1. A method for securely authenticating an identity of an individual using a communications device based on a pattern that is traced by the individual, comprising: identifying a defined pattern by a user interface of the communications device to the individual for the individual to currently trace; receiving a currently traced pattern generated from continuously tracing the defined pattern by the individual from an initial point on the defined pattern to an end point on the defined pattern via the user interface of the communications device; capturing, from the currently traced pattern, current motion-based behavior data generated by the individual continuously tracing the defined pattern from the initial point to the end point, the current motion-based behavior data including a plurality of variables; accumulating previously captured motion-based behavior data captured from each of a plurality of previously traced patterns previously traced by the individual, the previously captured motion-based behavior data including the plurality of variables; determining, for each of the plurality of variables, a threshold that the variable is to be within using the previously captured motion-based behavior data; and comparing each variable of the current motion-based behavior data with a corresponding variable of the previously captured motion-based behavior data to determine whether each variable of the current motion-based behavior data is within the threshold of the corresponding variable of the previously captured motion-based behavior data.
