Ingabe ikhodi yomhlaba ye-QR izosetshenziswa izikhathi eziyizigidi eziyizinkulungwane ezingu-10 ngosuku?

Ingabe ikhodi yomhlaba wonke ye-QR izosetshenziswa izikhathi eziyizigidi eziyizinkulungwane ezingu-10 ngosuku?

Namuhla, impilo yethu ayinakuhlukaniswa "nekhodi yokuskena iselula". Sidinga ukuskena ibhakhodi lapho siyothenga futhi Ikhodi ye-QR lapho sikhokha. Phakathi nenkathi yobhubhane, sidinga ukuskena ikhodi yezempilo lapho siya futhi sibuya ezindaweni ezihlukahlukene. Ikhodi ye-QR namabhakhodi ahlukahlukene akhona yonke indawo empilweni yethu. Uhlu lwemigqa emnyama nezikwele ezimnyama lungaqukatha kanjani ulwazi olungaka? Zasungulwa kanjani? Ingabe i-ikhodi ye-QR izosetshenziswa ngemva kokubuyekezwa?

QR code isuka ekhodini enohlangothi olulodwa ekufakweni komkhiqizo ojwayelekile, futhi yazalelwa e-Japan ngo-1994. Yaqala ukusetshenziswa e- izinkundla zokuphepha komphakathi, ezempi kanye nezokukhulumisana njengendlela yokuphatha imibhalo yomuntu siqu. Kamuva, yanwetshwa kancane kancane embonini yeposi, yezokuthutha kanye nezimboni zokukhiqiza. Ucwaningo lwekhodi enezinhlangothi ezimbili e-China lwaqala ekuqaleni kwawo-1990, futhi isikhungo sokubhala ama-athikili sase-China siye salinganisa futhi sahumusha amakhodi amaningana avamile anezinhlangothi ezimbili. Ngokukhula kwesidingo sabasebenzisi basekhaya sekhodi enezinhlangothi ezimbili, abasebenzi bethu bezobuchwepheshe bazenzele eyethu izinga lezwe lekhodi enezinhlangothi ezimbili ngesisekelo sokufunda kokuhlangenwe nakho kwamanye amazwe.

Okwamanje, impilo yethu ziya ngokuya zihlukaniseka ekusetshenzisweni kwekhodi enezinhlangothi ezimbili. Inkokhelo yekhodi yokuskena yokuthenga, ukukhuphuka kobunikazi bomngane we-wechat, ukubonisana ngolwazi lomuntu siqu ku-inthanethi, ukuhlonza ikhodi yezempilo yomuntu siqu nokunye. Kulinganiselwa ukuthi bonke abantu basebenzisa amakhodi anezinhlangothi ezimbili eziyizigidi eziyizinkulungwane eziyi-10 nsuku zonke. Uma amakhodi anezinhlangothi ezimbili evuselelwe, ingabe azosetshenziswa aphele?

Isimiso sekhodi enezinhlangothi ezimbili ukusebenza kanambambili, okuyinto noma ubani ofunde ikhompuyutha ayaziyo. Isebenzisa kanambambili u-0 no-1 njengekhodi, ukuma kwamaphuzu amathathu, okumnyama nokumhlophe, okumnyama ku-binary "1", okumhlophe ku-binary "0" ukwenza ikhodi enezinhlangothi ezimbili, imininingwane yokufaka ingahlukaniswa izigaba ezintathu, ulwazi lombhalo. , njengemininingwane yekhadi lebhizinisi; Ulwazi lwezinhlamvu, njengekheli lewebhu nenombolo yocingo; Kukhona nolwazi lwezithombe, ngisho namavidiyo amafushane.

Ikhodi enezinhlangothi ezimbili ehlukile enegridi evundlile neqondile ayifani, encane ingu-21 × 21 matrix, enkulu kunazo zonke ingafinyelela ku-171 × 171。 Isibonelo, ikhadi lebhizinisi lomuntu siqu le-wechat esivame ukulisebenzisa lingu-37 × 37, inkokhelo ka-Alipay yekhodi enezinhlangothi ezimbili incane, okungu-25. × 25. 25 × isibonelo, ngaphandle kokuthi ezinye izindawo ezimisiwe zokuma azikwazi ukushintshwa, amagridi amancane angama-478 ngokwethiyori angakwazi ukwakha amakhodi angu-2 ^ 478 ahlukene anezinhlangothi ezimbili. Uyini umqondo we-2 ^ 478? Uma sicabanga ukuthi abantu abayizigidi eziyizinkulungwane ezingu-7 600 emhlabeni bacindezela ngesikhathi esisodwa ikhodi enezinhlangothi ezimbili esikrinini sikamakhalekhukhwini, umuntu ngamunye uzokwazi ukusula yonke ikhodi yokukhokha ye-Alipay enezinhlangothi ezimbili ngo-10^ izikhathi ezingu-134.

Enye yesayensi Iqembu liye lalinganisela ukuthi isikhathi esisele sokuphila kwendawo yonke kufanele sibe iminyaka eyizigidi eziyizinkulungwane ezingu-140. Uma sicabanga ukuthi umuntu oyedwa uchofoza umzuzwana owodwa, abantu abangaphezu kwezigidigidi ezingu-7 nabo badinga amabhiliyoni angu-3 × 10 ^ 126. Ngamafuphi, akukwazi ukuqedwa, ingasaphathwa ukuthi yi-25 × 25 kuphela.

Kumele kuqashelwe ukuthi ngenxa yokuduma okuphezulu komakhalekhukhwini, abantu abaningi abavamile ukusebenzisa amakhompuyutha ngaphandle kwasemsebenzini, ngakho isofthiwe enonya, amawebhusayithi obugebengu bokweba imininingwane ebucayi namaTrojan asatshalaliswa ngekhodi enezinhlangothi ezimbili. Ngakho-ke, kufanele siqaphele inqubo yokuskena ikhodi yansuku zonke, esikhundleni sokuskena amakhodi anezinhlangothi ezimbili zemvelaphi engaziwa kanye nolwazi lwamakhodi anezinhlangothi ezimbili zabantu abangaziwa.

Ngaphezu kwalokho, lapho sishaya ujenga ukuze sikhokhe ezitolo ezinkulu nasezitolo , abantu abaningi bajwayele ukubiza ikhodi yokukhokha enezinhlangothi ezimbili kusengaphambili, okunikeza ongenamthetho ithuba lokudlulisela imali kumakhalekhukhwini wakhe uma unganakile ukuskena ikhodi ngemuva. Ngakho-ke, lapho uvula ikhodi yokukhokha enezinhlangothi ezimbili, kufanele unake ibanga eliphakathi kwabantu abalayini abangaphambili nabangemuva ngaphambi kokuya kusibonisi esiphephile.
