What does identity theft involve?

Identity theft specifically refers to the unauthorized use of someone else's personal information, such as their name, Social Security number, or financial account details, for fraudulent purposes. This typically involves obtaining financial benefits or services without the consent of the individual whose identity is being used.

In the context of the choices provided, this definition aligns perfectly with the selected answer, which highlights the act of using another person’s identity for personal gain without their permission. This encompasses various fraudulent activities that can lead to significant financial loss and distress for the victim, making it a serious crime.

The other options describe different forms of theft or unauthorized actions, but they do not specifically capture the essence of identity theft. For example, taking legal property or stealing physical items focuses on the physical act of theft rather than the fraudulent use of personal identity. Similarly, buying items on behalf of someone else implies consent and does not involve deception or unauthorized gain. Therefore, the emphasis on the unauthorized use of identity for illicit gain distinctly defines identity theft.
