Patent ID: 8260740

Claim:
A computerized method for associating a prescribed user of an electronic system with a demographic group by measuring behavioral dynamics in operating at least one input device, the method comprising: capturing input behavioral data for a plurality of users to include the prescribed user, the input behavioral data related to measured interactions with the at least one input device, in which the measured interactions include a first interaction and a second interaction distinct from the first interaction; maintaining a plurality of wide-population probability distribution representations for a wide population of users, in which each of the plurality of wide-population probability distribution representations for a wide population is associated to an interaction with an input device; maintaining a plurality of demographic probability distribution representations for a plurality of demographic groups, in which each of the plurality of demographic probability distribution representations is associated to the interaction with the input device; comparing (a) input behavioral data associated with the prescribed user performing the first interaction, (b) the probability distribution representation for the first demographic group performing the first interaction, and (c) the probability distribution representation for the wide population performing the first interaction; comparing (a) input behavioral data associated with the prescribed user performing the second interaction, (b) the probability distribution representation for the first demographic group performing the second interaction, and (c) the probability distribution representation for the wide population performing the second interaction; determining a total probability based on the comparing steps; and associating the prescribed user with the first demographic group based when the total probability is above a prescribed threshold.
