Abstract
Embodiments may provide Digital Rights Management techniques, not to make the reverse engineering process harder, but rather to provide detection of reverse engineering of PCBs, such as by copying of layers of trace layout, so as to enable pursuing legal remedies against the violators. For example, in an embodiment, a method of information encoding may be implemented in a computer comprising a processor, memory accessible by the processor, and computer program instructions stored in the memory and executable by the processor, the method may comprise receiving, at the computer system, information to be encoded in a printed circuit board wiring trace layout and laying out, at the computer system, a plurality of printed circuit board wiring traces so as to encode the received information.
