One aspect of the invention includes one or more security devices embedded on one of the two surfaces, or between the two surfaces, of a compact disc or digital video disc to impede the counterfeiting of the disc. Real or illusionary text lines are identified in the captured documents. The support body is essentially plate-like and rectangular and forms part of the rear wall of the circuit breaker. Alternatively, if there is no watchpoint, normal paging operations can be resumed if necessary.
