Abstract
An embodiment of an apparatus has a closed housing accommodating an element to be protected, and a pressure sensor coupled to a control unit configured to detect pressure variations within the housing upon opening the housing. The control unit is configured to activate countermeasures upon detecting opening of the housing. For example, the apparatus may be a set-top box, a cell phone, a television set, a printer ink cartridge of toner cartridge, or a meter, wherein the element to be protected is a semiconductor chip and relevant couplings, storing an enabling code or key.
