Steganography, the method of hiding data, has been encompassing for centuries. And in parallel to technological advances, steganography has also evolved and changed with the advent of computers and the internet.
Digital steganography usually involves hiding data inside innocuous files such as images, videos, and audio.
Today, digital steganography is one of the major elements in the toolboxes of observers and wicked attackers, as well as human rights activists and political protesters.
How does it work?
Attackers are frequently practicing. This method known as steganography, to trick internet users and hide malicious code past security scanners and firewalls. Unlike cryptography, which works to complex content so it can’t be explained. Steganography’s purpose is to hide the fact that content exists at all by installing it in something else. And since steganography is a concept, not a particular way of secret data delivery. It can be use in all sorts of ingenious (and distress) attacks.
More About Steganography
Steganography is an archaic method. When detectives in the Revolutionary War wrote in transparent ink or when Da Vinci installed hidden meaning in a sketch that was steganography. This works in the digital world, too, where a file like an image can be combined encoded with data. For example, pixel rates, brightness, and filter contexts for an image are usually change to modify the image’s appreciative look. But attackers can also handle them based on a hidden code with no concern for how the data make the picture look visually. This method can be use for ethical purposes, such as to avoid deletion or secure messages in Facebook photos. But this technique can also be use in the wrong way. For security guardians, the question is how to tell the difference among an image that’s been changed for lawful reasons and one that’s been developed to secretly include wicked information.
“Nothing is the alike twice, there is no design to look for, and the steg itself is fully undetectable,” says Simon Wiseman. He is the CTO of the British network defense firm Deep Secure, which is working on this platform. “With excellent statistics, if you’re fortunate, you might be able to get a sign that something’s odd. But that’s no choice as a defense because the false positive and false negative scale is however large. So disclosure does not work.”
