Izithombe ezithathwe ngama-smartphones zivame ukuba nemininingwane eyengeziwe efakiwe, eyaziwa njenge Metadata. Lolu lwazi lungaba yisisekelo njengesikhathi nosuku lwesithombe, futhi luqonde njengendawo lapho isithombe sithathwe khona, uhlobo lwekhamera, idatha yezemvelo, nokuma ukubala.
Impela, lolo lwazi alunabungozi, kepha kwezinye izimo, imininingwane eyeqile esithombeni esisodwa noma kuvidiyo ingabeka othatha isithombe kalula engozini.
Ubhekene nalesi simo, Iphrojekthi Ye-Guardian, ukuthuthukisa UkuThOngCam, uhlelo lokusebenza lwekhamera olususa imininingwane (imethadatha) ekhiqizwe kufayela ngalinye, ngaphezu kokuthola ngokuzenzakalela nokufiphaza ubuso esithombeni nakwividiyo ngayinye, ukugcina ukungaziwa komsebenzisi.
Manje, ngokusuka kokunye ukubuka, ukukhiqizwa kwale methadatha kungaba wusizo oluwusizo lokuqinisekisa okuqukethwe, ikakhulukazi kulezi zikhathi lapho okwaziwa khona “Ubuntatheli beCitizen”Njalo uma kuthatha indiza ethe xaxa. Konke lokhu kwenza imethadatha ibaluleke manje, uma kubhekwa ukuthi ukuxhashazwa kwedijithali nokuguqulwa kwezithombe kuvamile kulezi zinsuku.
Nakulokhu futhi, iThe Guardian Project iyavela, kepha manje nge IkhameraV, ukusetshenziswa kwe- umthombo ovulekile ukuze Android, kusekelwe endaweni yesikhulumi I-InformaCam. Ongathatha ngayo izithombe namavidiyo, ngokuqinisekiswa kokuqukethwe ngokusebenzisa imethadatha.
Yakhiwa izishoshovu, izintatheli nabameli, inhloso yabo kwakuwukwenza isicelo esivumela ukuthi bathathe ubufakazi obubonwayo futhi bafakazele ukuhlukunyezwa nokuphulwa kwamalungelo emhlabeni jikelele.
IkhameraV Isithwebuli semethadatha, sisebenzisa izinzwa ukuthi i-smartphone yakho kufanele ithole imininingwane yezemvelo, kanye nedatha evela ku-WiFi, i-bluetooth, nakumanethiwekhi weselula, ukuzigcina zihlangene nezithombe ezithathiwe. Ngale ndlela, iCameraV ayitholi kuphela isithombe salokho okwenzekayo, kodwa futhi Thwebula umoya wesithombe noma ividiyo. Lezi zinzwa zingavela ku:
Isi-Movimiento, njengama-accelerometer, avumela ukuthola ukunyakaza okwenzeke ngesikhathi sokurekhoda.
Indawo, ngokusebenzisa indawo ye-GPS, ukuhlinzeka ngezixhumanisi eziqondile lapho isithombe noma ividiyo yathathwa khona.
imvelonjengama-thermometer ahlinzeka ngolwazi lokushisa nedatha ehlobene nesimo sezulu.
Futhi IkhameraV igcina amanethiwekhi we-WIFI namadivayisi we-Bluetooth endaweni yendawo, kufaka phakathi idatha yendawo ngaphakathi kwenethiwekhi yeselula, ukuhlinzeka ngezinga eliphakeme lemininingwane yokuqinisekisa okuqukethwe.
Leli nani lemethadatha libethelwe ngaphansi I-PGP futhi kwabiwa nabanye abantu ukusiza ukuqinisekisa imininingwane enikezwayo, nge-ID eyingqayizivele yefayela, noma isignesha yedijithali ngokuhlangana nayo yonke imethadatha, ezothunyelwa ekhelini le-imeyili, i-SMS noma inethiwekhi yokuxhumana nabantu.
Amandla wohlelo lokusebenza ukuqinisekisa ubuqiniso besithombe ngasinye abalulekile kunoma ngubani. Yize sivuma ukuthi lolu lwazi olungeziwe lungabeka umsebenzisi engozini ngandlela thile, lolu lwazi olufanayo lunganikeza ubufakazi obubalulekile obukwaziyo ukwazisa okwenzekayo ngesikhathi nasendaweni.
Ungathola i-CameraV kufayela le- GooglePlay, I-F-droid noma ngokulanda ngqo kusuka kuseva I-Github.
Isicelo esithakazelisa kakhulu sokuzama sathiwa
Lo mbhalo ungaphezu kokudideka.
Okokuqala uthi uhlelo lususa imethadatha
bese kuba sobala ukuthi okwenziwa yilolu hlelo kuphambene:
iqoqa imethadatha eningi kufaka phakathi indawo yethu nge-GPS bese iyithumela efwini.
Ukubethelwa noma cha, anginandaba, okufanele kwenziwe abantu ukuhlanza yonke imibhalo yemethadatha ngaphambi kokuyifaka ku-inthanethi nokuthi kunezinhlelo ezithile ezifana ne-ExifTool
Umsebenzisi omuhle ekuseni, ngiyethemba ungaphinda ufunde le ndatshana ukuze ususe noma ikuphi ukudideka. Ngokuyinhloko, sikhuluma nge-ObscuraCam, i-App evela ku-TheGuardianProject esusa yonke imethadatha ezithombeni nakumavidiyo ngezizathu zokuphepha. Kepha-ke, uma ubheka imethadatha kusuka kwelinye iphuzu lokubuka, umbono wokuyisebenzisa njengomthombo wokuqinisekiswa kokuqukethwe uyavela, Futhi kuleli cala, iTheGuardianProject manje idala olunye uhlelo lokusebenza olubizwa ngeCameraV, olukhiqiza inani elikhulu lemethadatha ebethelwe ye- ukufakazela ubuqiniso bokuqukethwe.
Into ethokozisayo ngale ndaba ukuthi uhlelo lokusebenza olulodwa (i-ObscuraCam) luphathana lwenye (i-CameraV), futhi kuzoncika kuhlelo lokusebenza noma isidingo somsebenzisi sokusebenzisa eyodwa noma enye.
Iqiniso elithakazelisayo, ngiyabonga.
