Provided are an apparatus and method for blocking objectionable multimedia based on skin color and face information. The apparatus for blocking objectionable multimedia can block objectionable multimedia by obtaining skin color and face information from multimedia learning data and analyzing it to generate features that may express the objectionability, for example, the presence of a person, a body shape, and the degree of nudity; generating objectionability classification model through statistical analysis and machine learning on the features; and determining the objectionability of newly input multimedia based on the objectionability classification model.

Provided is an obscene content analysis apparatus and method. The obscene content analysis apparatus includes a content input unit that receives content, an input data buffering unit that buffers the received content, wherein buffering is performed on content corresponding to a length of a previously set analysis section or a length longer than the analysis section, an obscenity analysis determining unit that determines whether or not the analysis section of audio data extracted from the buffered content is obscene by using a previously generated audio-based obscenity determining model and marks the analysis section with an obscenity mark when the analysis section is determined as obscene, a reproduction data buffering unit that accumulates and stores content in which obscenity has been determined by the obscenity analysis determining unit, and a content reproducing unit that reproduces the content while blocking the analysis section marked with the obscenity mark.

Provided are an apparatus and method for blocking an objectionable image on the basis of multimodal and multiscale features. The apparatus includes a multiscale feature analyzer for analyzing multimodal information extracted from image training data to generate multiscale objectionable and non-objectionable features, an objectionability classification model generator for compiling statistics on the generated objectionable and non-objectionable features and performing machine learning to generate multi-level objectionability classification models, an objectionability determiner for analyzing multimodal information extracted from image data input for objectionability determination to extract at least one of multiscale features of the input image, and comparing the extracted feature with at least one of the multi-level objectionability classification models to determine objectionability of the image, and an objectionable image blocker for blocking the input image when it is determined that the image is objectionable.

An apparatus and method for determining a characteristic of a motion picture. The method includes dividing the motion picture into video clips and video segments of each video clip, extracting video features from each segment, determining whether or not the respective video features have a targeted characteristic according to respective predetermined references using classifiers based on the respective features and generating determination result values, statistically combining the determination result values indicating whether or not the respective video features have the targeted characteristic according to the segments to generate first combination values, statistically combining the first combination values according to the video clips to generate second combination values, statistically combining all the second combination values to generate a final combination value, and finally determining whether or not the motion picture has the targeted characteristic using the final combination value according to a predefined final point of reference.

Provided are an apparatus and method for detecting illegal motion picture data. The apparatus includes a key frame extractor for extracting a plurality of key frames from motion picture data, a characteristic value file generator for detecting characteristic values of the extracted key frames and generating a characteristic value file, and an illegality determiner for measuring degree of similarity between a previously stored learning model file and the characteristic value file and determining whether or not the motion picture data is legal according to the degree of similarity.

The present invention discloses a system and method for providing a safety content service. The system for providing the safety content service includes a first mobile terminal which extracts meta information of new content when the new content is generated, a server which receives the meta information of the new content from the first mobile terminal, analyzes whether the content is harmful based on a file name and a hash value of the content contained in the meta information, and outputs an analysis result, and a second mobile terminal which receives the analysis result from the server. According to the present invention, it is possible to provide a service which can prevent children and teenagers from being exposed to harmful contents through mobile terminals such as smart phones such that the children and teenagers can safely use multimedia content.

A user terminal and a method of managing user information are provided. The method includes issuing a request for issuance of a certificate for a user to a certification authority; generating a document including at least part of user information using a certificate issued by the certification authority; and issuing a subscription request to a desired web service provider by providing the document including the at least part of the user information to the desired web service provider. Therefore, it is possible to strengthen the user's right to self-determination and control over the exposure and use of his or her personal information. In addition, it is possible to improve the reliability of user information provided to each website by the user.

An anonymous authentication-based private information management (PIM) system and method are provided. The PIM method includes receiving an anonymous certificate not including user information from an anonymous certification authority; generating an anonymous document including the anonymous certificate and some of the user information; and providing the anonymous document to a web service provider so as to be authenticated and thus provided with a web service by the web service provider. Thus, only a minimum of user information may be provided to the web service provider. In addition, it is possible to strengthen a user's right to self-determination and control over the exposure and use of his or her personal information by allowing a user to manage his or her own personal information or entrusting the PIM server to manage user information. Moreover, it is possible to protect the privacy of a user by preventing the exposure of user information.
