Description
  • This article describes a method that enables embedding watermarks into audio signals. The watermark embedding technique is designed such that the embedded watermark does not audibly damage the quality of original data but is simultaneously robust enough as regards the methods of audio signal processing and deliberate attempts focused on removing it. The watermark embedding process uses a pseudorandom generator to define positions in the time-frequency space in which, using a suitable modification of thee magnitude components of the signal, the embedded watermark is encoded in the MCLT (Modulated Complex Lapped Transform) domain. The extraction algorithm of the embedded watermark does not require knowing the original audio data for its working.

  • Tento příspěvek popisuje metodu, která umožňuje vkládat vodoznaky do audio signálů. Vložení vodoznaku je provedeno takovým způsobem, že vložený vodoznak příliš nenarušuje kvalitu původních dat, ale přitom je dostatečně odolný proti běžným metodám zpracování akustických signálů a pokusům záměrně cílených k jeho odstranění. Proces vkládání vodoznaku využívá pseudonáhodného generátoru k určení pozic v časově - frekvenčním prostoru, na kterých se vhodnou modifikací modulových složek signálu v MCLT (Modullated Complex Lapped Transform) oblasti kóduje vkládaný vodoznak. Algoritmus extrakce vloženého vodoznaku nepotřebuje znát ke své funkci původní audio data. (cs)
