Abstract

부당한 액세스 코드가 소정 횟수 이상 입력되는 경우에 데이터가 기록된 기록 매체에의 액세스를 금지시키는 데이터 보안 장치가 개시된다.Disclosed is a data security apparatus for prohibiting access to a recording medium on which data is recorded when an invalid access code is input a predetermined number of times or more.

본 발명에 따른 데이터 보안 장치는 데이터 기록 매체를 액세스하고자 하는 사용자에 의해 입력된 액세스 코드와 설정된 키 코드를 비교하여 그 결과에 따라 불일치 혹은 일치 신호를 발생하는 코드 비교부; 상기 코드 비교부에서 발생된 일치 신호에 응답하여 데이터 기록매체를 인에이블시키는 인에이블 처리부; 상기 코드 비교부에서 발생된 불일치 신호의 발생 횟수를 계수하는 불일치 횟수 계수부; 상기 불일치 횟수 계수부의 계수 결과를 소정의 설정된 허용 횟수와 비교하여 일치되는 경우에 방지 신호를 발생하는 비교부; 및 상기 비교부에서 발생된 방지 신호에 응답하여 데이터 기록 매체를 디스에이블시키는 디스에이블 처리부를 포함함을 특징으로 한다.A data security device according to the present invention comprises: a code comparing unit which compares an access code input by a user who wants to access a data recording medium with a set key code and generates an inconsistency or a matching signal according to the result; An enable processing unit for enabling a data recording medium in response to the coincidence signal generated by the code comparing unit; A mismatch count counting unit for counting the number of occurrences of the mismatch signal generated by the code comparing unit; A comparator for comparing the count result of the discrepancy count counter with a predetermined set number of times and generating a prevention signal when the count is matched; And a disable processing unit for disabling the data recording medium in response to the prevention signal generated by the comparing unit.

본 발명에 따른 데이터 보안 장치는 부당한 액세스가 허용 횟수 이상 입력되면 데이터 기록 매체에의 액세스를 봉쇄함으로써 설정된 키 코드의 가능한 조합을 무제한으로 입력하여 시스템을 무력화시키는 시도를 방지하는 효과를 갖는다.The data security device according to the present invention has the effect of preventing attempts to disable the system by restricting access to the data recording medium when an illegal access is input more than the permitted number of times, thereby allowing an unlimited number of possible combinations of the set key codes to be input.
