selected based on the determined encryption strength. Different encryption algorithms, such as a symmetric encryption algorithm and an asymmetric encryption algorithm, are selected according to the difference of encryption strength. Symmetric encryption algorithms are suitable for scenes with low encryption strength requirements, and are characterized in that the same secret key is used for encryption and decryption, such as AES, DES and the like. Whereas asymmetric encryption algorithms are suitable for scenes with high encryption strength requirements, they are characterized by the use of different keys for encryption and decryption, such as RSA, ECC, etc. For the selected encryption algorithm, an appropriate key length is selected. For symmetric encryption algorithms, the key length is typically 128 bits or 256 bits. For asymmetric encryption algorithms, the key length should be long enough, typically 2048 bits or 4096 bits.
The electronic commerce data is encrypted using the selected encryption algorithm and key. And encrypting the e-commerce data by using a corresponding encryption algorithm according to the determined encryption algorithm and the key. The encrypted data can be decrypted only by persons having the correct key.

In this embodiment, first, the sender node encrypts the e-commerce data to be transmitted using the target encryption key, which is to protect the security of the data and ensure that the data is not stolen or tampered with by an unauthorized person during transmission. The encrypted e-commerce data is then compressed to generate a compressed encrypted data packet. This is to reduce the time of data transmission and the consumption of network bandwidth. The compressed data packet compresses the ciphertext data into a smaller file, which allows more data to be transmitted in a shorter time. Meanwhile, the compressed data packet can also reduce network congestion and improve the speed and stability of data transmission.

