5 of the Best Steganography Tools in Linux: Hiding information inside other innocent files

Steganography is the art and process of putting one type of information inside another in an attempt to hide it. This is often done in situations where an individual wants to preserve secret information inside normal objects.

Steganography is not a new innovation. Since the time of ancient Greeks, historians have written about how cultures used steganography to hide information in plain sight. To that end, one famous account was Herodotus’s story of Histiaeus, where he tattooed a short message on a servant’s bare scalp. It is now possible to insert an entire book inside a simple JPEG photograph.

This guide shows five of the best steganography tools currently available in Linux: Steghide, Stegoshare, Wavsteg, Snow, and Steganoroute. It also shows you how you can hide your first message using these utilities.

Information can be concealed inside image, audio, text, and even TCP ICMP packets. And the image, audio and text files would still open and be processed like their original file types.

"Shufflecake is a tool for Linux that allows creation of multiple hidden volumes on a storage device in such a way that it is very difficult, even under forensic inspection, to prove the existence of such volumes. Each volume is encrypted with a different secret key, scrambled across the empty space of an underlying existing storage medium, and indistinguishable from random noise when not decrypted. Even if the presence of the Shufflecake software itself cannot be hidden -- and hence the presence of secret volumes is suspected -- the number of volumes is also hidden. This allows a user to create a hierarchy of plausible deniability, where 'most hidden' secret volumes are buried under 'less hidden' decoy volumes, whose passwords can be surrendered under pressure. In other words, a user can plausibly 'lie' to a coercive adversary about the existence of hidden data, by providing a password that unlocks 'decoy' data. Every volume can be managed independently as a virtual block device, i.e. partitioned, formatted with any filesystem of choice, and mounted and dismounted like a normal disc. The whole system is very fast, with only a minor slowdown in I/O throughput compared to a bare LUKS-encrypted disk, and with negligible waste of memory and disc space."

"You can consider Shufflecake a 'spiritual successor' of tools such as Truecrypt and Veracrypt, but vastly improved. First of all, it works natively on Linux, it supports any filesystem of choice, and can manage up to 15 nested volumes per device, so to make deniability of the existence of these partitions really plausible."

Hiding Secrets: Steganography in Digital Arts and NFTs

“If you want to keep a secret, you must also hide it from yourself.”
― George Orwell, 1984

The world of art has always been full of secrets; trying to achieve powerful meanings or sometimes by hiding real-life secrets, messages, treasures, tributes, or techniques... Artists love to put their marks into their art to make them memorable. For example, take software cracking teams - they make NFO ASCII art files for increasing respect in the scene.

But what happens when the whole world, including the art world, enters into the technological revolution?

Blockchain, mixed reality, quantum computing, NFTs, and AI construct a whole new generation where the meaning of art itself has changed. Modern technologies have merged virtual reality with actual reality.

If the world changes, we must find (cool) ways to adapt to it. Definitely, the world of Non Fungible Tokens took over the scene by converting digital formats like JPG, PNG, GIF, GLB, GLTF, MP3, MP4 into something uncopiable, unique.
