Abstract

A method and device for data security including a printed circuit board (30) and an integrated circuit (20) each having a conductive trace layer shielded by a electrical shield layer (12, 32) . Tampering with either side of the device causes disturbance of a current flowing through a conductive trace layer (13) used as an electrical shield. This triggers a security circuit to erase the data stored in the integrated circuit (20) and stop data flow between the printed circuit board (30) and the integrated circuit (20) .