s203-1: and partitioning the e-commerce data to be encrypted according to a preset partitioning rule.
In this embodiment, the electronic commerce data is first partitioned according to a preset partitioning rule. This step may divide the larger data file into a plurality of smaller blocks for better management and processing. In the field of electronic commerce, the blocking mode can safely process data containing user privacy information. For example, an order containing customer name, address, telephone number, and credit card information may be divided into blocks to better control the security of sensitive data during encryption and transmission.
S203-2: and selecting at least one target sender node from a plurality of sender nodes, and encrypting the E-commerce data to be encrypted after the blocking by the target sender node in a safe multiparty calculation mode according to the target encryption key so as to obtain encrypted E-commerce data.
In this embodiment, one or more target sender nodes are selected and the electronic commerce data after the blocking is encrypted using the target encryption key. In this process, the data is encrypted using a secure multiparty computing method to ensure that only the target node can decrypt and read the data. This encryption scheme allows the encryption key to be shared among multiple nodes without having to transmit the key to each node. This may increase the security and reliability of the data because even if one node is attacked or compromised by the encryption key, only a portion of the data may be affected while the other data is still secure.
And compressing the encrypted E-commerce data to generate a compressed encrypted data packet, comprising the steps of:
and compressing the encrypted E-commerce data and the target encryption key by adopting a preset compression algorithm, and combining the compressed data block and the time stamp into a compressed encrypted data packet.
In this embodiment, the compression algorithm is a method of converting data into a smaller representation, thereby reducing the size and transmission time of the data. The consistency of the compression and decompression processes can be ensured by using a preset compression algorithm, and the integrity and accuracy of data after compression and decompression can be ensured. A timestamp is a marker that associates a particular time with data, which can ensure the accuracy and timeliness of the data. The compressed data blocks and the time stamps are combined into the compressed encrypted data packet, so that the data transmission is more convenient and efficient, and meanwhile, the integrity and the accuracy of the data are maintained.
S204: the sender node transmits the compressed encrypted data packet to the receiver node based on the region location identity.
In this embodiment, the compressed encrypted data packet refers to a data packet that has been compressed and encrypted, contains encrypted electronic commerce data and a target encryption key, and has been combined into a compressed encrypted data packet. The data packet can protect the security and confidentiality of data, reduce the time and risk of data transmission, and ensure the accuracy and timeliness of the data in the data transmission process. This may be done by using the area location identification to determine the location of the node and ensure that the data packet is transmitted to the correct node location. In addition, the use of compressed and encrypted data packets can also ensure the integrity and accuracy of the data. These measures can ensure the high efficiency and reliability of data transmission.
S205: the receiver node decompresses the compressed encrypted data packet and decrypts the encrypted electronic commerce data based on the target encryption key to obtain target electronic commerce data.
In this embodiment, the receiving node needs to decompress the compressed encrypted data packet and decrypt the encrypted e-commerce data based on the target encryption key to obtain the target e-commerce data. The compressed encrypted data packet is a data packet compressed and encrypted by the sender node, which contains the encrypted e-commerce data and the target encryption key, and has been combined into a compressed encrypted data packet. After the data packet is received by the receiver node, it needs to be decompressed to restore the original data content. The target encryption key is a key part for encrypting the e-commerce data, and only the correct key is used for decrypting the e-commerce data. Thus, after decompression, the recipient node needs to decrypt the encrypted e-commerce data using the target encryption key to obtain the target e-commerce data. In this process, it is very important to ensure the accuracy and security of the target encryption key. The receiver node may obtain the target e-commerce data through a decompression and decryption process. These data can be used to analyze, process and use and provide important information about the business of the electric business.
In a possible embodiment, before the step of encrypting the electronic commerce data to be transmitted, the method further comprises: judging whether the electronic commerce data to be transmitted is sensitive data or not according to the data type identifier carried in the electronic commerce data to be transmitted;
under the condition that the e-commerce data to be transmitted is sensitive data, desensitizing the e-commerce data to be transmitted to the sensitive data;
and under the condition that the e-commerce data to be transmitted is non-sensitive data, continuing to execute the step of encrypting the e-commerce data to be transmitted.
In this embodiment, before the electronic commerce data is transmitted, it is determined whether the electronic commerce data to be transmitted is sensitive data according to the carried data type identifier. In the case of sensitive data, desensitization is required to protect the privacy and security of the data. If it is not sensitive, the encryption process may be continued to protect the confidentiality of the data. Sensitive data refers to data that contains sensitive information such as personal privacy or business confidentiality. These data require special protection measures to ensure their confidentiality and security. In the process of data transmission, sensitive data needs to be specially processed so as to avoid information leakage and data theft by an attacker. And secondly, judging whether the data is sensitive data or not according to the data type identifier carried in the E-commerce data to be transmitted. If it is sensitive, it needs to be desensitized. Desensitization refers to de-labeling sensitive data to reduce its sensitivity. For example, the last digits of the identification card number may be replaced with special symbols, and the first digits and the last digits of the bank account number may be hidden, etc. By doing so, the confidentiality of data can be ensured, and the personal privacy and the security of business confidentiality can be protected. Finally, if the e-commerce data to be transmitted is not sensitive data, the encryption process can be continued. Encryption refers to the process of converting plaintext data into ciphertext data to ensure confidentiality of the data. The encryption process may be accomplished using a variety of different algorithms and keys. The encrypted data can be restored to plaintext data only after decryption using the correct key.

This information can be used to construct an e-commerce data blockchain cluster to ensure the security and reliability of e-commerce data. Second, mapping sender nodes and receiver nodes into multiple compute nodes on a two-dimensional plane can help map nodes into one space and provide a basis for subsequent blockchain network construction. For example, assuming that there are multiple merchants and customers on a map, the merchants and customers may be mapped to individual computing nodes. This process may convert the geographic location information into computer-processable digital information. Then, the two-dimensional plane is divided to obtain a plurality of sub-planes. This process may partition the two-dimensional plane into multiple sub-regions and provide a basis for subsequent blockchain network construction. For example, suppose a map is divided into a plurality of areas, each of which has a plurality of merchants and customers. This process may divide the merchant and customer into different sub-areas.
Then, the computing nodes belonging to the same sub-plane are divided into the same blockchain network to obtain a plurality of blockchain networks. This process may assign nodes to different blockchain networks based on their location information to ensure the security and reliability of the e-commerce data. For example, assume that merchants and customers are divided into different sub-regions, and that merchants and customers in each sub-region are assigned to the same blockchain network. This process may ensure that transaction information between merchants and customers is private and secure in each blockchain network.
Finally, an e-commerce data blockchain cluster is constructed based on the plurality of blockchain networks. This process may combine multiple blockchain networks and provide a basis for secure storage and transmission of e-commerce data.
