Abstract

본 발명의 비밀보호기능을 구비한 데이타 기록/재생 시스템은 기준패스워드를 이용하여 비밀유지가 필요한 데이타를 암호화한 다음 저장하며, 데이타재생시에는 사용자가 입력하는 패스워드와 기준패스워드가 일치하면 암호화된 데이타를 해독하여 원래의 데이타로 재생함으로써 데이타 사용권한이 있는 취급인가자만이 비밀유지가 필요한 데이타를 사용하도록 한다. 또한, 데이타를 암호화하여 저장하였기 때문에 일반적인 데이타재생수단으로는 올바른 재생데이타를 얻지 못하게 함으로써 데이타 비밀보호기능을 보다 강화할 수 있는 효과가 있다.The data recording / reproducing system with a secret protection function of the present invention encrypts and stores the data that requires confidentiality using the reference password, and during data reproduction, encrypts the encrypted data if the password entered by the user matches the reference password. By decrypting and reproducing the original data, only authorized personnel with data usage rights should use confidential data. In addition, since the data is encrypted and stored, the data secret protection function can be further strengthened by preventing the normal data reproducing means from obtaining correct reproduction data.
