윈도우 운영체제에서 파일 보안 기능 개발

Abstract

This paper designs file security function on Windows O.S. Whenever you use Windows O.S, you need to protect some file data. This paper designs these security protection functions. This paper proposes two security functions on Windows O.S. One is file security. The other is directory access protection. To check the proposed functions well, I experiment the above functions on the Windows O.S. By this experiment, I confirmed that the proposed function worked well. The Computer is inevitable thing in our life. The most important thing in computer system is file management. It is very important to keep file safe. Safe file management has become important technology as increasing use of computer system. This paper designs file and directory security in Windows O.S. Windows O.S is used in the world-wide computer system. The important files should be kept safe in Windows O.S. This paper designs file and directory protection function in Windows O.S. The function suggested in this paper is composed of the file security and the indicated directory protection. The suggested file security function is storing encrypting file using encryption algorithm so that cannot access it by unpermitted people. The encrypted file is read by decrypting it. This is designed and implemented user friendly interface. This paper experiments encryption and decryption function of the proposed program normally. I experiment also decrypt or not in case of incorrect password. This paper has also directory protection function in Windows O.S. I design directory access control of Windows O.S. The suggested directory access control function protects directory access from unpermitted people by directory access permission. I experiment also the suggested directory access. I confirmed the suggested directory access is working well. This paper is composed of chapter 5. Chapter 2 is related research, Chapter 3 is designed Windows O.S security function. Chapter 4 is experiment and evaluation. Chapter 5 is conclusion.
