Which infringement of privacy involves using someone's name or likeness without permission?

The infringement of privacy that involves using someone's name or likeness without permission is referred to as appropriation. This legal concept centers on the idea that individuals have the right to control the commercial use of their identity and personal attributes. When someone uses another person’s name, image, or likeness—especially for commercial gain—without obtaining consent, it violates the individual’s rights under appropriation laws.

This area of privacy law is particularly relevant in contexts such as advertising and social media, where individuals may unintentionally find their identities misused. The principle is grounded in the notion that individuals deserve respect and autonomy over their persona, which commercial interests should not exploit without permission. Understanding appropriation is essential for public relations professionals who must navigate the ethics and legalities of utilizing individuals' identities in their campaigns.
