APLIKASI WATERMARKING DENGAN ALGORITMA AES UNTUK PEMBERIAN DATA HAK CIPTA PADA FILE AUDIO

Abstract

Watermarking audio files has  recently become the  attention  focus. This is primarily due to faster data
transmission rates on the Internet, which has allowed the often illegal proliferation of digital audio files.
Watermarking may give the ability to enforce copyright protection of digital audio files products. The difficulties
in watermarking audio lie in both the desire to preserve file quality and the need for the watermark to remain
intact after a number of possibly damaging file operations. This  topic discusses about watermarking on audio
file with AES (Advanced Encryption Standard) – Rinjdael algorithms with embedding procedure and extraction
to purpose protection Watermarking method to used embedding process and extraction is low bit coding method.
None of the transformations to and from frequency domain are performed either in embedding or extraction part
of the proposed scheme.  Testing  process done using 5 ways such as  suitability of process and data, audio
quality, audio size  and the last is data robustness, those result showed  that  embedded watermark introduces
uncertainly and the embedded watermark into audio signal very is difficult to be detected by human auditory
system.
