Differential Privacy Preserving Dynamic Data Release Scheme Based on Jensen-Shannon Divergence
文献摘要：
Health monitoring data or the data about infectious diseases such as COVID-19 may need to be constantly updated and dynamically released,but they may contain user's sensitive information.Thus,how to preserve the user's privacy before their release is critically important yet challenging.Differential Privacy(DP)is well-known to provide effective pri-vacy protection,and thus the dynamic DP preserving data release was designed to publish a histogram to meet DP guarantee.Unfortunately,this scheme may result in high cumulative errors and lower the data availability.To address this problem,in this paper,we apply Jensen-Shannon(JS)divergence to design the OPTICS(Ordering Points To Identify The Cluster-ing Structure)scheme.It uses JS divergence to mea-sure the difference between the updated data set at the current release time and private data set at the previ-ous release time.By comparing the difference with a threshold,only when the difference is greater than the threshold,can we apply OPTICS to publish DP pro-tected data sets.Our experimental results show that the absolute errors and average relative errors are sig-nificantly lower than those existing works.
