Steganography represents the subtle art of concealing information in a variety of digital media.
This name comes from the combination of the Greek words “steganos” (which means hidden) and “graphein” (which means writing).
Unlike cryptography, which visibly encodes messages, this technique masks their very existence, making them invisible to unauthorized observers.
This technology operates primarily by exploiting the less significant parts of digital files: reverse image search can be used to detect steganographic images by identifying other versions of an image and verifying their origin.
The applications of this technique range from intellectual property protection to secure communication, while raising important questions in cybersecurity subject. Its ability to hide sensitive data can in fact be used for malicious intentions, in particular for the distribution of malicious software.
Modern steganography is based on a sophisticated process of concealing information in various types of digital media. Its effectiveness depends on its ability to exploit redundant areas of data without altering the perceptible quality of the support.
