Kungani I-Paper Yokusecurity Ayidinga Ukufakwa Kwamabhalo Okugcina Isiqu

Ngokukhulumela imibhalo yasekhaya njengezindaba zokufundwa, imibhalo yezinstituthi, nokuthi kuyini imibhalo yokuthi isithembiso sika-Authenticity, ubunzima bezokugcinwa akabikho phakathi kweminye yezindaba ezizwa ngazo. Uma lezi zimbhalo azikwazi ukugcinwa kahle, kungakwazi ukudala okungafanele noma ukusetshenziswa okungafanele. Ukubeka i-watermarking kuyisikhundla esihlukile kakhulu futhi esifanele kakhulu ekugcinweni imibhalo. Ukubeka i-watermarking kuyisikhundla esikhulu kakhulu kumsebenzi wokugcinwa imibhalo eyodwa emhlabeni ephakeme.

Ukugcinwa okufihliwe okuphambili kokuqondwa

Amawatermark ayisikweli sokubona ngokwesibonelo. Kuyabonakala uma imibhalo ibonwa ngokusebenzisa umthwalo wokubona noma ngokubona ngokujabula kwezindlela ezithile. Lokhu kucacile kakhulu kusukela kuzokwenzwa ngokusebenzisa amasikandha nezinkhishimela ezinhle. I-watermark eyenziwe ngokwempilo yilapho iyagcinwa emhlabeni ngokwakhiwa kwayo. Ngakho, akakwazi ukusikandhwa noma ukubhala ngokusebenzisa izinkhishimela ezinamandla kakhulu.

Izindaba zokuvimbela izindaba zokusekwa kwezinkambo ziyadulwa ngokusebenzisa indlela eyodwa eYiko. Singakwazi ukudala nokuhlela isithunywa sokubhala kwakho, izinhlobo noma amagama. Isithunywa siyisiphumo esibonakalayo sesikhumba futhi asikwazi ukususwa, ukusukwa noma ukubhishwa ngabafundi abanqamuka. Lokhu kusivimba izindaba zokufunda, izindaba zokufunda noma zinye izindaba eziningi zokusekwa kwezinkambo okuphambili kuzoba zilungile.

Ukuvumela okusha kokubona ngokushesha ngaphandle kokusetshenziswa kwamathuba okusebenzisa amathuba okusebenzisa amathuba

Ukunconywa kuyisibonelo esiningi sokuvimbela. Isithunywa singavumelwa ngokushesha ngokuthi ubheka indaba ngaphansi kwesibonelo sokuhlaza noma ukuthi uthathe indaba futhi uqonde ngaphansi kwesibonelo sokuhlaza, ngaphandle kokusetshenziswa kwesigwinya sokubonisa, isibonelo sokuhlaza noma isihlombe sokubonisa QR. Lokhu kusenza isithunywa sikhulu kubazwe besebenza njengamashule, izwe noma izimpahla ezinamandla okuvumela izindaba zokubhala nezindaba zokusekwa kwezinkambo ngokushesha.

Ngaphandle kwalokho, ukuphepha okuyingqikithi okuhlanganisa ama-UV fluorescence namakhodi e-laser kanye nohlelo lukaYiko lwe-watermark. Isizathu sokubheka uphawu lwamanzi njengokuvikelwa kokuqala ukusebenza kwalo ngokuzimela. Njengoba kungadingeki imishini ekhethekile noma izisebenzi eziqeqeshiwe, ngisho nezikhungo ezinkulu zingahlukanisa kalula amakhophi angempela emibhalweni yamanga njengoba iziqu eziningi, amadiploma, neminye imibhalo ingahlolwa ngokuphumelelayo ngemizuzwana nje embalwa.

Ukuhlanganiswa Nezici Zokuphepha Ezithuthukisiwe

Ukuphepha kokubeka uphawu lwamanzi kungathuthukiswa uma kuhlanganiswa namasu okuphepha athuthukile. Idokhumenti yokuphepha ingaba nezimpawu zamanzi ezibonakalayo nezifihliwe kanye nezinye izici zokuphepha njengokuphrinta okungabonakali noma izintambo zokuphepha eziqhakazayo. Nakuba idokhumenti ingase ibe ne-watermark ebonakalayo nengabonakali ngaphansi kwezimo ezikhethekile zokukhanya, lapho kuhlanganiswe izici eziningi zokuphepha kuba nzima nakakhulu ngabanembi bamanga ukuba baqambe amanga.

