The focus of this paper is to have a secure digital media storage technology for creating, preserving, cataloging, indexing and retrieving images, documents and different types of signals in digital media format. The most secure multilayer database system exists with encrypted data files so that an outside source cannot easily access the classified information. The problem with this technique is when an unauthorized client has the knowledge regarding the existence of the secured data in a system; this can make the system vulnerable to alterations, extraction or destroying of the secured data.This paper presents a new conceptual framework of a secure multilayer database system for archiving digital images by using steganographic techniques.The key components of the proposed multilayer system are:1. Integration of security techniques; steganography and cryptography.2. Enhancement of the storage capacity.
