A keyboard safety protection device for protecting a point of sale (POS) device keyboard area from being attacked includes: a protection layer, a metal dome, and a keyboard printed circuit board, wherein a key gold finger and a safety processor are arranged on the keyboard PCB, the protection layer is composed of a layer of PVDF film and a first and second silver slurries, the first and the second silver slurries are coated on the surface of the PVDF film, the surfaces of the first and second silver slurries are provided with a first and second thin film layers respectively, the first and second silver slurries are electrically connected with the key gold finger, and the first and second silver slurries are electrically connected with the safety processor to form a safety detection circuit through the keyboard printed circuit board and the safety processor.

Keyboard safety protection device

A security protection device includes a cover circuit board comprising at least one inner wiring layer and a base circuit board comprising at least one inner wiring layer. The device further includes a security frame between the base circuit board and the cover circuit board, at least one electrically conductive wire being wound and included within the security frame to form at least one winding protection layer around sides of the security frame. The cover circuit board, the security frame, and the base circuit board form an enclosure enclosing a security zone, and the at least one inner wiring layer within the cover circuit board, the at least one inner wiring layer within the base circuit board, and the at least one electrically conductive wire within the security frame are connectable to a security mechanism configured to detect an intrusion into the security zone.

Security protection device and method

A security protection device includes a cover circuit board, at least one inner wiring layer being included within the cover circuit board. The device also includes a base circuit board, at least one inner wiring layer being included within the base circuit board. The device further includes a security frame between the base circuit board and the cover circuit board, at least one electrically conductive wire being wound and included within the security frame to form at least one winding protection layer around sides of the security frame. The cover circuit board, the security frame, and the base circuit board form an enclosure enclosing a security zone, and the at least one inner wiring layer within the cover circuit board, the at least one inner wiring layer within the base circuit board, and the at least one electrically conductive wire within the security frame are connectable to a security mechanism configured to detect an intrusion into the security zone.

The present invention is adapted for field of electronic circuit protection and provides a security protection box, for enclosing the protected region of a protected circuit board in order to protect the elements in the protected region. The security protection box comprises a circuit board. The circuit board with thin center and thick periphery forms a box shape, and has the circuit routing layers. The circuit routing layers trigger the associated circuit to erase or destroy the information in the elements in the protected region when the circuit routing layers are physically attacked. The present invention protects the elements in the protected region through covering the protected region on the protected circuit board with a circuit board having thin center and thick periphery.
