Embodiment

[0069] Example: Urban Noise Perception

[0070] 1. Publish perception tasks

[0071] The structure of the task announcement is shown in Table 1, and the syntax format of the transaction task is as follows, where In-script means input and Out-script means output:

[0072] Task_Claim: Perception task issued by the Server. "in T y "Represents the last task block T linked in y .

[0073] In-script: Sign the released task for Server; is the user u performing the perception task unknown The data quality of ; n is the number of users participating in the perception task; r is the basic remuneration; Cryptographically signed user data

[0074]Out-script: authenticate user u unknown sensory data; verify user identity.

[0075] Value: The deposit M coins given by the server.

[0076] Time-lock: Task deadline.

[0077] The perception task is released by the perception platform Server. Here we take the city noise map perception NoiseTube as an example. The server gives t...

Abstract

The invention relates to a block chain-based security incentive method and system in a crowd sensing application. In this method, the client and the server conduct transactions as the transaction parties of the block chain, including the following steps: 1) the server issues a sensing task to the client; 2) after the client executes and completes the sensing task, uploads the sensing data to the server; 3) ) The miners in the blockchain verify the quality of the perceived data and send it to the server; 4) The server pays the client according to the quality of the perceived data. Further, after obtaining the quality of the perceived data, the miners use the principle of mutual information to quantify the effective contribution of the perceived data quality, and send it to the server, and then the server gives the client corresponding rewards according to the effective contribution. The present invention adopts a secure distributed architecture of the block chain to realize security incentives in the application of group intelligence sensing, which can effectively prevent collusion attacks initiated by the sensing platform, and overcome the security risks faced by trusted third parties.

Description

technical field [0001] The invention belongs to the technical field of crowdsensing privacy protection, and specifically proposes a crowdsensing-based block chain privacy protection incentive method and system for crowdsensing user privacy information protection and perception data verification. Background technique [0002] Crowdsmart sensing refers to the technology that large-scale users collect and share sensing data through mobile terminals with perception and computing capabilities, measure, analyze and estimate the data, and then extract phenomena or information related to public interests. A perceptual network model such as figure 1 shown. Crowdsensing is a combination of the Internet of Things and crowdsourcing. With the development of "Internet +" and the popularization of smart terminals such as smart phones, Pads, and wristbands, crowdsensing is used in environmental pollution quality monitoring, environmental noise maps, and real-time traffic. It has been wide...
