Claim:
1. A method for determining if data is being intercepted from a protected integrated circuit package, said method comprising: providing at least one integrated circuit in an encapsulant, wherein the at least one integrated circuit is a touch controller, wherein a first sensor layer comprised of X and Y co-planar electrodes is disposed within the encapsulant on a non-connecting side of a protected integrated circuit package wherein a second sensor layer comprised of X and Y co-planar electrodes is disposed within the encapsulant on a connecting side of the protected integrated circuit package, wherein the X and Y electrodes of the first and second sensor layers are coupled to the touch controller to thereby provide signals to the touch controller regarding an environment around the protected integrated circuit package; making a baseline measurement of an environment around the protected integrated circuit package using the sensor layer and the touch controller within the encapsulant of the protected integrated circuit package; recording the baseline measurement; making subsequent periodic measurements; comparing the baseline measurement and the subsequent periodic measurements to determine if there are changes in capacitance around the protected integrated circuit package; and performing an action if there are changes in capacitance that indicate that data is being intercepted from the protected integrated circuit package.
