Description
Technical field
The present invention is a kind of portable access device and access method of tool function of keeping secret, especially refer to have the made access device of storer, can not need under the state of install driver in main frame, the block that storer is cut apart is done the portable access device of maintaining secrecy and moving.
Background technology
Flash memory, since coming out with low power consuming, non-volatile, shatter-proof, the characteristic that high storage density etc. are charming, in many portable devices, gradually replace EEPROM or battery powered storer, more owing to present semiconductor technology progresses greatly day by day, the storage density of flash memory has the growth of advancing by leaps and bounds especially with transmission speed, therefore flash memory more can replace traditional Storage Medias such as hard drives in many application, because flash memory is in above-mentioned all multi-functional and characteristic, relevant dealer utilizes flash memory then and develops and flash memory, and this kind flash memory makes the consumer data can be stored in flash memory apace, and the data that reads flash memory apace, and can carry data easily, the convenience that it brought makes its storage device more traditional than major part (as: rigid disk etc.) have bigger advantage, therefore, flash memory promptly has been subjected to consumers in general's favor since coming out, and becomes a kind of indispensable tool using that is almost.
In addition, a kind of in conjunction with USB (Universal Serial Bus USB (universal serial bus)) and be Portable, vast capacity, the storage facilities that high transmission speed and volume are little is arisen spontaneously, be rigid disk and the made Portable hard disk of transmission interface in conjunction with notes type compute machine or desktop counter, a large amount of uses of its Portable hard disk can revert to the basic side of counter framework, capacity at rigid disk, aspects such as transmission speed, be the most powerful in the storage facilities always, and combine with transmission interface form the Portable hard disk after, more improved the use capacity of Portable storage facilities, to the capacity more than tens of GB of Portable hard disk, make the Portable storage facilities can store simple file file from the not enough 10GB of carry-on dish or memory card, music file is to the multimedia images of a few hours or operating system software etc.
As from the foregoing, the storage device of this type of flash memory or hard disk is because of the little stolen easily or loss of volume; so; promptly there is relevant dealer to utilize password or fingerprint characteristic to protect stored data in the flash memory,, do not worry that also data can be stolen even the user loses storage device.Yet, the memorizer memory devices of the present tool function of keeping secret of selling on the market, all must plug-in driver in the main frame that memorizer memory devices institute desire connects, make the user except carrying memorizer memory devices, also must carry the discs of tool driver in addition, just can on All hosts, use.
Moreover; the memorizer memory devices of above-mentioned tool function of keeping secret; can only do the action of enciphering/deciphering at particular category or archives; the data that the user must will protect is positioned over this catalogue; and can't do secret to whole disk block; the user must be subject to many limitations when using, and can't manage the data that needs by maintaining secrecy arbitrarily, cause the inconvenience in the use.
Thus, how to solve the shortcomings and deficiencies of above-mentioned prior art, be the relevant manufacturer that is engaged in the industry and desire most ardently the direction place that research improves.
Summary of the invention
Fundamental purpose of the present invention is to provide a kind of portable access device and access method of tool function of keeping secret, this access method is the authentication procedure that stores in the first application program block that utilizes storer to cut apart, whether contrast user's identity identical with user's identity in the hidden blocks, can do not stolen to guarantee data stored in the confidential data block by the user that non-authenticated program is approved, allow the unrestricted data that will maintain secrecy of user be positioned in the same block, and must be in main frame when using configuration driver, use to make things convenient for the user.
According to above-mentioned purpose, access device of the present invention is provided with connecting interface, and connecting interface is connected with microcontroller and storer in regular turn, and storer is cut apart hidden blocks, the first application program block, not confidential data block and confidential data block, and the first application program block stores authentication procedure.In addition, the storer of using in this access method is further cut apart the second application program block, and this second application program block stores changeover program or application program.
Access method of the present invention is; When the user utilizes connecting interface and main frame to be electric connection, this access device is set at the use block with the first application program block and confidential data block not, and the confidential data block is set at inactive block, allow the user carry out data access to confidential data block not, and when user's desire is carried out data access to the confidential data block, must carry out the stored authentication procedure of the first application program block earlier, and when carrying out authentication procedure, this authentication procedure can require the user to import user's identity, and authentication procedure can user's identity that identity that the user imported and hidden blocks is stored be done a contrast, after contrast meets the requirements, the confidential data block can be set at the use block, can not stolen by the non-user who is approved through the cipher authentication program to guarantee data stored in the confidential data block.
Below with reference to accompanying drawing and preferred embodiment of the present invention its feature and function are described in detail, in order to understanding fully.
