Description
Technical field
The utility model provides a kind of external unit that links to each other with computing machine, and it is the novel mouse with finger print identifying.The utility model links to each other with computing machine, controls duty of the present utility model by computer program.When it is placed in the mouse performance state, has the repertoire of common mouse; When it is placed in the finger print identifying duty, can be by the authentication of fingerprint being realized the security protection of computer system.
Background technology
In today of infotech high development, people improve day by day to the reliability of computer safety system and the requirement of convenience, traditional computer safety system is to realize that by the software cryptography mode in the machine this cipher mode easily is cracked, and safety coefficient is not high.Along with high-tech development, people recognize does not have identical fingerprint in the world, and everyone fingerprint all is unique.Based on this specific character of fingerprint, adopt finger print identifying can improve security, the reliability of computerized information greatly.The finger print identifying device arises at the historic moment thus, and they are mainly used in the security protection of special industries such as finance.Manufacturers produce such as Germany Infineon company, U.S. THE ASM GROUP one class finger print identifying device.The product of Germany Infineon company is made of condenser type imageing sensor and interface circuit, behind the imageing sensor picked-up finger print information, send into computing machine, compare with data in the data with existing storehouse by interface circuit, confirmed, and then realized the security protection of computing machine.The finger print identifying device of U.S. THEASMGROUP, its imageing sensor then adopts cmos image sensor, though these two kinds of products have reached the purpose of computer security, but its volume is bigger, costs an arm and a leg, function singleness, and the finger print identifying device additionally takies the interface resource of computing machine, very easily produce with the use of existing general peripheral hardware and conflict, system's resource requirement is huge, and it is complicated to cause computer system to constitute thus.
The utility model technology contents
The utility model provides a kind of novel finger print identifying mouse; it with the finger print identifying function with existing computer standard peripheral hardware---mouse function combines; both had computer standard peripheral hardware---mouse function, and had finger print identifying again, reach the function of protecting computer security.
The finger print identifying mouse comprises mouse signal circuit module, USB microcontroller and the USB interface that links to each other with computing machine.The USB microcontroller is connected with USB interface with imageing sensor, mouse signal circuit module respectively.
Imageing sensor of the present utility model can adopt advanced solid state image sensor---CMOS (complementary mos device) imageing sensor, CCD (charge-coupled image sensor) and condenser type imageing sensor.
The utility model is operated under the standard mouse state, possesses all functions of mouse; And under the finger print identifying state, the highest resolution of image can reach CIF 352 * 288, and the fingerprint image certified transmission time is not more than 1 second.And owing to adopt unique power management and noise reduction measure, the signal to noise ratio (S/N ratio) height of image reaches more than the 48dB.
The utility model unites two into one the function of finger print identifying device and the function of standard mouse, only is connected with computing machine by a USB interface, has reduced peripheral hardware quantity, has saved interface resource.The utility model has adopted the USB microcontroller able to programme that cooperates with imageing sensor to replace single control chip in original standard mouse, the picked-up and the transmission of finger print information both can have been finished, can finish the transmission of mouse message again, simultaneously a large amount of information processing works being transferred to computing machine finishes, make volume of the present utility model suitable, and cost is compared obvious reduction with existing finger print identifying device with the standard mouse volume.The utility model is widened the existing range of application that is only applicable to the finger print identifying device of special occasions greatly, can be widely used in the security protection of personal computer.
