Design of Robust and Secured Digital Audio Watermarking Algorithm Using Hybrid Approach

Abstract

Abstract newlineToday, the use of digital data like image, audio and video is tremendously increasing newlinedue to the advancement in technology and internet revolution. With this advancement, newlineto attain one s ownership and copyrights for the digital data is the biggest challenge. newlineDigital watermarking is one of the techniques to attain one s ownership and newlinecopyrights with security. It is the technique in which, the owner s copy-right newlineinformation can be embedded into the original media either in the form of an image, newlineaudio, text or video. There are two main factors which are to be observed for the newlinedigital audio watermarking to maintain the robustness as well as imperceptibility newlineagainst the piracy, malicious attacks, and various transformation operations. Though, newlinethere are many challenges to achieve these results. As a part of research we have newlinedesigned and implemented Robust and Secured Digital Audio Watermarking newlinealgorithm using hybrid approach with following objectives: newlineand#61623; To implement a robust audio watermarking algorithm which will give the high newlinerobustness against various malicious attacks newlineand#61623; It would also minimize the degradation ration of original content ineffective newlineway. newlineand#61623; To provide the best SNR for provided attacks for all types of audio data. newlineand#61623; The proposed audio watermarking algorithm provides security from the newlineunauthorized people. In addition to that to provide the two factor newlineauthentication one well known method is used in this research work is known newlineas DSSS Encryption. newlineand#61623; It provides the reliability of extracted watermark by measuring BER of newlineoriginal watermark data and the extracted watermark data. newlineand#61623; To make a secured algorithm which can be used in the defense system for newlinetransmitting the hidden message in audio signal. newlineThe proposed audio watermarking technique will improve the robustness, newlineimperceptibility of the embedded information with security and ensures the reliability newlineof abstracted watermark. For Security, in proposed work, synchronized secret key newlineconcept with DSSS encryption algorithm is used to provide the two fa
