Data protection device of terminal equipment

Abstract

The invention discloses a data protection device of terminal equipment. The data protection device of terminal equipment comprises a self-reset switch, a reflective photoelectric switch and a single-chip microcomputer. The self-reset switch is abutted against a shell of the terminal equipment to be kept in a triggered state under abutting pressure of the shell and outputs an electric signal. The reflective photoelectric switch is arranged in the shell of the terminal equipment, a light ray signal sent by a transmitter of the reflective photoelectric switch is reflected by the shell and the received by a receiver, and the reflective photoelectric switch is kept in a triggered state and outputs an electric signal. The single-chip microcomputer is respectively connected with the self-reset switch and the reflective photoelectric switch to detect the electric signals outputted by the self-reset switch and the reflective photoelectric switch and clear application data when one of the two electric signals leaps, and accordingly dual protection of data in the terminal equipment is realized, data theft is effectively avoided on the basis that a shell material is unchanged, and increasing of production cost and processing cost is avoided.

Description

technical field [0001] The present invention relates to terminal equipment, in particular to a terminal equipment data protection device. Background technique [0002] With the rapid development of information technology, personal payment terminals and financial consumer POS machines are more and more widely used. Under this premise, the data security of terminal equipment is very important. This requires better security on the hardware of the terminal equipment to prevent the equipment from being forcibly disassembled. In the existing terminal equipment, the circuit board with data processing and data storage functions is fixed in the casing. When stealing data Or when dismantling the entire shell or opening the shell by cutting, etc., the external device can be connected to the circuit board, thereby stealing the data in the terminal device, which poses a threat to data security. Therefore, this terminal device Data protection performance is poor. Most of the existing t...

This requires better security on the hardware of the terminal equipment to prevent the equipment from being forcibly disassembled. In the existing terminal equipment, the circuit board with data processing and data storage functions is fixed in the casing. When stealing data Or when dismantling the entire shell or opening the shell by cutting, etc., the external device can be connected to the circuit board, thereby stealing the data in the terminal device, which poses a threat to data security. Therefore, this terminal device Data protection performance is poor

Most of the existing terminal devices are made of plastic shells. If the shells are replaced with special materials to prevent forced disassembly, it will bring many problems such as high cost and difficult processing.
