Using masking effects for audio data watermarking
 Kabourek, Jiří ; Schimmel, Jiří (referee) ; Zezula, Radek (advisor)
In this work is presented technique for embedding digital watermark in digital audio signals. Digital watermark must be imperceptible and should be robust against attacks and other types of distortion. Algorithm is implemented for embedding digital watermark using technique spread-spectrum and psychoacoustic model ISO-MPEG I layer I. Robustness was tested for filtering signal, MP3 compression and resample method.
