To solve the problem of data authenticity in wireless sensor networks,a data identification and transmission scheme based on digital watermarking was proposed.To distinguish the abnormal data packages from the normal data packages,a digital gene construction method was defined.The digital genes of data sending nodes were constructed using the characteristics of sending data.Digital watermark embedding and detecting algorithms were designed.Data were identified by embedding digital genes into the sending data as digital watermark.The simulation experiments illustrated that the abnormal packages in wireless sensor networks can be effectively identified,such as injected,repeated and random modified packages.Efficient transmission of data was achieved. 无线传感器网络 数字水印 数字基因 识别 wireless sensor network digital watermark digital gene identification 10.14188/j.1671-8836.2010.02.028 TN929.5;TP212.9 国家自然科学基金资助项目（60873199） 2010-02-01 2021-04-01 2 56
