Key Takeaways
- Ib txoj kev nrhiav pom tshiab uas siv lub computer GPU ua rau muaj kev txhawj xeeb txog kev ceev ntiag tug.
- Txoj kev tshiab tsis tas yuav nkag mus rau cov khoom siv ntxiv xws li lub microphone, lub koob yees duab, lossis gyroscope.

Cov kws tshaj lij ntiag tug hais tias muaj txoj hauv kev los tiv thaiv koj tus kheej siv cov web browsers ruaj ntseg dua.
Nws yuav yog lub sijhawm txhawj xeeb ntau dua li cov lej tsis zoo ntawm koj lub cuab yeej.
Cov kws tshawb fawb tau nthuav tawm txoj hauv kev tshiab los taug qab koj thoob plaws hauv Is Taws Nem siv koj lub khoos phis tawj lossis xov tooj lub chaw ua haujlwm duab (GPU). Nws yog ib feem ntawm kev txhawj xeeb loj zuj zus ntawm cov kws tshaj lij kev nyab xeeb txog txoj hauv kev ntawm cov neeg siv cov ntaub ntawv tawm mus uas tuaj yeem cuam tshuam txog kev ceev ntiag tug.
"Raws li nws tsis muaj tseeb rau tus neeg siv los qhib lawv lub kaw lus thiab hloov lawv GPU txhua zaus lawv mus online, txoj hauv kev tshiab no rau kev taug qab cov tib neeg tuaj yeem ua pov thawj qhov teeb meem tseem ceeb rau kev kov yeej rau cov neeg tawm tswv yim ntiag tug thiab yuav xav tau kev cai lij choj, xws li cov kev cai tshiab, los tiv thaiv kev ceev ntiag tug ntawm cov neeg siv uas xav tsis qhia npe online, "Frank Downs, tus thawj coj loj ntawm cov kev pabcuam cuam tshuam ntawm cybersecurity tuam txhab BlueVoyant, hais rau Lifewire hauv kev xam phaj email.
Txhob Cia Siab Rau Tus Kheej
Lub tsev ua cov duab yog ib lub voj voog hauv cov khoos phis tawj thiab cov xov tooj smartphones tsim los tsim cov duab, thiab nws yog qhov muaj peev xwm ntawm kev txhawj xeeb txog kev ceev ntiag tug.
Ib pawg neeg tshawb fawb thoob ntiaj teb tau sau rau hauv daim ntawv tshiab tias lawv tau pom lub tswv yim ntiv tes uas siv cov khoom ntawm txhua tus neeg siv GPU pawg los tsim cov ntaub ntawv taug qab.
Browser fingerprinting yog ib txoj hauv kev los taug qab tib neeg thoob plaws hauv internet, tab sis nws tsis kav ntev. Ntawm qhov tod tes, GPU ntiv tes tso cai rau cov kws tshawb fawb los tsim "kev txhawb nqa txog li 67% rau lub sijhawm nruab nrab ntawm kev taug qab," raws li daim ntawv.
"Yav dhau los, ib txwm muaj txoj hauv kev taug qab cov neeg siv khoom hauv online, xws li ncuav qab zib, muab cov ntaub ntawv nthuav dav rau cov koom haum taug qab," Downs hais. "Txawm li cas los xij, raws li cov neeg siv khoom tau dhau los ua neeg txawj ntse thiab pib thaiv qee txoj hauv kev no, cov tuam txhab tau nce lub hom phiaj kos npe uas yog kho vajtse thiab nyuaj rau cov neeg siv hloov pauv, xws li roj teeb qib thiab tam sim no, muaj peev xwm, cov ntaub ntawv GPU."
Cov txheej txheem tshiab ua haujlwm zoo ob qho tib si ntawm PCs thiab cov khoom siv txawb. Nws "muaj qhov ua tau zoo offline thiab online runtime thiab tsis tas yuav nkag mus rau ib qho ntxiv sensors xws li lub microphone, lub koob yees duab, lossis gyroscope," cov kws sau ntawv sau rau hauv daim ntawv.
