Multi-Bits Stego-System For Hiding Text in Multimedia Images Based on User Security Priority

Adnan Abdul-Aziz Gutub, Nouf Al-Juaid


Security system for hiding sensitive text-data on personal computer (PC) is implemented. The system proposes using normal multimedia image based steganography replacing the pixel least significant bits with text to be hidden. The study involved several testing scenarios for possible increase in the capacity and ambiguity within steganography adopting 1, 2, 3 and 4 least significant bits stego-systems choices. The design novelty is in providing full security information to the user to select appropriate cover-image from the PC based on the security priority. The technique allows the PC user to test multi-bits steganography on several images to hide same sensitive texts. Then, the user can prefer one image to be used as cover image based on his selection knowing the capacity and security priority desired. The study proofs the data dependency and its security property by experimenting 35 fixed sizes PC images showing remarkable results.
