Abaphandi be-Digital forensic banceda ukubamba kunye nokubeka kude izaphuli-mthetho ngokusebenzisa ubuchule obunjengokubuyisela idatha ukufumana ubungqina obubambekayo kwizixhobo zomrhanelwa. Ukukholelwa kuye kwaphunyezwa ngokujonga ii-imeyile, ukukhangela kwi-Intanethi, kunye neefayile ezicinyiweyo. Nantsi eminye imizekelo yendlela yokwenza ngayo ukufumana idatha iinkqubo zincede abomthetho ukuba bachonge abaphuli-mthetho.
I-Digital forensics luhlobo olutsha lwe-forensics olufumana ubungqina bezenzo zolwaphulo-mthetho kwi "artifacts zedijithali": iikhompyutha, ii-cloud drives, ii-hard drives, izixhobo eziphathwayo, kunye nokunye okunjalo.
Ubungqina obuninzi bokuba abaphandi be-digital forensic banokuqokelela ukuze baveze enkundleni buqokelelwa ngokusetyenziswa kweenkqubo zokubuyisela idatha. Umzekelo, iifayile ezicinyiweyo zinokufunyanwa kwakhona ngokusetyenziswa kweenkqubo ezifana DataNumen Data Recovery kunye neefayile ezikhuselweyo zephasiwedi zinokuvulwa ngeenkqubo ezifanayo ne DataNumen Outlook Password Recovery.
Iinkqubo zokubuyisela idatha ziqhele ukufumaneka kuluntu ngokubanzi kwaye ii-arhente zogcino-mthetho zinokusebenzisa ezi okanye iinkqubo ezintsonkothileyo ukuqokelela ubungqina bokubanjwa okanye isigunyaziso okanye ukufumana ukugwetywa. Oku kwaba njalo kwizaphuli-mthetho ezihlanu ezingezantsi.
1. UDennis Rader
UDennis Radar wayengumbulali we-serial owabulala abantu abalishumi ubuncinane eKansas ukusuka kwi-1974 ukuya kwi-1991. Wayeyaziwa ngokuba ngumbulali we-BTK ngenxa ye-MO yakhe. Wayedla ngokuqhekeza amakhaya amaxhoba akhe aze awabophe, awathuthumbise aze awabulale.
IRadar yayiza kuthumela iileta ezihlekisayo kunyanzeliso lomthetho nakumajelo eendaba kwaye oku kwaba yiyo ekugqibeleni eyanceda ukubanjwa kwakhe. I-Radar yayithumele i-floppy disk kwisikhululo sikamabonwakude kwaye izazinzulu zedijithali zenzululwazi zakwazi ukubuyisela uxwebhu olucinyiweyo lwe-Microsoft Word kuyo olukhokelele ukuba bachonge iRader.
2. UJoseph E. Duncan III
UJoseph Edward Duncan III ungumxhaphazi wabantwana kunye nombulali we-serial okwangoku ekuluhlu lokufa ngenxa yokuxhwilwa kunye nokubulawa kosapho e-Idaho kunye nokubulawa kwenkwenkwe eCalifornia.
Xa abaphandi bedijithali behlola ikhompyuter yakhe, bakwazile ukufumana i-spreadsheet apho wayecwangcise khona ubugwenxa bakhe. Oku kwasetyenziswa njengobungqina bokuba izenzo zakhe zazicwangciswe kwangaphambili kwaye yayisesinye sezizathu zokuba anikwe isigwebo sokufa.
3. URobert Frederick Glass
URobert Frederick Glass wagwetywa okanye wathuthumbisa waza wakrwitsha wafa uSharon Rina Lopatka eMaryland.
Amapolisa axwayiswa ngokubandakanyeka kweGlass ekubulaweni kukaLopatka emva kweeveki ezintandathu zeengxoxo ze-imeyile zafunyanwa phakathi kwezi zibini ezikhokelela ekufeni kwakhe. Aba babini baye badibana kunye ne-tryst yokuzalisekisa iingcamango zesondo zokuhlushwa uLopatka.
Eli tyala, ngo-1996, lelinye lamatyala okuqala amkelweyo amapolisa achonga umrhanelwa wokubulala ngenxa yobungqina obufunyenwe kwii-imeyile.
4. UGqr Conrad Murray
UGqr. Murray wayengugqirha wemvumi yepop uMichael Jackson. UJackson wabulawa kukusetyenziswa kakubi kweyeza lokuthomalalisa elibizwa ngokuba yipropofol.
UGqr. Murray wamangalelwa nge-involuntary ukubulawa kwabantu ngenxa yokufa kukaJackson. Ukugwetyelwa kwakhe ngokuyinxenye ngenxa yobungqina obafunyanwa kule khompyutha obubonisa ukuba wayesoloko echaza ngakumbi ipropofol kuJackson.
5. Krener Lusha
Ngo-2009, e-United Kingdom, uKrener Lusha wabanjwa ngokurhanelwa ukuba uceba ukwenza izenzo zobugrogrisi. Abomthetho baqhubele phambili ukuba babambe uLusha ngokusekelwe kubungqina bedijithali.
Ngexesha lokubanjwa kwakhe kwabanjwa ilaptop kaLusha kwaye i-digital forensics ubhaqe imbali yakhe yokukhangela, equka ukukhangelwa kwendlela yokwenza iibhombu kunye neevesti zokuzibulala. Izinto ezihambelanayo ezacetyiswa kuphando lwakhe nazo zafunyanwa kwigumbi lakhe.
Imibhalo yeengxoxo ezifunyenweyo apho uLusha wazibonakalisa “njengomnqolobi” owayefuna ukubona “amaYuda namaMelika ebulawa” yafunyanwa kwilaptop yakhe yasiwa enkundleni.
