Abstract -
Image Steganography is the process of hiding a secret
image inside a cover image file to produce a fused image called
stego image, so that the secret image cannot be recognized or
recovered by unauthorized recipients. But in the process of
Steganography, the cover image undergoes changes in several
image parameters e.g. HSV (Hue-Saturation-Value), color, hue,
brightness, saturation, quality, etc. The changes in HSV value
depends majorly on the color changes. These changes can
considerably distort the cover image to the extent where it may
defy the purpose of the whole process which is to conceal
information without raising suspicions. The present paper tries
to analyze the effect of Steganography process on the cover
image and study the various differences between the cover image
before and after the process. The various histograms of different
image parameters are also discussed. After that, performance is
measured in terms of PSNR and mean deviation to study the
amount of deterioration caused by Steganography process.
