1. A method for determining if data is being intercepted or detection of an object near at least one protected component, said method comprising:

  • providing a substrate upon which are disposed at least one protected component having data, extending segments away from the surface of the substrate and over the at least one protected component to form a secure cage above a surface of the substratewherein the plurality of flying sense electrodes are not coplanar with the substrate, andproviding a capacitive touch controller that is coupled to each of the plurality of flying sense electrode segments and detects changes in capacitance on any of the plurality of flying sense electrode segments;

    making baseline measurements of the flying sense electrode segments to measure an environment when no object is present;

    recording the baseline measurements;

    making subsequent integrity measurements on the plurality of flying sense electrode segments;

    that indicate the presence of an object; and

    performing an action if there are changes in capacitance that indicate that data is being intercepted or an object is detected near the at least one protected component.
