What term describes the unauthorized use of another person's name or likeness for personal gain?

The term that accurately describes the unauthorized use of another person's name or likeness for personal gain is appropriation. This legal concept primarily falls within the realm of intellectual property and privacy rights. Appropriation occurs when someone uses another individual's identity, whether it be their name, likeness, or persona, without consent and typically for commercial purposes.

For example, if a company uses a celebrity's image in an advertisement without permission, it is committing appropriation. This violation can lead to legal implications as the individual whose likeness was used may seek damages, asserting that their identity has been exploited for profit without giving consent.

The other terms do not specifically address this scenario: wrongful interference pertains to illegal disruption of contractual relationships; conversion refers to the unauthorized taking or use of someone else's property; and sovereign immunity describes the legal doctrine that prevents the government or its agents from being sued without its consent. These terms focus on different aspects of legal rights and responsibilities and do not encompass the specific act of unauthorized likeness usage that appropriation does.
