Abstract— In information society, data is become one of the most important part to company or individual. Documented file is one of the forms for storing data on a storage media, especially for use by computers. Thus, documented file protection has become urgent. This paper presents a novel approach to protect documented files from unauthorized access by combining encryption and obfuscation. Encryption is used to protect the confidentiality of document content, and obfuscation provides a way to protect program code by making it unreadable and use to control access. The proposed system protects documented files not only content confidentiality but files access control methods, and can reduce the chance of data leakage at utmost.
