Mobile sensing system and mobile sensing method for user privacy protection and data reliability

Abstract

The invention discloses a mobile sensing system for user privacy protection and data reliability, and a mobile sensing method thereof. The method comprises the following steps: performing system initialization; registering a mobile user, obtaining a sensing task request token from an administrator; performing anonymous user authentication and task allocation, and returning task authorization / refusal information by a platform; performing anonymous report of user sensing data and trust evaluation, and feeding back certificate information by the platform; performing certificate submission and reward allocation, submitting all certificates by the user and obtaining corresponding rewards; and updating the credibility of the user. According to the mobile sensing method, on the premise of protecting the privacy of the legally participating users, the malicious behaviors of abusing the privacy protection mechanism by malicious users are handled, more participates are activated to submit morereliable sensing data by the reward and credit evaluation mechanism so as to provide a safe, reliable and effective mobile sensing system.

Description

technical field [0001] The invention relates to an Internet of Things application technology, in particular to a mobile sensing system and a mobile sensing method for user privacy protection and data reliability. Background technique [0002] Mobile sensing is a new type of IoT sensing mode that integrates various technologies such as sensors, communication, network fusion, and information processing with mobile users as the main participants. Compared with traditional wireless sensor networks (WSNs), mobile sensing has the advantages of low sensing cost, wide sensing range, and strong flexibility. The network does not need to deploy a large number of static sensor nodes. Various mobile devices, such as smartphones and wearable devices, can use a variety of embedded sensors (such as GPS, accelerometers, and biomedical sensors) to sense the user's own and surrounding environment information anytime, anywhere. And pass it to the perception server through 3G / 4G or WIFI network...

AI Technical Summary

Problems solved by technology

But in general, the existing research is independent, and the inherent contradiction between privacy protection and data reliability makes it difficult to provide a safe, reliable and efficient mobile sensing system.

Simple integration of different technologies cannot effectively solve new problems. For example, using the privacy protection mechanism, malicious users may submit unreliable data anonymously, and some greedy users may anonymously submit perception data multiple times in order to obtain more rewards, etc.
