Description

Technical Field

The present invention relates to the field of computer technologies, and in particular, to a data processing method and apparatus, and an apparatus for data processing.

Background

An IoT (internet of things) edge computing device is a core device applied to a distributed computing architecture. In the distributed computing architecture, the edge nodes access the distributed computing system through the IoT edge computing device, and the operations of the application programs, data and services are transferred from the network center node to the edge nodes on the network logic for processing. The IoT edge computing device is closer to the ue device, so that the data processing and transmission speed can be increased and the delay can be reduced. Under the structure, the analysis of the data and the generation of knowledge are closer to the source of the data, so that the data processing method is more suitable for processing large data.

However, when private data of a user is shared among IoT edge computing devices, private data leakage is easily generated. Moreover, because the edge nodes and the distributed computing system and the edge nodes are not trusted with each other, only small-scale data sharing or no data sharing is performed, a data island is formed, and the requirement of processing large data cannot be met.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Method embodiment

Referring to fig. 1, a flowchart illustrating steps of an embodiment of a data processing method according to the present invention is shown, where the method is applied to a first edge computing device, and specifically may include the following steps:

step 101, determining metadata corresponding to ciphertext data required by a ciphertext computing task.

And 102, sending the metadata to a cloud management node to acquire positioning information corresponding to the ciphertext data returned by the cloud management node according to the metadata.

And 103, acquiring the ciphertext data from the second edge computing device corresponding to the positioning information.

And step 104, sending the ciphertext computing task and the ciphertext data to a computing node so that the computing node executes the ciphertext computing task by using the ciphertext data.

The metadata corresponding to the ciphertext data comprises at least one of a data type, a data tag and a feature description of the ciphertext data.

The data type may be determined according to a storage type of the data, and for example, the data type may include Integer (Integer type), Long (Long Integer type), Single (Single precision floating point type), Double (Double precision floating point type), and Currency (Currency type) among Numeric data types. The data type may also be determined according to a classification standard set by a user in an actual application process, for example, the data type may be classified according to an application scenario, and the data type may include production data, security data, traffic data, and the like. The embodiment of the present invention is not particularly limited.

The data tags are used for marking the ciphertext data, and each piece of ciphertext data corresponds to one data tag. For example, for traffic data, whether the vehicle is overspeed or not may be determined according to the running speed of the vehicle, and "overspeed or not" is a data tag corresponding to the running speed of the vehicle, and "overspeed is represented by 0 and" overspeed "may be represented by 1. The data tag may also be a unique code of the data, for example, the storage address of the ciphertext data may be used as the data tag. As long as the identifier can mark the ciphertext data and facilitate classification and search of the ciphertext data, the identifier may be used as a data tag of the ciphertext data, and the embodiment of the present invention is not particularly limited.

The feature description is used to summarize data features of the ciphertext data, for example, for traffic data of a vehicle, a driving speed may be taken as a feature description of the vehicle, such as "70 km/h". As long as the information of the data characteristics of the ciphertext data can be summarized, the information can be used as the characteristic description of the ciphertext data.

After the first edge device determines the ciphertext calculation task, metadata of the required ciphertext data can be determined according to the ciphertext calculation task, so that the corresponding ciphertext data can be searched according to the metadata. For example, for a ciphertext computing task "search all cars with a speed per hour greater than 70 km within a distance range of 2 km", it may be determined that the metadata of the ciphertext data required by the ciphertext computing task includes a data type "traffic data of a car", and a feature description "speed per hour greater than 70 km within a range of 2 km", so as to further determine that the ciphertext data including the metadata is the ciphertext data required by the ciphertext computing task.

In an embodiment of the present invention, the first edge computing device may be a data consumer of the ciphertext data, and the second edge computing device may be a data provider of the ciphertext data. The computing node executes a ciphertext computing task on the received ciphertext data based on the multi-party secure computing protocol to generate a computing result, and feeds the result back to the first edge computing device which sends the ciphertext computing task. The cloud management node is used for managing, controlling and coordinating the first edge computing device, the second edge computing device and the computing nodes, and enabling the first edge computing device, the second edge computing device and the computing nodes to complete ciphertext computing tasks through cooperation. The first edge computing device, the second edge computing device, the computing nodes and the cloud management node form an edge computing cooperative network together, and the data processing method provided by the embodiment of the invention is executed to realize data sharing among the edge computing devices, so that the requirement of big data processing is met.

