Abstract: Abstract In the Internet of Things architecture, the distributed management structure of the data center-micro data center (MDC)-intelligent terminals is the foundation for intelligent terminals accessing, real-time data interaction and data release. It is necessary to perform security level detection before intelligent terminals accessing to the MDCs, which can facilitate MDCs to understand the ability to resist malicious attacks and realize reasonable use of terminals in different security levels. However, the dataset of security levels will be stored in MDCs and transferred as terminals removed. Therefore, an expedite privacy protection method for this dataset is required. This paper studies the privacy protection schemes based on differential privacy (DP) protection and proposes a level-proportion-based differential privacy protection method, utilizing the security level and the level proportion of the intelligent terminals as the parameters to apply DP protection with different intensities, so that the statistical properties of the dataset will not be destroyed. Simulation results show that our method can discriminatively implement DP protection for intelligent terminals with different levels. Moreover, it can hold the statistical properties of the dataset for further utilization.
