Description

Technical Field

[0001] The present application relates to the field of blockchain technology, and more specifically, to a method and apparatus for processing privacy services based on blockchain. Background Art

[0002] In recent years, driven by related industries, blockchain and privacy-preserving computing technologies have continued to develop. Both utilize a combination of cryptography and distributed systems, each with its own distinct yet complementary characteristics. Blockchain's advantages lie in its open, secure, and tamper-proof data sharing, but this also compromises data privacy. Privacy-preserving computing, on the other hand, offers advantages in its ability to maintain data privacy without being visible, but it cannot address the challenges of multi-party collaboration and trust. Privacy-preserving computing can enhance blockchain's scalability and privacy, making data traceable and data processing verifiable.

[0003] However, the integration of the two technologies is still in the exploratory stage. The general technical solution is to adopt a dual-system approach, that is, independently deploying the blockchain system and the privacy computing system, and processing privacy data through cross-system communication. However, this method has problems such as high cost, low cross-system processing efficiency, and multiple operating platforms that are inconsistent and unfriendly to users.

[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention 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 in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0029] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0030] The present invention will be described below in conjunction with preferred implementation steps. Figure 1 This is a flowchart of a method for processing a privacy service based on blockchain according to an embodiment of the present application. Figure 1 As shown, the method includes the following steps:

[0031] Step S101: Obtain the target privacy service ID, the IP addresses of multiple target smart contracts involved in the target privacy service, the communication port of each target smart contract, and the service execution order of each target smart contract for the target privacy service.

[0032] Specifically, the privacy service processing method is used in a privacy service processing system based on blockchain, such as Figure 2 As shown, the processing system includes multiple blockchain nodes. Figure 2Nodes A, B, and C in the example are the aforementioned blockchain nodes. Smart contracts are deployed on the blockchain nodes to execute blockchain transactions. A privacy-preserving computing module is also deployed on the smart contracts. When executing blockchain transactions, the smart contracts invoke the corresponding privacy-preserving computing module to complete the privacy-preserving task. When a target privacy-preserving task is pending, the target privacy-preserving task ID, the IP addresses of the multiple target smart contracts involved in the task, the communication ports for each target smart contract, and the execution order for each target smart contract are obtained. For example, if target privacy-preserving task ID 1 requires the target smart contracts on nodes A, B, and C to complete, the corresponding IP addresses and communication ports are: node A IP: 50000, node B IP: 50000, and node C IP: 50000. The execution order for the target privacy-preserving task is node A, node B, and node C.

[0033] Step S102: Based on the target privacy service ID, the internal port generated by the target smart contract is allocated to the privacy computing module corresponding to the target smart contract, the communication port of the target smart contract, and the IP address of the target smart contract.

[0034] Specifically, taking the target smart contract A on the above-mentioned node A as an example, according to the target privacy business ID1, the target smart contract A is its corresponding privacy computing module A, the IP address and communication port of the target smart contract B on node B and the IP address and communication port of the target smart contract C on node C are assigned randomly generated internal ports.

[0035] Step S103: Based on the internal port and business execution order, the target smart contract calls the privacy computing module to execute the target privacy business.

[0036] To summarize, by allocating the internal port generated by the target smart contract to the privacy computing module corresponding to the target smart contract, the communication port of the target smart contract, and the IP address of the target smart contract, and then through the above-mentioned internal port and task execution sequence, the target smart contract calls the privacy computing module to complete the privacy business, avoiding cross-system communication to complete the privacy business and improving the execution efficiency of the privacy business.

[0037] Optionally, in the blockchain-based privacy business processing method provided in the embodiment of the present application, before allocating the internal port generated by the target smart contract to the privacy computing module, the communication port of the target smart contract, and the IP address of the target smart contract corresponding to the target privacy business based on the target privacy business ID, the method also includes: sending the ID of the target privacy business, the IP addresses of multiple target smart contracts involved in the target privacy business, the communication port of each target smart contract, and the business execution order of each target smart contract for the target privacy business to each target smart contract.

