Esquemas de marcas d’água digitais têm sido discutidos para resolver o problema associado à aplicação de direitos autorais. Anteriormente, propusemos um método usando correlação interbloco de coeficientes DCT. Possui as características de que a marca d’água incorporada pode ser extraída sem a imagem original nem os parâmetros usados no processo de incorporação e que a quantidade de modificação, a força da marca d’água incorporada, depende da característica local de uma imagem. Esse recurso torna difícil para os piratas preverem a posição em que o sinal da marca d'água está incorporado. Neste artigo, propomos um método que pode incorporar/extrair marca d'água em alta velocidade, utilizando este método de marca d'água para formato de arquivo JPEG.

Abstract: Digital watermarking schemes have been discussed to solve the problem associated with copyright enforcement. Previously, we proposed a method using inter-block correlation of DCT coefficients. It has the features that the embedded watermark can be extracted without the original image nor the parameters used in embedding process and that the amount of modification, the strength of embedded watermark, depends on the local feature of an image. This feature makes it difficult for pirate to predict the position in which the watermark signal is embedded. In this paper, we propose a method which can embed/extract watermark with high speed by utilizing this watermarking method for JPEG file format.
