Waxaan wax ka qori jirnay Qarsoonnimada onlaynka^{(Online Privacy)} ah iyo agabka daboolaya ee sheeganaya wadarta sirnimada: Proxies, VPNs iyo software la mid ah. Laakiin ma aanan ka fikirin arrintan, in website-yada ay hore u yaqaaneen qofka aad tahay! Habkan waxa loo yaqaan Farta Aaladda^{(Device Fingerprinting)} ama Farta Browser^{(Browser Fingerprinting)} . In this post, waxaan ka hadli doonaa waxa ay tahay Browser Fingerprint ka dibna fiirin doonaa haddii aan wax habab ah oo aan uga fogaanno habka lagu baafinayo ama adiga.

Farta browserka

Ururinta xogtaada mareegaha aad booqato adigoo isticmaalaya browser kasta oo ku aqoonsanaya xogtaas waa Bowser Fingerprinting . Ku dhawaad^(Almost) ​​isticmaale kasta oo internet- ku wuxuu leeyahay habayn kala duwan oo browser-kiisa ama keeda. Ma aha oo kaliya macluumaadka browserka, laakiin sidoo kale waxaa suurtogal ah in mareegaha ay ku shaqeeyaan JavaScript ama script Flash si ay u ogaadaan nooca shaashadda kumbuyuutarka ee aad leedahay, fonts on the system, Cookies iyo wixii la mid ah.

Laakiin haddii aad isticmaalayso wakiil iyo VPN^(Proxy) , waxyaalahan miyay muhiim yihiin ? ^(VPN)Wakiilku waxa uu bedelayaa^{(Proxy )} goobtaada. Kuma darto mana ka saarto kordhinta biraawsarkaaga mana bedesho habaynteeda. Sidoo kale^(Likewise) , VPN sidoo kale ma beddeli doonto xallinta shaashaddaada iyo qoto dheeraanta pixel. Midkoodna kama joojin karo mareegaha inuu weydiiyo farfaha lagu rakibay kombiyuutarkaaga ama ma qarin karaan isku xigxiga si ay ugu ekaadaan kumbuyuutar kale.

Si kale haddii loo dhigo, ma beddeli karaan ama ma tirtiri karaan Raad- raacyada Browserkaaga^{(Browser Footprints)} . In kasta oo ay jiraan doorashooyin hadda, browser-yada intooda badan si ay u weydiiyaan mareegaha in aanay ku dabagalin, mareegaha(yada) waxa laga yaabaa ama ma aqbali karaan codsiga. Waxa kale oo aad isticmaali kartaa qaar ka mid ah qalabka dhinac saddexaad si ay kaaga caawiyaan dhimista, daba-galka iyo raadinta. Way shaqeeyaan, laakiin ma xannibi karaan weydiimaha ka imanaya mareegaha.

U soo noqoshada waxa ay tahay Browser Fingerprinting , waxaa jira shirkado dhinac saddexaad ah oo qaata hawsha lagu aqoonsanayo adiga oo ka mid ah malaayiin kale oo booqanaya goob gaar ah. Inta badan xogta waxaa lagu helaa iyadoo la waydiiyo biraawsarkaaga: Tirada kordhinta, kordhinta la rakibay, goobaha browserka, cookies-ka aad ogolaatay inaad ku kaydiso kumbuyuutarkaaga iyo xogta la mid ah. Shirkadaha qaarkood waxay ku daraan qoraal si ay u ogaadaan habaynta nidaamkaaga. In short, they first identify you and then track you, usually for profit!

Hadda oo aad ogtahay in shabakadaha internetka ay ku aqoonsan karaan adiga oo isticmaalaya habab kala duwan, waxaa laga yaabaa inaad rabto inaad ogaato sida looga baxsado tuuganimada noocan ah.

Haddi aad u janjeerto, waxa aad tijaabin kartaa kala duwanaanshaha biraawsarkaaga adiga oo booqanaya xidhiidhkan Panopticlick^{(this Panopticlick link)(this Panopticlick link)} . Goobtani waxay kuu sheegaysaa sida ay u fududahay ama u adag tahay in la ogaado faraha browserka.

