Mayelana nalolu hlelo lokusebenza
Isicelo salabo abanezimfihlo.
Umgomo wale phrojekthi bekuwukudala uhlelo lokusebenza lokugcina izithombe olubaluleke kakhulu ekugcinweni kwedatha kuyimfihlo. Ngesikhathi esifanayo, okuvumela umsebenzisi ukuthi akhethe ibhalansi ethambile phakathi kokunethezeka nokuvikela. Uma ucasukile ukuthi uyalandelwa, nyusa isivikelo sibe phezulu. Uma udinga nje ukufihla amadokhumenti abalulekile noma izithombe kumuntu ongahleliwe othola ifoni yakho, sivikela kancane.
Izici ezijwayelekile:
1. Izithombe azitholakali kugalari nezinye izinhlelo zokusebenza; zigcinwa kunkomba yangaphakathi yohlelo lokusebenza enamagama ashintshiwe nezandiso.
2. Ukungena ngemvume kuhlelo lokusebenza kuvikelwe yiphasiwedi futhi kufihlwe ukusebenza njengohlelo lokusebenza lomculo, yebo, uhlelo lokusebenza ngaphakathi kohlelo lokusebenza. Isinyathelo esengeziwe sokuvikela ukuvikela ekufinyeleleni okungagunyaziwe - ngemuva kwemizamo yokufaka engalungile engama-30, uhlelo lokusebenza lusula isitoreji nayo yonke idatha.
3. Uhlelo lokusebenza luthatha futhi lugcine izithombe ngendlela ebethelwe kusetshenziswa i-Advanced Encryption Standard.
Umqondo wokuphepha: yonke idatha igcinwa kuphela kudivayisi yomsebenzisi; i-architecture yeseva yokugcina izithombe zomsebenzisi, ukuhlola kuqala, okhiye, namagama-mfihlo ayisetshenziswa. Kodwa-ke, umsebenzisi ngokwakhe angakwazi ukwabelana ngezithombe ngazo zombili izinhlobo ezibethelwe kanye nezingafihliwe (ngengozi yakhe nangengozi). Thola izithombe ezivela kwabanye abasebenzisi futhi uzisuse usebenzisa ukhiye wokubethela ofanayo.
Izici zokugcina idatha.
1. Ukuhlola kuqala kugcinwa kuhla lwemibhalo lohlelo lokusebenza lwangaphakathi ngesandiso se-.p futhi alubethelwe. Isilinganiso sokubuka kuqala samaphikseli sisuka ku-1x1 px (awuboni lutho) siye ku-100x100 px (okuqukethwe kwesithombe ngokuvamile kubonakala) singakhethwa kokuthi Izilungiselelo.
2. Izithombe zangempela zigcinwa ohlwini lwangaphakathi lohlelo lokusebenza. Uma ukubethela kusetshenziswa, ifayela ligcinwa nesandiso esithi .kk. Uma umsebenzisi ekhethe inketho yokungasebenzisi ukubethela, ifayela lilondolozwa ngesandiso esithi .o. Uma umsebenzisi abelana ngesithombe esilotshiwe, ifayela lesikhashana elinesandiso se-.peekaboo liyakhiwa. Kuleli fomu, ifayela lingathunyelwa nganoma iyiphi indlela efinyeleleka kudivayisi. Uma nje umsebenzisi evala iwindi lokubuka lalesi sithombe, ikhophi esuswe ukubethela iyasuswa kudivayisi. Okusho ukuthi, izithombe ezibethelwe zigcinwa kuphela ngendlela ebethelwe. Umsebenzisi angashintsha izilungiselelo zokusebenzisa ukubethela ngemenyu Yezilungiselelo.
3. Ukhiye wokubethela kanye nephasiwedi kugcinwa kudivayisi ngendlela evikelekile. Ngenxa yezizathu zokuphepha, akwenzeki ukubuyisela ukhiye nephasiwedi. Uma ukhohlwe iphasiwedi yohlelo lwakho lokusebenza, isixazululo esingcono kakhulu ukukhipha uhlelo bese ulufaka futhi. Uma ulahlekelwa ukhiye wakho wokubhala ngemfihlo, ungakha omunye ukhiye ngaphandle kokufaka kabusha uhlelo lokusebenza, kodwa izithombe ezilondolozwe ngokhiye omdala ngeke zibukeke.
Izici zesistimu yokubethela.
Uhlelo lokusebenza lunezindlela ezintathu zokubethela:
1. UKHIYE WOKUBHEBELEKA WANJALO (ibhalansi phakathi kokunethezeka nokuvikeleka). Umsebenzisi uqhamuka noma ukhiqiza ukhiye wokubethela, olondolozwa kudivayisi. Ukhiye usetshenziselwa ukubethela ifayela ngokuvumelana Nezinga Lokubethela Okuthuthukile. Ifayela ligcinwa kudivayisi ngendlela ebethelwe, futhi ngisho nangemva kokuthola ukufinyelela kumemori yedivayisi (noma ukuthola ifayela elibethelwe elithunyelwe kusuka kudivayisi), umhlaseli ngeke akwazi ukufunda okuqukethwe ngaphandle kokhiye wokubethela. Ukhiye ugcinwa kuhlelo lokusebenza ngendlela evikelwe umsebenzi we-hash.
2. UKHIYE WOKUBHALWE OKUGUQUKILEYO. Uma umsebenzisi efaka ukhiye aphinde ahlole ibhokisi elithi "Ungalondolozi ukhiye wokubethela", ukhiye ngeke ugcinwe kuhlelo lokusebenza, kodwa uzocelwa ngaso sonke isikhathi lapho bengena ngemvume. Ukhiye ukhona ohlelweni inqobo nje uma luvuliwe. Izinga eliphezulu kakhulu lokuphepha, nokho, uma ukhohlwa ukhiye omdala, amafayela alondolozwe ngaphambilini ngalo khiye ngeke atholakalele ukubukwa.
3. AKUKHO UKUBELEKA.
Inhloso enkulu yohlelo lokusebenza ukugcina izithombe zakho, amadokhumenti, izithombe ezivela kugalari evulekile zivikelekile emehlweni okubuka nokugetshengwa, futhi uzidlulisele ngokuphephile.

