摘要
从发明人提供的背景信息中，新闻记者获得了以下引文：“作为确定是否向用户授予内容的一部分(例如，作为确定是否向呼叫者提供对提供银行信息的电话系统的访问的一部分)，可以向用户设备的用户提示一个或多个认证问题。这些问题例如涉及：用户的密码、用户的个人识别号码(PIN)等。这些问题可以基于用户的个人信息额外地和/或本机地生成。例如，当设置帐户时，用户可以对预先确定的问题(例如，“你父亲出生在哪里”、“你高中时最好的朋友是谁？”)提供各种答案，作为另一个例子，可以查询商业上可用的个人信息数据库以确定用户的个人信息(例如，他们的出生日期、出生地点等)，并且该信息可以用于生成认证问题(例如，“你出生在哪里，”“在哪一年？”）。这些类型的身份验证问题的潜在缺点是，对于掌握特定用户信息的人来说，正确答案可能是可以获得和/或猜测的。
Abstract
From the background information supplied by the inventors, news correspondents o btained the following quote: “Aspart of determining whether to grant a user acc ess to content (e.g., as part of determining whether to provide a caller access to a telephone system that provides banking information), a user of the user dev ice may be prompted with one or more authentication questions. Such questions ma y relate to, for example, a password of the user, a personal identification numb er (PIN) of the user, or the like. Those questions may additionally and/or alter natively be generated based on personal information of the user. For example, when setting up an account, a user may provide a variety of answers to predetermined questions (e.g., “Where was your father born?,” “Who was your best friend in high school?”), and those questions may be presented to the user as part of an a uthentication process. As another example, a commercially-available database of personal information may be queried to determine personal information for a user (e.g., their birthdate, birth location, etc.), and that information may be used to generate an authentication question (e.g., “Where were you born, and in what year?”). A potential downside of these types of authentication questions is that the correct answers may be obtainable and/or guessable for someone who has information about a particular user.
