In this paper, we present several novel mechanisms for effective encoding and detection of direct-sequence spread-spectrum watermarks in audio signals. The developed techniques aim at i) improving detection convergence and robustness, ii) improving watermark imperceptiveness, iii) preventing desynchronization attacks, iv) alleviating estimation/removal …

KIROVSKI AND MALVAR: SPREAD-SPECTRUM WATERMARKING OF AUDIO SIGNALS 1021 In order to investigate the security of SS WMs, we explore the robustness of such a technology with respect to watermark estimation attacks [2]. To launch that attack, an adversary is assumed to know all the details of the WM codec, except the hidden secret.
A Novel Spread Spectrum Digital Audio Watermarking …
http://jacn.net/papers/71-S039.pdf
In this paper, a frame based audio watermarking scheme using spread spectrum technique in time domain is proposed. The algorithm consists of two procedures; watermarking . embedding procedure and watermarking extraction . procedure. respectively. The watermarked image is M×N pixels. The audio that watermark is embedded is a wav file.

Abstract. This chapter is a comprehensive presentation of spread spectrum-based digital audio watermarking methods. The problem is viewed as the realization of a basic communications system, where the host signal presents the available channel and the watermark presents the transmitted information that needs to survive and be recovered in conditions that …

(HAS). Among all watermarking technique, spread spectrum techniques are widely used as audio watermarking because of their robustness and imperceptiveness of watermarking. The proposed technique is based upon the False positive and False negative probability. False negative probability is a probability of non detection of watermark. Whereas, the false positive

The main aims of the watermarking system can be split into three parts : un-detect ability (inaudibility), capacity (data rate) and robustness, as show in Fig. 1 [2].In audio watermarking technique audio is used as a digital host signal to hide the watermarks (private data). One of the robust techniques in watermarking is a spread spectrum (SS).