Ku-Yiko, sisebenzisa ukubeka isithombe esihlukene (watermarking security) ngokwengeziwe ngezinye izindlela njengezindlela zokubona izihlobo (holographic threads), inkhawulo engeyona yodwa (optically variable ink), amalabeli okukhula (tamper-evident labels) kanye nezinye ngokwenza izindikimini zokuphatha ngokuphelele. Isithombe esihlukene esifanana nokuthiwa kwe-university seal singabekwa kwindikimini ngokwengeziwe nalamalabeli okubeka izihlobo (hologram transfer label) kanye nezinhlobo zokuphatha ngokuphelele (fluorescent security fibers). Izinkambo zokuphatha ngokuphelele zizokwakha kahle kusenye, futhi uma isithombe esihlukene esinye sibuyiswe, izinkambo ezingaphansi zizokhula ukuthi indikimini iyisikhali. Ngokwesivinini esiphakeme kune-200,000 ngosuku, uyatholakala ukuthi iphepha lokuphatha ngokuphelele liyenzelwa ngokuphelele, ngokuphakeme kanye ngokuphakeme, futhi ngokwesikhundla esikhulu.

Ukuphatha ngokuphelele kwezindikimini zokuphatha ngokuphelele

Izindaba ezikhulu zezincwadi zokuphatha, njengezincwadi zokuthuthukisa noma izincwadi zokuthi ukuthi isithombe sivumelwe kufanele zilondolozwe ngeminyaka eminingi futhi zilahlekwe ukuze zibe yizinto eziphelele. Izinkampani zokuvikela ezibhalwe ngaphandle kwesipho, zingafihla noma zingabhekwa kahle. Amashini, kanti, ayisakhiwe kusipho futhi angathola ubuchule bakho nakwezinyanga eziningi. Ngempela, kungangathola ubuchule bakho njengoba incwadi yena.

Ku-Yiko, sizakha isipho sesikhundla sokuvikela ngokusebenzisa izinhlelo zokuvikela ezinamandla okukhetha ukuthi isipho siyakwazi ukubona isikhundla sakho, nokubhala kulo, ngokugcina amashini ngendlela efanele kusipho. Isipho esineshini esishicilelwe kuso noma isipho sesikhundla sokuvikela singasetyenziswa ngokubhala ngokubhala ngokusho, ngokubhala ngolwazi olunye, noma ngokubhala ngokusho lwesifuba. Amashini angakunciphisa ukuthi isipho siyakwazi ukubona ngokucacileyo. Izincwadi zokuthuthukisa zemfundo, izincwadi zokuthi ukuthi isithombe sivumelwe, nezinye izincwadi zokuthi ziyizinto ezikhulu zingasebenza kuzo izikhumba nezinkokhelo.

Ukuvikela okunconywa ngokuphelele kubantu abanamandla okukhulisa izincwadi

Uma uthatha ukuthi uthengisa amakhadi nezindaba eziningi kakhulu ngonyaka, izindlela zokubeka isibonelo sokugcina ngokwesilinganiso kuyisidingo esikhulu. Ukubeka isibonelo sokugcina (watermarking) akadinga ukuphrinta okunye okugcina noma isistimu yokuvavanya ngokwelektroniki kodwa kusinika ubukhulu bekhono lokugcina kwenye yezindaba. Ngokulingana nochip ye-RFID nokulaminate okuhologram, izindlela zokubeka isibonelo sokugcina kanye nezinga leyo kuzindaba zakho zokugcina ziyinkani.

Yiko isinikeza izinto zokugcina eziphezulu ngemali engeyona, njengokuphrinta okugcina okwamanzi (watermarked security paper) kuzindaba zokufanele zonke, okunakekela amakhadi angu-80 million ngonyaka, nezinyathelo zokuhologram nezinyathelo zokugcina ze-RFID. Sizakwazi ukusebenzisa bonke abaprofesi besebenzisa izindaba zokufanele njengamashule, amakhasi, nabaphathi bakwezwe ukuthi bazivavanye izindaba zokufanele futhi bazilindele ukuthi bafakelwe amakhadi akhulu abo ngemali encane kodwa ngokukhulu kokugcina.

Isiphetho

Ukufaka isithombe esikhanyeni, na kungakho isikhondlo esisha noma esidala, sikhona ngokwanele njengendlela engezansi kodwa enethembekelo eliphezulu ukulinda izindaba. Kusenziwa indima yokuqinisa ukulinda izindaba ukungafakiwe kuzo ngamaphutha. Le ndlela ibonakala ngokuthi kufakwa isilayela esifihlile ekuphileni, okungasibonakali ngokushesha ngaphandle kokusetshenziswa kwemikhono eminingi noma abasebenzi abaqinisekile. Ngaphezu kwalokho, amasithombe asikhanyeni ayisisekelo esingahlanganisiwe ngokushesha nezinye izinhlayo zokuphrinta, okwenza kubo ubukhona bokulinda nokuncitshwa kwezindaba, izikhiphini, amakhadi okulinda futhi amakhadi okulanda.
