<P> Identity theft is the deliberate use of someone else's identity, usually as a method to gain a financial advantage or obtain credit and other benefits in the other person's name, and perhaps to the other person's disadvantage or loss . The person whose identity has been assumed may suffer adverse consequences, especially if they are held responsible for the perpetrator's actions . Identity theft occurs when someone uses another's personally identifying information, like their name, identifying number, or credit card number, without their permission, to commit fraud or other crimes . The term identity theft was coined in 1964 . Since that time, the definition of identity theft has been statutorily prescribed throughout both the U.K. and the United States as the theft of personally identifying information, generally including a person's name, date of birth, social security number, driver's license number, bank account or credit card numbers, PIN numbers, electronic signatures, fingerprints, passwords, or any other information that can be used to access a person's financial resources . </P> <P> Determining the link between data breaches and identity theft is challenging, primarily because identity theft victims often do not know how their personal information was obtained, and identity theft is not always detectable by the individual victims, according to a report done for the FTC . Identity fraud is often but not necessarily the consequence of identity theft . Someone can steal or misappropriate personal information without then committing identity theft using the information about every person, such as when a major data breach occurs . A US Government Accountability Office study determined that "most breaches have not resulted in detected incidents of identity theft". The report also warned that "the full extent is unknown". A later unpublished study by Carnegie Mellon University noted that "Most often, the causes of identity theft is not known", but reported that someone else concluded that "the probability of becoming a victim to identity theft as a result of a data breach is...around only 2%". More recently, an association of consumer data companies noted that one of the largest data breaches ever, accounting for over four million records, resulted in only about 1,800 instances of identity theft, according to the company whose systems were breached . </P>
