A system and method to authenticate users on a computing system using a free text behavioral biometric method by recording on the computer system a dataset for each user to be authenticated to create a user profile for each user to be authenticated, each data set comprising a plurality of free-text keystrokes entered by a respective user on a computer that is part of the computing system, and storing each user profile in the memory, subsequently collecting the keystrokes of a user to be authenticated as the user enters text on a keyboard connected to the computing system, creating a plurality of graphs based on the collection of keystrokes entered by the user and calculating n instance based tail area density (ITAD) metric, and then combining the ITAD metric for each graph duration into a single similarity score.

System and method to authenticate users on a computing system using a free text behavioral biometric method

A method for determining location of a target within an indoor environment, including the steps of: classifying a set of anchors having known locations within the indoor environment and a set of targets having unknown locations within the indoor environment, wherein each of the anchors and targets comprise hardware having sensors and wireless communication capabilities; creating a set of ordinal pair data sets comprising relative distances between each target and all anchors; ranking and aggregating the ordinal pair data sets to produce a set of dissimilarities that approximate distances; transforming the dissimilarities into estimated distances between each anchor and target using the known distances between the anchors as calibration; and inferring location of targets by formulating and solving a multidimensional unfolding optimization.

Determining localization from ordinal comparison data

A method for localization of a target device within an environment, the method comprising the steps of: (i) receiving, by a target device, a plurality of wireless signals transmitted from one or more anchor devices within the environment; (ii) determining, by a target device, a received signal strength indication for at least some of the received plurality of wireless signals; (iii) estimating, based on the determined received signal strength indications, a distance from the target device to each of the one or more anchor devices from which a wireless signal was received; and (iv) estimating, based on the estimated distances, a location of the target device within the environment.
