Ukuvikela amawebhusayithi kusuka kubaduni, izinhlamvu ezimbalwa ezingahleliwe ngesikhathi esisodwa
I-CAPTCHA ukuhlolwa okufakwe ku-intanethi okulula okulula abantu ukuba badlule kodwa kunzima izinhlelo ze-software ze-robotic ukuqedela-ngakho-ke igama langempela le-test, ukuhlolwa okuphelele okuzenzakalelayo kwe-Public Turing ukutshela i-Computers kanye nabantu abahlukile . Inhloso ye-CAPTCHA ukudambisa abaduni nabagaxekile ekusebenziseni izinhlelo zesofthiwe yokugcwalisa ngokuzenzakalelayo kumawebhusayithi.
Kungani ama-CAPTCHA ayadingeka?
Ama-CAPTCHA abavimbeli bokuvimbela ukuxhaphaza amasevisi enthanethi.
Abaqaphi nabagaxekile bazama imisebenzi engekho emthethweni e-intanethi, kufaka phakathi:
Isakaza i-poll ye-intanethi ngokuthumela ngokuzenzekelayo amakhulu empendulo yamanga
I-Brute-force ivula i-akhawunti yomuntu ku-inthanethi ngokuzama ngokuphindaphindiwe amaphasiwedi ahlukile
Ukubhalisela ama-akhawunti wamahhala we-imeyili amakhulu
I-spamming blogs nezindaba zezindaba ezinamazwana amaningi amanga kanye nezixhumanisi zenjini yokusesha
Ukudweba (ukukopisha) amakheli we-imeyili abantu kusuka kumawebhusayithi, ukuwasebenzisa kamuva ekuhlaselweni kogaxekile
Ukuhlambalaza imbewu yezintambo kanye nempendulo emihle ukuze kukhishwe abantu ekulandeleni ukukhokhelwa kwe-trojan
Ukuhlolwa kwe-CAPTCHA kungavimbela ukuhlasela okuningi okuvamile, okuzenzakalelayo ngokuvimbela isofthiwe ye-robot ekuthumeleni izicelo ze-intanethi. Zisetshenziswa ngokuphindaphindiwe lapho abanikazi bewebhu bebengathanda ukusebenzisa ubuchwepheshe ukuvimbela ulwazi lwe-spammy kuqala, kunokuthi bahlanzele lokho okuqukethwe ngemuva kokungeziwe. Abanye abaqhubi bewebhu, isibonelo, gwema ama-CAPTCHA ukunciphisa ukuhlukunyezwa komsebenzisi futhi esikhundleni sokuqaphela ukulungiswa kwemisebenzi ukuze kuskena nokuhlukanisa amazwana asolwa noma ama-akhawunti ngemuva kokudalwa.
I-CAPTCHA isebenza kanjani?
I-CAPTCHA isebenza ngokukucela ukuthi uthayiphe inkulumo ethi i-robot izobe nzima ukuyifunda. Ngokuvamile, lezi zinkulumo ze-CAPTCHA ziyizithombe zamagama aqoshiwe, kodwa kubantu abangaboni kahle nabo bangaba yizici zezwi. Lezi zithombe nokuqoshwa kunzima izinhlelo zokusebenza ezivamile ukuqonda, ngakho-ke, ama-robot ngokuvamile akakwazi ukuthayipha inkulumo ngokuphendula isithombe noma ukurekhoda.
Njengoba ukuthuthukiswa kwamakhono okusebenza okusebenzayo, i-spam bots ikhula ngokwengeziwe, ngakho-ke ama-CAPTCHAs aguquke ngokuyinkimbinkimbi njengempendulo.
Ingabe i-CAPTCHA iphumelele?
Ukuhlolwa kwe-CAPTCHA kuvimbela ngokuphumelelayo ukuhlaselwa okuzenzakalelayo okungavamile, yingakho bevame kakhulu. Abangenazo iziphambeko zabo, kodwa kubandakanya ukuthambekela kokucasula abantu okufanele bawaphendule.
Isofthiwe ye-Re-CAPTCHA ye-Google-ukuvota okulandelayo kwe-CAPTCHA ubuchwepheshe-isebenzisa indlela ehlukile. Izama ukuqagela ukuthi iseshini iqaliswe umuntu noma ibhodlela ngokuhlola ukuziphatha lapho ikhasi lilayisha. Uma kungenakukwazi ukutshela umuntu ngemuva kwekhibhodi, inikeza uhlobo oluhlukile lokuhlolwa, noma "chofoza lapha ukufakazela ukuthi ungumuntu" ibhokisi noma iphazili ebonakalayo esekelwe isithombe se-Google Images noma ibinzana elikhishwe kusuka ku-Google Amabhuku. Esivivinyweni sesithombe, uchofoza zonke izingxenye zesithombe eziqukethe uhlobo oluthile lento, njengempawu zomgwaqo noma imoto. Phendula kahle, futhi uqhubeka; uphendule ngokungalungile, futhi uhanjiswa ngenye iphazili yesithombe ukuxazulula.
Abanye abathengisi banikeza ubuchwepheshe obususa ingxenye "yokuhlola" ye-CAPTCHA ngokunikeza noma ukuphika ukufinyelela kwewebhusayithi kuphela kwezinye izindlela ezihlobene nephethini lokuxhumana kwesikhashana seWebhu.
Uma isofthiwe yokuphepha isola ukuthi akukho muntu oshayela iseshini, iphika uxhumano ngokuthula. Uma kungenjalo, inikeza ukufinyelela kukhasi eliceliwe ngaphandle kokuhlolwa okuphakathi noma imibuzo.
