Embodiment Construction

[0025] Further describe the technical scheme of the present invention below in conjunction with accompanying drawing:

[0026] Step 1: In the whole protection method, the schematic diagram of the analysis among the three roles of the participant, the platform side and the anonymous payment system is as follows figure 1 shown. The main information quadruple of participating workers on the platform is (UserID, Location, Request, Time), where UserID is the unique identification code of the participating worker, Location is the location information in the interaction data, and Time is the information in the perception data. Time record, Request is the interactive information related to the task requirements and the group intelligence platform. Every participant should protect their own ID information. Among the data collected by the Sigma platform, the only relatively critical information is Location, Request, and Time. In order to ensure accurate data quality, the Location and ...

Abstract

The invention provides a crowd-sourcing sensing position privacy protection payment method based on a license chain. A crowd-sourcing sensing platform encrypts core privacy information of participantsby using asymmetric encryption; a public key and a private key are matched to cross the crowd-sourcing platform to transmit data, and the crowd-sourcing platform cannot obtain core privacy information of participants; the crowd-sourcing sensing platform sends the account transfer request to an anonymous payment network CrowdChain for account transfer; the anonymous payment network CrowdChain useszero knowledge proof to ensure complete privacy and anonymity of the transfer transaction, wherein a license chain is used as a carrier of the account transfer system. During data transmission, onlydata necessary for a task is transmitted, and user identity information is not bound. A message transmission mechanism for sending the key message to the third party across the platform is realized. Adigital asset which can be claimed only by using a hash digest of a participant wallet address is generated. According to the payment method, the position privacy of the user is effectively protected.

Description

technical field [0001] The present invention relates to the field of blockchain-based group intelligence perception privacy protection, and in particular to a method for using permission chains for anonymous payment to protect location privacy. Background technique [0002] With the development of wireless communication technologies such as WLAN, 4G / 5G, WiMAX, Bluetooth, and ZigBee, mobile devices are equipped with a variety of embedded sensors with powerful sensing, storage, and processing capabilities. Crowdsensing enables individuals to collect, analyze and share local knowledge through mobile devices. Traditional crowd sensing systems contain three entities: requesters, servers, and workers. The requester publishes the sensing task in the crowd-sensing platform; the server assigns the task and schedules the task; the worker completes the task and sends the relevant data to the requester to obtain the reward. There are two task models for group intelligence sensing, the...
