Abstract: 생체 데이터를 이용한 사용자 인증 장치 및 방법이 개시된다. 특징 벡터 추출부는 인증자로부터 생체 특성을 나타내는 인증 데이터 및 식별코드를 입력받아 인증 데이터를 구성하는 복수의 프레임 중에서 서로 겹치는 부분이 없도록 선택된 테스트 프레임들 각각으로부터 특징 벡터를 추출한다. 인증값 산출부는 추출된 특징 벡터들을 기초로 가우시안 모델의 확률 밀도 함수의 유사도 비에 의해 얻어지는 인증값을 산출한다. 인증부는 사전에 설정된 제1기준값 및 상기 제1기준값보다 작은 값을 가지는 제2기준값이 복수의 사용자 각각의 식별코드에 대응하여 저장된 저장부로부터 입력된 식별번호에 대응하는 제1기준값 및 제2기준값을 독출하고, 인증값이 입력된 식별코드에 대응하는 제1기준값보다 크면 인증자를 정당한 사용자로 인증하고, 인증값이 입력된 식별코드에 대응하는 제2기준값보다 작으면 인증자를 사칭자로 결정하여 인증을 거절한다. 제어부는 인증값이 제1기준값과 제2기준값의 사이값인 경우에는 복수의 프레임 중에서 테스트 프레임들을 제외한 프레임들을 순차적으로 테스트 프레임에 추가시켜 특징 벡터의 추출 및 인증값의 산출 과정이 반복 수행되도록 한다. 본 발명에 따르면, 계산량을 감소시켜 처리 속도를 증가시킴과 동시에 사용자 인증의 정확성도 향상시킬 수 있으므로 모바일 기기에서 우수한 성능을 보이는 사용자 인증 시스템을 구현할 수 있다.

Abstract: A converting method for providing PC, PDA, and mobile Web services by using a DIDL(Digital Item Declaration Language) based-on MPEG21 framework is provided to offer a Web page service to various kinds of terminals regardless of a markup kind. A method of converting an existing content into a content serviceable in a mobile by using a DIDL. A mobuilder(4) edits existing Web contents(5) and creates a DIDL file. When a terminal(1) receives a request, a call manger(2) requests a conversion to a description converter(3). The description converter creates a markup suitable for information of a terminal requested according the DIDL. In the description conversion, a markup suitable for each terminal is created according to information extracted during parsing. The created markup is provided to the mobile through the call manager.

Abstract: A multi-level caching scheme for minimizing a response time of a wireless Web service in a mobile service is provided to reduce a standby time of a terminal by minimizing the number of conversions of a mark-up language. A multi-level caching scheme for minimizing a response time of a wireless Web service in a mobile service includes a content cache(10) and a description cache. The content cache stores and manages contents converted to minimizing conversion of a mark-up language serviceable on a browser of a terminal during a mobile terminal requests a service for a specific content. The description cache(20) can create and research for a new content by the use of a content creator(2) in case that a content does not exist within the content cache. A calling manger(1) provides a service by searching for a content requested from the terminal in the content cache after receiving a service request from the mobile terminal and analyzing terminal information from a mobile terminal DB(50). A description converter(30) creates a content by the use of a DIDL(40) which is a medium language in which mobile content information is recorded and the mobile terminal information.

Abstract: A mobile content providing method and a mobile center used for the same are provided to minimize a response time of a mobile web service by pre-serving optimum one of selected mobile contents to a mobile terminal. If receiving a service request signal from a mobile terminal, a pre-service unit of a mobile center searches whether mobile contents corresponding to terminal QoS(Quality of Service) information of the connected mobile terminal are present in a content cache(S10,S11) If so, the pre-service unit transmits the searched corresponding mobile contents to the mobile terminal in response to the service request signal(S20). If not so, the pre-service unit extracts content QoS information for each mobile content stored in the content cache and computes content similarity for each mobile content(S12). Based on the computed content similarity, the pre-service unit determines whether similar mobile content is present in the mobile contents stored in the content cache(S13). If so, the pre-service unit selects optimum mobile contents having content similarity of a preset level for the connection mobile terminal among the similar mobile contents(S14). The optimum mobile content is transmitted to the mobile terminal in response to the service request signal(S15).
