Description
Technical field
The utility model relates to information security field, particularly a kind of storing card data erasing apparatus.
Background technology
Along with the development of infotech, the application in social life of various storage cards more and more widely, the important information that relates in the storage card is also more and more, this just need carry out wiping of necessity, avoids leakage of information.Though some common storage cards can be connected to computing machine and format through the mode of card reader; But just to common storage card; Some professional more intense storage cards are just inconvenient, and can only format usually, can not thoroughly remove internal data.
The utility model content
The utility model provides a kind of storing card data erasing apparatus, compatible all kinds storage card, and conveniently using, do not rely on computer, just can to wipe the equipment of storage card information extremely important.This device comprises:
Power module links to each other with central processing module, and the equipment of being used to provides power supply.
Key-press module links to each other with central processing module, is used to the user operation push-button is provided, and converts user's operation to instruction that central processing module can be discerned.
Display module links to each other with central processing module, is used to provide actions menu and data display window, selective equipment work pattern.Display module can adopt the low LCD of power consumption.
Storage card/USB/SATA identification module can be looked into various storage cards, and compatible various storage cards like SM/xD, SD/MS, CF, USB flash disk, SATA interface storage medium etc., link to each other with the data layout module, and identification memory card type and capacity also convert unified format into.
Usb interface module is used to connect computer, can upgrade or initialization operation to device;
Communication module; Link to each other with storage card/USB/SATA identification module, usb interface module, data layout module, central processing module, usb interface module; Be used for card type memory according to storage card/USB/SATA identification module identification; Obtain the data capacity information of storage card, also be used for the mode of operation of selecting according to the user is carried out erase operation to the corresponding sector position of storage card.
The data layout module; Be connected with central processing module, communication module, display module; But the instruction transformation that is used for that central processing module is sent becomes the recognition data form to be shown to the user checks and sends to communication module, and accepts the information of communication module feedback.
This programme has solved the problem of storage card efficient information, secure erase.
