REDUCING AUTHENTICATION CONFIDENCE OVER TIME BASED ON USER HISTORY

摘要

Technologies are provided in embodiments to manage an authentication confirmation score. Embodiments are configured to identify, in absolute session time, a beginning time and an ending time of an interval of an active user session on a client. Embodiments are also configured to determine a first value representing a first subset of a set of prior user sessions, where the prior user sessions of the first subset were active for at least as long as the beginning time. Embodiments can also determine a second value representing a second subset of the set of prior user sessions, where the prior user sessions of the second subset were active for at least as long as the ending time. Embodiments also determine, based on the first and second values, a decay rate for the authentication confidence score of the active user session. In some embodiments, the set is based on context attributes.

1. An apparatus to manage an authentication confidence score, the apparatus comprising:
at least one processor; at least one memory element; at least one module adapted, when executed by the processor, to:
identify, in absolute session time, in absolute session time, a beginning time and an ending time of an interval of an active user session on a client;determine a first value representing a first subset of a set of prior user sessions, wherein the prior user sessions of the first subset were active for at least as long as the beginning time;determine a second value representing a second subset of the set of prior user sessions, wherein the prior user sessions of the second subset were active for at least as long as the ending time; anddetermine, based on the first and second values, a decay rate for the authentication confidence score of the active user session.
