“…For other methods such as Fourier Transform, Wavelet Transform, Walsh Transform, KL transform and other frequency transform, our design framework provided by this paper can be quickly implemented. What's more, the high-efficiency batch processing capability of the proposed system can extend to other image or video processing applications such as image compression [22] and video digital encryption. Our cloud acceleration method has broad application prospects.…”

Digital watermarking has the properties such as invisibility and anti-aggression, so the digital watermarking technology has been widely used in copyright protection, information hiding. The watermarking technology takes into account the invisibility and robustness of the watermark by controlling the embedding intensity and position of the watermark mainly in the transformation domain. In this paper, discrete cosine transform (DCT) is adopted to transform the given image from spatial domain to frequency domain for adding watermark information. In order to meet the demands of image watermarking batch processing and cloud processing in the future, this paper optimized the DCT algorithm and the data precision, and successfully deployed the designed accelerator kernel on the FPGA cloud platform to speed up the processing of watermarking. The implementation of data processing based on cloud platform is the development trend of big data era. The cloud platform adopted in this paper is based on the OpenCL heterogeneous architecture combining CPU and FPGA. The cloud-based implementation makes digital watermarking application highly extensible, widely shareable, and more secure. The whole system implements a series of complete cloud processes including image decoding, image preprocessing, watermark embedding, and watermarked image encoding. The watermarking algorithm is accelerated by the efficient parallel computing capabilities of FPGA. It can be seen that the result of acceleration is remarkable, providing the state-of-the-art throughput of 1.676 GBps and the highest processing speed of 937 FPS for 800 × 800 sized colorimage.

“…Broadly, watermarking can be divided into two classes: robust and fragile watermarking [22]. Robust watermarks are required to remain in the watermarked image even after it has been manipulated by different attacks whereas the fragile watermarks are designed to be broken easily by image processing operations.…”

Nowadays, with the rapid development of the Internet, the transmission of digital data such as images, videos and texts through the Internet becomes more convenient. Therefore, how to protect the integrity and copyright of digital data has become an urgent issue. This paper presents a watermarking method that based on Discrete Wavelet Transform (DWT), Discrete Cosine Transform (DCT) and Singular Value Decomposition (SVD) in order to protect copyright of digital images. The experimental results show that the quality of watermarked images are maintained good with high robustness against various attacks and watermark can be extracted from embedded image without original image.

Abstract. In recent years, digital watermarking of photo and video materials has become more and more important in connection with the transmission of multimedia data over unsecured communication channels. Digital watermarking allows to reduce the amount of transmitted information and to protect embedded metadata. Improving robustness and security of embedded data increases computational costs, which obstruct usage of digital watermarks in mobile devices. In this research, we propose a number of improvements to the digital watermarking process based on Arnold and discrete wavelet transforms to reduce the computational cost. Considering the watermark as a linear sequence of pixels allows us to speed up its processing. The two-dimensional lookup table allows performing an Arnold transform in constant time regardless of the number of iterations. Number of iteration for each block of watermark is determined using hash function applied to the secret key. Also, the structure of the lookup table is proposed to accelerate the embedding of watermark. This table allows to determine the frequency coefficients for embedding based on the key hash code. Proposed improvements allow to speed up the watermark preparation by an average 14 times and the overall embedding process by 1.22 times for 1920×1080 images.
