PPDC: A Privacy-Preserving Distinct Counting Scheme for Mobile Sensing
2019
Applied Sciences
Mobile sensing mines group information through sensing and aggregating users' data. Among major mobile sensing applications, the distinct counting problem aiming to find the number of distinct elements in a data stream with repeated elements, is extremely important for avoiding waste of resources. Besides, the privacy protection of users is also a critical issue for aggregation security. However, it is a challenge to meet these two requirements simultaneously since normal privacy-preserving
