What are the applications and limitations of steganography?
Steganography is applicable to, but not limited to, the following areas.
- Confidential communication and secret data storing.
- Protection of data alteration.
- Access control system for digital content distribution.
- Media Database systems.
Which of the following is not the applications of steganography?
Which of the following is not a steganography tool? Explanation: ReaperExploit is not a steganography tool that permits security through obscurity. Xaio steganography, image steganography, Steghide etc are examples of such tools.
What are the 5 types of steganography?
Depending on the nature of the cover object(actual object in which secret data is embedded), steganography can be divided into five types:
- Text Steganography.
- Image Steganography.
- Video Steganography.
- Audio Steganography.
- Network Steganography.
What are the advantages of steganography?
a. The advantage of steganography, over cryptography alone, is that messages do not attract attention to themselves. Plainly visible encrypted messages—no matter how unbreakable—will arouse suspicion, and may in themselves be incriminating in countries where encryption is illegal.
Why is this type of steganography useful?
Steganography is the art of hiding a message. The purpose of steganography is to hide a message from a someone you don’t want to see it. Steganography works by changing bits of useless or bot used data in regular computer files (such as graphics, sound, text, HTML) with bits of different, invisible information.
What is steganography and its types and uses?
Steganography is a technique of hiding communication by concealing the secret message into a fake message. The term Steganography has Greek influences which means “covered writing”. Secret Key Steganography takes a cover message and embeds the secret message inside of it by using a secret key (stego-key).
How is image steganography done?
In image steganography, a message is embedded into an image by altering the values of some pixels, which are chosen by an encryption algorithm. The recipient of the image must be aware of the same algorithm in order to know which pixels he or she must select to extract the message.
What are the advantages and disadvantages of using steganography?
Conclusions
| Technique | Advantages | Disadvantages |
|---|---|---|
| High Frequency Domain Encoding | None | Image is distorted. Message easily lost if picture subject to compression such as JPEG. |
What is steganography image?
Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video.
What are the benefits of steganography?
The advantage of steganography is that it can be used to secretly transmit messages without the fact of the transmission being discovered. Often, using encryption might identify the sender or receiver as somebody with something to hide.
What are the applications of steganography?

What is the difference between original and modified steganography?
The original and modified messages are explicitly expected to look different. While in image steganography, the objective is to deceptively hide a message within another original message and thereby, modifying it. The modified message is expected to look very similar to the original message.
What is the difference between cryptography and steganography?
In summary, cryptography hides the meaning of the data, while steganography hides the existence of the data. Although they are different techniques, they might as well be used in combination, in the same instance, to get the best of both worlds. Also Read: What is Image Recognition?
