The embodiment of the invention provides a data verification method and device for an Internet-of-things system. The Internet-of-things system includes user equipment, an acquisition terminal and a data platform connected through a network. The method includes the following steps: the user equipment obtains a first hash value of a (N-1)th time, first data of an Nth time and a first hash value of the Nth time, wherein N is an integer greater than 0; the user equipment performs hash operation on the first data of the Nth time and the first hash value of the (N-1)th time to obtain a characteristic hash value; the user equipment determines whether the characteristic hash value is consistent with the first hash value of the Nth time; if the characteristic hash value is consistent with the firsthash value of the Nth time, the user equipment obtains a second hash value of the Nth time; and the user equipment determines whether the second hash value of the Nth time is consistent with the first hash value of the Nth time. The data stored in the data platform is prevented from being modified, and the security of the data is improved.
Description
technical field [0001] The present invention relates to the technical field of communication, in particular to a data verification method for an Internet of Things system and a data verification device for an Internet of Things system. Background technique [0002] The existing Internet of Things system is mainly composed of collection equipment and data platforms, which can be connected through mobile networks; among them, the collection equipment can be equipped with various sensors, and further, the collection equipment adopts various encryption, non-encryption The channel reports the sensor data to the data platform, and the data platform stores the sensor data and provides it to other users for reference. [0003] However, in the operation of the data platform, the sensor data uploaded by the collection equipment to the data platform can be artificially modified, for example, the shopping website (data platform) modifies the GPS information of the goods (collection equi...
