SECURITY SERVER USING CASE BASED INFERENCE ENGINE AND STORAGE MEDIUM FOR INSTALLING SECURITY FUNCTION

摘要

The present invention provides a security server, comprising: a transmitting and receiving unit receiving encrypted personal information; a control unit outputting the encrypted personal information to a case based inference engine; a database storing the encrypted personal information into a case database; and the case based inference engine discriminating the encrypted personal information received from the control unit into basic personal information and main personal information, distorting the basic personal information using random numbers, storing the encrypted main personal information into the case database through connection with the basic personal information, and if encrypted search target personal information is inputted, searching for the basic personal information with the highest similarity via similarity search among distorted basic personal information cases from the case database, and checking and decrypting the main personal information connected thereto to output the related personal information into a restoring system. The present invention makes a system apply the outputted personal information to a computer process work, encrypt and distort the main personal information immediately, and store the information at the case database, thereby basically blocking internal and external hacking.;COPYRIGHT KIPO 2017
