[0001] The present invention relates to the field of communication technology, and in particular to a data communication method, device, equipment and computer-readable storage medium. Background Art

[0002] Normal web (client version of website or webpage) cannot actively send UDP (User Datagram Protocol) requests. It is for this reason that most computer VPN (Virtual Private Network) software will not proxy the browser's UDP traffic. When users use VPN, the server cannot obtain the user's real IP (Internet Protocol) address, and thus cannot accurately determine the user's geographical area, resulting in the service content provided not matching the user's region.

[0003] Therefore, how to use the UDP traffic of the proxy browser to perform data communication in the presence of a VPN so that the real IP address can be obtained is a technical problem that needs to be solved by those skilled in the art. Summary of the invention

[0009] Optionally, encrypting the Internet Protocol address in the User Datagram Protocol request to obtain a key string in a target format includes:

[0010] The Internet Protocol address in the User Datagram Protocol request is encrypted using an asymmetric encryption method to obtain a key string in the target format.

[0011] Optionally, after returning the key string in the target format to the client, the method further includes:

[0015] Optionally, after decrypting the key string in the target format to obtain the real Internet Protocol address, the method further includes:

[0016] Based on the obtained real Internet Protocol addresses corresponding to the multiple clients, the service content corresponding to each client is determined by using a service partitioning strategy; wherein the service partitioning strategy is a strategy for setting different service contents for users in different regions;

[0017] Or determine whether there is abnormal operation behavior based on the real Internet Protocol address and the browser fingerprint; wherein the abnormal operation behavior refers to multi-account operation of a single Internet Protocol address.

[0018] Optionally, the service partitioning strategy is a dynamic service partitioning strategy that adjusts the service content of each region in real time according to market demand, inventory level and total cost of providing services in different regions.

[0019] Optionally, determining whether there is abnormal operation behavior based on the real Internet Protocol address and the browser fingerprint includes:

[0020] Determining whether a preset number of accounts share the same address and browser fingerprint based on the real Internet Protocol address and browser fingerprint;

[0021] When the number of accounts with the same real Internet Protocol address and the same browser fingerprint reaches a preset value, it is determined that the abnormal operation behavior exists.

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0040] Please refer to Figure 1 , Figure 1 A flow chart of a data communication method provided by an embodiment of the present invention. The method is applied to a server and may include:

[0041] S101, receiving a user datagram protocol request sent by a client based on website real-time communication; wherein the user datagram protocol request includes an Internet Protocol address.

[0042] The executor of this embodiment is a server, which is a high-performance computer used to provide computing power and run software applications in a network environment. The client in this embodiment is the party requesting the service, usually referring to the user's device or software (such as a browser, mobile application, etc.), which initiates a request to the server to obtain the required data or functions. The real-time communication of the website in this embodiment is WebRTC technology, which is an advanced technology for realizing real-time audio and video communication between browsers. It allows network applications or sites to establish point-to-point connections without the help of an intermediary through a set of APIs (Application Programming Interfaces), realizing the transmission of video streams, audio streams or other arbitrary data. The user datagram protocol request in this embodiment is a connectionless transport layer protocol, which is mainly used to quickly transmit data packets in computer networks.

[0043] It should be further explained that the application scenario of this embodiment is a network in which a VPN exists and the VPN does not support user datagram protocol requests. It is understandable that a normal web (client version of a website or webpage) cannot actively send udp (User Datagram Protocol) requests. It is for this reason that most computer VPN (virtual private network) software will not actively proxy the browser's udp traffic. Therefore, as long as udp can be used to send requests, the user's real IP address before using the vpn can be obtained.

[0044] S102, encrypting the Internet Protocol address in the User Datagram Protocol request to obtain a key string in a target format.

[0045] This embodiment does not limit the specific encryption method. For example, the encryption method in this embodiment may be asymmetric encryption; or the encryption method in this embodiment may also be symmetric encryption. This embodiment may use a signaling service to encrypt the Internet Protocol address in the user datagram protocol request. The server is the infrastructure for implementing the signaling service, and the signaling service is the key mechanism to ensure the reliability of data transmission. The signaling service refers to the service responsible for transmission in the communication network. This embodiment does not limit the specific target format, as long as it is a format acceptable to the client. For example, the target format in this embodiment may be IPv6 (Internet Protocol Version 6). IPv6 has significant advantages in personal privacy protection. By hiding the user's real IP address, it can effectively prevent the user's behavior on the Internet from being tracked and analyzed. For enterprises, IPv6 not only provides sufficient address space, but also enhances network security and data transmission efficiency, which helps to build a more stable and reliable enterprise network environment; or the target format in this embodiment may also be IPv4. It can be understood that in asymmetric encryption, the public key is public, while the private key is confidential. This design ensures that even if the public key is leaked, it will not endanger the security of the private key. Since there is no need to transmit private keys over the network, the risk of keys being intercepted during transmission is greatly reduced.

[0046] S103, returning the key string in the target format to the client.

[0047] This embodiment returns the target format key string to the client, so that when it is determined to obtain the real Internet Protocol address, an address acquisition request is sent to the client; and the target format key string returned by the client in response to the address acquisition request is received. For example, the overall process of this embodiment can be to use the signaling service to disguise the user's real Internet Protocol address as an IPv6 format key string (rtc-token) through an encrypted signature and return it to the client, which is referred to as rtc-token (target format key string). The service that needs to verify the user's real IP can require the client to bring this rtc-token, and the server verifies this rtc-token through the interface provided by the signaling service and obtains the real IP address required by the user.

