Which term describes the unlawful practice of using someone else's personal information for fraudulent purposes?

The correct term that describes the unlawful practice of using someone else's personal information for fraudulent purposes is identity theft. This term specifically refers to the act of stealing someone’s personal data, such as Social Security numbers, credit card details, or banking information, and using it without their consent for financial gain or other fraudulent activities.

Identity theft can lead to severe consequences for the victim, including financial loss, damage to their credit score, and a lengthy process to restore their identity. This concept hinges on the unauthorized use of another individual’s sensitive information, making it distinct from other forms of fraud that may not involve personal data theft.

In contrast, credit fraud implies fraudulent activities specifically related to credit cards or credit accounts, but doesn't encompass the broader spectrum of personal information theft that identity theft does. Fraudulent conversion refers to the improper use of someone’s property, while embezzlement involves the misappropriation of funds or property entrusted to an individual, neither of which specifically denote the unauthorized use of personal information. Thus, identity theft is the most precise term for the scenario described.
