IPC: G06F17/30
Filed: 2000-03-03
Abstract: URI 변환부(302)는 수신부(301)가 수신한 데이터 중의 URI를 고정 길이로 변환한다.  이 고정 길이의 URI는 수신부(301)가 수신한 데이터와 함께 수신 정보 기억부(303)에 기억된다.  한편, URI 입력부(307)로부터 입력되는, 원하는 콘텐츠 데이터의 URI가 URI 변환부(305)에 있어서 고정 길이로 변환된다.  URI 비교부(306)는 수신 정보 기억부(303)에 기억된 고정 길이의 URI와 URI 변환부(305)의 출력을 비교한다.  이러한 비교에 의해 일치가 검출된 때에는, 그 때의 고정 길이의 URI에 대응하는 부정 길이의 URI(수신 데이터 중 URI 및 URI 입력부(307)로부터 입력된 URI)가 비교된다.  이러한 비교에 의해 일치가 검출되었을 때에, 해당 부정 길이의 URI가 부가되어 있는 콘텐츠 데이터가 이용자가 원하는 것이라고 식별된다.
