Abstract
In this paper, an algorithm is developed to
invisibly watermark a cover object (color image) using
watermark object (iconic image). The algorithm is based on
the distances among the addresses of values of the cover
object. These distances use to make the embedding. The
order of manipulating these distances are specified by the
values of the watermark data which is dealt with serially.
The algorithm serves and achieves self encryption key.
Each watermark object has its unique pattern of distances
at different possible lengths of distance bits. This enhances
the complexity of sequential embedding. The algorithm is
tested using direct and single level and double level of
Two-Dimensional Discrete Wavelet Transform (2D DWT)
embeddings. Two important issues are addressed. Firstly is
to achieve a high Peak Signal to Noise Ratio (PSNR). The
ratio was found to increase with an increasing of distance
bits. Secondly is that the watermarked object retains the
same properties of cover object. The algorithm shows
resisting and withstanding against the most important
attacks. Some of these include the
