A Blockchain-Based Incentive Mechanism for Crowdsensing Applications to Preserve Privacy

In order to efficiently gather vast amounts of sensing data, crowdsensing apps make use of the widespread smartphone user base. A highly competent user’s participation is necessary to ensure the accuracy of sensing data. These knowledgeable users must be sufficiently rewarded for making up for their resource usage to encourage participation. A “trustworthy” centre raises security and privacy concerns, although the available incentive methods mostly focus on the honesty of the process. In this research, we provide a blockchain incentive mechanism for crowdsourcing apps that protects user privacy and uses a cryptocurrency based on blockchains as a safe reward method. High-quality contributors will be paid for their contributions, which are reflected in transaction blocks. According to the standards for evaluating sensor data released by the miners, they will confirm the transaction. It is suggested to employ a node authenticity checking plan to accomplish k- unsigned confidentiality since transaction information might reveal users' personal information. Our incentive mechanism’s viability and security are demonstrated through theoretical analysis and simulated trials.
