1. A system, comprising:

  • at least one sensor configured to determine at least one of a position or movement of the system; and

    circuitry in communication with the at least one sensor, the circuitry being configured to;

    identify, using the at least one sensor, at least one behavior associated with use of the system over a first period of time;

    generate at least one timestamp associated with the at least one behavior and the first period of time;

    generate a user signature corresponding to the use of the system over the first period of time based at least in part upon the at least one behavior and the at least one timestamp,obtain a request to authenticate a user of the system from a system requesting authentication, wherein the request to authenticate the user indicates one of a higher level of authentication or a lower level of authentication,in response to the request, determine whether use of the system over a second period of time other than the first period of time corresponds to the user signature and identify a deviation between the use of the computing device over the second period of time and the use of the computing device over the first period of time;

    when the request to authenticate the user indicates the higher level of authentication, comparing the deviation against a lower level of deviation permitted for authentication of the user;

    and when the request to authenticate the user indicates the lower level of authentication, comparing the deviation against a higher level of deviation permitted for authentication of the user; and

    authenticating the user when the use of the computing device over the second period of time corresponds to the use of the computing device over the first period of time in accordance with the user signature.
