Abstract

Abstract: The classical digital watermarking algorithms of LSB in the space field for the certification in the ECG signals is studied.A robust blind adaptive watermarking algorithm is proposed.The algorithm hides the watermark in the non-QRS complex waves.The experiment of embedding and attacking proves that the algorithm can guarantee the transparency and resist LSB attack.And the embedded watermark can be completely extracted.The watermarking algorithm is robust and has better performance for hiding，which can be used for one dimensional signal certification.

摘要： 研究了经典的空域数字水印算法LSB在心电图信号认证中的应用，选择在非QRS复合波内嵌入水印信息，提出了基于LSB的自适应数字盲水印算法。通过嵌入水印后的图像效果和攻击实验证明，这种水印嵌入算法对心电图信号具有良好的视觉效果，可抵抗LSB攻击，鲁棒性强。该算法性能优良，可用于其他一维数字信号认证。
