Problems solved by technology

The existing safe space is generally surrounded by a fence frame and two upper and lower PCB boards. The fence frame is generally formed by stacking and welding multiple PCB boards, and the fence frame is also welded with the upper and lower PCB boards. The structure is relatively complicated and production The process is complicated, the product defect rate is high, and the cost is expensive

Embodiment Construction

[0016] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail with reference to the accompanying drawings.

[0017] Such as Figure 1~2 As shown, a protection device for preventing data theft in an electronic circuit includes an upper PCB board 100 and a lower PCB board 500, and safety circuits are respectively made in the upper PCB board 100 and the lower PCB board 500, and the upper PCB board 100 Between the lower PCB board 500, there is a frame-shaped zebra bracket 300 that surrounds a safe space to place sensitive devices. The zebra bracket 300 is provided with several vertical slots 310. Inside the slots 310 Corresponding zebra strips 200 are respectively installed, and the outer peripheral surface of the zebra strip support 300 is covered with a layer of easily torn FPC board 400, and a safety grid line (ie, safe mesh wiring) is arranged inside the FPC board 400...

Abstract

The invention relates to a protection device and a protection method for preventing data interception in an electronic circuit. Firstly, a peripheral surface of a zebra strip support is covered with an FPC (Flexible Printed Circuit) through an adhesive layer, and subsequently, zebra strips are mounted in corresponding slotted holes formed in the zebra strip support, respectively, and each covering pin of the FPC is enabled to cover the surface of one end of the corresponding zebra strip; next, the zebra strip support is mounted between an upper PCB (Printed Circuit Board) and a lower PCB to define a safe space into which a sensitive device needing to be protected is put; a safety line of the upper PCB, a safety grid line of the FPC and a safety line of the lower PCB are electrically connected through the zebra strips into a safety circuit. When the FPC easy to tear is damaged and a safety attack is carried out through a removal action of the upper PCB or the lower PCB, a protection mechanism of the safety circuit is triggered to achieve a safety protection effect. The protection device has the advantages of novel design, simple structure, convenient production, relatively low cost, high safety and reliability, and the like.

Description

technical field [0001] The invention relates to a protection device and method for preventing data theft in an electronic circuit. Background technique [0002] Sensitive data and sensitive components of financial terminal equipment such as POS machines must be protected. When an external attack occurs, the device can alarm and lock the terminal equipment. In order to protect these sensitive data and sensitive devices, financial terminal devices generally design a safe space, and place those sensitive data and sensitive devices that need to be protected in the safe space. The existing safe space is generally surrounded by a fence frame and two upper and lower PCB boards. The fence frame is generally formed by stacking and welding multiple PCB boards, and the fence frame is also welded with the upper and lower PCB boards. The structure is relatively complicated and production The process is complicated, the product defect rate is high, and the cost is expensive. Contents o...
