What will new General Data Protection Regulation laws mean for websites that use sneaky web trackers such as browser fingerprinting<\/a>\u00a0to profile visitors? Privacy experts say the practice is likely illegal under the newly-enacted GDPR regulation. But they also say don\u2019t expect the method of tracking users to disappear anytime soon, said the Electronic Frontier Foundation in a\u00a0report issued Tuesday<\/a>.<\/p>\n

Using the HTML5 framework, websites are able to identify users (or a browser image) not by cookies, but the unique characteristics of a browser such as fonts, SVG widgets and WebGL\u2014for starters. The technique is called\u00a0browser fingerprinting or\u00a0canvas fingerprinting.\u00a0Websites harvest the browser data to produce a single, unique identifier to track users across multiple websites without any actual identifier persistence on the user\u2019s machine.<\/p>\n

While widespread regulations and laws \u2013 including the ePrivacy Directive and the recently enforced General Data Protection Regulation laws \u2013\u00a0 could address browser fingerprinting, websites participating in this practice \u201cwill try to skirt this law,\u201d Bill Budington, senior staff technologist at the EFF, told Threatpost.<\/p>\n

\u201cLooking at how web fingerprinting techniques have been used so far, it is very difficult to imagine companies moving from deliberate obscurity to full transparency and open communication with users,\u201d he said in a post<\/a>, written along with Katarzyna Szymielewicz, co-founder and president of the Panoptykon Foundation. \u201cFingerprinting companies will have to do what their predecessors in the cookie world did before now: face greater detection and exposure by coming clean about their practices, or slink even further behind the curtain, and hope to dodge European law.\u201d<\/p>\n

Browser fingerprinting is a handy tool for marketers. Browser fingerprinting can identify users over time, track them across websites, and store that information in their servers to build an advertising profile of them.<\/p>\n

That\u2019s separate from cookies, which can be deleted by the user.\u00a0Interestingly, browser fingerprinting can be used to recreate a tracking cookie for a user after the user knowingly become aware of the cookie and deleted it.<\/p>\n

The Impact of Existing Regulation<\/strong><\/p>\n

GDPR rules, which went into effect May 25<\/a>, have left privacy experts scratching their heads about what the data privacy protection crackdown means for methods such as browser fingerprinting.<\/p>\n

GDPR doesn\u2019t specifically call out fingerprinting \u2013 instead using \u201cneutral language\u201d that can quickly adapt to new emerging technologies or methods in the future,\u00a0 Budington said.<\/p>\n

\u201cFingerprinting can be used to identify users, and the individual characteristics of the browser can be identifiable via this method\u2026 That requires basic interactive consent of the user,\u201d said Budington. \u201cUnder GDPR, you would need a clear way to mark that you consent to the tracking.\u201d<\/p>\n

That path won\u2019t be easy for browser fingerprinters to get the green light by EU regulators, the EFF said in its post.<\/p>\n

Companies using browser fingerprinting would have to first reveal the fingerprinting\u00a0before\u00a0it is executed and secondly wait for users to give their informed consent. Sites that relied on fingerprinting would also need to lay out a \u201clegitimate interest argument for end users,\u201d meaning that it would need to prove that its interest in tracking is not overriding the rights of users to data privacy.<\/p>\n

The site would also need to share detailed information to users subjected to fingerprinting about the purpose and legal basis of such data processing, said Budington.<\/p>\n

On top of GDPR, another data privacy protection law exists called the ePrivacy Directive (aka \u201cthe cookie clause\u201d) which sets conditions on the use of device and browser identifiers.<\/p>\n

\u201cThis is something that is an additional standard above and beyond GDPR,\u201d Budington told Threatpost.\u00a0As it stands, one specific part of the ePrivacy Directive shows that device fingerprinting requires user consent:<\/p>\n

\n

\u201cParties who wish to process device fingerprints\u00a0which are generated through the gaining of access to, or the storing of, information on the user\u2019s terminal device must first obtain the valid consent of the user (unless an exemption applies).\u201d<\/p>\n<\/blockquote>\n

However, the EU is expected to pass an updated ePrivacy Regulation in 2019 that may hone in on browser fingerprints and offer more direct definitions of user data privacy consent.<\/p>\n

While GDPR and the ePrivacy Regulation both address browser fingerprinting,\u00a0 there\u2019s no evidence in practice that these rules would ultimately end sneaky browser practices like this method.<\/p>\n

However, many non-EU sites who track individuals in Europe using fingerprinting may ignore these laws under the belief that they can escape the consequences, Budington said.<\/p>\n

\u201cThere\u2019s nothing legitimate about this method of tracking: that\u2019s what privacy laws like the GDPR recognize, and that\u2019s what regulators will act upon,\u201d Budington said in the post. \u201cBefore we see results of their actions, browser companies, standards organizations, privacy advocates, and technologists will still need to work together to minimize how much third-parties can identify about individual users just from their browsers.\u201d<\/p>\n
