ABSTRACT
Data hiding is the process of secretly embedding information inside a data source without changing its perceptual quality or its statistical properties. In this paper we present a new data hiding technique for embedding a high data rate in the transform domain. This technique is suitable for applications such as covert communication and captioning. The technique is based on increasing the number of image transform coefficients used to carry the information by decorrelating the image samples in the spatial domain. The embedding technique does not introduce noticeable changes neither in the perceptual quality nor in the statistical properties of the cover image. Hence, it is considered to be secure.

Lossless data embedding: new paradigm in digital watermarking
One common drawback of virtually all current data embedding methods is the fact that the original image is inevitably distorted due to data embedding itself. This distortion typically cannot be removed completely due to quantization, bit-replacement, or ...
