What must be proven for a case of 'identity theft'?

To establish a case of identity theft, it is essential to demonstrate that the perpetrator has utilized someone else's stolen personal information for fraudulent purposes. This encompasses actions such as making unauthorized purchases, opening new accounts, or obtaining services in the name of the victim, all of which rely on the misuse of personal data like Social Security numbers, bank account details, or credit card information. This aspect of proving fraud highlights the intention behind identity theft and the impact it has on the victim's financial and personal security.

The other options do not meet the critical criteria for identity theft. Simply admitting to possessing personal identification does not encompass the fraudulent intent or resulting harm necessary to establish a case. Obtaining consent from the individual involved would mean that the act is legitimate and not theft. Lastly, a straightforward theft of physical documentation does not involve the fraud aspect that identity theft requires; it is more about the unauthorized use of the stolen information itself.
