Abstract : Data hiding consists in hiding-embedding binary information within a signal in an imperceptible way.
In this study we pro- pose a high-rate data hiding technique suitable for uncompressed audio signals PCM as used in Audio-CD and .wav format.
This technique is appropriate for non-securitary applications, such as enriched-content applications, that require a large bitrate but no particular robustness to attacks.
The proposed system is based on a quantization technique, the Quantization Index Modulation QIM applied on the Integer Modified Discrete Cosine Transform Int- MDCT coefficients of the signal and guided by a PsychoAcoustic Model PAM.
This technique enables embedding bitrates up to 300 kbps per channel, outperforming a previous version based on regular MDCT.
