Smart number

Last updated

A smart number is any synthetic unique identifier that communicates additional information about the entity identified. The smart number is conceptually similar to a superkey as defined in the relational model of database organization, but, is intended to inform end users about status of accounts. The term has fallen out of common usage since using one number to carry so much information is considered bad practice.

Common examples of smart numbers in use today include:

The term smart number may also apply to non-geographic telephone numbers, such as Australia's 13, 1300 and 1800 vanity numbers and freephone numbers. See Intelligent Network.

<span class="mw-page-title-main">Identity theft</span> Deliberate use of someone elses identity, usually as a method to gain a financial advantage

Identity theft occurs when someone uses another person's personal 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 defined throughout both the U.K. and the U.S. as the theft of personally identifiable information. Identity theft deliberately uses someone else's identity as a method to gain financial advantages or obtain credit and other benefits, and perhaps to cause other person's disadvantages or loss. The person whose identity has been stolen may suffer adverse consequences, especially if they are falsely held responsible for the perpetrator's actions. Personally identifiable information generally includes a person's name, date of birth, social security number, driver's license number, bank account or credit card numbers, PINs, electronic signatures, fingerprints, passwords, or any other information that can be used to access a person's financial resources.

It was originally passed in 1970, and is enforced by the U.S. Federal Trade Commission, the Consumer Financial Protection Bureau, and private litigants.
