A-DWT-HAAR-based-audio-watermarking-algorithm.rar - Audio watermarking is the process of adding the information into audio files in such a way that the hidden information can be used to recognize the owner of the file as well as the quality of the audio signal will not be hampered. Many algorithms for audio watermarking have been proposed and have been used. In this paper, an improved DWT-HAAR based audio watermarking will be introduced.,2015-08-28 10:58:20,下载3次

24-03-01.rar - A Novel Audio Watermarking Algorithm for Copyright Protection of Digital Audio Abstract Digital watermark technology is now drawing attention as a new method of protecting digital content from unauthorized copying. This paper presents a novel audio watermarking algorithm to protect against unauthorized copying of digital audio. The proposed watermarking scheme includes a psychoacoustic model of MPEG audio coding to ensure that the watermarking does not affect the quality of the original sound. After embedding the watermark, our scheme extracts copyright information without access to the original signal by using a whitening procedure for linear prediction filtering before correlation. Experimental results show that our watermarking scheme is robust against common signal processing attacks and it introduces no audible distortion after watermark insertion.,2009-04-28 01:47:16,下载26次
ieeespm00-evaluation.rar - Watermarking schemes evaluation Abstract鈥擠igital watermarking has been presented as a solution to copy protection of multimedia objects and dozens of schemes and algorithms have been proposed. Two main problems seriously darken the future of this technology though. Firstly, the large number of attacks and weaknesses which appear as fast as new algorithms are proposed, emphasizes the limits of this technology and in particu-lar the fact that it may not match users expectations. Secondly, the requirements, tools and methodologies to assess the current technologies are almost non-existent. The lack of benchmarking of current algorithms is bla-tant. This confuses rights holders as well as software and hardware manufacturers and prevents them from using the solution appropriate to their needs. Indeed basing long-lived protection schemes on badly tested watermarking technology does not make sense. ,2009-03-27 17:21:42,下载2次
