An apparatus, method and package for electronic tamper detection. In one example, an apparatus, device or package for electronic tamper detection includes: a first inductor positioned at a first distance from a first conductive surface; a first oscillator generating a first frequency in dependence upon the first inductor; and a comparator setting a tamper detected status if the generated first frequency is not within an error tolerance to a pre-stored first frequency. One example of a method for fabricating an electronic tamper detection apparatus, device, or package is also provided.
