Description
Technical Field
The invention belongs to the technical field of Internet of things, and particularly relates to a terminal equipment-based Internet of things data chaining method and system.
Background
The block chain is a chain formed by blocks. Each block holds certain information, which are linked in a chain according to a respective generated time sequence. This chain is maintained in all servers, and as long as one server can work in the entire system, the entire blockchain is secure. These servers, referred to as nodes in the blockchain system, provide storage space and computational support for the entire blockchain system. If the information in the block chain is to be modified, more than half of the nodes must be authenticated and the information in all the nodes must be modified, and the nodes are usually held in different hands of different subjects, so that the information in the block chain is extremely difficult to tamper with. Compared with the traditional network, the block chain has two core characteristics: firstly, data is difficult to tamper, and secondly, decentralization is performed. Based on the two characteristics, the information recorded by the block chain is more real and reliable, and the problem that people do not trust each other can be solved.
The tracing based on the block chain is realized by using a record mode of block chain decentralization, starting products from information of a raw material supplier, key nodes in the storage and production processes in a factory and detection and inspection information after finished products, generating a unique and encrypted hash value through a hash algorithm, and then performing chain storage. Based on the principle of the block chain, all the uploaded data of the block chain cannot be randomly modified by a third party or any party, and the cost is greatly reduced on the trust level.
One of the targets of product tracing and product source tracing is to know the source condition of a product, and if the data of raw material, processing and quality inspection information at the source has problems, the uplink data cannot be tampered without changing the essence of the product, which is one of the core problems faced by block chain source tracing.
The internet of things equipment can acquire real data of one hand, but due to the consideration of technical difficulty and cost, the data of the internet of things equipment is generally summarized to a third-party IOT platform in the industry, and then the platform carries out data chaining. In this way, both data transmission and data packet uplink have the possibility of being tampered, and the security cannot be guaranteed.
