Audio Watermarking Algorithm Implementation using Patchwork Technique

In a previous couple of years, the web innovation has been doing the advancement of extensive network facilities and digital data communication. Because of this information is exchanged from one device to another device in the form of audio, text, video, images and so forth. The essential documentations like property papers, military records, restorative reports, multimedia data or any personal documents can be sent from one device to another over the web. With the expanding use of computerised data and audio, the security of licensed innovation rights creation has turned into an important issue. Advanced watermarking is currently drawing consideration as a technique for shielding interactive media content from unapproved duplicating. This paper proposed audio watermarking algorithm implemented on Raspberry pi 3 using patchwork, least significant bit and base64 encoding techniques. Experimental results show that the proposed algorithm is superior regarding perceptual quality, security, and robustness.