The specific process of data processing based on the edge computing cooperative network formed by the first edge computing device, the second edge computing device, the computing nodes and the cloud management node in the embodiment of the invention is as follows:

first, the first edge computing device analyzes the ciphertext computing task and determines metadata corresponding to ciphertext data required by the ciphertext computing task. The first edge computing device then sends the determined metadata to the cloud management node. The cloud management node stores metadata of ciphertext data provided by each edge computing device in the collaborative computing network and positioning information of each edge computing device, and the metadata of the ciphertext data provided by each edge computing device corresponds to the positioning information of the edge computing device. The second edge computing device sends the metadata and the positioning information corresponding to the ciphertext data to the cloud management node by sending a ciphertext registration request to the cloud management node, and the ciphertext data is registered at the cloud management node.

And under the condition that the cloud management node receives the metadata sent by the first edge computing device, searching the positioning information of the second edge computing device corresponding to the metadata sent by the first edge computing device according to the corresponding relation between the stored metadata and the positioning information, and feeding back the searched positioning information to the first edge computing device. And after the first edge computing device acquires the positioning information, acquiring ciphertext data from a second edge computing device corresponding to the positioning information. And then sending the ciphertext calculation task and the obtained ciphertext data to the calculation node, and executing the ciphertext calculation task by the calculation node by using the ciphertext data.

Alternatively, a URL (Uniform Resource Locator) of the ciphertext data may be used as the location information of the ciphertext data. The URL typically includes a communication Protocol, an IP (Internet Protocol) address of the second edge computing device where the ciphertext data resides, a path, and a file name of the ciphertext data. After the first edge computing device obtains the URL corresponding to the ciphertext data, the corresponding second edge computing device may be determined according to the IP address in the UPL, a communication connection may be established with the second edge computing device according to a communication protocol in the URL, and the ciphertext data may be obtained from the second edge computing device according to a storage path and a file name of the ciphertext data in the second edge computing device.

In the embodiment of the invention, the second edge computing device stores the ciphertext data in the data storage component of the second edge computing device, the cloud management node only stores the positioning information and the metadata of the ciphertext data, when the first edge computing device needs to acquire the ciphertext data to execute the ciphertext computing task, the positioning information corresponding to the ciphertext data is searched from the cloud management node according to the metadata of the required ciphertext data, then a security channel is established according to the positioning information and the second edge computing device related to the ciphertext computing task, the ciphertext data is acquired, and then the ciphertext data is delivered to the computing node to perform ciphertext computing. In the whole data processing process, the first edge computing device only acquires the ciphertext data required by the ciphertext computing task, and does not relate to any original data in the second edge computing device, so that the privacy and the safety of the data are ensured.

In an optional embodiment of the present invention, before determining metadata corresponding to ciphertext data required by the ciphertext computation task in step 101, the method further includes:

The preset timing refers to meeting a trigger condition for creating a ciphertext calculation task, for example, receiving an information stream sent by another IoT device, or a timer of the first edge calculation device reaching a preset time, and so on. And when the preset time is met, the first edge computing equipment creates a ciphertext computing task according to the received service requirement.

It should be noted that the business requirement received by the first edge computing device may be a business requirement generated by the first edge computing device itself, for example, a certain workflow of the first edge computing device needs to perform the next data processing according to the computation result of the ciphertext computation. The service requirement received by the first edge computing device may also be a ciphertext computing request sent by another IoT device to the first edge computing device, and the first edge computing device needs to obtain a ciphertext computing task and then feed back a ciphertext computing result. In any case, as long as there is a business requirement in the first edge computing device, the first edge computing device may create the ciphertext computing task according to the specific business requirement when the preset time is met.

In an optional embodiment of the present invention, the obtaining, in step 103, the ciphertext data from the second edge computing device corresponding to the positioning information includes:

step S11, establishing a first communication link with the second edge computing device based on the heterogeneous communication protocol.

Step S12, obtaining the ciphertext data from the second edge computing device via the first communication link.

