11. A method of securing data stored on a first electronic device, the electronic device adapted to communicate with a second electronic device, the first electronic device including an application containing at least one preprogrammed security feature and having set therein an activation interval and a grace period, wherein the activation interval is a non-zero period and the grace period is a non-zero period, the method comprising the steps of:

  • automatically setting, upon communication between the first electronic device and the second electronic device, an activation timer within the first electronic device;

    at a point in time subsequent to the automatically setting, determining that the activation interval has elapsed based upon the activation timer;

    subsequent to the elapsing of the activation interval, automatically setting a grace timer within the first electronic device;

    if, prior to the grace period elapsing, communication is established between the first electronic device and the second electronic device, re-setting the activation timer within the first electronic device based upon a signal from the second electronic device; and

    if communication is not established between the first electronic device and the second electronic device prior to the grace period elapsing;

    determining that the grace period has elapsed based upon the grace timer;

    determining a size of selected electronic data on the first electronic device;

    creating a set of random data, wherein the size of the set of random data is equal to the size of the selected electronic data; and

    overwriting the selected electronic data with the set of random data.
