摘　　要：无线体域网能够借助低能耗高精度传感技术实时采集并分析多种模态的人体健康体征数据,需要在数据传输过程中对关系到个人隐私的健康敏感数据进行保护。针对无线体域网数据融合过程中的隐私保护需求提出一种针对性更强的低能耗数据融合SMART-RR算法,利用人体健康数据存在周期重复性和健康数据冗余特点,提出不等长时间间隔、加入重复性归约因子的数据融合策略。仿真实验表明,SMART-RR算法是一种数据通信量小、高隐私保护性和高精确度的低能耗数据融合隐私保护算法,在面向无线体域网的人体健康体征数据采集分析领域具有一定应用价值。Wireless body sensor network could collect and analyze the multi-modal health data of human body in real time by means of energy-saving and high-accuracy sensor technology,and the sensitive data related to personal privacy should be protected in the process of data transmission. Aiming at the requirement of privacy preserving in the data fusion process of wireless body sensor network,a new SMART-RR algorithm is proposed in this paper,in which an unequal time interval and repetitive data reduction joined factor data fusion strategy is embedded in the algorithm using the characteristics that human health data is cycle repeatability and redundancy. Simulation results show that the SMART-RR is an energy-saving privacy preserving data fusion algorithm with small data communications,high privacy protection and accuracy,and has certain application value in human health signs oriented data acquisition of wireless body sensor network domain.