[0048] A data communication method provided by an embodiment of the present invention may include: S101, receiving a user datagram protocol request sent by a client based on website real-time communication; wherein the user datagram protocol request includes an Internet Protocol address; S102, encrypting the Internet Protocol address in the user datagram protocol request to obtain a key string in a target format; S103, returning the key string in the target format to the client. Compared with the current VPN proxy communication, in which the client can change the Internet Protocol address at will, making it impossible to obtain the real Internet Protocol address, the present application uses website real-time communication for data communication during the data communication process, so that the server can always obtain the user's real Internet Protocol address, and because the Internet Protocol address of the client is encrypted by the signaling service program during the data communication process, the exposure of the Internet Protocol address of the client is prevented, thereby improving the security of data communication. Moreover, the request will not be captured in the panel of the user's browser console, so that the user can generate a key string in the target format corresponding to the real Internet Protocol address without feeling.

[0049] In order to make the present invention easier to understand, please refer to Figure 2 , Figure 2 A flowchart of a method for obtaining a real Internet Protocol address provided by an embodiment of the present invention may specifically include:

[0050] S201, when it is determined to obtain a real Internet Protocol address, an address acquisition request is sent to the client.

[0051] When a real Internet Protocol address is needed, this embodiment can send an address acquisition request related to real address acquisition to the client, which is a client that has stored the real address.

[0052] S202, receiving a key string in a target format returned by the client in response to the address acquisition request; wherein the key string in the target format is a key string encrypted according to the above data communication method.

[0053] S203, decrypting the key string in the target format to obtain a real Internet Protocol address.

[0054] This embodiment needs to use an encryption method corresponding to the encryption method when decrypting the key string.

[0055] It should be further explained that, in order to improve the correctness of the service content provided, after decrypting the key string in the target format and obtaining the real Internet Protocol address, it can also include:

[0056] S2031, based on the obtained real Internet Protocol addresses corresponding to the multiple clients, determine the service content corresponding to each client using the service partition strategy; wherein the service partition strategy is a strategy for setting different service contents for users in different regions.

[0057] This embodiment does not limit the specific service content. For example, the service content in this embodiment may be actual goods; or the service content in this embodiment may also be provided services. The service strategy in this embodiment refers to the service prices corresponding to the same service in different regions. This embodiment does not limit the specific regional division method. For example, the regional division method in this embodiment may be based on country, or the regional division method in this embodiment may also be based on province. This embodiment can implement some more accurate service zoning strategies, and can make more accurate push of content recommendations for users in different regions, thereby improving the user experience.

[0058] S2032, or determining whether there is abnormal operation behavior based on the real Internet Protocol address and the browser fingerprint; wherein the abnormal operation behavior refers to multi-account operation of a single Internet Protocol address.

[0059] The multi-account operation in this embodiment can be understood as an operation of more than one account. The browser fingerprint in this embodiment is a technology that generates a unique identifier by collecting various configuration information of the user's browser, and this identifier can be used to track the user's behavior on the Internet. It usually includes a variety of information such as operating system, browser type, screen resolution, plug-in information, etc. This embodiment does not limit the specific method of determining whether there is abnormal operation behavior based on the real Internet Protocol address and the browser fingerprint. For example, this embodiment can determine whether the number of orders corresponding to each exceeds the corresponding order data threshold based on the number of orders corresponding to the real Internet Protocol address and the number of orders corresponding to the browser fingerprint. When it exceeds, it is determined that there is an abnormal operation. That is, if a certain IP address generates a large number of orders in a short period of time, a large number of orders come from devices with the same browser fingerprint, which represents abnormal operation behavior. This embodiment determines whether there is abnormal operation behavior based on the real Internet Protocol address and the browser fingerprint at the same time, which can improve the accuracy of determining abnormal operation behavior.

[0060] It should be further explained that, in order to improve the accuracy of the service partitioning strategy, the above-mentioned service partitioning strategy is a dynamic service partitioning strategy that adjusts the service content of each region in real time according to market demand, inventory levels and the total cost of providing services in different regions. The market demand in this embodiment refers to the total demand of consumers for a certain commodity or service in a certain period of time, the inventory level refers to the quantity and status of inventory currently held by the enterprise, and the total cost of providing services in different regions refers to the sum of all costs incurred in providing services in various regions. The service partitioning strategy in this embodiment is dynamic, so that it can be adjusted in real time according to market demand, inventory levels and the total cost of providing services in different regions, which improves the accuracy of the service partitioning strategy and further improves the accuracy of subsequent service push.

[0061] It should be further explained that, in order to improve the accuracy of determining abnormal operation behavior, the above-mentioned determination of whether there is abnormal operation behavior based on the real Internet Protocol address and browser fingerprint may include: judging whether there are a preset number of accounts sharing the same address and browser fingerprint based on the real Internet Protocol address and browser fingerprint; when the number of accounts with the same real Internet Protocol address and the same browser fingerprint reaches a preset value, it is determined that there is abnormal operation behavior. In order to determine whether there is abnormal operation behavior, this embodiment sets a threshold, namely a preset value. When the number of accounts with the same real Internet Protocol address and the same browser fingerprint reaches or exceeds this threshold, it can be considered that there is abnormal operation behavior.
