A técnica da marca d'água digital é uma das formas de resolver a titularidade dos direitos autorais e verificar a originalidade dos conteúdos digitais (por exemplo, documentos de texto, áudio, imagens estáticas, vídeo, etc.). Neste artigo, obtivemos robustez global e erro mínimo através do uso de marca d'água baseada em quadro e incluindo coeficientes DC e AC da transformada DCT, que estendeu o método convencional de marca d'água com robustez e erro local através do uso apenas de coeficientes baseados em bloco e/ou AC. Como resultado, a alta robustez e qualidade do nosso método foram comprovadas por diversos ataques, como compressão de imagem com perdas, filtragem linear, ruído aditivo, dimensionamento, corte e assim por diante. As marcas d'água incorporadas por nosso método sobrevivem à maioria das compactações JPEG.

Abstract: The technique of the digital watermarking is one of the ways to resolve copyright ownership and verify originality of digital contents (e.g. text documents, audio, still images, video, etc.). In this paper, we obtained global robustness and minimal error through using frame based watermarking and including DC and AC coefficients of DCT transform, which extended conventional watermarking method having local robustness and error through using block based and/or AC coefficients only. As a result, the high robustness and quality of our method were proved by several attacks such as lossy image compression, linear filtering, additive noise, scaling, cropping and so on. Watermarks embedded by our method are survived most of JPEG compressions.
