PATA: A Protocol for Mobile Sensing Privacy-Aware and Trustworthy Data Aggregation

Now days essentiality of the mobile device such as smartphones and tablets, in which having various number of mobile sensing applications are used in different area such as for air pollution monitoring and for healthcare survey. With the increasing capabilities of mobile devices such as smartphones and tablets, there are more and more mobile sensing applications such as air pollution monitoring and healthcare. These applications generally combine the information given by mobile users to show the information about humans activities or surroundings. When the data supplied by mobile users is decent and trustworthy then the mobile sensing works properly. System may be damage if the mobile users act like eavesdropper due to malicious impact and submit forge data. Sometimes, mobile sensing users unable to submit data because of security issue. To overcome on these issues, a new privacy-aware and trustworthy data aggregation protocol for mobile sensing proposed. PATA protocol permits the server to collect the data which is add by mobile users without knowing the data of individual user. At the same time, if malicious users try to submit wrong data, system will be found or the denied aggregation result by the server. In this way, the malicious users effect on the aggregation result is effectively limited. The knowing of wrong data works even if multiple malicious users collude. Security measurement determined that this scheme can give the trustworthy and privacy preserving goals, and implementation of scheme shows that it take low computation cost and low power consumption.
