Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The application may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. The application may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices.
In this application, "module," "system," and the like refer to a related entity, either hardware, a combination of hardware and software, or software in execution, that is applied to a computer. In particular, for example, an element may be, but is not limited to being, a process running on a processor, an object, an executable, a thread of execution, a program, and/or a computer. Also, an application or script running on a server, or a server, may be an element. One or more elements may be in a process and/or thread of execution and an element may be localized on one computer and/or distributed between two or more computers and can be operated by various computer-readable media. The elements may also communicate by way of local and/or remote processes based on a signal having one or more data packets, e.g., from a data packet interacting with another element in a local system, distributed system, and/or across a network in the internet with other systems by way of the signal.
Finally, it should be further noted that the terms "comprises" and "comprising," when used herein, include not only those elements but also other elements not expressly listed or inherent to such processes, methods, articles, or devices. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of another identical element in a process, method, article, or apparatus that comprises the element.
It should be noted that, in the related art, when performing a privacy computation task, a privacy node in a privacy computation network often uses resource or function data in other nodes, and it is necessary to open a network (e.g., a network white list, a firewall white list, etc.) between the privacy nodes and perform direct node data communication. Although the private computing network realizes ' data is not available and visible ', the data of the demanded party still flows out from the node, and the requirement that the original data is not out of the domain ' in a high-privacy data transmission environment is not met.
In view of this, fig. 1 shows a flowchart of an example of a privacy computing method based on a privacy computing node according to an embodiment of the present application.
With respect to the execution subject of the present method embodiment, it may be the first privacy computing node in the privacy computing system. It should be understood that the privacy computing system includes a plurality of privacy computing nodes, and the first privacy computing node may be any node in the system, and should not be limited thereto.
As shown in fig. 1, in S110, when the private computation task exists, a local data source corresponding to the private computation task and required data description information for the second private computation node are determined.
It should be appreciated that in processing a private computing task, a first private computing node would need to use resource data or functional data of other private computing nodes (i.e., a second private computing node). At this time, the first privacy computing node may find a local data source related to the privacy computing task from the local resource library, and parse the node information where the required data resource is located and the related data description.
In S120, a privacy calculation is performed based on the local data source to obtain first encrypted data, and a privacy calculation request is generated according to the demand data description information. Here, the requirement data source information and the feedback data format may be defined in the requirement data description information, so that the data fed back by the second privacy computation node can satisfy the privacy computation requirement of the first privacy computation node.
In S130, the privacy computation request is sent to the platform server, so that the platform server forwards the privacy computation request to the second privacy computation node. Here, traffic transit is performed based on the platform server, so that the second privacy computation node can timely acquire the required data resources.
In S140, second encrypted data fed back by the second private computing node for the requirement data description information is acquired. Here, the second privacy computation node may encrypt the required data resource and feed back the encrypted data.
In some embodiments, the network between the first privacy computing node and the second privacy computing node is interworking, at which time the first privacy computing node may receive the second encrypted data directly from the second privacy computing node. Optionally, the second privacy computing node may send the fed back second encrypted data to the platform server, so that the platform server forwards the second encrypted data to the first privacy computing node.
In S150, privacy calculation is performed based on the first encrypted data and the second encrypted data.
In the embodiment of the application, data transmitted between privacy computing nodes is encrypted, the computing process is based on ciphertext computing, and each node performs isolation computing respectively, so that the security of original data in the nodes is fully guaranteed, and the aim of 'the original data cannot be out of the domain' on the premise of meeting data sharing is fulfilled.
It should be noted that, for different privacy computation service scenarios, different privacy computation operations may be respectively adopted. Specifically, regarding step S150 above, in some embodiments, the first privacy computing node may obtain a service type corresponding to the privacy computing task, and perform privacy computation on the first encrypted data and the second encrypted data based on a privacy computing algorithm corresponding to the service type. Here, the privacy computation algorithm includes one or more of: a privacy intersection algorithm, a covert query algorithm, and a federal learning algorithm.
For example, in the scenario of advertisement delivery, if there is a data set for each of node a and node B when delivering the advertisement for wine, the two data sets are intersected (i.e. privacy intersection) to obtain the customers who may need to buy wine. At this time, the first privacy calculation node may perform intersection calculation on the first encrypted data and the second encrypted data according to a privacy intersection algorithm according to a service requirement. At the moment, the intersection is calculated by using the privacy calculation, only encrypted data flows out of the node, and plaintext data cannot go out, so that 'data cannot go out of the domain' is realized.
In some embodiments, the first encryption algorithm and the second encryption algorithm are determined based on an asymmetric encryption algorithm. Illustratively, when performing the privacy negotiation operation between node a and node B, first node a and node B negotiate a key, and node B cannot solve the resource data of node a encrypted by the key. And vice versa, the node A can not solve the resource data of the node B encrypted by the key, and the security of the original data in the node can be fully guaranteed. For example, in the privacy intersection algorithm, node B encrypts data and sends the encrypted data to node a, and then node a encrypts its own data and compares the two encrypted data to directly find the intersection. The whole process is encrypted, the calculation is also ciphertext calculation, decryption is not needed, and the privacy security of shared data is improved to a great extent.
In some business scenarios, the first privacy computing node is intended to provide a specific business application service to the outside by performing privacy computing tasks. Specifically, after the first privacy computing node performs privacy computation by using first encrypted data and second encrypted data, the first privacy computing node generates an application service interface according to a privacy computation result of the first encrypted data and the second encrypted data, and then the first privacy computing node sends registration configuration information of the application service interface to the platform server, so that the platform server can route a received traffic request for the registered application service interface to the first privacy computing node.
