Problems solved by technology
At present, the protection of financial payment terminal equipment is limited to the anti-removal and anti-sabotage protection of its outer casing and input keyboard. Once the outer casing is successfully removed, the thief can pass through the MCU line pins located in the pin through holes. Attack the MCU, so as to easily obtain the user's financial password and other data information, so that the safe performance of the financial payment device cannot be well guaranteed, and the user's financial information has security risks

The invention discloses a safety protection device capable of preventing information stealing through MCU circuit pins. A plurality of pin through holes and a plurality of buried holes are arranged in a mainboard, the pin through holes penetrate from the front to the back and are used for arranging circuit pins of an MCU, the MCU with a detection circuit and a self-destruction circuit is fixedly arranged in front of the mainboard, the circuit pins behind the MCU are arranged in the pin through holes and the buried holes respectively, an MCU cover plate with a protection circuit is fixedly arranged behind the mainboard, and the MCU cover plate covers the pin through holes, so that the circuit pins of the MCU are enabled not to be exposed outside. The protection circuit in the MCU cover plate is connected with the detection circuit in the MCU. If the protection circuit in the MCU cover plate is broken or disconnected from the detection circuit, the MCU starts the self-destruction circuit so as to eliminate data stored in the MCU. The safety protection device disclosed by the invention greatly increases the difficult in stealing the data stored in the MCU through the MCU circuit pins, and increases the safe application performance of financial payment terminal equipment.
Description
technical field [0001] The invention relates to the field of anti-theft technology protection on financial transaction terminal equipment, in particular to a safety protection device for preventing theft through MCU line pins. Background technique [0002] With the development and application of information technology, financial payment has been widely used in people's daily life. Most formal business places such as supermarkets and specialty stores are equipped with financial payment terminal equipment, such as POS machines. People can conveniently make financial payment through financial payment terminal equipment during the shopping process. Financial payment involves users' financial information and other data. Once it is stolen, the consequences will be very serious. Therefore, the security performance of financial payment terminal equipment is also receiving more and more attention. . The MCU installed on the main board in the financial payment terminal equipment, ref...