[0038] Specifically, after obtaining the ID of the target privacy business, the IP addresses of multiple target smart contracts involved in the target privacy business, the communication port of each target smart contract, and the business execution order of each target smart contract for the target privacy business, the above information is sent to each target smart contract. In this way, each target smart contract can allocate internal port numbers for the IP addresses of multiple target smart contracts involved in the target privacy business and the communication port of each target smart contract based on the ID of the target privacy business.

[0039] Optionally, in the blockchain-based privacy business processing method provided in the embodiment of the present application, the internal port generated by the target smart contract is allocated to the privacy computing module corresponding to the target smart contract, the communication port of the target smart contract, and the IP address of the target smart contract based on the target privacy business ID, including: according to the target privacy business ID, the first internal port randomly generated by the target smart contract is allocated to the privacy computing module corresponding to the target smart contract to obtain a first internal port number; according to the target privacy business ID, the second internal port randomly generated by the target smart contract is allocated to the communication port of the target smart contract and the IP address of the target smart contract to obtain a second internal port number; each target smart contract saves the target privacy business ID, the first internal port number and the second internal port number in the target comparison table of each target smart contract.

[0040] Specifically, taking target smart contract A on node A as an example, for target privacy service ID 1, target smart contract A allocates a first internal port to its corresponding privacy computing module A, with the corresponding first internal port number being localhost:50001. Target smart contract A allocates a second internal port to the IP address and communication port of target smart contract B on node B, with the corresponding second port number being localhost:50002. Target smart contract A allocates a second internal port to the IP address and communication port of target smart contract C on node C, with the corresponding second port number being localhost:50003. The target privacy service ID, first internal port number, and second internal port number are saved in the target comparison table of each target smart contract. That is, target privacy service ID 1, localhost:50001, localhost:50002, and localhost:50003 are saved in target comparison table A of target smart contract A. Target smart contract B on node B and target smart contract C on node C then use the same method to allocate internal port numbers. For example, the internal port numbers assigned to target smart contract B on node B are: target privacy service ID 1, localhost:50004 (corresponding to the IP address and communication port of target smart contract A), localhost:50005 (corresponding to the privacy computing module B of target smart contract B), and localhost:50006 (corresponding to the IP address and communication port of target smart contract C). By following these steps, the internal port generated by the target smart contract is assigned to the privacy computing module, communication port, and IP address corresponding to the target smart contract, enabling fast communication between smart contracts and improving the processing efficiency of privacy services.

[0041] Optionally, in the blockchain-based privacy business processing method provided in the embodiment of the present application, the target smart contract calls the privacy computing module to execute the target privacy business based on the internal port and the business execution order, including: determining the first target smart contract one that executes the target privacy business based on the business execution order; the target smart contract one calls the first privacy computing module corresponding to the target smart contract one to perform computing work and obtain a first computing result; based on the target privacy business ID, the target smart contract one determines the second internal port number corresponding to the second target smart contract two that executes the target privacy business in the target comparison table of the target smart contract one; the first privacy computing module transmits the first computing result to the second internal port of the target smart contract one based on the second internal port number; and sends the first computing result and the target privacy business ID to the communication port of the target smart contract two through the communication port of the target smart contract one.

[0042] Specifically, the order of task execution for the target privacy business ID1 is node A, node B, and node C. That is, the target smart contract A is the first target smart contract one to execute the target privacy business. The target smart contract A calls the privacy computing module A (that is, the first privacy computing module mentioned above) to perform privacy computing and obtains the first computing result; based on the target privacy business ID1, the second internal port number corresponding to the second target smart contract two that executes the target privacy business is obtained by querying the target comparison table A, that is, the second internal port number localhost:50002 corresponding to the target smart contract B; the first computing result is transmitted to the second internal port corresponding to localhost:50002; and then the first computing result and the target privacy business ID1 are sent to the communication port of the target smart contract B through the communication port of the target smart contract A. For example, Figure 3 The privacy business processing flow shown, Figure 3 The 1.1.1 in the above description is the second internal port corresponding to transmitting the first calculation result to localhost:50002. Figure 3 1.1.2 in the preceding text refers to the process described above, where the first computation result and the target privacy service ID 1 are sent to the target privacy service ID 1 via the communication port of target smart contract A. Through these steps, the privacy computing module can collaborate to complete the target privacy service without having to communicate with any external privacy computing modules.

