Momwe Mungachotsere Metadata pa Fayilo
Introduction
Metadata, yomwe nthawi zambiri imafotokozedwa kuti "za data," ndi mudziwe yomwe imapereka zambiri za fayilo inayake. Itha kupereka zidziwitso pamitundu yosiyanasiyana ya fayilo, monga tsiku lomwe idapangidwa, wolemba, malo, ndi zina zambiri. Ngakhale metadata imagwira ntchito zosiyanasiyana, imathanso kubweretsa ziwopsezo zachinsinsi komanso chitetezo, makamaka pogawana mafayilo omwe ali ndi zidziwitso zachinsinsi. M'nkhaniyi, tiwona kuti metadata ndi chiyani komanso momwe tingachotsere ku mafayilo kupita kuteteza zachinsinsi ndi chitetezo.
Kodi Metadata ndi chiyani?
Mukajambula chithunzi kapena kupanga chikalata, zambiri zimangoyikidwa mufayiloyo. Mwachitsanzo, chithunzi chojambulidwa ndi foni yam'manja chikhoza kukhala ndi metadata yovumbula chipangizo chomwe chagwiritsidwa ntchito, tsiku ndi nthawi yojambulira, ngakhalenso malo ngati GPS idayatsidwa. Mofananamo, zolemba ndi mafayilo ena zingaphatikizepo metadata yosonyeza mapulogalamu omwe amagwiritsidwa ntchito powapanga, dzina la wolemba, ndi mbiri yokonzanso.
Ngakhale metadata ikhoza kukhala yothandiza pakukonza ndi kuyang'anira mafayilo, imathanso kukhala pachiwopsezo pogawana zidziwitso zachinsinsi. Mwachitsanzo, kugawana chithunzi chokhala ndi data yamalo kumatha kusokoneza zinsinsi zanu, makamaka zikagawidwa pa intaneti. Chifukwa chake, ndikofunikira kuchotsa metadata m'mafayilo musanawagawane kuti mupewe kuwonekera mosakonzekera zachinsinsi.
Kuchotsa Metadata
Pamakina a Windows, mutha kugwiritsa ntchito zida ngati ExifTool kuchotsa metadata pamafayilo mosavuta. Mukakhazikitsa ExifTool GUI, ingotsitsani fayiloyo, sankhani metadata kuti muchotse, ndikuchotsani. Mukamaliza, fayiloyo idzakhala yopanda metadata iliyonse yophatikizidwa, kuonetsetsa zachinsinsi komanso chitetezo mukagawana.
Ogwiritsa ntchito a Linux amathanso kugwiritsa ntchito ExifTool kuchotsa metadata pamafayilo. Pogwiritsa ntchito terminal ndikuyika lamulo losavuta, ogwiritsa ntchito amatha kuvula mafayilo onse, ndikusiya mtundu woyera wokonzeka kugawana nawo. Njirayi ndiyolunjika komanso yothandiza, imapatsa ogwiritsa ntchito mtendere wamumtima akamagawana mafayilo omwe ali ndi chidziwitso chovuta.
Kutsiliza
Pomaliza, metadata imakhala ndi gawo lalikulu popereka nkhani ndi dongosolo kumafayilo koma imathanso kubweretsa ziwopsezo zachinsinsi ndi chitetezo zikagawidwa mosadziwa. Pomvetsetsa kuti metadata ndi chiyani komanso momwe mungachotsere mafayilo pogwiritsa ntchito zida monga ExifTool, ogwiritsa ntchito amatha kuteteza zinsinsi zawo ndi chitetezo chawo pogawana mafayilo pa intaneti. Kaya pa Windows kapena Linux, njira yochotsera metadata ndi yosavuta ndipo imawonetsetsa kuti zidziwitso zachinsinsi zimakhala zachinsinsi.
Kwa iwo omwe akufuna zida zowonjezera zachinsinsi ndi chitetezo, zosankha monga Gophish za phishing zoyerekeza ndi Shadowsocks ndi HailBytes VPN pazachinsinsi chokhazikika ndizofunika kuziwona. Kumbukirani kukhala tcheru ndikuyika zinsinsi patsogolo mukagawana mafayilo pa intaneti, ndipo nthawi zonse chotsani metadata kuti muchepetse zoopsa zomwe zingachitike.