Ka fogow, dami faraha browserka

In kasta oo ay jiraan plugins qaar ka mid ah Chrome iyo Firefox kuwaas oo sheeganaya in ay qabtaan hawsha iyaga oo si aan kala sooc lahayn awood u siinaya oo curyaaminaya add-ons, uma malaynayo in tani runtii shaqayn karto. Waxay sii sheegi doontaa shabakadaha wax ku saabsan biraawsarkaaga adoo isticmaalaya plugins-yadan gaarka ah. Intaa waxaa dheer, waxay awood u siinayaan ama curyaamiyaan plugins kale, sidaas darteed shabakadaha mar walba waxay akhrin karaan waxa dhammaan plugins iyo kordhinta ay joogaan xitaa haddii ay naafo yihiin.

Waxaad gacanta ku dari kartaa plugins ka hor inta aanad bilaabin kulanka daalacashada Mar kasta, waxaad ka saari kartaa iyaga oo aad ku dari kartaa plugins kale. Tani sidoo kale jawaab adag uma aha ka hortagga ama curyaaminta faraha browserka.

Dhibka ugu weyni waa in ay ku weydiin karaan kombiyuutarkaaga iyaga oo isticmaalaya Javascript ama Flash code^{(Javascript or Flash code)} . Koodhka Flash wuxuu^(Flash) ku siin karaa macluumaad wanaagsan oo ku saabsan nidaamkaaga.

Ma hubo, laakiin waxaan filayaa in aan meel akhriyay oo aad ka joojin karto su'aalaha nidaamka adiga oo ka joojinaya Flash-ka kombiyuutarkaaga, maadaama ay website-yadu isticmaalaan qoraalka Flash si ay u waydiiyaan kombiyuutarkaaga. Haddii mid idinka mid ah uu xogtan ka hayo, fadlan la wadaag.^{(I am not sure, but I think I read somewhere that you can disable system querying by disabling Flash on your computer, as the websites use Flash scripting to query your computer. If any of you have information on this, please share.)}

Qaar ayaa laga yaabaa inay u maleynayaan in isticmaalka InCognito ama qaabka InPrivate^{(InPrivate mode)} ay ku caawin karto. Laakin iyada oo aan la kordhin, waxay wali siisay aqoonsi u gaar ah biraawsarkaaga, " Hey, kani waa ninka had iyo jeer adeegsada qaabka InCognito… laakiin waan akhriyi karaa kordhinta uu ku leeyahay biraawsarkiisa… sug, sidoo kale waxaan arki karaa jaangooyooyinkiisa browserka^{(Hey, this is the guy who always uses InCognito mode… but I can read the extensions he has on his browser… wait, I can also see his browser settings)} " .

Akhriso^(Read) : Waa maxay Dabagalka Shabkada? Waa maxay Trackers in browsers?^{(What is Web Tracking? What are Trackers in browsers?)}

Waxaa ka mid ah dhowr tillaabo oo aad qaadi karto si aad uga hortagto ama u joojiso faraha browserka, waxaad sidoo kale isku dayi kartaa kuwan:

1. Dami JavaScript^{(Disable JavaScript)} . Deminta JavaScript waa difaac adag oo ka dhan ah faraha browserka sababtoo ah waxay jaraysaa koodka ay shabakadaha internetka isticmaalaan si ay u ogaadaan plugins, fonts, isticmaalka supercookies, iwm. Laakiin tani waxay saameyn kartaa khibradahaaga wax raadinta.
2. Isticmaal TorButton _ Waxay jaangooyaa inta badan sifooyinka browserka iyo xadhkaha waxayna sidoo kale xannibi kartaa JavaScript gudaha browserka. Plugins ayaa sidoo kale diyaar u ah daalacashada.
3. Fiiri sida loo  xannibo Canvas Fingerprint ee Chrome^{(block Canvas Fingerprinting in Chrome)} iyo Firefox .
4. Mareegta CoverYourTracks^{(CoverYourTracks)} ayaa ku tusinaysa sida raad-raacayaashu u arkaan biraawsarkaaga, iyagoo ku siinaya dulmar ku saabsan sifooyinkaaga gaarka ah iyo kuwa lagu garto.

