The most common way steganography is accomplished is via ________.

• A. LSB
• B. Encryption
• C. Metadata
• D. Compression

Answer: (A)

Hiding data in the least significant bits of the cover file is the most common steganography approach. The least significant bit is the smallest part of a byte, so changing it typically alters the data by only 1 unit. In images, flipping the LSB of color channels changes the pixel value by a barely noticeable amount, and in audio, tweaking the LSB of samples usually stays within the range of inaudible variation. This makes the hidden payload blend into the cover medium with minimal perceptual impact while keeping the method simple and widely compatible with standard file formats. Encryption, metadata, and compression serve other purposes. Encryption hides the meaning of the data but not its existence, so it doesn’t conceal that something is embedded. Metadata can carry hidden data, but it’s metadata itself and more prone to discovery or alteration. Compression changes the data representation and size but isn’t a technique for hiding information within the content itself.
