Abstract: The present invention relates to an oral health prediction apparatus and method using a machine learning algorithm, which, when a user uploads an oral photo, comprehensively analyzes whether the user has braces, a dental caries state, a prosthesis state, and the like through a photo analysis using the machine learning algorithm, to enable exact prediction of oral health of the user. When a user provides an oral image of the user through a network by using a user terminal and requests an oral health determination result, the present invention analyzes the oral image by using the machine learning algorithm to predict an oral health state, analyzes a dental caries state and a prosthesis state through the analysis of the oral image, predicts the oral health state on the basis of the analyzed dental caries state information or periodontitis state information and prosthesis state information, and provides oral health state prediction information to the user.

Abstract: Provided is a system for exchanging contents between a first DRM apparatus and a second DRM apparatus, wherein each of which belongs to different DRM domain. The first DRM apparatus includes unpackaging means for unpackaging first DRM formatted contents into clear resources, metadata, and rights expression; converting means for converting each of the clear resources, metadata, and rights expression into its own predefined neutral format, respectively; generating means for generating neutral formatted contents by combining the converted resources, metadata, and rights expression; adding predetermined header information thereto; and transmitting means for transmitting the neutral-formatted contents to said second DRM apparatus.

Abstract: It is an object of the present invention to provide a method for synchronizing motions in a cooperative game system in which two or more motions of structures configured by input events are displayed to be integrally and simultaneously implemented in synchronization with a unit time. According to the present invention for achieving the aforementioned object, there is provided a method for synchronizing motions realized in a game system including dance games played through cooperation between players, wherein if, with respect to an event input by one player during any one of unit times when progress is repeated in synchronization with a standard time, another player inputs the same event, a unit motion corresponding to the inputted event is simultaneously represented through the structure during a subsequent unit time.

Abstract: A digital information security system is disclosed. A user application tool installed in a user terminal, creates a unique user key using unique system information of the user terminal. A data storage unit stores user information and digital information. A user management tool installed in a server, receives the unique user key created by the user application tool, stores the received unique user key in the data storage unit as part of the user information, and compares, during user authentication, the stored unique user key with a unique user key provided from the user application tool of a user currently being subjected to authentication.
