Abstract: The existing Reversible Data Hiding(RDH) schemes for the authentication of Wireless Sensor Network(WSN) have some disadvantages, for example, the watermarking cannot be embedded totally. Aiming at these disadvantages, this paper proposes an improved RDH scheme. This scheme divides dynamically the generator group using the synchronization point and the length controlling threshold, and generates the carrier group by the embedded authentication information capacity and the embedding strategy. In terms of the data types of WSN, a new method to predict the data element and a new prediction-error expansion equation are designed. Finally, the authentication information is embedded and extracted by using the RDH algorithm based on the prediction-error expansion. Experimental results and analyses demonstrate the proposed method has better performance on watermarking embedding and group division than the existing RDH schemes and traditional schemes.

摘要: 目前已有的用于无线传感网络数据认证的可逆信息隐藏方案存在水印信息不能完全嵌入等问题。提出了一种改进的可逆信息隐藏方案。该方案采用同步点和长度控制阈值来动态划分生成分组,并依据嵌入认证信息量及嵌入策略来确定载体分组。根据无线传感网络认证的数据类型,设计了新的数据项预测方法及预测误差扩展公式。基于预测误差扩展的可逆信息隐藏算法完成认证信息的嵌入和提取。实验结果和分析表明同已有可逆信息隐藏方案及传统认证方案相比,提出方案在水印嵌入、分组划分等方面具有更好的性能。
