| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In mobile environmental sensing, where mobile users sense environmental variables and send data to a server via mobile devices, there is a risk of privacy leakage from sensor readings. Data perturbation, a privacy preserving method, disguises sensor readings on the user side while allowing a server to reconstruct statistical information, such as data distribution, of original data. Data perturbation has a serious problem in that a server cannot calculate the reconstruction accuracy. We previously proposed a method to estimate the reconstruction accuracy using a spatiotemporal model of environmental variables. In this study, we collect air pollution data with our mobile air pollution sensing device. Using the field survey data, we evaluate our methods to estimate the reconstruction accuracy of Negative Surveys, a data perturbation technique. | |
