Abstract: A system and related method are provided for user authentication and dynamic usability of touch-screen devices. The system utilizes probability distribution representations including an authorized user probability distribution representation and a global or wide population probability distribution representation, to associate the purported authorized user to the authorized user. Touch dynamics or data, or other data from similar measurable characteristics, can be utilized to associate the purported authorized user and the authorized user and to determine optimal positions and sizes for user interface components.

Abstract: A system and a related method are disclosed for authenticating an electronic transaction. Input behavioral data is captured related to measured interactions with at least one input device. The input data is compared to probability distribution representations for a demographic group and for a wide population, performing the measured interaction(s). The system is configured to authenticate the electronic transaction based on the comparing.

Abstract: A system and a related method are disclosed for authenticating a user of an electronic system. The system, and related method access (a) data relating to a defined interaction with an input device for a purported authorized user, (b) a probability distribution representation for the defined interaction for an authorized user, and (c) a probability distribution representation for the defined interaction for a wide population, from which it can determine value indicative of whether the purported authorized user is the authorized user. The purported authorized user can be authenticated as the authorized user, if the value satisfies a prescribed threshold.

Abstract: This invention discloses a system for determining whether a purported or alleged authorized user is in fact the authorized user, by comparing new data on a real-time basis against probability distribution representations including an authorized user probability distribution representation and a global or wide population probability distribution representation, to provide a probability as to whether the purported authorized user is the authorized user. This invention may utilize keyboard dynamics, data, X-Y device data, or other data from similar measurable characteristics, to determine the probability that the new data from the purported authorized user indicates or identifies that user as the authorized user.
