Steganology for the Computer Forensics Examiners

It is tough to know intention of the steganography users .So it is difficult for investigators or forensic examiners to detect an image. Examiners need to develop other forensic tools like steganography steganalysis and sterilization for better advancement. As key may or may not use in steganography so it is cheaper in comparison to cryptography. Beside they can be also implemented by any user to preserve the integrity of the message easily since digital signature is not indispensable here.Nowadays organizations based on steganology are concentrated on different untraceable steganographic algorithms. Similarly steganalysis and sterilization tools are used for undetected steganographic algorithms.Image Processing provides several information regarding image or current situations where as steganography (can considered as a chapter of image processing) provide strength of security. Where as sterilization and steganalysis strengthen it.
