Embodiment 1
[0071] refer to figure 1 , which shows a schematic flowchart of a specific embodiment of a method for storing Internet of Things data in the embodiment of the present application. like figure 1 As shown, the IoT data storage method of the embodiment of the present application is applied to the IoT device, and the IoT device generates business data, and specifically includes the following steps:
[0072] S101. Digitally sign the service data to obtain a first index of the service data.
[0073] Digital signature has two functions: one is to confirm that the message is indeed signed and sent by the sender, because others cannot fake the sender's signature. Second, the digital signature can determine the integrity of the message. Because the characteristic of the digital signature is that it represents the characteristics of the file, if the file changes, the value of the digital abstract will also change. Different files will get different numeric digests. A digital signatu...
Embodiment 2
[0105] refer to Figure 4 , shows a schematic diagram of the system structure of a specific embodiment of an Internet of Things data storage system in the embodiment of the present application. like Figure 4 As shown, the Internet of Things data storage system of the embodiment of the present application is used to implement the Internet of Things data storage method of some embodiments of the present application, including the Internet of Things database and the block chain node; the block chain node is used for the Internet of Things device The first index of the business data sent is encapsulated into a block, and the first index and the second index of the block are sent to the IoT database. The first index is the digital signature of the business data; the IoT database is used to store IoT devices The business data and the first index sent, and the first index and the second index sent by the blockchain node.
[0106] The IoT device connects to the IoT data storage sys...
Embodiment 3
[0110] refer to Figure 5 , which shows a schematic flow chart of a specific embodiment of an Internet of Things data query method in the embodiment of the present application. like Figure 5 As shown, the Internet of Things data query method of the embodiment of the present application is used to query the data stored in the Internet of Things data storage system of some embodiments of the present application, including the following specific steps:
[0111] S501. Acquire a first query request, where the first query request includes a first index of service data sent by the IoT device, and the first index is a digital signature of the service data.
[0112] The service client initiates a first query request, that is, a service data query request, and the request includes the first index of the service data sent by the IoT device. The business client can be a web browser, a software client, or a mobile APP. The IoT data storage system acquires the first query request, parse...
