Flexible Stego-System for Hiding Text in Images of Personal Computers Based on User Security Priority
2014
Flexible security system suitable to hide sensitive text-data on personal computer (PC) is proposed and implemented. The system provides security information to the user to select the cover-image within the PC based on his/her security priority. The technique flexibility allows the user to test several images to hide the same text within. Then, the user chooses one image to be used as cover image based on his selection knowing the security priority needed. The system uses normal image based steganography replacing the pixel least significant bit with text-hidden. The study explores the data dependency and its security effects by experimenting 30 different fixed size images showing interesting attractive results.
