Iyi ndi njira yapadera yotsimikizira wogwiritsa ntchito, chifukwa chakuti mungathe kusiyanitsa anthu weniweni kuchokera ku kompyuta bots, ndiko kuteteza tsamba la intaneti kuchoka pa spam.
Kapcha - ndi chiyani?
Mawu akuti "captcha" (akugogomezera pa syllable yoyamba) amachokera ku chidule chachingerezi cha Chingerezi - CAPCHA - ndipo amatanthauzidwa kwenikweni ngati mayeso a Turing ambiri omwe amadziwika bwino (mmodzi wa apainiya a sayansi) zomwe zimapangitsa kusiyanitsa makina kuchokera kwa munthu. Captcha ndi mauthenga apadera a makompyuta omwe ali ndi zolemba zosawerengeka ndi zosawerengedwa - makalata, manambala, zithunzi, kuti aziteteza ogwiritsira ntchito ndi kuteteza malowa kuchokera ku spam (bots) komanso kuchoka.
Kodi captcha pa kulembetsa ndi chiyeso chapadera chomwe chimathandiza kusiyanitsa munthu amene akufuna kulembetsa pa webusaitiyi, kuchokera ku spammer amene akufuna kulemba pazomwe zili mzere, kuti apange makalata oyenera. Polemba ndi utumiki, wogwiritsa ntchitoyo ayenera kulowetsa owerenga ovuta kuwerenga mu mawonekedwe apaderawa pansipa.
Ndichifukwa chiyani ndikusowa CAPTCHA?
Kapcha pa malowa amaperekedwa kuti ateteze malo kuchokera ku mapulogalamu osayenera omwe:
- tumizani malonda okhumudwitsa;
- onetsetsani zofunikira zosavuta ku mapulogalamu osiyanasiyana okuthandizira;
- yesani kusokoneza malowo.
Zimamveka kuti mapulogalamu, omwe akulowetsa mu chithunzi ndi malemba ovuta kuwerenga kapena chitsanzo cha masamu, amapita patsogolo pawo ndipo sangathe kudutsa. Munthu akhoza kusiyanitsa mosavuta zizindikiro zomwe zili pachithunzichi, kaya zilembo zinalembedwa, makalata owoloka ndi mzere, kapena zofanana. Masiku ano, capcha yakhala yovuta kwambiri kwa magalimoto komanso yosavuta kwa anthu. Mwachitsanzo, ntchitoyi ingapezeke mu zithunzi za zithunzi ndi mayina a mumsewu. Ingolani pazithunzi zingapo kuchokera ku angapo.
Mitundu ya captcha
Nthawi zina zimakhala zovuta kuti omvera amvetse nthawi yoyamba zomwe captcha ali, chifukwa pali mitundu yambiri ya ma code, ndipo amasiyana mosiyana kuchokera kwa wina ndi mnzake:
- Chiwerengero cha alfabeti kapena chiwerengero ndi chovuta CAPTCHA, chifukwa malembawo ali olembedwa mosaphunzitsidwa: makalata / manambala ali pamwamba pa wina ndi mzake kapena amalembedwa molakwika kotero kuti sangathe kusokonezeka.
- Zithunzi - apa wogwiritsa ntchito, mwachitsanzo, kuchokera ku zithunzi zisanu ndi zinayi amasankha zomwe zikuwonetsa zikwangwani, magalimoto, zizindikiro za pamsewu. Izi ndi mayeso ophweka kuti mudziwe "umunthu" wa wogwiritsa ntchito, chifukwa muyenera kungojambula zithunzi zomwe mumazifuna. Nthawi zina chithunzicho chiyenera kukonzedweratu kuti chiwoneke bwino (mwachitsanzo, mtengo uyenera kukhala wokhazikika, m'malo mozungulira).
- Capcha ndi zitsanzo - muyenera kuchita kuchotsa, kuwonjezera, kuchulukitsa. Monga lamulo, equation ndi yophweka kwambiri pa mlingo wa 2 + 2, koma pa malo otsekedwa apo pali zitsanzo zovuta kwambiri.
