What is a steganographic message?
What is a steganographic message?
Steganography is the practice of hiding a secret message in something that is not secret. But cyber attackers use steganography to do more than share messages. One of the first things I remember doing as a kid was writing secret messages to friends using invisible ink.
What is the hidden message in a steganographic communication?
In steganography, the message is secretly hidden inside a digital file, so there arises no suspicion to the attacker. Steganography does not attempt to scramble the original message but the intent is the same as in cryptography; to protect the original message.
What are the steganographic methods?

What is steganographic data?
Steganography is the technique of hiding secret data within an ordinary, non-secret, file or message in order to avoid detection; the secret data is then extracted at its destination. The use of steganography can be combined with encryption as an extra step for hiding or protecting data.
How do I find hidden text in a picture?
In this case, viewing the text isn’t much of a hassle. Right click on the image, click “Open with” and select “Notepad.” You may need to click “Choose default program” to see Notepad as an option. The text may look like gibberish, but you only need to focus on what’s at the end to view image as text.

What are steganographic techniques and how do they work?

Why is steganographic encoding so difficult to detect?
Stated somewhat more formally, the objective for making steganographic encoding difficult to detect is to ensure that the changes to the carrier (the original signal) because of the injection of the payload (the signal to covertly embed) are visually (and ideally, statistically) negligible.
What is a steganographic media file?
Media files are ideal for steganographic transmission because of their large size. For example, a sender might start with an innocuous image file and adjust the color of every hundredth pixel to correspond to a letter in the alphabet. The change is so subtle that someone who is not specifically looking for it is unlikely to notice the change.
What does steganography mean in Greek?
The word steganography combines the Greek words steganos (στεγᾰνός), meaning “covered or concealed”, and graphe (γραφή) meaning “writing”.
