Abstract: An apparatus and method for preventing illegitimate distribution of digital contents on Internet obtains a first wavelet image having a user information-embedding region by performing a wavelet transformation (WT). The user information embedding region of the first wavelet image is wavelet-transformed to obtain a second wavelet image composed of a discrete cosine (DC) region and high-frequency regions second wavelet image. A high-frequency components removed image is obtained by removing high-frequency components in the high-frequency regions of the second wavelet image, and subjected to an inverse WT (IWT) to be outputted as an IWT image. A user information embedding unit embeds user information to the IWT image, wherein data of the user information are sequentially embedded to positions where a difference value between the user information embedding region and the new user information embedding region is small, to thereby reset the user information embedding region as the user information.

Abstract: An apparatus and method for embedding and extracting digital watermarks based on wavelets which is robust to external attacks while being capable of minimizing a degradation in picture quality caused by embedding of the watermarks. The embedded watermarks embedded in DC component domains of wavelet-transformed domains can be robust to external attacks such as compression. The high-frequency dependency of pixels in a DC component domain determined as a target domain, in which watermarks are to be embedded, is calculated, in order to embed the watermarks in the target domain in the order of pixels having a higher high-frequency dependency. Accordingly, there is an advantage in that it is possible to minimize a degradation in picture quality caused by the embedding of watermarks in the DC component domain.

Abstract: A system and a method for managing a semantic blog with an ontology are provided to support ontology modeling by checking concepts of various blogs found in the semantic blog and relationship among the concepts, and offer a semantic blog browsing mechanism enabling a user to perform intelligent search for an interested subject with the ontology. A blog server(301) manages and provides blog information to bloggers. A blog ontology modeling module(302) defines an entry used in the blog and the relationship among the entries by using the ontology, and constructs knowledge corresponding to a field of the blog in a visualized environment based on the ontology. An ontology database(309) stores an ontology construction result of the blog ontology modeling module in a database form. A dynamic community generating module(307) presents the relationship among the entries found in the blog by utilizing the ontology construction result as a knowledgebase and generates a community of a user viewpoint by grouping other blogs according to the relationship selected from the user.
