STEGANOGRAPHY Meaning and
Definition
-
Steganography is a technique of hiding or concealing information within another piece of data, such as text, images, audio, or video files, in a way that does not raise suspicion about the presence of the hidden content. The term "steganography" derives from the Greek words "steganos" meaning covered or hidden, and "graphia" meaning writing.
Steganography aims to ensure that only the sender and intended recipient can decipher the hidden message, while others remain unaware of its existence. It is often used to protect sensitive information, prevent unauthorized access, or aid in covert communication.
There are several methods of steganography, including using least significant bit (LSB) manipulation, where the hidden information is concealed within the least significant bits of the carrier data. Other techniques involve modifying the characteristics of the file, such as altering the color channels or the frequency spectrum, to embed the hidden message.
Steganography differs from cryptography in that it focuses on hiding the existence of the message, while cryptography focuses on scrambling the contents of the message itself. Both techniques are often used in combination to provide enhanced security.
With the increasing digitalization of communication and the ease of sharing information, steganography has become an important tool in ensuring the confidentiality and integrity of sensitive data. However, it can also be misused for illicit purposes, such as hiding malware or facilitating covert activities.