Tani waa waxa aan ka soo ururin karo faraha browserka. Akhbaarta kaliya ee wanaagsan ayaa ah in goobo badan aysan isticmaalin farsamadan - weli!

Haddii aad u malaynayso in aan wax seegay ama haddii aad rabto inaad wax ku darto, fadlan nala wadaag adigoo isticmaalaya sanduuqyada faallooyinka.^{(If you think I missed something or if you wish to add something, please share it with us using the comment boxes.)}

Browser Fingerprinting. How to disable Browser Fingerprints

We have been writing about Online Privacy and covering tools that claim total privacy: Proxies, VPNs and similar software. But we did not think about this, that websites already know who you are! The method is known as Device Fingerprinting or Browser Fingerprinting. In this post, we’ll talk about what is Browser Fingerprint and then see if we have any methods to avoid the method of tracking or tracing you.

Browser Fingerprinting

A collection of your data by websites you visit using any browser and identifying you based on that data is Bowser Fingerprinting. Almost every user of the Internet has different settings for his or her browser. Not only browser information, but it is also possible for websites to run a JavaScript or Flash script to know the type of the computer screen you own, fonts on the system, Cookies and so on.

But if you are using a Proxy and a VPN, do these things matter? A Proxy just changes your location. It does not add or remove extensions from your browser or change its settings. Likewise, a VPN too will not change your screen resolution and pixel depth. None of them can stop the website from querying the fonts installed on your computer or hide their sequence to make it look like a different computer.

In other words, they cannot modify or erase your Browser Footprints. Though there are options now, in most browsers to ask websites to Not Track you, the website(s) may or may not accept the request. You can also use some third-party tools to help in reducing, tracking and tracing you. They do work, but they cannot block queries coming from the websites.

Read: How to protect Personally Identifiable Information on the Internet.

Coming back to what is Browser Fingerprinting, there are third-party companies that take up the task of identifying you among millions of others visiting a particular site. Most of the data is obtained by querying your browser: The number of extensions, the installed extensions, browser settings, cookies you permitted to store on your computer and data like that. Some of the companies add a script to know your system configuration. In short, they first identify you and then track you, usually for profit!

Now that you know that websites can identify you using different methods, you might want to know how to escape this kind of snooping.

If you are inclined to, you can test your browser’s uniqueness by visiting this Panopticlick link. This site tells you how easy or tough would it be to figure out the browser fingerprints.

Avoid, disable Browser Fingerprints

Though there are some plugins for Chrome and Firefox that claim to do the task by randomly enabling and disabling add-ons, I do not think this can really work. It would further tell the websites about your browser using these specific plugins. Plus, they only enable or disable the other plugins, so the websites can always read what all plugins and extensions are present even if they are disabled.

You can manually add some plugins before starting the browsing session. And each time, you may remove them and add some other plugins. This too is not a solid answer to preventing or disabling browser fingerprints.

The main problem is that they can query your computer using Javascript or Flash code. A Flash code can give away good information about your system.

I am not sure, but I think I read somewhere that you can disable system querying by disabling Flash on your computer, as the websites use Flash scripting to query your computer. If any of you have information on this, please share.

Some might think that using InCognito or InPrivate mode might help. But without extensions, it is still giving a unique identity to your browser, “Hey, this is the guy who always uses InCognito mode… but I can read the extensions he has on his browser… wait, I can also see his browser settings“.

Read: What is Web Tracking? What are Trackers in browsers?

Among the several steps you could take to prevent or disable browser fingerprinting you could try these too:

1. Disable JavaScript. Disabling JavaScript is a powerful defense against browser fingerprinting because it cuts off the code that websites use to detect plugins, fonts, use of supercookies, etc. But this could affect your browsing experiences.
2. Use TorButton. It standardizes most browser characteristics and strings and can block JavaScript in the browser too. Plugins are available for browsers too.
3. See how to block Canvas Fingerprinting in Chrome and Firefox.
4. CoverYourTracks website shows you how trackers see your browser, providing you with an overview of your most unique and identifying characteristics.

This is what I could gather about browser fingerprinting. The only good news is that not many sites employ this technique – yet!
