Abstract
An authentication system is provided. The authentication system comprises a first component configured to obtain information specific to an individual, a second component configured to dynamically formulate at least one challenge question based on the information, a third component configured to cause the at least one challenge question to be presented on a device when the device is used to perform an act that involves authentication, and a fourth component configured to judge authenticity based on an answer to the at least one challenge question.
Claims23
A method for authentication, comprising:
- an authenticating entity obtaining information specific to an individual;
- the authenticating entity dynamically formulating at least one challenge question based on the information;
- the authenticating entity causing the at least one challenge question to be presented on a device when the device is used to perform an act that involves authentication by the authenticating entity;
- and
- the authenticating entity basing a determination of authenticity on a response to the at least one challenge question.
An authentication system, comprising:
- a first component configured to obtain information specific to an individual;
- a second component configured to dynamically formulate at least one challenge question based on the information;
- a third component configured to cause the at least one challenge question to be presented on a device when the device is used to perform an act that involves authentication;
- and
- a fourth component configured to judge authenticity based on an answer to the at least one challenge question.
A device, comprising:
- a processor configured such that the device transmits information related to an action that occurs on the device, and further configured such that, when a user of the device performs an act that involves authentication, the device presents at least one challenge question dynamically formulated based on the information.
