What is meant by cover up attack on an image?

A cover-up attack on an image refers to a form of manipulation where an adversary alters or obscures certain parts of an image to conceal information or mislead viewers. This can involve techniques like adding noise, blurring, or superimposing images to hide details or change the context. Such attacks can be particularly concerning in areas like security, forensics, and media, where the authenticity of visual content is critical. The goal is often to create doubt about the image's integrity or to hide malicious activity.
