Tshaj tawm hauv Chrome 89, kev sim ua haujlwm ntawm FLoC thev naus laus zis, tsim los ntawm Google los hloov cov ncuav qab zib uas taug qab kev txav, ntsib kev tawm tsam los ntawm zej zog. Tom qab siv FLoC, Google npaj yuav tsum tsis txhob txhawb nqa cov ncuav qab zib thib peb hauv Chrome / Chromium uas tau teeb tsa thaum nkag mus rau lwm qhov chaw uas tsis yog lub npe ntawm nplooj ntawv tam sim no. FLoC twb tau raug sim los ntawm ib feem me me ntawm Chrome 90 cov neeg siv, thiab kev txhawb nqa rau FLoC kuj suav nrog hauv Chromium codebase.
Raws li cov neeg tawm tsam ntawm kev siv FLoC, cov thev naus laus zis no, tsis txhob tso tseg tag nrho cov neeg siv taug qab, tsuas yog hloov ib hom phiaj nrog lwm tus, thiab, thaum sim daws qee qhov teeb meem, tsim lwm tus. Piv txwv li, FLoC tsim cov xwm txheej rau kev ntxub ntxaug rau cov neeg siv nyob ntawm lawv cov kev nyiam thiab kev xav.
Kev tshwm sim ntawm qee qhov haujlwm rau kev koom ua ke ntawm FLoC rau hauv Chromium codebase:
- Ib qho ntawm cov neeg tsim khoom tseem ceeb ntawm WordPress cov ntsiab lus tswj hwm, uas suav txog li 40% ntawm CMS kev ua lag luam, pom zoo kho FLoC raws li kev nyab xeeb kev nyab xeeb thiab ua kom zoo dua ntawm qhov tshwj xeeb lub peev xwm txwv tsis pub siv FLoC thiab lov tes taw kev tshawb nrhiav cov neeg siv khoom txaus siab. cov ntaub ntawv rau tus kheej qhov chaw. Kev xaiv tawm ntawm FLoC tuaj yeem qhib rau ntawm qhov chaw los ntawm kev teeb tsa HTTP header "Permissions-Policy: paj-cohort = ()". Nws tau thov kom muaj qhov zoo sib xws FLoC txwv txiav los ntawm lub neej ntawd hauv txhua qhov xwm txheej ntawm WordPress thiab hloov kho cov kev hloov pauv hauv ib qho kev hloov tshiab kom tshem tawm cov teeb meem kev nyab xeeb.
Yog tias qhov kev pom zoo tau pom zoo, txhua qhov chaw uas siv WordPress hloov tshiab yuav muaj FLoC ua haujlwm tsis zoo los ntawm lub neej ntawd. Rau cov neeg uas xav siv FLoC, ib qho kev xaiv yuav raug muab los kaw qhov kev sib kis ntawm "Permissions-Policy: paj-cohort = ()" header. Ib qho kev txwv zoo sib xws ntawm FLoC los ntawm lub neej ntawd kuj tau hais kom ntxiv rau qhov kev tso tawm loj ntawm WordPress 5.8, tab sis nws tau teem sijhawm rau Lub Xya Hli thiab tej zaum yuav tsis nyob rau lub sijhawm rau kev suav nrog FLoC, yog li muaj peev xwm ua tsis tau FLoC los ntawm kev hloov tshiab ib ntus. raug txiav txim siab.
Hauv cov lus pom, tsis yog txhua tus tau pom zoo nrog kev tawm tswv yim ntawm kev tso tawm qhov hloov tshiab no, sib cav tias kev txhawj xeeb txog kev nyab xeeb yuav tsum tsis txhob cuam tshuam nrog kev txhawj xeeb txog kev ceev ntiag tug. Kev tsim txom cov kev hloov pauv uas muaj nyob rau hauv qhov kev hloov kho tshiab tuaj yeem ua rau poob kev ntseeg siab hauv cov kev hloov tshiab.
