摘要

提出了一种基于参数化建模的语音水印算法，并引入了量化保真度准则。水印是通过解决集合隶属度滤波(SMF)问题来实现的，并在信号空间中遵循l/sub /spl infin// fidelity准则。SMF方法在水印鲁棒性和隐写信号保真度之间提供了灵活性。

A quantified fidelity criterion for parameter-embedded watermarking of audio archives

A novel algorithm for speech watermarking through parametric modelling is enhanced by inclusion of a quantified fidelity criterion. Watermarking is effected through solution of a set-membership filtering (SMF) problem, subject to an l/sub /spl infin// fidelity criterion in the signal space. The SMF approach provides flexibility in obtaining watermark solutions that trade-off watermark robustness and stegosignal fidelity.
