Advantages And Disadvantages Of Steganography

What are the advantage and disadvantage of Steganography?

Steganography is an approach that simplify hiding of a message that is to be maintain hugger-mugger inside other message. This result is the secrecy of the hidden message itself. Steganography approach can be used to images, a video file or an audio file.

The use of steganography such equally watermarking which hides copyright data inside a watermark by overlaying document not hands invented by the naked eye. This avoids fraudulent actions and provides copyright secured media more protection.

Reward of Steganography

The reward of steganography is as follows −

The advantage of steganography is that messages practice not send consideration to themselves. Conspicuously detectable encrypted message no matter how tough volition stimulate suspicion, and may in themselves be compromising in countries where encryption is illegitimate.
In steganography, cryptography secures the contents of a bulletin, steganography can be said to secure both messages and connecting parties.
This approach featured security, capacity, and robustness, the three needed element of steganography that creates it beneficial in hidden exchange of data through text files and creating cloak-and-dagger communication.
There are some important files carrying confidential data can exist in the server in and encrypted form and No intruder can receive some beneficial data from the initial file during transmit.
With the demand of Steganography Corporation government and law enforcement agencies tin can connect privately.
The major objective of steganography is to connect privately in a completely imperceptible aspect and to prevent drawing incertitude to the transmission of a subconscious information. It is not to maintain others from understanding the subconscious information, but information technology is to maintain others from thinking that the data even exists. If a steganography approach generates someone to suspect the carrier medium, thus the method has unsuccessful.
The advantage of steganography is that information technology can be generally used to secretly send messages without the case of the manual being found. By using encryption, information technology can recognize the sender and the receiver.
Steganography has a double component of protection such as first, the file itself is secret and second, the data in it is encoded.

Disadvantage of Steganography

The disadvantage of Steganography is as follows −

At that place are large number of information, huge file size, therefore someone tin suspect about information technology.
If this approach is gone in the incorrect easily such equally hackers, terrorist, criminals so this tin can be very much disquisitional.
Steganography is not without its disadvantages. However, these can be rectified and once information technology is performed and it can strengthen the element of steganography.
Nearly data hiding approach take advantage of human perceptual deficiency, but they have deficiency of their ain. However, these can be independently rectified.
The major disadvantage of steganography is that, unlike cryptography, it needed a lot of overhead to hide associatively few bits of data. Because the steganographic system is found, it is rendered useless. Nonetheless, it fares no worse than cryptography and is still the preferred medium.