Kev tshawb fawb tuaj yeem tsim teeb meem rau cov neeg siv, Danka Delic, tus kws sau ntawv ntawm ProPrivacy, tau hais hauv kev xam phaj email. Lub sijhawm koj mus ntsib txhua lub vev xaib uas txhawb nqa WebGL (a JavaScript API rau kev sib tham sib tham 2D thiab 3D duab), koj tuaj yeem dhau los ua lub hom phiaj rau kev taug qab, nws ntxiv. Yuav luag txhua lub vev xaib loj txhawb nws.
"Tsis hais, tiam tom ntej GPU APIs tab tom txhim kho raws li peb hais, uas tuaj yeem muaj ntau txoj hauv kev rau cov neeg siv internet ntiv tes, tej zaum yuav nrawm dua thiab raug dua, ib yam nkaus," Delic hais.
Tsis txhob ntshai, Tseem
Qee tus kws tshaj lij hais tias kev taug qab GPU tseem tsis tau muaj kev hem thawj rau cov neeg siv nruab nrab.
"Nco ntsoov tias, raws li tsab xov xwm tshawb fawb tau hais, browser "ntiv tes" yog ntau yam kev kos duab raws li kev tshawb fawb-thiab nyob deb ntawm 100% ua tau zoo," Allen Gwinn, tus xibfwb hauv Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab Kev Ua Haujlwm Kev tswj hwm ntawm Cox Tsev Kawm Ntawv ntawm Kev Lag Luam, Southern Methodist University, hais rau Lifewire ntawm email.
Qhov teeb meem GPU tsuas yog ib qho ntxiv "kev xaiv" rau cov neeg sim taug qab koj, Gwinn tau hais. Muaj ntau lwm yam kev tso cai ntxiv (Facebook, Twitter, Amazon, thiab lwm yam thiab lawv cov ncuav qab zib) uas tib neeg ua los muab cov ntaub ntawv taug qab uas thaum kawg cua tuaj rau ntawm ob sab tes, nws hais ntxiv.
"Tam sim no qhov teeb meem GPU tau paub, cov xwm txheej xav tau yuav tshwm sim: Firefox, Siab tawv, TORbrowser, thiab lwm yam, yuav txo qis," Gwinn hais. "Chrome (Google), Edge (MS), tej zaum yuav tsis ua dab tsi. Cov plugins thib peb kuj tseem yuav ua rau qhov teeb meem no thiab muab kev tiv thaiv."
Txhawm rau tiv thaiv nws tus kheej los ntawm qhov teeb meem GPU, Gwinn siv DuckDuckGo ua lub tshuab tshawb nrhiav thawj zaug thiab tsuas yog tshawb Google ua tus thaub qab. Nws siv Firefox thiab Brave ua nws thawj browser, nrog rau Facebook Container plugin rau kev ruaj ntseg. Nws kuj tau tshem tawm Facebook app los ntawm nws lub xov tooj ntawm tes thiab tsuas yog nkag mus rau nws los ntawm qhov browser nrog kev tso cai feem ntau tsis pom zoo.
"Cov no yog cov kev paub zoo uas tuaj yeem txo koj cov hneev taw hauv internet," Gwinn hais. "Kuv hais rau kuv cov menyuam kawm ntawv kom tshem tawm (thiab tshem tawm cov apps ntawm) tag nrho cov kev tshaj tawm txog yim lub hlis ua ntej koj mus yos hav zoov. Ntxiv rau, ceev faj qhov koj tshaj tawm vim tias cov duab "ntxim hlub" me me ntawm koj ntawm lub puam ntawm Caij Nplooj Hlav nrog ib tug npias tuaj yeem raug cais tsis raug los ntawm lub tuam txhab kev sib raug zoo ntawm cov khoom siv dag zog-thiab thaum kawg xaus rau hauv tes ntawm lub tuam txhab kev tua neeg."
