What is Stenography
Hiding the image or data inside the original information or encrypted information to ensure higher security the process called steganography is developed.
Coveless Stenography
In the proposed system, design of two level image based
plain coverless stenography is being implemented. The proposed system uses
the DWT in a iterative fashion, in which the input image is filtered into
2-level transform, a secret image is hided inside the original image, the
advantage of the proposed system is the encrypted image resembles like the
original image which will not show the hided secret light weight encryption
strategy. The receiver with the same secret image as key with 2-level
decryption transform of I-DWT reproduce the original info.
What we hide
In stenography, normally image , text data, numbers, binary patterns can be hidden . Sometimes in few applications a voice data can also be hided inside the pixels
How secure the System is
The stenography system is tend to be more secure since the there is a strong interconnected link which is understandable by the source and target system only. The intermediate hackers tend to fail attaining the hidden info using simple techniques.
