What is a reason to use steganography?

Comprehensive and Detailed Explanation From Exact Extract:

Steganography is used to save or embed secret data within another file or medium, allowing covert communication without alerting observers to the presence of the data.

The goal is to conceal, not highlight or delete data.

It does not erase or delete secret data; instead, it hides it.

This aligns with standard definitions in cybersecurity and forensic literature including NIST's cybersecurity frameworks.
