提出了基于信源编码技术的无线传感器网络可恢复数据融合隐私保护方案.借助于节点数据相关性对隐私数据进行信源编码,实现了数据隐藏和压缩,对编码后的数据进行了形式转换和拼接,以进行原始数据的恢复,同时利用聚合签名技术鉴别数据的完整性.实验结果表明,该方案能在有效保护数据隐私性、减少数据传输量的基础上,实现对原始感知数据的恢复. This paper proposes a recoverable data fusion privacy protection scheme of wireless sensor network based on source coding technology.With the help of the correlation of node data, it encodes the source data of the private data to realize the data hiding and compression and the format conversion of the encoded data The original data is recovered, and the integrity of the data is identified by using the aggregation signature technology.The experimental results show that the proposed scheme can recover the original perceptual data on the basis of effectively protecting the data privacy and reducing the data transmission.
