Abstract
A system and method for detecting an unauthorized attempt to access components in a housing of a portable electronic device. The housing is secured in a closed state by a mechanical fastener that couples a first portion of the housing to a second portion of the housing. The mechanical fastener has a top end disposed within a recess in the housing. A ball bearing is first disposed within the recess above the top end of the fastener, after which at least a portion of the recess is filled with a curable resin. Later, a portion of the housing proximate the recess is visually inspected. In response to the visual inspection, a determination is made as to whether there has been an unauthorized attempt to access components in the housing.
