“…LSB modification scheme is simple and commonly used technique in spatial domain watermarking [5][6] [8]. In this scheme, Least Significant Bit of the original image or also known as cover image pixel {P i }  (0, 255) is replaced with watermark bit {W i }(0, 1).…”

In this research work a novel idea of compressed, encrypted and encoded watermark embedding scheme for digital images is proposed. Initially watermark is compressed using Huffman encoder. Compressed watermark is encrypted using combined binary key sequence {Ki} derived from sequence of logistic map and Lozi map. The compressed and encrypted binary watermark is encoded using (n,1) repetition code. This compressed, encrypted and encoded binary watermark is embedded in alternate locations of cover image pixels using of Least Significant Bit (LSB) and Second Least Significant Bit (SLSB). To study the watermarked image quality, parameters such as Signal to Noise Ratio (SNR) and Mean Square Error (MSE) are used. Also performance of the proposed system is compared with uncompressed, encrypted, encoded watermark embedding scheme. There is a significant improvement in MSE, SNR of watermarked image, when compressed watermark embedding scheme is compared to uncompressed watermark embedding scheme.

“…An ocean of watermarking schemes is mainly divided into two types: (i) Spatial domain and (ii) Transform domain. It is worth mentioning that the least significant bit (LSB) [2] is one of the most representative methods in spatial domain, which embeds the watermark into the cover image by modifying the least significant bit. The transform domain includes discrete cosine transform (DCT) [3], discrete Fourier transform (DFT), and discrete wavelet transform (DWT), etc.…”

“…A spatial domain-based digital watermarking scheme embeds watermark information via controlling the pixel values of the carrier image. The least significant bit (LSB) algorithm [2] is the most widely used technique in spatial domain watermarking. In this method, watermark information is directly embedded into one or multiple bit-planes of images.…”

In watermarking schemes, the discrete wavelet transform (DWT) is broadly used because its frequency component separation is very useful. Moreover, LU decomposition has little influence on the visual quality of the watermark. Hence, in this paper, a novel blind watermark algorithm is presented based on LU transform and DWT for the copyright protection of digital images. In this algorithm, the color host image is first performed with DWT. Then, the horizontal and vertical diagonal high frequency components are extracted from the wavelet domain, and the sub-images are divided into 4×4 non-overlapping image blocks. Next, each sub-block is performed with LU decomposition. Finally, the color image watermark is transformed by Arnold permutation, and then it is inserted into the upper triangular matrix. The experimental results imply that this algorithm has good features of invisibility and it is robust against different attacks to a certain degree, such as contrast adjustment, JPEG compression, salt and pepper noise, cropping, and Gaussian noise.
