I-Photoshop isebenzisa i-algorithm engaqondakaliyo ukuze imifanekiso yebhanki ingavulwa

Ukuba ngesizathu esithile nangaliphi na ixesha sizamile ukuvula umfanekiso webhanki nge Inkqubo yoyilo lwegraphic Photoshop, Siza kudibana nesimanga esingathandekiyo. Isizathu soku inokuba kungenxa yokuba le nkqubo ithumela isilumkiso esingavumeli ukusebenza ngemifanekiso enento yokwenza nemali.

Kungenxa yokuba kwiFotohop, ialgorithm yaziswa kuhlobo lwayo lwe-CS ekwaziyo ukubona imifanekiso enereferensi kwingqekembe. Kule nqaku siza kuchaza ngokweenkcukacha ukuba kutheni i-Photoshop isebenzisa i-algorithm engaqondakaliyo ukuze imifanekiso yebhanki ingavulwa.

Ukuba nangaliphi na ixesha singene kule mpazamo, siya kuqaphela ukuba le nkqubo isibonisa i-URL esiyalela ukuba sazi ulwazi ngakumbi malunga nokuwww.kwiebruusa.org). Le webhusayithi yeyakho Iqela leCentral Bank Deterrence okanye okwaziwa sisibizo sayo esithi CBCDG, eli liqumrhu elibandakanya iibhanki eziphambili ezingama-27 kwaye zijolise kumlo wokulwa nomgunyathi wedijithali wemali.

Ukongeza, banoxanduva lweenkqubo ezinje nge I-Photoshop, iCorel Draw okanye iPaint Shop Pro, unale nkqubo yokufumanisa ngaphandle kokuba abaqulunqi beenkqubo ngokwabo banalo naluphi na ulwazi malunga nendlela eyiyo i-algorithm abayinikiweyo isebenza ngayo. Kunyaka wama-200 yayilixesha apho iFotohop yamkela le nkqubo okokuqala, umphathi wemveliso wenkampani yeAdobe ekubhekisele koku njenge indlela yebhokisi emnyama, apho umxholo onayo awaziwa.

Xa umphathi sele ekhankanyiwe ebuzwa malunga nesizathu sokuphumeza le algorithm, uphendule wathi “Njengenkokheli yentengiso kunye nabemi abalungileyo, kubonakala ngathi senza into elungileyo”. Ewe kunjalo, ngokomthetho ithi abaphuhlisi abanyanzelekanga ukuba babenakho ukuphumeza ulawulo olunje, kodwa bathathe isigqibo sokusamkela esi sicelo kwi-CBCDG kwaye bayifaka.

Kwenzeka okufanayo nakwabanye iinkqubo zoyilo lwegraphic.

Ekuqaleni kwakucingwa ukuba ialgorithm yenzelwe ukukhangela iphethini ethile kunye nolungiselelo olufana ncam neqela le-Orion, yiyo loo nto le patheni yaziwa njenge-constellation ye-EUrion, kuba ngokubanzi onke amaphepha ebhanki anepateni yamanqaku amahlanu.

Umphandi UMarkus Kuhn, Nguye owafumana ipateni ngamathuba ngo-2002, xa wayeqhuba ulingelo esebenzisa umshicileli omtsha weXerox, othi Walile ukukwazi ukuprinta itikiti. Imiqathango yokuba la manqaku mahlanu kufuneka abhaqiwe ayisiyimfihlakalo, watsho uKuhn kudliwanondlebe kutshanje, ukuba umfanekiso umbala omnyama nomhlophe, ialgorithm ayifumaneki, kodwa ukuba kufunyenwe uhlobo oluthile lombala, inokufunyanwa.

Ngale ndlela, umgama onokubakho phakathi kwenqaku ngalinye nawo awaziwa kwaye le yenye inkcukacha ethathelwa ingqalelo.

Kwabaninzi, amakhonkco e-omron zizinto ezenza ukuba iPhotoshop yazi xa kufikwa kumfanekiso webhili, kodwa impendulo koku ngu-Hayi okanye ubuncinci ayisiyiyo kuphela inkqubo eyenzayo. Umphengululi weYunivesithi yaseLondon uSteven J. Murdoch wenze iimvavanyo nge Ivenkile yeFotohop kunye nePeyinti Kungekudala emva kwezi nkqubo idilesi yealgorithm. Ukumangaliswa kukaSteve, nje ukuba amakhonkco eenkwenkwezi agqityiwe, iinkqubo zazisakhangela umthetho oyilwayo kwaye umfanekiso wawungenakuhlelwa.

Kolu vavanyo, kwafunyaniswa ukuba i-Photoshop kunye nePSP algorithm yayineziphumo ezifanayo.

Ngaphandle koko, ixesha lokubuyisa impazamo laxhomekeka kumfanekiso owawucazululwe kwaye kukuthi xa usenza lonke olu vavanyo kunye nophando, u-Murdoch waqinisekisa ukuba inkampani ye-Diginarc yenzile Inkqubo esezantsi evumela ukufunyanwa kweebhanki.

Ukuqukumbela, i-Photoshop isebenzisa i-algorithm engaqondakaliyo ukuze imifanekiso yebhanki ingavulwa, ngenxa yokuba yenziwe ngenxa yezizathu zokhuseleko. ukwenzela ukuba ii-banknotes zingabinakho ukwenziwa ngokwamanani.
