Database Steganography: Hiding Complete Database In Another Database.

Abstract

Data security is one of the most critical and an uttermost challenge in the digital world. Confidentiality, availability and integrity of data are demanded in every operation performed on data security. The data security in databases is also as important.This paper has presents techniques for the data that can be implemented to immunize and reinforcement databases, and presents a new secure database system based on steganography that provides more confidentiality, authentication, and integrity during access of secrete data. The proposed database system uses steganography technique to hide a database records inside another database records, and allows the authorized user to create tables and records which are hidden from unauthorized users. The proposed system attempts to use the properties of the table file structure in a cover-database, and uses an embedded hidden database with hidden database management system to manage the hidden database. It can store and manage a large amount of data easily.
