A new implementation of trellis coded quantization based data hiding
This paper discusses the construction and implementation problem of trellis coded quantization (TCQ) based data hiding. We explore the robustness and distortion of data hiding by ...

Non-uniform quantizer design for image data hiding
Most quantizer based data hiding schemes use uniform quantizer, which is not optimal if the host signal is not uniformly distributed. In this paper, we design a quantizer that is ...

Rotation and cropping resilient data hiding with zernike moments
Most digital data hiding schemes are sensitive to simple geometric attacks namely rotation, cropping, and scaling. Of these, rotational attacks possess the capability to not only ...

An audio spread-spectrum data hiding system with an informed embedding strategy adapted to a Wiener filtering based receiver
A particular application of audio data hiding systems and watermarking systems consists of using the audio signal as a transmission channel for binary information. The system shou...