- Mtundu wowonjezereka wazitsimikizirani ndikuyika nkhuku m'munda "Ine sindine robot".
Cholakwika CAPTCHA - ichi ndi chiani?
Ngati wogwiritsa ntchito akujambula zithunzizo molakwika, izi zikutanthauza kuti captcha sanadutse kutsimikiziridwa, ndiye kuti mulowetsenso kachidindo, koma manambala ndi makalata ali osiyana kale. Poganizira kuti kawirikawiri malembawa sangawathandize, chifukwa makalatawo ndi osagwirizana, nambalayi imagwirizana pamwamba pa ina, zimachititsa kuti kukhale kovuta kuŵerenga, ndiye nambala yolakwika imadzazidwa kwambiri, nthawi zambiri ndi ogwiritsa ntchito.
Poika chitetezo, malo ambiri amataya abasebenzisi. Kawirikawiri ndimafuna, pomvera mwachidwi, kusiya ndemanga kapena yankho. Koma pano dongosolo likunena kuti mukufunika kulowetsa ojambula kuchokera pa chithunzichi. Olembawa ndi osaphunzira kwambiri kuti atapanga zolakwika zingapo ndi kutaya maselo angapo a mitsempha, wosuta samangoyesa kusiya malo. Ndipo ena samvetsa chifukwa chake zonsezi ndi zofunika, ndizoti, ndipo zikaziwona, zimachoka pa tsambalo, poopa kuti ndi spam, kachilombo kapena chinachake chonga icho.
Ndibwino bwanji kuti mulowetse captcha?
Kuti musunge mitsempha yanu komanso kuti musadzaze ma code nthawi zambiri, mukuganiza kuti CAPTCHA iyenera kuchitika pogwiritsa ntchito malamulo ena:
- Nambala ndi makalata mu chiwerengero chophweka kapena chilembo cha alfabheti ayenera kulowa popanda malo, makasitomala, nthawi;
- kulowa mkati pang'onopang'ono, kukonzanso zizindikiro zolembedwera kupeŵa typos;
- koma ngati mwachitsanzo palokha mawu awiri akulembedwa kudutsa, ndiye kuti iyenso iyenera kuikidwa;
- zizindikiro za chizindikiro, ngati ziwonetsedwe pachithunzi, ziyeneranso kulowa;
- ngati ntchitoyo ndiyotengera chitsanzo, yankho lokha limalowa mu graph, osati chitsanzo ndi yankho;
- Lembani mosamala ntchitoyi ngati mukufuna kusankha zithunzi zojambula (mwachitsanzo, muyenera kupeza zizindikiro za msewu, ndipo izi sizili zofanana ndi mabotolo omwe ali ndi malonda kapena mayina a mumsewu).
Kodi mungadutse bwanji CAPTCHA?
Pa intaneti pali malonda ochuluka omwe alipo mapulogalamu omwe amadziwika bwinobwino. Ndipo mapulogalamuwa akhoza kuwongolera mosavuta, koma kwa ndalama. Ntchito zoterezi sizingawakhulupirire, chifukwa ndizosadabwitsa kuti munthu adzadziwika ndi zizindikiro kuchokera ku zithunzi za robot kuti atsimikizire kuti munthu uyu si robot. Kwa zaka 17 zokhalapo ndi capcha, pakadalibenso mapulogalamu oyenerera. Ndikuyenera kulowetsa malemba pamanja.

- Zimayendetsa ngakhale ana, chifukwa palibe chovuta mu izi - ndondomeko zokonzanso chabe kapena kuthetsa ntchito zosavuta;
- mwayi wakugwira ntchito kuchokera kunyumba.
Kufuna kulowetsa zilembo za ndalama:
- ndalama zochepa (mu mwezi, ngakhale zikwi zambiri za ruble sizingatheke);
- masomphenya akugwa (ogwiritsira ntchito nthabwala kuti kwa mwezi umodzi wa ntchito yotere mungathe kupeza magalasi atsopano).