In some embodiments, the platform server may generate corresponding interaction controls for each application service interface, and when a user accesses the platform server, the platform server may generate a traffic request by operating an interested interaction control, and then the platform server may route the generated traffic request to a specific private computing node in the private computing system, thereby implementing external security data transmission service of the private node.
Fig. 2 is a flowchart illustrating an example of a platform server based privacy computation method according to an embodiment of the present application.
As shown in fig. 2, in step 210, a privacy computation request from a first privacy computation node is obtained. Here, the first privacy computing node is an initiator of the privacy computation.
In step 220, the privacy computation request is forwarded to the second privacy computation node, so that the second privacy computation node performs privacy computation based on the required data description information in the privacy computation request to obtain second encrypted data. Here, the second privacy computation node is a partner of the privacy computation. Through the flow transfer of the platform server, the data required by the privacy calculation can be informed to the second privacy calculation node in time, so that the second privacy calculation node carries out encryption calculation on the required data, and the data outflow of a plaintext is avoided.
In step 230, second encrypted data fed back by the second privacy computing node is obtained.
In step 240, the second encrypted data is sent to the first privacy computing node, so that the first privacy computing node performs privacy computation based on the first encrypted data and the second encrypted data, wherein the first encrypted data is obtained by the first privacy computing node performing privacy computation based on a local data source corresponding to the privacy computation task.
In the embodiment of the application, the privacy computing nodes are communicated through the platform server, and data interaction between the isolation nodes is realized. In addition, before the requester initiates formal privacy computation to the partner, the data description required by the requester is transmitted to the partner in advance, and the partner prepares data in advance and encrypts the data, so that the data adopted during node outflow and encryption computation are both ciphertext data, and the secure transmission of the data is realized.
In some examples of embodiments of the present application, each private computing node is configured to have unique node identification information. Furthermore, when forwarding traffic, the platform server may parse target node identification information in the privacy computation request, and forward the privacy computation request to a second privacy computation node according to the target node identification information. Therefore, each privacy computation node corresponds to unique node identification information, and flow forwarding can be accurately completed by analyzing the node identification carried in the flow request, and the flow cannot be forwarded to the wrong flow node.
In some examples of embodiments of the application, the platform server may obtain registration configuration information of an application service interface of the first privacy computing node, the application service interface being generated according to privacy computation results of the first encrypted data and the second encrypted data. Further, the platform server deploys the application service interface according to the registration configuration information, and when a traffic request for the application service interface is detected, the platform server routes the traffic request to the first privacy computing node.
Fig. 3 is a flowchart illustrating an example of a data transmission method based on a private computing network according to an embodiment of the present application.
It should be noted that, in order to meet the requirement of "original data is out of domain, data is not visible", the embodiment of the present application makes improvements to the original private computing system network, including the following: 1) A privatization deployment link: and deploying the private nodes at the data provider, and deploying the data nodes and the computing nodes in the private nodes. The data node provides data access service and accesses data of a data party; the compute nodes provide computing services. 2) Configuring a tenant ID link: a respective tenant ID (also referred to as a node identification) is assigned for each private computing node such that the tenant ID to which the node corresponds is unique. 3) A request forwarding service link: based on a request forwarding service (also called as a platform server), traffic requests can be routed according to tenant IDs, and the fact that various private computing nodes are available and can interact with each other is achieved.
In the privatization deployment link, on the data provider side, a privatization node (also referred to as a privacy computing node) is deployed. The privatization node comprises a computing node and a data node, wherein the privatization data node provides data access service, and the access data can be in a file form, a MySQL form, a Hive form and the like, and can be adapted to various data formats to access data. The privatized computing node provides computing service, accesses data of a system, provides service to the outside, and provides external calling service in the form of API after computing is finished, wherein computing capacity is provided by the privatized deployed computing node through a large amount of encryption computing.
In the process of configuring the tenant ID, a large amount of interaction exists among privacy computing nodes, and the tenant ID is introduced for distinguishing the nodes. One tenant ID corresponds to one privatized node, and the tenant ID is globally unique.
In the request forwarding service link, a large amount of interaction exists among privacy computing nodes, and a request forwarding service is needed for facilitating the interaction. Illustratively, when there are two private computing nodes a and B, and node a wants to request data in node B, node a only needs to construct a request, provide the source tenant ID, the destination tenant ID, and then submit the request to the request forwarding service, so that the result returned by node B can be obtained. Since the tenant ID of each node is unique, the request forwarding service is not forwarded to the wrong node.
Fig. 3 shows a signal interaction flow between privacy computing nodes. The data providing node a, the data providing node B, and the data providing node N are configured with respective tenant IDs, and each tenant ID is unique. After the tenant ID is configured, a privacy calculation service is created at the node A, the service is supposed to only relate to the data of the data side A and the data side B, and the whole process is as follows: the node A takes own data and processes the own data through the own computing node A; after the processing is finished and when the data of the node B is needed, the node A sends a request to the node B through a request forwarding service, and the data encrypted by the node B is taken out through a privacy calculation method. After the encrypted data of the node B is taken, the node A obtains an application service through calculation and provides calling for the outside. Therefore, the data is ciphertext data when flowing out of the node and during encryption calculation, the safety transmission of the data is realized, and the requirement that the data cannot be out of the domain is met.
Note that there are different data services in each private computing node (e.g., nodes a, B, N). When an external user wants to call, the exposed API is requested from the platform, and the API can automatically forward to the corresponding private node through the request forwarding service, so that the external service of the private node is realized.
In the embodiment of the application, through the private deployment and privacy calculation method, the 'original data cannot be out of the domain, data is visible and cannot be used', and the target of data compliance sharing and use is guaranteed.
