Internet of Things identity verification method based on block chain

Abstract

The invention belongs to the technical field of Internet of Things identity authentication methods, and particularly relates to an Internet of Things identity verification method based on a block chain. The method comprises the following steps: S1, installing recognition devices in places such as expressways, community entrances and the like where in-and-out personnel information needs to be collected, wherein the recognition devices can comprehensively collect palm prints and fingerprints of the whole hands of in-and-out personnel and then input the palm prints and the fingerprints into a database to be stored; S2, forming a block by taking the city as a unit, setting a sub-database in one block, providing a main database for the province to which the city belongs, and linking the sub-database of each city with the main database through the Internet of Things; the method has the advantages that palm prints and fingerprints of the whole hand of a person are collected; the information input amount is large so that lawbreakers cannot copy and tamper the information, and the recognition devices input the information of the places where the personnel arrive and the places where the personnel pass through and comprehensively summarize the information into a national big database and thus the journey of the personnel is locked.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things identity verification methods, in particular to a block chain-based Internet of Things identity verification method. Background technique [0002] The Internet of Things originated in the media field and is the third revolution of the information technology industry. The Internet of Things refers to the connection of any object with the network through information sensing equipment according to the agreed agreement, and the object exchanges information and communicates through the information transmission medium to realize intelligent identification, positioning, tracking, supervision and other functions. [0003] At present, when entering and exiting residential areas or toll stations at highway intersections, card swiping or mobile phone scanning codes are often used. This has a problem. For example, if the mobile phone is not carried or the card is invalid, identity verification cann...
