Recently, almost all data have been stored and managed by digital types because of development of IT infrastructure. Digital data has the advantage of huge data that can be stored in very small space. However, there is a risk that a large amount of data can be leaked if disk which stored digital data is stolen or lost. Currently, digital data is protected by encryption method to prevent data leaking. However, the encryption method is not enough to protect data because the performance of attack system is higher and the attack methods are various. Therefore, there is a need for a new advanced data protection method. There have been a variety of research methods such as Cloud Shredder which is to maintain local storage and cloud storage for solving this problem. In this paper, we identify the problem of the existing method and propose an advanced method of digital data protection to solve that problem
