Neste estudo, propomos uma arquitetura completa baseada em técnicas de marcas d'água digitais para resolver a questão da proteção de direitos autorais e autenticação de conteúdos digitais. Aplicamos marcas d'água visíveis e semifrágeis como marcas d'água duplas, onde a marca d'água visível é usada para estabelecer a proteção de direitos autorais e a marca d'água semifrágil autentica e verifica a integridade da imagem com marca d'água. A fim de obter o melhor equilíbrio entre a energia de incorporação da marca d'água e a translucidez perceptiva para a marca d'água visível, os coeficientes compostos usando características globais e locais das imagens hospedeiras e da marca d'água no domínio da transformada wavelet discreta (DWT) são considerados com o Sistema de Visão Humana (HVS). Para alcançar a redução ideal de ruído dos limites de visibilidade para HVS no domínio DWT, é aplicada a função sensível ao contraste (CSF) e a função visível ao ruído (NVF) do modelo perceptivo que caracteriza as propriedades globais e locais da imagem e identifica textura e regiões de borda para determinar a localização ideal e a força da marca d'água no estágio de incorporação da marca d'água. Além disso, os pesos perceptivos de acordo com as amplitudes da função básica dos coeficientes DWT são ajustados para a melhor qualidade de translucidez perceptiva no projeto do algoritmo de marca d'água proposto. Além disso, a marca d'água semifrágil pode detectar e localizar ataques maliciosos de maneira eficaz, mas tolerar modificações leves, como compactação JPEG e ruído gaussiano branco aditivo de canal (AWGN). A partir dos resultados experimentais, nossa técnica proposta não apenas melhora os valores PSNR e a qualidade visual do que outros algoritmos, mas também preserva a visibilidade da marca d’água visível sob vários processamentos de sinal e ataques avançados de recuperação de imagem.

Abstract: In this study, we propose a complete architecture based on digital watermarking techniques to solve the issue of copyright protection and authentication for digital contents. We apply visible and semi-fragile watermarks as dual watermarks where visible watermarking is used to establish the copyright protection and semi-fragile watermarking authenticates and verifies the integrity of the watermarked image. In order to get the best tradeoff between the embedding energy of watermark and the perceptual translucence for visible watermark, the composite coefficients using global and local characteristics of the host and watermark images in the discrete wavelet transform (DWT) domain is considered with Human Vision System (HVS) models. To achieve the optimum noise reduction of the visibility thresholds for HVS in DWT domain, the contrast-sensitive function (CSF) and noise visible function (NVF) of perceptual model is applied which characterizes the global and local image properties and identifies texture and edge regions to determine the optimal watermark locations and strength at the watermark embedding stage. In addition, the perceptual weights according to the basis function amplitudes of DWT coefficients is fine tuned for the best quality of perceptual translucence in the design of the proposed watermarking algorithm. Furthermore, the semi-fragile watermark can detect and localize malicious attack effectively yet tolerate mild modifications such as JPEG compression and channel additive white Gaussian noise (AWGN). From the experimental results, our proposed technique not only improves the PSNR values and visual quality than other algorithms but also preserves the visibility of the watermark visible under various signal processing and advanced image recovery attacks.
