Hiding Secrets: Steganography in Digital Arts and NFTs

Image steganography is a technique for hiding files inside other files, being an image, a text, a video, or anything else. Images are just streams of bytes like any other file, making them a particularly effective medium for concealing secret text and other data. The same idea can be used to attach a complete file to an image using the RAR archive format. An image viewer only reads the code related to displaying the image and ignores any other files contained within the archive. A malicious actor or program can easily extract the appended file.
