Abstract

The invention relates to the technical field of data supervision, in particular to a construction engineering witness sampling data supervision method and system based on the Internet of things. The method comprises the steps of constructing a three-level blockchain architecture for data uplink, setting a processor level authority, checking a content matching link based on the input of the Internet of things, touching a voice print, a tablet and a positioned authentication instruction, identifying whether the level authority accords with the checking link, checking multiple identity authentication if the level authority accords with the checking link, and checking the link authority in cooperation with other link contracts if the level authority does not accord with the checking link, wherein the contract authority comprises a dynamic geofence and a time window. According to the invention, the physical isolation of sensitive service data on the storage level is realized through the three-level block chain architecture, the three-weight networking sensing and forced verification are combined, meanwhile, the access authority is decoupled from the static identity attribute and is converted into the dynamic situation condition which must meet the intersection of a specific time window and the geofence, and the accurate control of authority management is realized.