- Cov neeg tsim tawm ntawm Vivaldi thiab Brave Browser browsers tsis kam siv FLoC kev txhawb nqa hauv lawv cov khoom, hais tias lawv cov neeg siv muaj cai ntiag tug. Vivaldi cov neeg sawv cev kuj tau taw qhia tias, hu rau spade spade, FLoC tsis yog kev siv thev naus laus zis, raws li Google tab tom sim txhawb nws, tab sis kev txwv tsis pub nkag mus txog kev siv thev naus laus zis.
- Lub koom haum tib neeg txoj cai EFF (Electronic Frontier Foundation) tau tshaj tawm lub vev xaib amifloced.org uas tso cai rau koj los txheeb xyuas qhov suav nrog FLoC hauv qhov browser, uas muab sijhawm rau cov neeg siv nkag siab tias nws puas koom nrog Google sim.
- Lub tshuab tshawb nrhiav DuckDuckGo thuam FLoC thiab ntxiv FLoC thaiv rau DuckDuckGo Privacy Essentials Chrome add-on, thiab tseem txwv tsis pub siv FLoC ntawm lub vev xaib duckduckgo.com (DuckDuckGo Search) los ntawm kev teeb tsa HTTP header "Permissions-Policy: paj-cohort =()".
- Microsoft tseem tsis tau pib ua kom FLoC hauv Edge browser, tau ua txoj hauv kev tos-thiab-saib thiab tab tom sim tsim nws tus kheej nyiam taug qab thev naus laus zis PARAKEET (Private and Anonymized Requests for Ads that Keep Efficacy and Enhance Transparency). Lub ntsiab lus ntawm PARAKEET yog kev siv lub npe neeg rau zaub mov nyob nruab nrab ntawm tus neeg siv thiab kev tshaj tawm xov xwm. Tus neeg siv tau muab tus cim tshwj xeeb, tab sis cov ntaub ntawv hais txog nws tsuas yog tau txais los ntawm tus neeg sawv cev, uas tsuas yog xa cov ntaub ntawv txwv tsis pub qhia tawm mus rau lub network tshaj tawm.
- Mozilla thiab Opera tsis muaj kev npaj ntxiv FLoC kev siv rau lawv cov khoom. Apple tseem tsis tau txiav txim siab zaum kawg txog kev siv FLoC hauv Safari.
- Lub uBlock ad blocker tam sim no disables FLoC thov los ntawm lub neej ntawd. Ib qho kev thaiv FLoC zoo sib xws tau ntxiv rau Adguard thiab Adblock Plus add-ons.
Cia peb nco qab tias FLoC (Federated Learning of Cohorts) API yog tsim los txiav txim siab qeb ntawm cov neeg siv khoom nyiam yam tsis muaj kev txheeb xyuas tus kheej thiab tsis siv rau keeb kwm ntawm kev mus xyuas cov chaw tshwj xeeb. FLoC tso cai rau koj txheeb xyuas cov pab pawg ntawm cov neeg siv uas muaj kev txaus siab zoo sib xws yam tsis tau txheeb xyuas tus neeg siv. Cov neeg siv kev txaus siab raug txheeb xyuas siv "cohorts," cov ntawv luv luv uas piav txog ntau pawg neeg nyiam. Cohorts yog xam nyob rau sab browser los ntawm kev siv tshuab kev kawm algorithms los saib cov ntaub ntawv keeb kwm thiab cov ntsiab lus uas tau qhib hauv browser. Cov ntsiab lus tseem nyob ntawm tus neeg siv sab, thiab tsuas yog cov ntaub ntawv dav dav hais txog pawg neeg raug xa mus rau sab nraud, cuam tshuam txog kev txaus siab thiab tso cai rau kev tshaj tawm cuam tshuam tsis tau taug qab tus neeg siv tshwj xeeb.