After the first edge computing device acquires the positioning information corresponding to the required ciphertext data from the cloud management node, a first communication link between the second edge computing device corresponding to the positioning information needs to be established according to the positioning information to form a secure channel between the first edge computing device and the second edge computing device, and then the ciphertext data is acquired from the second edge computing device through the first communication link to ensure the transmission security of the ciphertext data.

The heterogeneous communication protocol is a generic term of various different types of communication protocols, and includes but is not limited to BLE (bluetooth low Energy) protocol, NB-IoT (NarrowBand Internet of things) protocol, Sora (Software radio) protocol, Zigbee protocol, Z-Wave protocol, 802.11 protocol, CAN (controllerrane network) protocol, and other commonly used communication protocols.

The IoT edge computing device can establish communication connections with other IoT devices of different communication protocols, receive and fuse data sent by IoT devices of different types of communication protocols. In the embodiment of the present invention, the first edge computing device and the second edge computing device are both IoT edge computing devices, and both have the capability of establishing communication connection with IoT devices of different communication protocols. Therefore, in the embodiment of the present invention, the first communication link between the first edge computing device and the second edge computing device may be established according to a communication protocol of the first edge computing device, and the communication link between the first edge computing device and the second edge computing device may also be established according to a communication protocol of the second edge computing device, which is not limited in the embodiment of the present invention.

In an optional embodiment of the present invention, before the sending 104 the ciphertext computing task and the ciphertext data to the computing node, the method further includes:

step S21, a computing node list is obtained from the cloud management node, where the computing node list is determined by the cloud management node according to resource usage of each computing node, and a computation delay of a computing node in the computing node list is smaller than a preset threshold.

And step S22, determining the computing nodes participating in the ciphertext computing task in the computing node list.

In order to increase the data processing speed and reduce the computation delay, the first edge computing device needs to acquire a low-delay computing node from each computing node as a computing node for executing the ciphertext computing task. Specifically, the cloud management node monitors resource use conditions of each computing node in the edge computing cooperative network, establishes a computing node list according to the resource use conditions of each computing node, for example, establishes a graph model of each computing node based on the resource use conditions of each computing node, calculates a weight value of each graph edge, and determines the computing node list according to the weight value of the graph edge. And the calculation delay of each calculation node in the calculation node list is smaller than a preset threshold value. The first edge computing device acquires the computing node list from the cloud management node by accessing the cloud management node, and determines the computing nodes participating in the ciphertext computing task from the computing node list according to conditions which need to be met by the computing nodes required by the ciphertext computing task.

In an optional embodiment of the invention, the method further comprises:

and step S31, receiving a control instruction aiming at the ciphertext calculation task.

And step S32, responding to the control instruction, and controlling the ciphertext computing task, wherein the control instruction comprises any one of a task starting instruction, a task ending instruction and a task modifying instruction.

In the embodiment of the invention, a workflow management interface can be further arranged on the first edge computing device, and a user can remotely control the ciphertext computing task through the workflow management interface. For example, a user interaction interface is arranged on the first edge computing device to receive control instructions of a user; alternatively, the first edge computing device may establish a communication connection with a user terminal, and the user may send a control instruction for the ciphertext computing task at the terminal, and the terminal transmits the control instruction to the first edge computing device.

The control instruction comprises any one of a task starting instruction, a task ending instruction and a task modifying instruction. After receiving the control instruction for the ciphertext computation task, the first edge computing device controls the ciphertext computation task in response to the received control instruction, for example, starting the ciphertext computation task, suspending the ciphertext computation task, modifying the ciphertext computation task, and the like.

In addition, the user may also monitor the resource occupation situation of the first edge computing device in the data processing process, for example, send a resource report request to the first edge computing device, and request the first edge computing device to report the resource occupation situation and update the resource occupation situation in real time.

In an optional embodiment of the present invention, after the step 104 of sending the ciphertext computing task and the ciphertext data to a computing node, so that the computing node executes the ciphertext computing task by using the ciphertext data, the method further includes:

step S41, establishing a second communication link with the computing node based on the communication protocol supported by the computing node.

And step S42, acquiring a calculation result obtained by the calculation node executing the ciphertext calculation task through the second communication link.

