Description: In addition, a data hiding technique for high-quality video is presented, where both the audio and chrominance information is hidden in the luminance video frames. Security and synchronization benefits are guaranteed, along with a 9:1 or higher bitrate reduction, for efficient data retrieval and reconstruction.Finally, with respect to the copyright protection issue of multimedia signals, an efficient detection scheme is proposed, where a fused correlation detection process is applied on noisy interpolated versions of the originally watermarked image. The overall detection performance is shown to be significantly enhanced, by a rate greater than 15%.Data hiding has lately emerged as an effective technology aimed at a wide range of applications, beyond conventional hiding of secret information for secure communications.In this thesis, a compressive data hiding technique for multimodal biometric recognition is introduced, for dealing with the constraints of the smartcard/mobile technology. Bitrate improvements of up to 22.5% were achieved.
