Fingerprint reader senzira yekuratidza unoshandisa

Kusvika parizvino, kombiyuta yevanhu inoita kuti zvive zvakafanira kutsvaga nzira dzakasiyana dzekudzivirira kuwana ruzivo rwakachengetwa pamakombiyuta. Uye urongwa hwemvumo uye kushandiswa kwevashandi nephasiwedi ndeimwe yezvakanyanya kufanana, kunyange ine zvikanganiso zvizhinji. Imwe nzira yekudzivirirwa kwepaseti inogona kunge yakagadziriswa yakavakirwa pamiganhu yebhayometri yomushandisi, kunyanya neminwe yeminwe. Uye izvi zvinongoda kungoita minwe-seni uye software inobvumirana iyo inouya nemutambo.

Chii chinonzi fingerprint scanner ?

Muverengi weminwe iyi chinhu chinoverenga chimiro chemunwe nezvose zvayo zviri mufananidzo wepapapillary uye inotuma mugumisiro wekutsvaga pane software. Chimwe chikumbiro chakasiyana chinofananidza chigumisiro chinoguma nemuenzaniso wakagadzirwa munguva yechiometric password password yechikamu.

Mitemo yeminwe yemapeji

Mifananidzo yose yeminwe, iyo ikozvino inoshandiswa, inogona kuiswa muzvikamu zvitatu zvichienderana nemamiriro ekushanda:

- semiconductor (silicon);

- optical;

- ultrasonic.

Semiconductor scanners

Icho chinyorwa che scanner chinowana mufananidzo wakabva pane zvidzidzo zve semiconductors, izvo zvinosiyana munzvimbo yekubatana pakati pepapillary pattern uye scanner. Pachikonzero chemhando iyi yekutsvaga michina inogona kutora teknolojia yakawanda:

- Capacitive scanners. Basa rema scanners akadaro anobva pamigumisiro apo kukwanisa kwepn junction mumutambo we semiconductor inoshanduka apo mabhuku epapillary pattern uye yezvinhu zvematrix semiconductor vari kusangana.

- Inonzwika kuzvinopisa zvinokonzera. Chimwe chinhu chinonzi fingerprint scanner chemhando iyi chinoshandisa matrix chaiwo epiezoelements mubasa rayo. Apo munwe unobata matrix, zvikanda zvinomanikidzira pamusoro pacho, uye masango, maererano, kwete. Kubva pakamanikidzwa kunoshandiswa kune matrix, mufananidzo unoumbwa.

- Thermo-scanners. Kuongorora mafaira emhando iyi kunoshandisa masero ane maprojekiti. Aya ma sensor akagadzirisa kusiyana kwekushisa, ndokubva achinjwa kuti ave mhepo.

- Radio frequency scanners. Matanki emhando iyi anosanganisira micro-antenna dzinoita zviratidzo zvisina simba, uye mifananidzo inogadzirwa yeminwe inoitwa kubva pamagumisiro echisimba ekupikisa mapurisa.

- Dzorera zvinotyisa zvinokonzera. Izvo zvakafanana ne thermal scanners. Misiyano chete ndeyokuti munwe inofanira kutorwa pamwe nekushamba kwepamusoro, uye isina kuiswa.

- Inogadzirisa broaching scanners. Inyanzvi yekuwana chimiro chemufananidzo wepapillary yakangofanana neye capacitive, asi nzira yekugadzirwa inopesana pakuti munwe unotorwa pamwe nekushamba kwepamusoro.

- Radio frequency scanners. Nheyo yekushandiswa kwezvigadziri izvi zvakafanana neyero mafaira eredhiyo, asi nzira yekubvisa mifananidzo haisi kushandiswa kwemunwe kune imwe, asi pakutakura munwe pamwe chete nechokumusoro.

Optical scanners

Chimwe chinhu chinonzi fingerprint scanner chemhando iyi inogamuchira mufananidzo weunwe neyo nzira yekuona. Kushanda kwezvigadzirwa zvemhando iyi kunobva mumhando dzakasiyana-siyana

- FTIR scanners. Izvi zvinoshandisa chiitiko chekufungidzirwa kwemukati kunoparadzaniswa.

- Fiber-optic scanners. Muverengi weminwe inonzi optical fiber matrix, fiber imwe neimwe ine photocell.

- Electro - optical scanners. Mufananidzo wacho unowanikwa kubva kune electro-optical polymer, iyo inenge yakagadzirwa ine chiedza-emitting layer.

- Optical broaching scanners. Rudzi urwu rwezvigadzirwa ndiko kugadziridzwa kwezvigadzirwa zve optical umo iwe unoda kutora munwe kumativi ose kuti uwane mufananidzo, uye kwete kuishandisa.

- Roller scanners. Kuti uwane mufananidzo, iwe unofanirwa kuvhara munwe wako pamwe chete nemupumburu, uko zvigunwe zveminwe zvine mapepa emapepa zvinotorwa.

- Contactless scanners. Munwe unotaridzwa nenzira isina kufanira. Munwe unoshandiswa kumugodhi umo unobatidzwa nemitemo yakasiyana siyana, uye iyo yakavakwa mukamera inotora mufananidzo wemunwe.

Ultrasound scanners

Iko rudzi rwechigadziri runotarisa pamusoro pemunwe nemafungu ekudzivirira, uye zvichibva pamakiromita akaenzana emafungu anoonekwa kubva mumipata uye kuputika, mufananidzo unogadzirwa. Rudzi urwu rwechigadzirwa rwakasiyana neavo ruchakurukurwa pamusoro apa kuti mugumisiro wekutsvaga unowanikwa zvakanyanya.
