Abstract
The safeguard mechanism for memory card includes dividing the memory card into several data storing blocks, using one of the data storing blocks in storing application program while setting an idle space in every block, connecting an electronic equipment to the memory card for reading out the application program, and storing one cipher in the idle space via the application program to encipher the data storing block. Thus, during reading out the data stored in the data storing area, cipher must be input correctly so that the application program decipher the data storing area before the data in the data storing area are accessed.
Description
Technical field
The present invention relates to the memory card of computing machine; especially a kind of safeguard mechanism for record card; (Memory Card) is divided into several data storage blocks with a memory card; and use one of them data storage block storage application program (AP); but make the application program (AP) in this data storage district of nationality; the data storage block is encrypted pinning, to reach the purpose of protection data.
Background technology
In recent years, because Portable IA system popular causes the generally use of memory card (Memory Card) indirectly, allow the user can be in memory card with the data storage among the Portable IA, perhaps, use Portable IA to read data stored in the memory card.And the main frame of Portable IA system all has the function of the pinning of encrypting at present; use and then protect can prevent to meet with other people to steal that its data is unlikely to leak, only, general commercially available memory card; all do not have to be provided with and encrypt the function of pinning, so that the anxiety that still has data to leak.
Summary of the invention
In view of this, for improving the shortcoming that above-mentioned known memory card has data to leak, special development and Design goes out a kind of simple and effective safeguard mechanism for record card, with the disappearance of the known memory card of forgoing.
A purpose of the present invention; provide a kind of safeguard mechanism for record card; (Memory Card) is divided into several data storage blocks with a memory card; and use one of them data storage block storage application program (AP); and be provided with an idle space in each data storage block; make and in this idle space, to store a password; make memory card and an electronic installation (as Portable IA) when being connected; make electronic installation can read this application program (AP); and then a password is stored in this idle space by application program (AP); when making desire that memory card is read data stored in its data storage block; must import correct password earlier; make application program (AP) that memory card is deciphered and unblank, could be in the data storage block access data, reach the purpose that memory card can be protected data.

Embodiment
Safeguard mechanism for record card of the present invention; see also Figure 1 and Figure 2; (Memory Card) is divided into more than one data storage block 11 with a memory card 1; and use one of them data storage block 11 to store application program (AP) 111; and be provided with an idle space 112 in each data storage block 11; can utilize an electronic installation (as Portable IA) 2 to be connected with this memory card 1; make this electronic installation 2 can read this application program (AP) 111; and then a password is stored in this idle space 112 by this application program (AP) 111; make this data storage block 11 promptly encrypt pinning; so; when desire reads data stored in its data storage block 11 to memory card 1; just must import correct password earlier; 111 pairs of memory cards 1 of application program (AP) are deciphered are unblanked, could be in data storage block 11 the access data.
In the present invention, its electronic installation 2 essential collocation application programs (AP) 111 could be encrypted the work of unblanking with deciphering of pinning to memory card 1.
In the present invention, because memory card 1 (Memory Card) is divided into several data storage blocks 11, and use one of them data storage block 11 to come storage application program (AP) 111, when making memory card 1 on the electronic installation 2 that does not have this application program (AP) 111, use, need use one in addition to store the disk (Floppy Disk) or the laser disc (CD ROM) of this application program (AP) 111, electronic installation 2 also can read application program (AP) 111 in this data storage block 11 in addition, and then carry out this application program (AP) 111, in order to allow the user that proper password is imported, just freedom access data from data storage block 11 can be unblanked to 11 deciphering of data storage block.
In the present invention, see also shown in Fig. 1,2, when electronic installation 2 is connected with memory card 1, can assign the order (201) of data in the access/memory card 1 by an order bus-bar 21, make memory card 1 judge whether this data storage block 11 is to encrypt locking-in state (202), if, then reply one can't access information (203); Otherwise this data storage block 11 that electronic installation 2 gets final product in 23 pairs of memory cards 1 of mat one data bus carries out the access (204) of data.
Moreover, when electronic installation 2 is connected with memory card 1, and read application program (AP) in the self-application program area block 11 at 111 o'clock, can assign by the data storage block 11 in 21 pairs of memory cards 1 of order bus-bar and encrypt the order (205) of pinning, make memory card 1 judge that whether this data storage block 11 is for encrypting locking-in state (206), if then reply the information (207) of a mistake; Otherwise, be about to the password that the user inputed, be stored in the idle space 112, memory card 1 is become encrypt the state (208) that pins.
In addition, when electronic installation 2 is connected with memory card 1, and in data storage block 11, read application program (AP) at 111 o'clock, but the data storage block 11 in 21 pairs of memory cards 1 of mat order bus-bar is assigned the order (209) that deciphering is unblanked, make memory card 1 judge whether password that the user inputs is correct password (210), if, then these data storage block 11 passwords are decrypted and unblank (211), make electronic installation 2 can be from this data storage block 11 access data freely; Otherwise, reply the information (212) of a mistake.
The above only is the best specific embodiment of the present invention, and only structure characteristic of the present invention is not limited thereto, and anyly is familiar with this skill person in field of the present invention, can think easily and variation or modification, all can be encompassed in the claim of this case.
