摘要:The swift progression in internet networking services has led to massive growth in various multimediaapplications such as images, audio files, video files etc. This web revolution has made it feasible and simpler to transmitdigital media from one point to another with paramount speed and accuracy. Besides this, it is easier to misuse andexploit the valuable information through hacking at the same time as the ownership and copyright of multimedia filesare not usually protected. Hence, the technology needs to be enhanced to protect data from any unauthorized access. Toprotect intrusion of the intellectual property, digital watermarking becomes very significant. Many effectivewatermarking algorithms have been proposed, however, few algorithms have been proposed for audio watermarking.Digital Watermarking is a technique that allows the copyright protection of multimedia data by insertion of a signature.This paper presents an audio watermarking scheme using multiple bit plan in which a binary image used aswatermark signal is embedded into an audio sample in time domain using bit manipulation techniques simultaneouslyapplied on 1st, 2nd, 3rd and 4th LSB. The watermark is subjected to chaotic scrambling before the process of embedding.Various attacks are also performed on watermarked audio and their impacts on quality of extracted message are alsostudied. This work has been implemented in MATLAB
