Steganalysis
Steganalysis is the process of detecting or finding hidden information in digital files like images, videos, and audio files. This technique is used in the field of computer science to uncover concealed messages or data that could pose a security threat.
In simpler terms, sometimes people hide secret things inside ordinary files to keep them safe from others. Steganalysis is the way the computer scientists try to find those hidden things by looking at the files very closely.
For example, someone might hide secret messages inside a picture of a cat. To detect the hidden message, steganalysis techniques would analyze the cat picture to see if there is anything unusual about it. If it finds something unusual or suspicious, it might indicate that there is a hidden message inside the picture.
Steganalysis is important because it can help prevent things like cyber attacks or espionage. It can also be used to detect a file that has been altered in some way, which can help identify forgeries or tampering.
Overall, steganalysis is a clever technique used by computer scientists to uncover secret messages hidden within files, and it plays an important role in keeping digital information secure.
