Abstract
Disclosed is a printer capable of self-destruct protection. Provided is a printer capable of self-destruct protection and of compact structure, easy usage and high safety factor. The printer includes a power source, a PC interface and a print module. The print module is connected with a PC via the PC interface. The printer also includes a safety CPU, an anti-detection metal mesh and a backup battery; the safety CPU is connected in series between the print module and the PC interface, and is connected respectively to the anti-detection metal mesh and the backup battery; and the safety CPU is equipped inside with a self-destruct module connected to the anti-detection metal mesh. When the printer capable of self-destruct protection is in use, the anti-detection metal mesh is monitored in real time via the safety CPU; and once destruction of the anti-detection metal mesh is detected and an open circuit is formed, the self-destruct module is immediately started to erase data temporarily stored in the safety CPU.
Description
Technical field
The utility model relates to printer applications field, relate in particular to can self-destruction the improvement of printer of protection.
Background technology
At present, most domestic printer all adopts general-purpose type structure, receives after the data of computer (PC) transmission, and printer starts working, and meanwhile, these data is carried out to the storage of short-term.Like this, at some Sensitive Domains, during as the printing of design sample carrying out the information such as invoice, lottery ticket, reward voucher, false proof authentication code or some products, the data of above-mentioned of short duration storage will be brought and lose or stolen risk.Specifically: once printer is under powering-off state, can directly to it, disassemble, thereby take out the chip for short-term storage data.Like this.Significantly reduced in use safety coefficient when printer uses.
Utility model content
The utility model is for above problem, a kind of delicate structure is provided, easy to use and safety coefficient is high can self-destruction protection printer.
The technical solution of the utility model is: comprise power supply, PC interface and print module, described print module is connected with PC by PC interface;
Described printer also comprises safe CPU, anti-detection wire netting and backup battery, described safe CPU is serially connected between print module and PC interface and safe CPU connects respectively described anti-detection wire netting and backup battery, is provided with the self-destruction module being connected with described anti-detection wire netting in described safe CPU.
Described anti-detection wire netting comprises some pins and is connected to the conductive mesh between some described pins.
Described printer also comprises the identification module being connected with described safe CPU, and described identification module comprises smart card read-write chip and smart card draw-in groove, and described smart card draw-in groove connects described safe CPU by described smart card read-write chip.
When the utility model is used, can to anti-detection wire netting, monitor in real time by safe CPU, once anti-detection wire netting be detected, suffer to destroy to form and open circuit, start immediately self-destruction module, data temporary in safe CPU are wiped.Like this, by the cooperation of self-destruction module and anti-detection wire netting, when printer is disassembled by external force, can wipe printer in advance in temporary sensitive information, thereby avoid occurring stolen, clone, the phenomenon of plagiarizing, effectively protected the safety of printing environment.Meanwhile, in this case, also set up backup battery, made when power supply no-voltage, can support by backup battery the operation of safe CPU and anti-detection wire netting.
Accompanying drawing explanation
Fig. 1 is functional block diagram of the present utility model.
The specific embodiment
The utility model as shown in Figure 1, comprises power supply, PC interface and print module, and described print module is connected with PC by PC interface;
Described printer also comprises safe CPU, anti-detection wire netting and backup battery, described safe CPU is serially connected between print module and PC interface and safe CPU connects respectively described anti-detection wire netting and backup battery, is provided with the self-destruction module being connected with described anti-detection wire netting in described safe CPU.During use, can to anti-detection wire netting, monitor in real time by safe CPU, once anti-detection wire netting be detected, suffer destroy to form and open circuit, start immediately self-destruction module, data temporary in safe CPU are wiped.Like this, by the cooperation of self-destruction module and anti-detection wire netting, when printer is disassembled by external force, can wipe printer in advance in temporary sensitive information, thereby avoid occurring stolen, clone, the phenomenon of plagiarizing, effectively protected the safety of printing environment.Meanwhile, in this case, also set up backup battery, made when power supply no-voltage, can support by backup battery the operation of safe CPU and anti-detection wire netting.
Described anti-detection wire netting comprises some pins and is connected to the conductive mesh between some described pins.
Described printer also comprises the identification module being connected with described safe CPU, and described identification module comprises smart card read-write chip and smart card draw-in groove, and described smart card draw-in groove connects described safe CPU by described smart card read-write chip.Identification module has also been set up in this case, and printer only can could worked after authentication (i.e. " mandate ").Meanwhile, if authentication failure starts self-destruction module and carries out data erase.Thereby further promoted security when printer uses.
