Uyikhipha kanjani imethadatha kufayela
Isingeniso
Imethadatha, evame ukuchazwa ngokuthi “idatha emayelana nedatha,” iwukuthi Imininingwane enikeza imininingwane ngefayela elithile. Inganikeza imininingwane ezicini ezihlukahlukene zefayela, njengedethi yokudalwa kwalo, umbhali, indawo, nokuningi. Nakuba imethadatha isebenzisa izinjongo ezihlukahlukene, ingase futhi ibangele ubumfihlo kanye nezingozi zokuphepha, ikakhulukazi lapho kwabiwa amafayela aqukethe ulwazi olubucayi. Kulesi sihloko, sizohlola ukuthi iyini imethadatha nokuthi ungayisusa kanjani kumafayela uye nayo vikela ubumfihlo nokuphepha.
Iyini iMethadatha?
Uma uthwebula isithombe noma udala idokhumenti, imininingwane eminingi ishumeka ngokuzenzakalelayo ngaphakathi kwefayela. Isibonelo, isithombe esithathwe nge-smartphone singase sibe nemethadatha eveza idivayisi esetshenzisiwe, idethi nesikhathi sokuthwebula, ngisho nendawo yezwe uma i-GPS ibinikwe amandla. Ngokufanayo, amadokhumenti namanye amafayela angase afake imethadatha ebonisa isofthiwe esetshenziselwe ukuwadala, igama lombhali, nomlando wokubuyekeza.
Nakuba imethadatha ingaba usizo ekuhleleni nasekulawuleni amafayela, ingase futhi ibangele ubungozi lapho yabelana ngolwazi olubucayi. Isibonelo, ukwabelana ngesithombe esiqukethe idatha yendawo kungonakalisa ubumfihlo bomuntu siqu, ikakhulukazi uma kwabiwa ku-inthanethi. Ngakho-ke, kubalulekile ukususa imethadatha kumafayela ngaphambi kokwabelana ngawo ukuze uvimbele ukuvezwa okungahlosiwe kolwazi olubucayi.
Ikhipha imethadatha
Ezinhlelweni zeWindows, ungasebenzisa amathuluzi afana ne-ExifTool ukususa imethadatha kumafayela kalula. Ngemva kokufaka i-ExifTool GUI, mane ulayishe ifayela, ukhethe imethadatha ozoyisusa, bese uqhuba inqubo yokususa. Uma seliqediwe, ifayela lizokhululeka kunoma iyiphi imethadatha eshumekiwe, eliqinisekisa ubumfihlo nokuvikeleka lapho labelana.
Abasebenzisi be-Linux bangaphinda basebenzise i-ExifTool ukususa imethadatha kumafayela. Ngokusebenzisa itheminali nokufaka umyalo olula, abasebenzisi bangakhumula amafayela ayo yonke imethadatha, bashiye inguqulo ehlanzekile elungele ukwabelana. Le nqubo iqondile futhi iyasebenza, ihlinzeka abasebenzisi ngokuthula kwengqondo lapho babelana ngamafayela aqukethe ulwazi olubucayi.
Isiphetho
Sengiphetha, imethadatha idlala indima ebalulekile ekuhlinzekeni umongo nokuhleleka kumafayela kodwa ingase ibangele ubumfihlo nokuvikeleka engcupheni uma yabelwa kungaqondile. Ngokuqonda ukuthi iyini imethadatha nokuthi uyisusa kanjani kumafayela usebenzisa amathuluzi afana ne-ExifTool, abasebenzisi bangavikela ubumfihlo babo nokuvikeleka lapho babelana ngamafayela ku-inthanethi. Kungakhathaliseki ukuthi iku-Windows noma i-Linux, inqubo yokukhipha imethadatha ilula futhi iqinisekisa ukuthi ulwazi olubucayi luhlala luyimfihlo.
Kulabo abafuna amathuluzi engeziwe obumfihlo nawokuvikela, izinketho ezifana ne-Gophish ye ukuphinga ukulingiswa kanye nama-Shadowsocks kanye ne-HailBytes VPN yobumfihlo obuthuthukisiwe kufanelekile ukuhlola. Khumbula ukuhlala uqaphile futhi ubeke ubumfihlo kuqala lapho wabelana ngamafayela ku-inthanethi, futhi njalo ususa imethadatha ukuze unciphise izingozi ezingaba khona.
