Steganography is the practice of concealing a file, message, or other transmission within another file, message, or transmission. It is used to hide the presence of a hidden message so as to avoid detection or scrutiny.
One of the most common examples of steganography is when someone hides a message or file within an image file. For example, the sender may hide text in an image by changing the color of certain pixels of the image to a specific set of values not visible to the naked eye.
Another commonly used steganographic technique is to embed hidden messages within audio, video, or multimedia files. The sender will employ a specific algorithm to embed the message within the data of the file and make it undetectable once the file is sent.
Finally, the use of white space in communication is also considered a form steganography. This involves the sender leaving gaps between words or letters. This allows the sender to disguise a secret message within the text by leaving gaps that only the recipient will be aware of.
Steganography is becoming increasingly popular among cyber criminals and terrorists as it helps them conceal sensitive data and spread their message across the internet without detection.
