“…To evaluate the quality of extracted watermark, the bit-correct ratio (BCR) is adopted to measure the similarity between the original watermark W and the extracted watermarkW . The use of this measure has become common recently [22], as it allows for a more detailed scale of values and is defined as the ratio of correct extracted bits to the total number of embedded bits [22]:…”

This paper presents a new blind and robust image watermarking scheme based on discrete wavelet transform (DWT) and discrete cosine transform (DCT). Two DCT-transformed sub-vectors are used to embed the bits of the watermark sequence in a differential manner. The original sub-vectors are obtained by the sub-sampling of the approximation coefficients of the DWT transform of the host image. During the extraction stage, the simple difference between the corresponding sub-vectors of the watermarked image, gives directly the embedded watermark sequence. Experimental results demonstrate that the proposed technique successfully fulfills the requirement of imperceptibility and provides high robustness against a number of image-processing attacks, such as JPEG compression, noise adding, low-pass filtering, sharpening, and bit-plane removal. Our scheme exhibits also an acceptable to good performance against some geometrical attacks such as resizing and cropping.

“…Huang et al optimized both the watermarked image quality and the robustness of the extracted watermarks by tabu search (TS). This approach overcomes channel impairments while ensuring copyright and ownership protection (Huang et al, 2011). Another approach is singular value decomposition and lifting wavelet decomposition (Loukhaoukha et al, 2014).…”

Recently, two-dimensional (2D) barcodes displayed on mobile phones are becoming used for authentification such as airplane boarding pass and online payment. Digital watermarking is promising technology to detect illegal replication or fabrication of such 2D codes. However, due to geometric distortions and/or interferences between patterns of camera sensors and screen pixels, watermark may not be sufficiently extracted from subbands which are used when embedding the watermark. This paper proposes a two-stage optimization method for watermark embedding and extracting scheme design. The proposed method discriminates frequency subbands between for embedding and extraction, whereas general watermarking schemes extract the watermark from the same subbands as while embedding. To evaluate actual image deterioration by digital-analogue conversion with mobile phone screen and camera, the proposed method uses actual mobile phones to obtain real images of valid and replicated 2D codes. Experimental result have shown that the proposed two-stage optimization of watermark embedding and extracting schemes improved watermark performance for 2D code replication detection.

“…Still, all the data must be encrypted before sending the shares over unsecure channels, which will be time-consuming in encrypting and decrypting. Huang et al [17] and Pan et al [24] proposed algorithms for vector quantization (VQ) based image watermarking with multiple description coding (MDC), which can be used in error-resilient transmission over noisy channels.…”

Image sharing has become a prominent field in large and small networks. However, in order to deliver the shares to their respective shareholders, we need a secure channel to protect the shares from potential attacks by other users on the network. These users can locate the shares and retrieve the image using the Lagrange interpolation method if they are able to locate the minimum required number of shares. This paper proposes a method to protect the privacy and security of the shares when sending them through unsecured channels. The proposed method is divided into three phases. In the first phase, image pixels are changed using the column and row indices, then the shares are created using Shamir's secret sharing (SSS) method. Then a relationship is created between the shares using a linear independence function. In the second phase, the first part of the image is encrypted to hide the solver data. Finally, in the third phase, the data is shared using the SSS method. Participants can retrieve the whole image by applying the reverse order of the proposed method using only the information from the sender through the same channel. The simulation results show that the proposed method is efficient and robust against different types of attacks and can be used to send the shares over unsecured channels.