Cov kev pheej hmoo tseem ceeb cuam tshuam nrog kev siv FLoC:
- Kev ntxub ntxaug raws li cov neeg siv nyiam. Piv txwv li, txoj haujlwm thiab qiv nyiaj yuav txawv raws li haiv neeg, kev ntseeg, poj niam txiv neej thiab hnub nyoog. Cov neeg siv nyiaj ntsuab yuav raug tsom rau cov nyiaj qiv nrog cov paj laum, thiab tsom rau cov pej xeem thiab cov kev nyiam ntawm nom tswv yuav raug siv los ua cov ntaub ntawv tsis txaus ntseeg ntau dua. Nrog FLoC, cov ntaub ntawv coj tus cwj pwm yuav ua raws tus neeg siv los ntawm qhov chaw mus rau qhov chaw thiab cov ntaub ntawv ua haujlwm yav dhau los tuaj yeem siv los tswj tus neeg siv thaum qhib qhov chaw.
- Nws muaj peev xwm thim rov qab engineer koj cov keeb kwm kev tshawb nrhiav raws li cov ntaub ntawv sib koom ua ke. Kev tshuaj xyuas ntawm cov algorithm rau kev muab cov pab pawg yuav tso cai rau peb los txiav txim kwv yees li qhov chaw uas tus neeg siv yuav tuaj xyuas. Tsis tas li ntawd, raws li pawg neeg, ib tus tuaj yeem txiav txim siab txog hnub nyoog, kev coj noj coj ua, kev coj ua poj niam txiv neej, nyiam kev nom kev tswv, teeb meem nyiaj txiag lossis kev txom nyem.
- Qhov tshwm sim ntawm qhov tseem ceeb ntxiv rau qhov zais zais ntawm tus neeg siv tus browser ("browser fingerprinting"). Txawm hais tias FLoC pawg yuav npog ntau txhiab tus neeg, lawv tuaj yeem siv los txhim kho qhov tseeb ntawm kev txheeb xyuas qhov browser thaum siv ua ke nrog lwm cov ntaub ntawv tsis ncaj xws li kev tshuaj ntsuam xyuas, cov npe ntawm cov kev txhawb nqa MIME hom, tshwj xeeb tsis nyob hauv headers (HTTP / 2 thiab HTTPS ) , ntsia plugins thiab fonts, muaj qee qhov Web APIs, video card-specific rendering features using WebGL and Canvas, CSS manipulations, features of working with mouse and keyboard.
- Muab cov ntaub ntawv tus kheej ntxiv rau cov neeg taug qab uas twb txheeb xyuas cov neeg siv. Piv txwv li, yog tias tus neeg siv raug txheeb xyuas thiab nkag mus rau hauv nws tus as khauj, qhov kev pabcuam tuaj yeem cuam tshuam nrog cov ntaub ntawv nyiam tau teev tseg hauv pawg nrog rau tus neeg siv tshwj xeeb, thiab thaum pawg hloov pauv, taug qab qhov hloov pauv ntawm qhov nyiam.
Tsis tas li ntawd, nws tuaj yeem raug sau tseg tias nyob rau tib lub sijhawm, cov neeg sawv cev ntawm kev lag luam tshaj tawm tab tom tsim lwm txoj hauv kev txheeb xyuas tus kheej uas tuaj yeem siv los taug qab cov neeg siv yog tias cov ncuav qab zib thib peb raug thaiv hauv Chrome. Piv txwv li, Lub Tuam Txhab Trade Desk tau npaj UID2 (Unified Identifier) ββthev naus laus zis, uas siv cov txheej txheem kev txheeb xyuas tus neeg siv uas ua haujlwm nrog kev koom tes nrog cov tswv tsev. Tus cim UID2 yog tsim los ntawm cov ntaub ntawv muab los ntawm tus neeg siv thaum sau npe rau ntawm qhov chaw, xws li email, xov tooj, lossis cov ntaub ntawv social network. Raws li UID2 cov ntsiab lus encryption, tus neeg saib xyuas kev tsim kho vaj tse tsim lub token uas tus tswv tsev tuaj yeem hloov mus rau kev tshaj tawm xov xwm. Cov kev tso cai tshaj tawm tuaj yeem tau txais cov yuam sij los decrypt lub token thiab tau txais UID2 thawj, uas tuaj yeem siv los tsim kom muaj tag nrho cov neeg siv profile uas sib sau cov ntaub ntawv los ntawm ntau qhov chaw.
