Isiginali ithole i- umjovo omkhulu wenhlokodolobha muva nje futhi ezinyangeni ezimbalwa ezedlule sibona ukunyakaza okuningi ngezibuyekezo ezintsha. Enye yezinto ezintsha ayitholakali kahle futhi ikhona ipiss ejwayelekile yaleyo protocol yokuphepha ye-PIN.
Uhlelo olusha lwe-PIN iphoqa abasebenzisi ukuthi bayidale eyodwa bese bayifaka kaningi ngenhloso yokugcina iphrofayili yakho ebetheliwe, oxhumana nabo nezilungiselelo efwini. Eqinisweni, sebevele benza imanifesto bethula isikhalazo sabo sokuthi iSiginali izobhekana nayo.
Ukukhathazeka kuza ngoba Isiginali ayikuchazi kahle ukusetshenziswa nenhloso yaleyo PIN enomgomo wokugcina leyo datha ibhalwe efwini. Okusho ukuthi, uhlelo lokusebenza alunakekeli kunoma iyiphi incazelo ehlobene nokusetshenziswa kwale PIN entsha ukuphatha leyo datha.
Ukuze siqonde, le PIN ayisetshenziswanga ukufinyelela kuhlelo lokusebenza. Idalwe ngokusetshenziswa okubili engqondweni. Enye yazo ingakhethwa futhi isetshenziselwa ukuthi uma othile ethola inombolo yakho yocingo bese uzama ukuyibhalisa ngeSignal, izovinjelwa izinsuku eziyi-7 ngaphandle kwe-PIN.
Ukusetshenziswa kwesibili kufana ne- ungqimba wesibili wokuphepha wedatha egciniwe kumaseva we-Signal. Sesiyazi ukuthi bathatha ubumfihlo nokuvikeleka kwedatha yomsebenzisi ngokubaluleke kakhulu. Ukunikeza isibonelo salokhu kusetshenziswa kwesibili. Okwamanje uma usebenzisa uhlelo lokusebenza lwedeskithophu futhi uhamba izinsuku ezimbalwa ngaphandle kokuhlola imilayezo emisha, kungathatha imizuzu embalwa ukuthi ivumelanise ukukhombisa okusha. Ngenxa yale PIN, ingakhonjiswa ngokushesha ngaphandle kwalokhu kubambezeleka kwemizuzu.
Njengomunye umsebenzisi ophawula, inkinga ilele kakhulu ekuqambeni le khodi njengePIN futhi lokho kudida abasebenzisi. Sizobona ukuthi ngabe iSiginali isethula isitatimende noma ifuna indlela yokwenza ngcono lolu hlelo olusha lokungeza ukuphepha okwengeziwe kulolu hlelo lokusebenza lokuthumela imiyalezo.
