A High-Rate Data Hiding Technique for Uncompressed Audio Signals

Document Thumbnail

Injecting auxiliary data into a digitized audio stream has been used in watermarking technology that is intended to create copy protection and rights tracking. This application requires robustness and defense against attacks. There are however nonsecure applications that use auxiliary data to enrich the program content, and bit rate is far more important than robustness. The proposed application, using uncompressed PCM audio signals, applies the Quantization Index Modulation technique on the (Integer) Modified Discrete Cosine Transform (MDCT) coefficients of the signal. To achieve inaudibility of the injected information, a psychoacoustic model is used at the embedding stage to exploit the properties of the human auditory system.
