In mobile crowd sensing tasks, providing incentives with privacy protection is an effective way to motivate users to actively participate in awareness activities. However, existing mobile crowd-aware incentive schemes cannot achieve fair incentives for participants while protecting user privacy. To solve this problem, we propose an RSA-based privacy protection incentive scheme for mobile crowd awareness. Specifically, we use hash encryption technology to protect users’ privacy and use asymmetric RSA encryption method to encrypt sensitive data to ensure that privacy leakage does not occur during data transmission. In addition, we propose an incentive mechanism based on reputation evaluation, analyze participant upload data, and evaluate the data quality of users, and provide participants with corresponding rewards. To verify the effectiveness of our method, it was evaluated in a real dataset. A large number of experimental results show that our method can prevent the privacy leakage of task participants and achieve fair incentives for the distribution of task participants’ rewards.