Umqondo wokuphepha: yonke idatha igcinwa kuphela kudivayisi yomsebenzisi; i-architecture yeseva yokugcina izithombe zomsebenzisi, ukuhlola kuqala, okhiye, namagama-mfihlo ayisetshenziswa.

Thola izithombe ezivela kwabanye abasebenzisi futhi uzisuse usebenzisa ukhiye wokubethela ofanayo.
Izici zokugcina idatha.
1. Ukuhlola kuqala kugcinwa kuhla lwemibhalo lohlelo lokusebenza lwangaphakathi ngesandiso se-.p futhi alubethelwe. Isilinganiso sokubuka kuqala samaphikseli sisuka ku-1x1 px (awuboni lutho) siye ku-100x100 px (okuqukethwe kwesithombe ngokuvamile kubonakala) singakhethwa kokuthi Izilungiselelo.

Ukuphepha kuqala ngokuqonda ukuthi onjiniyela baqoqa futhi babelane kanjani ngedatha yakho. Ubumfihlo bedatha nezinqubo zokuphepha zingahluka kuye ngokusebenzisa kwakho, isifunda, nobudala. Unjiniyela unikeze lolu lwazi futhi angalubuyekeza ngokuhamba kwesikhathi.
Ayikho idatha eyabiwe nezinkampani zangaphandle
Funda kabanzi mayelana nendlela onjiniyela abaveza ngayo ukwabelana
Ayikho idatha eqoqiwe
Funda kabanzi mayelana nokuthi onjiniyela bakuveza kanjani ukuqoqwa
