Abstract: User activity on a mobile device is monitored and collected, and a resource usage model is constructed. The resource usage model describes a set of contexts in which the mobile device, and is the basis for determining a first exhaustion point for a resource. Based on the monitored activity, a prediction of a second exhaustion point for the resource time is made. If the second exhaustion point is prior to the first exhaustion point, usage of the resource is reduced.

Abstract: Embodiments are directed to a system and method for authenticating a user of a client computer making a request to a server computer providing access to a network resource through an authentication platform that issues a challenge in response to the request requiring authentication of the user identity through a reply from the client computer, determining one or more items of context information related to at least one of the user, the request, and the client computer, and determining a disposition of the request based on the reply and the one or more items of context information. The reply includes a user password and may be provided by an authorizing client device.

The reply includes a user password and may be provided by an authorizing client device coupled to the client computer over a wireless communications link.

Abstract: Security is enhanced for a user of a mobile device by monitoring and controlling resource usage. Usage information associated with a mobile device is collected. The collected information is used to build a usage model for a user of the mobile device that describes a set of contexts in which the mobile device is used. User activity on the device is monitored and the model is consulted to determine a first time after which it will be acceptable for a battery of the mobile device to fall below a threshold charge level. Based on the monitored activity, a prediction of a second time is made for when the battery will fall below the threshold charge level. If the second time is before or a predetermined amount of time before the first time, usage of the battery is reduced, else, usage of the battery is not reduced.
