What is steganography and how it works?
Steganography is the art of hiding a message.
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.
This hidden information can be plain text, cipher text, or even images..
What other uses can steganography have for everyday users?
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.
How do you use steganography tools?
Image Steganography You can hide text messages or files inside an image file. Just select the source file in which you want to hide the secret message and then select the file to hide or write the text message to hide. Select the output image location and then click on the start button to start encoding the file.
What is steganography techniques?
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.
Who invented steganography?
Johannes TrithemiusThe first recorded use of the term was in 1499 by Johannes Trithemius in his Steganographia, a treatise on cryptography and steganography, disguised as a book on magic.
Why is steganography better than cryptography?

What are the advantages of steganography?
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.
What makes steganography unique?
Encryption is much simpler and far more data can be encoded in the same space. With techniques such as public-key encryption, you can even communicate without a secure channel. When steganography is used by itself, it’s security through obscurity, which can lead to the secret message being revealed.
Can steganography be detected?
By looking at repetitive patterns, you can detect hidden information in stego images. These repetitive patterns might reveal the identification or signature of a steganography tool or hidden information. Even small distortions can reveal the existence of hidden information.
Is Steganography still used?
Is Steganography still used? Yes, Steganography is still popular among cyber criminals. Recent attacks show that security researchers found a new malware campaign that used WAV audio files to hide their malware. It is believed that the attackers used Steganography to embed the malicious code inside the WAV audio file.
What is steganography and its types?
There can be mainly two types of steganography techniques possible for MMS objects. Fragile steganography comprises of implanting information into a file which is destroyed if the file is modified. Video Technique: Works over video files.
How is steganography used today?
The most common form of steganography used today hides files within image files on a computer. … A similar process can be used to conceal data in sound files since the human ear is limited in its ability to differentiate different, similar frequencies (and in the range of frequencies it can detect).
What is difference between steganography and cryptography?
The steganography and cryptography are the two sides of a coin where the steganography hides the traces of communication while cryptography uses encryption to make the message incomprehensible. … On the other hand, the cryptography alters the standard secret message structure when transferred along the network.
How do I hide messages in photos?

Who uses steganography?
Criminals use steganography to hide information and communicate covertly with other criminals. Their goal is five-fold: scouting the target, scanning it, gaining access, staying undetected, and covering their tracks.
