Abstract
A method and device for data security including a printed circuit board and an integrated circuit each having a conductive trace layer shielded by a electrical shield layer. Tampering with either side of the device causes disturbance of a current flowing through a conductive trace layer used as an electrical shield. This triggers a security circuit to erase the data stored in the integrated circuit and stop data flow between the printed circuit board and the integrated circuit.
