摘　　要：数字水印技术具有鲁棒性、透明性、复杂性等特性,大部分文献对水印评估的阐述都是集中在鲁棒性上,实际上复杂性评估在数字水印评估领域也是非常重要的。因此,主要是针对数字音频水印算法嵌入函数的复杂性进行评估。给出了基本方案评估的概念,选取了两种典型的音频水印算法,应用此方案评估标准对算法进行评估,并同时论述了应用到基本方案上的嵌入参数和音频检验集。给出了两种算法复杂性评估的结果并将结果进行比较。Robustness, transparency, complexity and so on are the characteristics of digital watermarking technique, Evaluation of watermark concentrates on the robustness, In fact complexity evaluation is also all-important in the digital watermarking evaluation do- main, Therefore, the evaluation of the complexity of the embedding function of digital audio watermarking algorithms is expounded mainly, The concept of basic profile evaluation is proposed, And two typical selected watermarking algorithms are evaluated applying the basic profile evaluation benchmarking, simultaneously the embedding parameters and audio test sets are presented, . Finally, the evaluation results of the algorithms and compared the results are presented.
