Embodiment 1

[0053] Such as figure 1 As shown, the present invention provides a device for authenticating blockchain data using spatiotemporal information, which includes a spatiotemporal blockchain terminal, a spatiotemporal encoding module, a blockchain module, and a server;

[0054] 1. Space-time blockchain terminal

[0055] The spatio-temporal blockchain terminal is a special device used to authenticate the authenticity of the blockchain data source. The spatio-temporal blockchain terminal includes a satellite positioning module, a computing module, and a communication module. The satellite positioning module, computing module, and communication module are electrically connected together. The space-time blockchain terminal is connected to the network of the blockchain module through the communication module, and connected to the network of the space-time encoding module through the communication module.

Embodiment 2

[0078] Such as figure 2 As shown, a method for authenticating blockchain data using spatio-temporal information, the method is based on the spatio-temporal blockchain tag of the spatio-temporal blockchain terminal and the spatio-temporal blockchain tag stored in the blockchain module for cross-validation, the specific steps as follows:

[0079]Step 1: Deploy the space-time encoding module and blockchain module on the server;

[0080] Step 2: Register at the spatio-temporal blockchain terminal;

[0081] The space-time blockchain terminal sends its coordinate position to the space-time encoding module;

[0082] The space-time encoding module generates a string as the unique number (device ID) of the space-time blockchain terminal through the space-time encoding encryption algorithm according to the time and geographic coordinates (longitude, latitude) sent by the space-time blockchain terminal, and the space-time encoding encryption algorithm f 1 , equipment number ID, geogr...

Abstract

The invention discloses a device and method for authenticating block chain data using spatio-temporal information. The device includes a spatio-temporal block chain terminal, a spatio-temporal encoding module, a block chain module and a server; The data generated within a certain period of time can be uploaded to the blockchain system only if it is correct and valid; it eliminates the possibility of counterfeit terminals transmitting data to the blockchain system; The possibility of data transmission in the block chain system, so as to ensure that the source of the data transmitted to the block chain is reliable; the time of the device is guaranteed to be difficult to tamper; the smart contract of the block chain is adopted, which has the characteristics of not being tampered with, and realizes distributed Storage ensures that even if some server node data is lost or damaged, the system can still operate normally.

Description

technical field [0001] The invention relates to a device and method for authenticating block chain data, in particular to a device and method for authenticating block chain data using spatio-temporal information, belonging to the technical fields of satellite positioning and block chain. Background technique [0002] The blockchain has the characteristics of non-tamperable, traceable, decentralized, and distributed bookkeeping of data on the chain, but it cannot solve the reliability and authenticity of the data source, and whether the data source is credible and reliable is the key factor affecting the blockchain. The core issue of blockchain data credibility restricts the application of blockchain technology in real industries. Especially in the application of blockchain technology in supply chain management, trade, cross-border e-commerce, retail and product traceability, the reliability of data sources directly determines the success or failure of blockchain applications...
