While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 is a method for processing device data provided in an embodiment of the present application, which is applied to an interaction platform, and the method includes:
In an embodiment of the application, the interaction platform is a blockchain link point in a blockchain network for coordinating device data transactions between a first blockchain client and a second blockchain client. The first blockchain client refers to an interactive client installed in an electronic device of a device provider, which typically needs to purchase device data generated by the device during daily operations from the device owner. The second blockchain client refers to an interactive client installed in the electronic device of the device owner. Each interactive client belongs to a blockchain node in the blockchain network, the installation package of the interactive client can be pre-stored in each blockchain node of the blockchain network and is stored in a distributed manner by using an IPFS (Inter planar File System), and after an equipment provider and an equipment owner can join the blockchain network, the equipment provider and the equipment owner can download and install the equipment into own electronic equipment from the blockchain network. The block chain network is a decentralized distributed account book database composed of block chain link points, wherein all the block chain link points can communicate with each other to form a peer-to-peer mesh structure, and data generated by one block chain node can be simultaneously transmitted to other block chain link points in the block chain network and can also be inquired and acquired from other block chain nodes. In the embodiment of the present application, the blockchain node refers to a first blockchain client and a second blockchain client participating in the device data transaction and an interaction platform responsible for the coordination between the first blockchain client and the second blockchain client.
The device data requirement information may be input by the device provider through the first blockchain client according to its own requirements, for example: the device comprises basic information of the device such as the name of the device, the manufacturer of the device, the model of the device, the name of the parameter of the device, the operation age of the device and the like, and a time range, a parameter type, a parameter value, an association relation between the parameter and the product percent of pass of the device for generating data in the operation process.
In practical application, a device provider needs to optimize and improve a produced device according to device data generated by the device in the running process, device basic information of a second blockchain client in an interaction platform can be checked through a first blockchain client, the device basic information is uploaded to the interaction platform when a device owner accesses a blockchain network, and the device basic information is also aggregated by the interaction platform and then is checked by the first blockchain client or other blockchain nodes in the blockchain network.

And the second block chain client uploads the equipment data obtained by integrating the equipment owners according to the equipment data demand information to the block chain network for distributed storage. However, since data in the blockchain network is stored in an encrypted manner, if the query is required to be the data identifier, that is, the unique hash value of the data, the second blockchain client generates the data identifier of the device data for keeping when uploading the device data, and other users cannot query the device data from the blockchain network when not obtaining the data identifier, so that the security of device data storage can be ensured.
Referring to fig. 2, a distributed storage method for device data is provided, where the device data corresponds to a unique hash value as a data identifier, and the device data is divided into a plurality of data segments and stored in each blockchain node of a blockchain network.
In practical application, since the device data is replicable, if the device data is directly and completely provided to the first blockchain client for the device provider to view, there may be a case that the device data is copied infinitely without authorization of the device owner, so before the device data is provided to the first blockchain client, desensitization processing can be performed on the device data, so that the device provider can view the desensitized device data through the first blockchain client before the transaction of the device data is completed, the situation of the device data is roughly known, and the security of the device data is also ensured.
