Abstract
An electronic device for distorting sensitive information in one or more electromagnetic emanations from the electronic device is disclosed. The device has one or more active layers having one or more electronic components that emit the electromagnetic emanations and one or more conductive substrate layers planarity adjacent to one or more of the active layers that distort the electromagnetic emanations. In alternative embodiments of the inventions, shielding is added with frequency selective openings. In other alternative embodiments, a signal source is added to distort sensitive information.
