Problems solved by technology
However, due to the different structures of the card readers, the small size and the narrow installation space inside the housing, this protection method is difficult to implement in practice, does not have universal applicability, and cannot monitor the disassembly and assembly status of the card reader in real time. As a result, it is impossible to detect abnormal shell disassembly and assembly behaviors on electronic equipment in time

The invention discloses an anti-sniffing refitting structure of electronic equipment. The structure comprises a first shell and a second shell which are installed in a mutually clamped mode, a detection circuit which is laid in the first shell and is in signal connection with an MCU, electrode pairs which are connected in series in the detection circuit and are arranged at intervals, and a conductor connecting piece which is arranged in the second shell and used for making contact with the electrode pairs so that the detection circuit can be connected, and the MCU triggers an abnormal refitting alarm when the detection circuit is disconnected. Therefore, when the electronic equipment is disassembled, the first shell and the second shell are separated from each other, and the conductor connecting piece is also separated from the electrode pairs along with the separation movement of the second shell, so that the detection circuit is interrupted, a detection port of the MCU receives an abnormal signal, and the abnormal refitting alarm is triggered immediately; and the shell disassembly and assembly state of the electronic equipment can be monitored in real time, and abnormal shell disassembly and assembly behaviors can be found in time. The invention further discloses an on-line anti-sniffing refitting monitoring system, which has the above beneficial effects.
Description
technical field [0001] The invention relates to the technical field of information security, in particular to an electronic device anti-sniffing modification structure. The invention also relates to an on-line anti-sniffer modification monitoring system. Background technique [0002] With the development of information technology, more and more electronic information interactive devices have been widely used. [0003] Taking the card reader as an example, the card reader is a device that reads card data and can also support data writing. Memory cards are widely used in smart phones, cameras and other electronic devices, so smart phones and cameras also function as card readers. According to different types of cards, card readers can be divided into IC card readers and long-distance card readers ( RFID electronic tag reader), etc. [0004] At present, password sniffing and RFID sniffing modification methods for card readers emerge in endlessly, and the technology is diffic...
