Out of Wallet refers to private data used for authentication in activities such as telephone banking or internet banking in order to prevent identity theft. This practice can be a component in a knowledge-based authentication process. This data is taken to be data that is not available easily to persons apart from the user who would know this information but not likely to carry such information in his or her wallet. This data is now being generated automatically through convergence of databases. Typical ''out of wallet'' questions a person may be asked include; #What was the color of your first car? #What is the name of the first school you attended? #What is the name of the hospital you were born in? Such information is available to a database compiler but not readily available to criminals who may be attempting identity theft.〔 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Out of wallet」の詳細全文を読む スポンサード リンク
