Intuthuko yakamuva kanye nokusetshenziswa kobuchwepheshe be-Fingerprint Scanner Technology

Siphila esikhathini lapho amaphasiwedi abhalwe khona. Noma ngabe yizwe, ezezimali zentengiso, uhlelo lwebhizinisi / lwe-JBAN, ikhadi lomuntu siqu noma ukungena ngemvume kwekhompyutha, futhi kuyindlela yokuhlola esetshenziswa kakhulu yokuphepha, kodwa futhi kuyindlela yokuhlola, ukuqhekeka, ukucwilisa, njll. Esikhathini esingapheli Izinkinga, noma ngabe amaphasiwedi aphezulu futhi aphezulu enza abantu bazizwe bephephile, umuntu uzoba nezinkinga ezinjengokudideka kwenkumbulo futhi akhohlwe lapho ebhekene namaphasiwedi amaningi, athola ukuqashelwa kobuso, ukuqashelwa kwe-Fingerprint, ezokubonwa kweminwe Ubuchwepheshe obuvikelekile, obuyimfihlo, nobuchwepheshe obuhle kakhulu be-biometric, phakathi kwabo, yize ukusetshenziswa kokuhlonzwa kweminwe kusekukhohlisweni, kulula ukubalwa futhi kuncishiswe. , ayinakukhonjwa, ngakho-ke, abantu banethemba lokuba nobumfihlo obungcono, ukuthembeka okuphezulu nobuchwepheshe bokuphepha kwezokuphepha okulula kanye nezobuchwepheshe bezithwebuli zeminwe kwangena, kuya ngokuthi imboni ebizwa nge-biometric ephezulu ye-biometric.

Ubuchwepheshe be-biometric be-Finger vein busephephe futhi buthembekile, futhi kuzoba ubuchwepheshe bolwazi lwe-biometric biometric emasimini amaningi ocwaningo.
Uhlelo lokuvinjelwa luqukethe i-Front-End Front-End. I-Front-End ibhekele ukurekhoda nokuqoqa izithombe ezitholakele, bese ingaphinde idle ngokushesha emuva emuva. Ngemuva kokuthi umlawuli wokugcina emuva uthola imininingwane yedatha, enze ucwaningo, ukuhlaziya nokucutshungulwa, futhi anikeze imiyalo ngomthelela wemiphumela. Ukuyalela i-Front-End ukuze wenze imisebenzi, kungukuphela kwempilo okunempilo futhi okuzinzile kwesikhungo somyalo wobuchopho obuhlanganisiwe wokuqina nokuvikeleka kwalo lonke uhlelo.
Idlala indima ebalulekile,
1. Umgomo osebenzayo wokuphela kwangaphambili
I-hemoglobin yamangqamuzana egazi abomvu emithanjeni yegazi yomuntu incishisiwe ye-oxygen, futhi i-hemoglobin encishisiwe ingadonsa imisebe ye-infrared, ngakho-ke lapho imisebe ye-infrared icela ukuboniswa okubuthakathaka, ngaleyo ndlela yakha umthambo obuthakathaka, ngaleyo ndlela akha umthambo obuthakathaka, ngaleyo ndlela akha umthambo obuthakathaka, ngaleyo ndlela akha umthambo obuthakathaka, ngaleyo ndlela wakhe umthambo obuthakathaka, ngaleyo ndlela wakhe umthambo isithombe sephethini, kanye nokusebenzisa okuthize.
Ngokukhipha umunwe ngokukhanya kwe-λ wavelength, isithombe esicacile saso singatholakala, futhi lesi sici sesayensi esibonakalayo singasetshenziselwa ukuhlaziya nokucubungula isithombe esiqoqiwe ukuthola izici zayo zemvelo.
2. I-Backend isebenza kanjani
Isilawuli sokulawula ukufinyelela ngumyalo nokubukwa kwesitoreji kohlelo lokulawula ukufinyelela. Umgomo wayo wokusebenza ukuvikela inani elikhulu lobuchwepheshe bolwazi lwedatha yedatha egcinwe endaweni yokuphepha kwenethiwekhi ezungeze iwashi ngaphandle kokungena ngemvume ngenxa yokuhluleka kwamandla noma ukuhlaselwa kwamandla. , ngaphansi kwesimo sokusebenza kokuqoshwa kwezithombe, kungakwenza ngokushesha futhi ngempumelelo lelo lwazi lokuhlaziya lokuqhathanisa, bese luphakela imiyalo ethile yokusebenza ekhanda lokufunda ngomunwe. Uma ukufakwa kolwazi kulungile futhi kuvumelekile, umfundi azokwenza imiyalo yokuqala. Uma i-EBRICE YOKUTHOLA Iphutha Lokufaka noma Ukuhlukaniswa Okunobudlova, isilawuli sizokwenqaba ukuvula umnyango.