The first edge computing device needs to send the ciphertext computing task and ciphertext data acquired from the second edge computing device to the computing node, and the computing node executes the ciphertext computing task on the ciphertext data to obtain a computing result. The computation results are stored at the computation nodes from which the first edge computing device needs to retrieve the computation results. Specifically, the first edge computing device may establish a second communication link with the computing node based on a communication protocol supported by the computing node, and then obtain a computation result of the ciphertext computing task from the computing node through the second communication link.

In addition, the first edge computing device may establish a second communication link with the computing node after determining the computing node corresponding to the ciphertext computing task, and send the ciphertext computing task and the ciphertext data to the computing node through the second communication link. After the computing node executes the ciphertext computing task, the first edge computing device obtains a computing result corresponding to the ciphertext computing task from the computing node through the second communication link.

In order to better implement the data processing method provided by the embodiment of the present invention, each functional component may be configured for the first edge computing device and the second edge computing device in the edge collaborative network, different functional components correspond to different functions, respectively, and the data processing method provided by the embodiment of the present invention is implemented by the combined action of each functional component. Referring to fig. 2, a diagram of an edge computing collaborative network structure according to an embodiment of the present invention is shown. The second edge computing device is responsible for providing ciphertext data, and the ciphertext data in the second edge computing device may be generated by the second edge computing device itself or collected from other IoT devices. The second edge computing device collects ciphertext data from other IoT devices through the ciphertext data collection component, the ciphertext data collection component can establish communication connection with the IoT devices with different communication protocols, and therefore the second edge computing device can collect data from various IoT devices, for example, the second edge computing device collects ciphertext data from IoT devices such as intelligent traffic devices, intelligent security devices, military devices, intelligent household devices and intelligent medical devices, and application scenarios of the data processing method provided by the application are enriched.

The ciphertext data acquisition component transmits the acquired ciphertext data to the ciphertext data preprocessing component, and the ciphertext data preprocessing component performs operations such as denoising processing, filtering processing, screening processing, normalization processing and the like on the acquired ciphertext data so that the ciphertext data can better meet the data processing requirements. The ciphertext data preprocessing component sends the processed ciphertext data to the ciphertext data registration component, the ciphertext data registration component sends a ciphertext data registration request to the cloud management node, positioning information and metadata corresponding to the ciphertext data are sent to the cloud management node, the cloud management node stores the metadata of the ciphertext data according to the positioning information of the ciphertext data, and the metadata of the ciphertext data correspond to the positioning information of the ciphertext data one to one.

And the task triggering component in the first edge computing device is used for creating a ciphertext computing task according to the received service requirement under the condition of meeting the preset time. The task triggering component can receive information streams sent by other IoT devices and can also set a timer. And when the task triggering component receives the information stream containing the ciphertext computing service requirement sent by other IoT equipment or the timer set by the task triggering component reaches the preset time, creating a ciphertext computing task. The task triggering component sends the created ciphertext computing task to the task executing component, the task executing component analyzes the ciphertext computing task, metadata of ciphertext data are determined, corresponding positioning information is obtained from the cloud management node according to the determined metadata, the ciphertext data are obtained from the second edge computing device according to the positioning information, the ciphertext computing task and the ciphertext data are sent to the computing node, computing results are obtained from the computing node and the like. If the ciphertext computing task is created by the task triggering component according to the information stream sent by the other IoT equipment to the first edge computing equipment, the first edge computing equipment feeds back the obtained computing result to the corresponding IoT equipment through the data output component.

The cloud management node continuously monitors the resource use condition of each computing node in the whole data processing process, determines and updates a computing node list, and the computing delay of each computing node in the computing node list is lower than a preset threshold value. Before sending the ciphertext calculation task and the ciphertext data to the calculation nodes, the first edge calculation device can acquire a calculation node list from the cloud management node through the task execution component, determine the calculation nodes corresponding to the ciphertext calculation task, and then send the ciphertext calculation task and the ciphertext data to the determined calculation nodes.

It should be noted that the functional components shown in fig. 2 are only an exemplary illustration and do not limit the embodiments of the present invention. In practical applications, other functional components may also be adopted, or corresponding service software may be configured on the first edge computing device and the second edge computing device, for example, ciphertext data storage service software, ciphertext computing engine service software, encryption computing task management service software, computing resource registration and discovery service software, data resource registration and discovery service software, configuration management service software, and the like.
