Abstract: The invention relates to an NFC device configured for receiving a request to perform a transaction. In response to receiving the request, sensor data from one or more sensors of the NFC device is fed into a first classifier. The sensor data comprises environment parameters of the NFC device. The first classifier determines if sensor data provided as input to the first classifier were sensed in a transaction-typical environment or in a transaction-atypical environment. In case the first classifier determines that the sensor data is indicative of a transaction-atypical environment, the first classifier blocks the transaction or requests a user to confirm the transaction and blocks the transaction until the confirmation is received.

Abstract: A mechanism is provided for managing user accounts used on the data processing system. A first user account and second user account are initialized. Responsive to a user attempting to perform an activity from a user account in a set of user accounts under which the user is currently logged in, a determination is made as to whether an identifier associated with the activity is associated with a set of identifiers of the user account under which the user is currently logged in. Responsive to the identifier associated with the activity being associated with the set of identifiers of the user account under which the user is currently logged in, the user is allowed access to perform the activity. Responsive to the identifier associated with the activity being associated with a set of identifiers of another user account on the data processing system, the activity is denied.

Abstract: An ability to monitor the performance of a threaded application is provided. A thread that is executing is detected, wherein the thread is spawned by a threaded application. A thread class of the thread is determined. A performance metric of the thread is measured. A trend that describes a consumption of the performance metric as a function of percent execution time is interpolated. In response to determining that a threshold associated with the performance metric is exceeded based on a comparison of the trend to a trend template that is associated with the performance metric, an alert is issued. The alert identifies the thread as an abnormally executed thread in order to trigger a corrective action that improves a performance of a computing device that is configured to execute the threaded application.
