Using glass weave marker structure to authenticate printed circuit boards

A method comprising:

• obtaining a representation of a marker structure defined within a printed circuit board (PCB);
• and
• comparing the representation of the marker structure with an authentication identifier (ID) to determine whether a match exists between the representation of the marker structure and the authentication ID.

An apparatus comprising:

• a printed circuit board (PCB) comprising a layer, wherein a marker structure comprising a combination of markers is defined within the layer, each marker is provided at a predetermined interval along the layer and has one or more unique properties, wherein the layer comprises a plurality of bundles of fibers combining to form the layer, and the marker structure comprises bundles of fibers provided at a location within the layer that differ in composition, size, and shape in relation to bundles of fibers provided within the layer outside the location;
• and
• a security chip coupled with the PCB and comprising memory that stores an authentication identifier (ID) of the PCB.
