Embodiment Construction

[0030] As mentioned earlier, it is difficult to introduce a completely trusted third party in the crowd sensing system, and it cannot guarantee the safety of the crowd sensing process. In order to solve the technical problems of user privacy disclosure and data security in the prior art, in the embodiment of this application, the unique attributes of the blockchain (anonymity, non-tamperable modification, etc.) are used to eliminate security from untrusted third parties. threaten. Resists a variety of malicious attacks, and can also prevent single-point failures. At the same time, a decentralized blockchain structure is used to store users' private data, avoiding user privacy leaks and data loss. At the same time, based on the smart contract concept of the blockchain, as long as the contract trigger conditions are met, the smart contract deployed in the blockchain will be automatically executed to help both the task requester and the worker reach an agreement.

Abstract

The invention relates to the technical field of computers, and concretely relates to a method and a system for mobile crowd sensing, a server and a storage medium. The method comprises the following steps: a task requester publishes a sensing task to a public block chain; a sensing user on the public block chain acquires the sensing task and issues an application request for the sensing task; after the user information of the sensing user on the public block chain passes the verification, the public block chain establishes a contract for the task requester, the sensing task and the sensing user on the public block chain; and after the sensing user on the public block chain uploads sensing data for the sensing task, the task requester pays a reward for the sensing user on the public block chain according to the contract. The technical problems of user privacy leakage and data loss in the prior art are solved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a mobile crowd sensing method, system, server, and storage medium. Background technique [0002] Crowd sensing mines group information by perceiving individual information and reacts to individuals or groups. Crowd intelligence is the cooperation and win-win between individuals and groups. Mobile crowd sensing applications can be roughly divided into three categories: environment, public facilities and society. [0003] In the traditional mobile crowdsensing (Mobile Crowdsensing, MCS), based on the centralized mobile crowdsensing system, it consists of the central server, the task release requester (the person who issues the sensing task) and the worker (the mobile user who participates in the sensing task ), they interact in a centralized structure: task requesters post tasks on the perception platform, and the centralized platform sends tasks to workers accord...
