Description
[technical field]
The present invention relates to a kind of flash memory device, relate in particular to a kind of flash memory device that can realize fingerprint identification function with information display function.
[background technology]
Calendar year 2001, the mobile storage product is shown up prominently on market, has shown its powerful kinetic energy as newly emerging force in fierce day by day PC peripheral hardware competition.Portable hard drive, flash disk and derived product MP3/MP4 thereof etc. have obtained huge development, and sale in recent years is the blowout formula and increases, and a year sale surpasses nearly ten million platform in the world wide at present.
Existing flash memory device generally comprises host connector, the controller that matches with host connector, storage medium and external shell.This controller electrically connects with host connector and storage medium respectively; Because it has that volume is little, capacity is big, zero access, advantage such as easy to carry, therefore to use more and more widely, the technical scheme of this type of mobile memory can be with reference to No. the 00114081.7th, No. the 99117225.6th, Chinese patent and Chinese patent.
Yet, the mobile storage product of present sale, aspect these two of the convenience of using at safety of user data and product, do and imperfection, mainly show:
1, secure user data aspect: present mobile storage product, when the protection user data, often adopt following several modes:
A. the dish lock is encrypted: this mode also is known as password encryption.Be the user before this equipment of use, need the correct password of input earlier.This is the simplest a kind of software cryptography mode, but degree of safety also is minimum;
B. software cryptography: the software cryptography of saying here is meant adopts high strength software cryptography algorithm, as the AES cryptographic algorithm etc.Adopt this mode, level of encryption improves greatly, but the transmission speed of mobile storage product is had very big influence, can significantly reduce transmission speed; On the other hand, for handheld device, need bigger program's memory space, cost increases increasing.
C. hardware encipher: the hardware encipher of saying here is meant that hardware module realizes above-mentioned software cryptography mode with hardware, make the transmission speed of equipment unaffected.
Adopt above-mentioned cipher mode, quality is respectively arranged.The expense that the encryption of dish lock expends is few, realize simply, but security is minimum; The software cryptography meeting greatly influences speed, and the whole cost of product is improved; Though adopt hardware encipher still unaffected in speed, the user still needs to input password, in case password forgets that all data will not exist.
2, product ease of use aspect: the mobile storage product, can be divided into two types at present, a kind of is that product itself is self-powered, as MP3 etc.; Another kind is the not charged source of product itself, needs could use by USB Host power taking, as flash disk, portable hard drive etc.This two series products, the user is difficult to know intuitively the product capacity operating position, all needs to connect power supply, just can check.User's use is caused very big inconvenience.
