Problems solved by technology

[0003] However, due to the limited ability of IoT devices to process data, their internal energy storage devices cannot meet the large power consumption. Therefore, IoT devices are greatly limited in the process of signing or encrypting data.
Secondly, in the process of data transmission in the Internet of Things, there will also be human tampering or destruction, and the tampered data cannot be found in time, and the subsequent analysis of the wrong data will certainly not get accurate analysis results

Embodiment 1

[0035] figure 1 It is a flowchart of a method for processing IoT data provided by Embodiment 1 of the present invention. This embodiment provides a method for processing Internet of Things data, which can be executed by a first Internet of Things device in an Internet of Things system, and can be implemented by means of software and / or hardware. Such as figure 1 As shown, the processing method of the Internet of Things data provided by this embodiment includes:

[0036] Step 101, the first IoT device acquires a data identifier corresponding to the collected IoT data.

[0037] Before this step is executed, the first IoT device collects IoT data, and then preprocesses the collected IoT data, for example, encapsulating and digitally signing the IoT data.

[0038] The data identifier corresponds to the collected IoT data, and a certain algorithm can be used to calculate the IoT data to obtain a data identifier corresponding to the IoT data one-to-one. For example: use the hash...

Embodiment 2

[0060] In this embodiment, on the basis of the foregoing embodiments, a further improvement is made to the method for processing data of the Internet of Things. The method can be executed by the first IoT device in the IoT system, and can be realized by means of software and / or hardware.

[0061] In the technical solution provided by Embodiment 1 above, the first IoT device used to collect IoT data is a legal device on the network. If the Internet of Things data collected by illegal Internet of Things devices that are not on the Internet needs to be stored in the database, a network access request needs to be made in advance, and steps 102 to 102 in Embodiment 1 can only be executed after being linked to the Internet of Things and becoming a legal Internet of Things device. 104. In this embodiment, "on the network" does not refer to a structural line connection, but refers to whether it is in a working state together with other IoT devices.

Embodiment 3

[0076] image 3 It is a flowchart of a method for processing Internet of Things data provided by Embodiment 3 of the present invention. This embodiment provides a method for processing Internet of Things data, which can be executed by a second Internet of Things device in an Internet of Things system, and can be implemented by means of software and / or hardware. Such as image 3 As shown, the processing method of the Internet of Things data provided by this embodiment includes:

[0077] Step 201. The second IoT device receives the identity verification request message sent by the first IoT device. The identity verification request message includes the identity verification information of the first IoT device and the corresponding information of the IoT data collected by the first IoT device. data identifier.

[0078] For the identity verification information of the first IoT device, reference may be made to Embodiment 1, and for the data identifier corresponding to the IoT d...

Abstract

The invention provides an Internet of Things data processing method and device, and an Internet of Things system the method. The method comprises the following steps of acquiring a data identifier corresponding to collected Internet of Things data, wherein the Internet of Things data is collected by a first Internet of Things device; sending an identity verification request message containing identity verification information of the first Internet of Things device and the data identifier to each second Internet of Things device in the Internet of Things in order to enable each second internetof things device to verify the identity verification information according to the respective corresponding block chain, wherein the block chain comprises identity verification information of the legalInternet of Things devices in the Internet of Things; when identity verification passing response messages exceeding a preset proportion are received, generating a new block comprising the data identifier in the block chain corresponding to the first Internet of Things device; and writing the Internet of Things data, the data identifier and the block number of the new block into a database. According to the Internet of Things data processing method and device, and the Internet of Things system, the authenticity and the reliability of the Internet of Things data can be improved.

Description

technical field [0001] The present invention relates to Internet of Things data processing technology, in particular to a processing method, device and Internet of Things system for Internet of Things data. Background technique [0002] During the working process of the IoT device, the collected IoT data needs to be stored in the database, so as to facilitate subsequent analysis of the stored IoT data. In order to prevent IoT data from being tampered with during transmission, IoT devices protect IoT data through digital watermarks, digital signatures, etc. after data collection, or digitally encrypt the collected original data. It can be seen that the confidentiality and privacy of IoT data are improved. [0003] However, due to the limited ability of IoT devices to process data, their internal energy storage devices cannot meet the large power consumption. Therefore, IoT devices are greatly limited in the process of signing or encrypting data. . Secondly, in the process ...
