- I-metadata ye-EXIF igcina ulwazi olubucayi njengezixhumanisi ze-GPS eziqondile, izinsuku, kanye nemininingwane yedivayisi.
- Kukhona amathuluzi endawo kanye nezinhlelo zokusebenza zeselula ezikuvumela ukuthi ususe le datha ngaphandle kokulayisha amafayela kumaseva angaphandle.
- Ukususa imethadatha kubalulekile ukuze kugwenywe ukulandelelwa kwendawo kanye nokuvezwa kwedatha yomuntu siqu lapho kwabelwana ngezithombe.
Cishe uke wabhekana nokulayisha isithombe ezinkundleni zokuxhumana noma ukusithumela nge-imeyili ngaphandle kokucabangela umkhondo ongabonakali wedatha esinayo . Asikhulumi ngemibala noma ukucaca, kodwa ngolwazi olufihliwe oluhamba nefayela futhi olungaveza okuningi mayelana nokuphila kwethu kwangasese kunalokho esingathanda.
Ezweni ledijithali, kulula ukuthatheka bese wabelana ngokuqukethwe ngaphandle kokuqaphela ukuthi sidlulisela ukhiye wendawo yethu noma imodeli eqondile yocingo esilisebenzisayo. Yingakho ukufunda ukuhlanza lawa mafayela kungeyona nje indaba yobuchwepheshe, kodwa kuyindlela eyisisekelo yokuphepha kunoma ubani osebenzisa i-smartphone namuhla.
Iyini idatha ye-EXIF futhi kungani ibalulekile?
Uma sikhuluma nge-metadata ekuthwebuleni izithombe, sibhekisela kakhulu ku-EXIF (Exchangeable Image File Format). Empeleni, uhlobo lwelogi lobuchwepheshe ikhamera elibhala ngokuzenzakalelayo ngesithombe ngasinye. Igcina konke kusukela ekuvulekeni kuya ku-ISO, kodwa idatha eyingozi ngempela ulwazi lwendawo.
Uma ungaqaphile, isithombe esilula senja yakho engadini singaqukatha izixhumanisi ze-GPS eziqondile zekhaya lakho, ezinembile ngaphakathi kwamamitha ambalwa nje. Ngenkathi amanye amapulatifomu ezokuxhumana esusa olunye lwalolu lwazi, izinhlelo zokusebenza ze-imeyili kanye nemiyalezo eqondile zivame ukugcina konke kuphephile, okushiya ubumfihlo bakho budaluliwe ngokuphelele.
Ngaphezu kwendawo, kunedatha yobuchwepheshe nebucayi engaba yingozi. Isibonelo, inombolo yochungechunge yedivayisi ingaxhumanisa izithombe obuhlose ukuzifihla ngqo kuwe, futhi izithonjana ezifihliwe zingaveza uhlaka lokuqala lwesithombe osuvele usinqumile ukuze kufihlwe okuthile.
Izingozi zangempela zokungazihlanzi izithombe zakho
Lokhu akuyona into exakile, kuyiqiniso. Ingozi esobala kakhulu ukulandelwa kwendawo , lapho umuntu onenhloso embi angathola khona ukuthi uhlala kuphi, usebenza kuphi, noma ukuthi uhamba ngayiphi indlela eholidini ngokuhlaziya amafayela akho e-JPG noma e-PNG.
Kukhona futhi ingozi yokuhlukunyezwa noma ukulandelwa . Ngokusebenzisa izitembu zesikhathi nezindawo zezwe, kungenzeka ukwakha kabusha ukunyakaza komuntu. Lokhu kwandiswa yimiphumela engaba khona kwezomthetho , njengoba i-metadata ingasetshenziswa njengobufakazi obungenakuphikiswa bokuthi isithombe-skrini sathathwa kuphi futhi nini.
Izinhlobo zemethadatha ngokusho kwefayela
Akuzona izithombe kuphela ezinale nkinga. Amadokhumenti ehhovisi adalwe nge-Word, Excel, noma i-PowerPoint agcina nezindlela zangaphakathi zamafolda, amagama ababhali, kanye nenhlangano oyingxenye yayo. Uma uthumela ikhotheshini kuklayenti ngaphandle kokuyihlanza, ungase uveze ulwazi lwangaphakathi lwenkampani yakho ngokungazi .
Uma kukhulunywa ngama-PDF, amathuluzi afana ne-Adobe Acrobat Professional akuvumela ukuthi uphathe lokhu kuhlanza. Kulabo abafuna okuthile okunamandla kakhulu futhi okunezinkundla eziningi, kunezinketho ezifana ne- ExifTool , okuwummese we-Swiss Army wokususa idatha ku -Windows nakwezinye izinhlelo , osebenza ngezithombe namavidiyo.
Indlela yokusebenzisa amathuluzi okuhlanza
Uma unquma ukusebenzisa i-EXIF remover yesimanje, inqubo ivame ukuba lula kakhulu. Ngokuvamile, udinga nje ukuhudula amafayela kusiphequluli noma kuhlelo lokusebenza, uhlole ithebula ledatha ukuze ubone ukuthi yini ehlungwayo, bese uchofoza inkinobho yokususa. Okungcono kakhulu, funa amathuluzi akuvumela ukuthi ucubungule amafayela amaningi ngesikhathi esisodwa ukuze wonge isikhathi.
Iphuzu elibalulekile ukwazi ukuthi yini okufanele uyisuse nokuthi yini okufanele uyigcine. Ukuqinisekisa ukuthi isithombe asibukeki sibi, kubalulekile ukulondoloza ukuqondiswa kwesithombe kanye nephrofayela yombala. Okufanele kususwe ama-coordinates, amathegi esofthiwe, kanye nanoma yiziphi izitembu zesikhathi ezisolisayo.
Ubumfihlo kanye nokuphepha lapho kucutshungulwa amafayela
Yilapho okudingeka uqaphele khona kakhulu. Amanye amawebhusayithi akucela ukuthi ulayishe isithombe sakho kumaseva awo ukuze usihlanze, kodwa lokho kuyaphikisana ngokuphelele . Kungani ungathanda ukususa idatha yakho yobumfihlo ngokuthumela ifayela lakho kumuntu ongamazi? Inketho engcono kakhulu ukusebenzisa amathuluzi acubungula konke endaweni yakho kusiphequluli sakho usebenzisa i-WebAssembly.
Ngokufanayo, izinhlelo zokusebenza zeselula ezenzelwe i-iOS noma i-Android ezenza ukuhlanza ngqo kudivayisi ziphephile kakhulu. Lezi zinhlelo zokusebenza ngokuvamile zinikeza inketho yokugcina ikhophi ehlanzekile noma ukufaka esikhundleni sokuqala, ukuqinisekisa ukuthi ulwazi olubucayi alulokothi lukushiye ukulawula.
Ukulawula okuphelele ukuthi ubani obona ukuthi ubukuphi ngoLwesibili olwedlule kubalulekile. Kungakhathaliseki ukuthi usebenzisa isofthiwe ekhethekile, izilungiselelo zesistimu yokusebenza, noma izinhlelo zokusebenza ezizinikele, isihluthulelo ukugwema amaphutha lapho wabelana ngokuqukethwe ku-inthanethi futhi uhlale ubeka phambili ukucubungula kwendawo ukuze izimfihlo zakho zihlale zezakho wedwa.