[0043] Optionally, in the blockchain-based privacy business processing method provided in the embodiment of the present application, after sending the first calculation result and the target privacy business ID to the communication port of the target smart contract two through the communication port of the target smart contract one, the method also includes: based on the ID of the target privacy business, the target smart contract two determines the first internal port number corresponding to the second privacy computing module through the target comparison table of the target smart contract two, wherein the second privacy computing module is the privacy computing module corresponding to the target smart contract two; based on the first internal port number, the target smart contract two transmits the first calculation result to the first internal port of the target smart contract two; the second privacy computing module obtains the first calculation result, and performs the calculation work to obtain the second calculation result; continue to execute based on the target privacy business ID, the target smart contract two determines the second internal port number corresponding to the next target smart contract that executes the target privacy business through the target comparison table of the target smart contract two, until the target privacy business is executed.

[0044] Specifically, after the target smart contract B receives the first calculation result and the target privacy business ID1, the target smart contract B queries the target comparison table B according to the target privacy business ID1 to obtain the first internal port number corresponding to the privacy computing module B of the target smart contract B (that is, the above-mentioned second privacy computing module), that is, localhost:50005. The target smart contract B sends the first calculation result to the first internal port corresponding to localhost:50005. The privacy computing module B obtains the first calculation result, performs the calculation work, and obtains the second calculation result; then continues to execute according to the target privacy business ID1, the target smart contract B determines the second internal port number corresponding to the next target smart contract (for example, target smart contract C) that executes the target privacy business through the target comparison table B until the target privacy business is executed. For example, Figure 3 1.1.3 corresponds to the target smart contract B sending the first calculation result to the first internal port corresponding to localhost:50005. Through these steps, the first internal port number corresponding to the privacy computing module of the target privacy service is accurately found using the target privacy service ID, avoiding the problem of being unable to identify which privacy service the currently interacted information belongs to due to multiple privacy services using the same port number.

[0045] Optionally, in the blockchain-based privacy business processing method provided in the embodiment of the present application, a unique communication interface is set on each smart contract, wherein the communication interface is used to implement data interaction between smart contracts.

[0046] Specifically, all smart contracts only have a unique external communication interface, and the privacy computing module on the smart contract communicates with the outside world through the unique communication port of the smart contract.

[0047] The blockchain-based privacy service processing method provided in the embodiment of the present application obtains the target privacy service ID, the IP addresses of multiple target smart contracts involved in the target privacy service, the communication port of each target smart contract, and the service execution order of each target smart contract for the target privacy service; based on the target privacy service ID, the internal port generated by the target smart contract is assigned to the privacy computing module, the communication port, and the IP address of the target smart contract corresponding to the target privacy service; based on the internal port and the service execution order, the target smart contract calls the privacy computing module to execute the target privacy service, thereby solving the problem of low privacy service processing efficiency caused by the use of independently deployed blockchain systems and privacy computing systems in related technologies and the cross-system communication method to realize privacy service processing. By assigning the internal port generated by the target smart contract to the privacy computing module, the communication port, and the IP address of the target smart contract corresponding to the target privacy service, and then using the above-mentioned internal port and task execution order, the target smart contract calls the privacy computing module to complete the privacy service, avoiding cross-system communication to complete the privacy service, thereby achieving the effect of improving the processing efficiency of the privacy service.

[0048] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0049] The present application also provides a device for processing a privacy-related service based on blockchain. It should be noted that the device for processing a privacy-related service based on blockchain in the present application can be used to execute the method for processing a privacy-related service based on blockchain provided in the present application.

[0052] The allocation unit 402 is used to allocate the internal port generated by the target smart contract to the privacy computing module corresponding to the target smart contract, the communication port of the target smart contract, and the IP address of the target smart contract based on the target privacy business ID.
