Excerpt
Excerpt The primary application of audio watermarking was to preserve copyrights and/or
intellectual properties called DRM (Digital Right Management). However, this technique can be also used to create effective covert channel inside a digital content. Currently there is a number of audio watermarking algorithms available. The most popular methods that can be utilized in real-time communication for VoIP service, include:
LSB (Least Significant Bit), QIM (Quantization Index Modulation), Echo Hiding,
DSSS (Direct Sequence Spread Spectrum), and FHSS (Frequency Hopping Spread
Spectrum) [3] |
