“…Also, the chaotic parameter r∈ [3,4] is a positive constant that usually acknowledged as the biotic potential. The chaotic logistic map is applied to fabricate the chaotic sequence [21]. Furthermore, it is highly sensitive for initial values, and even when the initial conditions are very close, the uncorrelated chaotic sequences are quite large, and the results of the iteration are not similar.…”

Over many years, in order to provide powerful techniques for protecting digital copyrights, digital watermarking techniques have been developed. This research focuses on proposing an efficient blind hybrid digital image watermarking technique based on the transformation of Daubechies wavelet (DW) and Block Bitmap modification (BBM). DW represents an effective multi-determination frequency domain for including the watermarks. The BBM is used to afford an enhanced capability of embedding and minimize distortion. Two layers of security have been added to the proposed technique for protecting digital images from theft by using the logistic chaotic mapping to select the position of the blocks for the embedding process and Lorenz chaotic mapping for scrambling the watermark image. In the experiments, high values of peak signal to noise ratio (PSNR) and structural similarity index (SSIM) are obtained, and all the obtained results illustrate that the presented technique is highly imperceptible, secure, and robust.
