| Popis: | In recent years, many studies have been carried out about information security and watermarking. The main idea of this proposed method is to implement a invisible binary watermarking application based on Discrete Cosine Transform (DCT) and skewness thresholding. Thanks to the use of skewness values, distribution properties of DCT coefficients in blocks can be identified for robust watermarking process. If the distribution is symmetrical or ideal distribution, the DCT blocks of image is used for watermarking process, otherwise it is not used. Thus the deterioration of the image will be reduced and the recovery process of watermark will become easier. |
