Adaptive Quantization Index Modulation Audio Watermarking based on Fuzzy Inference System

Many of the adaptive watermarking schemes reported in the literature consider only local audio signal properties. Many schemes require complex computation along with manual parameter settings. In this paper, we propose a novel, fuzzy, adaptive audio watermarking algorithm based on both global and local audio signal properties. The algorithm performs well for dynamic range of audio signals witho...

Audio Watermarking Based on Wavelet Transform and Quantization Index Modulation

In this paper, we present a technique for embedding digital watermarks into digital audio signals. Watermarking is a technique used to label digital media by hiding copyright or other information in the underlying data. In the case of digital audio, the main constraint is the tradeoff between robustness and imperceptibility, as hearing is one of the most sensitive human senses. In our method, t...

Adaptive Wavelet Quantization Index Modulation Technique for Audio Watermarking

The quantization index modulation (QIM) that is often used in watermarking can provide a tradeoff between robustness and transparency. In this paper, we propose a robust audio watermarking technique which adopts the wavelet QIM method with adaptive step sizes for blind watermark extraction. Since wavelet transform offers both temporal and frequency resolutions, it is suitable for audio signal p...

Oblivious Image-Adaptive Watermarking Using Quantization Index Modulation

This paper proposes a new oblivious imageadaptive watermarking technique which utilizes a visual model in the discrete cosine transform (DCT) domain and is based on quantization index modulation. In this scheme, the image is watermarked by modifying selected DCT coefficients of image blocks under a constraint specified by the visual model. The binary watermark is recovered from the watermarked ...
