Description
The present invention relates to a kind of mouse, combine finger-print recognising instrument on especially a kind of body, and the fireballing finger print mouse of fingerprint recognition.
Do not open computer in people's life, the work more and more, computer helps us to handle, transmit, storing mass data.Because some special application need occasions, need after data are authorized in the computer, call, therefore people adopt the mode of various data encryptions attempting booting computer, data bank, data file etc. to carry out encryption and decryption, so that satisfy the managerial demand that specific people could use.By keyboard password is set during existing cryptographic means main path.Though this method can play the effect of raising the price to a certain extent, traditional password figure place has been grown, and is not easy to memory, brings inconvenience for the user; It is poor to have lacked confidentiality, and normal easy crack can not play the effect of protection.So the computer peripheral equipment security product that uses fingerprint identification technology is also arranged now.This series products is a kind of to be that the fingerprint identifier connects serial ports of computers etc. separately as separate equipment, or finger-print recognising instrument is set on mouse, become have fingerprint recognition can finger print mouse.In actual applications, when people use mouse, can carry out the signals collecting of fingerprint recognition, so the finger print mouse use is comparatively convenient, and for computing machine, does not increase independently peripheral hardware of device again, integrated level is higher.But no matter existing finger print mouse is fingerprint identifier body construction, or the identification circuit structure, or all there are many problems in the position etc. that is provided with of identifier.For example, the pattern recognition limitation of fingerprint is bigger, and touch-screen generally is an optical profile type or capacitive.Photo-electric is by fingerprint surface optical imagery, and shortcoming is can not discern for dried, moist finger; Condenser type is by the capacitive sensing imaging of fingerprint surface, and shortcoming is for dried, moist finger identification very difficult; And all can not distinguish live body.Substantially can not stop the obscuring of various duplicate of fingerprint.Also complicated in the structure of removing static.Also have data transmission that lead need be set in addition, not only influence environment for use, and operation such as terminal block is also inconvenient.Have, identifier touch-screen window embeds to be provided with just offers open window on mouse body, do not set up parts around the window again.When operating personnel use, to touch-screen to press sense relatively poor, and place the location sense behind the finger, therefore usually be that not know how many fingers placed more suitable, the collection that influence is visual, and then influence the whole structure of fingerprint recognition.
The objective of the invention is to provides a kind of finger print mouse at the deficiency of prior art, and its recognition speed is fast, and is highly sensitive, can realize the identification of the three-dimensional live body corium of fingerprint.
Another purpose of the present invention is to provide a kind of finger print mouse at the deficiency of prior art, and its locations of structures setting meets human efficiency's technical indicator, and conveniently finger is put into the location, thereby improves the efficient of identification.
A further object of the present invention is to provide a kind of finger print mouse at the deficiency of prior art, and it can transmit finger print information by Wireless transmission mode.
The object of the present invention is achieved like this:
A kind of finger print mouse, on mouse body, offer window, window is embedded in the touch-screen that is provided with finger-print recognising instrument, the data processing circuit of finger-print recognising instrument is arranged in the mouse body, touch-screen is an Electric field, the surface of touch-screen is a silica gel thin film, is the micro sensing electrode of discrete setting below the film, and the output of electrode connects the sensing process chip.
The edge of described finger-print recognising instrument touch-screen is provided with the electrostatic prevention induction band, and this electrostatic prevention induction band and touch-screen are electrically connected and an end ground connection.

Described start triggering circuit is one or more diodes, and diode is arranged under the Electric field touch screen electrode.
Described data processing circuit also comprises the electrostatic prevention treatment circuit, the output terminal of its control termination sensing treatment circuit.
The data output circuit of described data processing circuit is a USB interface in the interface of computer.
The data output circuit of described data processing circuit is a wireless type, and its antenna is built-in.
Described touch screen electrode has one or more temperature sensors, and the output of temperature sensor connects the input end of data processing circuit.
The window periphery that described touch-screen embeds can be established positioning body.
Described positioning body is to have the positioning body that elasticity is pressed sense of touch.
The opening shape of described positioning body can meet the shape of human finger.
Window is protruded in the front portion that the corresponding finger fingertip of described positioning body is put into, and the front height of positioning body is higher than the rear portion of respective finger body inlet port.
According to the technique scheme analysis as can be known, the present invention can really realize the finger print data collection of three-dimensional live body corium, gather, recognition speed is fast, and be provided with rational in infrastructure, easy to use, meet human efficiency subject's requirement fully, finger is placed with and significantly presses sense, location sense, has further realized fingerprint recognition process accurately and rapidly.
The present invention is described in further detail below in conjunction with accompanying drawing and specific embodiments.
