This paper presents a watermarking scheme for copyright protection of digital images. A
binary logo is the copyright label which is embedded in grayscale or color digital images. A
set of integer parameters, selected by the legal owner, controls the watermarking algorithm
via a strongly chaotic (mixing) system. Watermark detection is performed without resorting to
the original image. The embedded binary logo is reconstructed or the statistical detection
certainty is provided indicating the watermark existence. Numerical experiments testify the …
