Example Embodiment

[0052] Example 1

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

[0054] 1. Space-time blockchain terminal

[0055] The space-time blockchain terminal is a special device used to verify the authenticity of the blockchain data source. The space-time blockchain terminal includes a satellite positioning module, a calculation module, and a communication module. The satellite positioning module, the calculation module and the communication module are electrically connected together. The space-time block chain terminal is connected with the block chain module network through the communication module, and connected with the space-time coding module network through the communication module.

[0057] The satellite positioning module is used to receive...

Example Embodiment

[0077] Example 2

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

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

[0080] Step 2: Register at the space-time blockchain terminal;

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

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

Abstract

The invention discloses equipment and a method for authenticating block chain data by utilizing space-time information. The equipment comprises a space-time block chain terminal, a space-time coding module, a block chain module and a server, according to the invention, it is ensured that only if the data generated in the specified time of the specified position is correct and effective, the data can be uploaded to the block chain system; the possibility that a counterfeit terminal transmits data to the block chain system is avoided; the possibility that fake satellite positioning data generates space-time codes and a space-time block chain label transmits data to a block chain system is avoided, so that the data source transmitted to the block chain is reliable; the time of the equipment is difficult to tamper; a block chain intelligent contract is adopted, the characteristic that the block chain intelligent contract cannot be tampered is achieved, distributed storage is achieved, andit is guaranteed that the system can still operate normally even if part of server node data is lost or damaged.

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...
