Today, the use of digital data like image, audio and video is tremendously increasing due to the advancement in technology and internet revolution. With this advancement to attain the one’s ownership and copyrights for this digital data is the biggest challenge. Digital watermarking is one of the technique to attain one’s ownership and copyrights with securely. It is the technique in which the owner’s copyright information can be embedded into the original media either in the form of an image, audio, text or video. There are two main factors we need to observe for this digital audio watermarking to maintain the robustness as well as imperceptibility against the piracy, malicious attacks, and various transformation operations. Though there are many challenges to achieve this results, in this paper, our proposed audio watermarking technique is used to improve the robustness, imperceptibility of the embedded information with security. For Security, in our proposed work we are using synchronized secret key concept with DSSS encryption algorithm and two important powerful transformation methods used that are DWT (Discreet Wavelet Transformation) up to 4-level to get lowest frequency sub-band and after that DFT is applied to get lowest frequency from sub-band found by DWT in which the modifications are done and then SVD (Singular value Decomposition)is applied to it, so that original audio file does not have any impact of watermark bits to get the better robustness and imperceptibility.

The 21st century is the digital world, the utilization of digital information like multimedia that contains image, audio and video is massively expanding because of the progression in innovation and web transformation. With this headway to achieve the one's proprietorship and copyrights for this advanced information is the greatest test. Digital watermarking is one of the procedures to accomplish one's proprietorship and copyrights with safely and securely. Digital watermarking is the strategy in which the proprietor's copyright data can be installed into the original media either as an image, audio or video. There are two fundamental components we have to consider for this digital audio watermarking to get the high robustness and also imperceptibility against the piracy, malevolent assaults, and different kind of transformation attacks. Despite the fact that there are numerous difficulties to accomplish these outcomes, in this paper, our proposed audio watermarking system is utilized to enhance the robustness, reliability and imperceptibility of the embedded data with security. For Security, in our proposed work we are utilizing DSSS encryption algorithm and some vital transformation techniques utilized that are DWT (Discreet Wavelet Transformation) up to 4-level to get most reduced frequency sub-band and after that DFT(Discrete Fourier Transform) is applied to get least frequency component from sub-band found by DWT in which the alterations are done and after that SVD (Singular esteem Decomposition)is used to it, so unique audio document does not have any effect of watermark bits to improve robustness and imperceptibility. This algorithm is implemented in MATLAB software that is used for numerical computation and data analysis. The GUI is presented in this paper for audio watermarking with different calculations.
