Final answer:
Identity theft is the unauthorized use of someone's private information, a term also known as "True-name Fraud". It can result in significant financial damage and credit rating harm. Quick response and protective measures are critical for victims.
Step-by-step explanation:
The term used to describe the unauthorized use of someone's private information is identity theft, also known as "True-name Fraud". When someone wrongfully acquires and uses a consumer's personal identification, credit, or account information without their permission, it constitutes identity theft. This can lead to significant financial harm to the victim, as their information may be used to deplete savings accounts, incur considerable debts through credit card fraud, or make large-ticket purchases - which can harm their credit rating and financial stability.
Victims can take steps to protect their information, such as monitoring credit reports, using strong, unique passwords, and being cautious about sharing personal information online. If identity theft is suspected, it is essential to act quickly by notifying relevant financial institutions, filing a report with law enforcement, and possibly engaging credit monitoring or identity theft protection services.
