Abstract

The invention relates to a penetration attack preventing liquid crystal touch screen, comprising a liquid crystal touch screen. The penetration attack preventing liquid crystal touch screen is characterized in that N coil circuits are arranged on the liquid crystal touch screen; when the coil circuit is opened, the change of an electric signal of the coil circuit triggers an alarm mechanism; and N is a natural number. According to the invention, the penetration attack preventing liquid crystal touch screen has a protective device capable of preventing penetration attack; therefore, parts for preventing the penetration attack are reduced so that the cost is reduced; and system reliability is improved.

Description

technical field [0001] The invention relates to the technical field of financial terminal security, in particular to a liquid crystal touch screen that prevents penetration attacks. Background technique [0002] Existing financial terminals are equipped with touch controls for convenient operation. By destroying the touch screen, criminals can penetrate and attack the terminal system. Therefore, for security reasons, the terminal generally needs to design a machine anti-penetration attack mechanism. However, except for the protection structure designed on the terminal shell, the handheld terminal has no protection measures against the touch screen attack. It can be seen that there are security risks in the financial terminal. Contents of the invention [0003] In view of this, the object of the present invention is to provide a liquid crystal touch screen that prevents penetration attacks. [0004] The present invention is realized by the following scheme: a liquid cryst...
