Hardware on a device, including sensors that may be embedded in or accessible to the device, extend the validity session of an authentication event by identifying behavior of the user periodically during the session. By detecting behavior that may be directly or indirectly unrelated to the application—but is necessarily present if the user remains the same—the session is extended for as long as that behavior is within some defined parameters. This process may be accomplished either by using an expert system or through the application of machine learning. Such a system may take input from sensors and detects a pattern in those inputs that coincide with the presence of that ephemeral personal or behavioral patterns that it is desired to detect. Using that detected behavior, the validity of a session can be extended using statements about the variance or invariance of the detected ephemeral personal or behavioral states.
