--- type: Article title: "FP-STALKER: Tracking Browser Fingerprint Evolutions" description: FP-STALKER links successive browser fingerprints from the same browser as they drift, using a rule-based matcher and a random-forest hybrid to decide whether two fingerprints share an origin. Over 98,598 fingerprints from 1,905 browsers it follows a browser for 54 days on average and a quarter of them past 100 days, so fingerprint churn does not defeat stateless tracking. resource: "https://hal.inria.fr/hal-01652021" tags: [article, webseclist-reference, en, hal-inria-fr, info-leak, javascript, measurement-study, large-scale-scan] generated: by: webseclist-refs/1 at: "2026-08-09T05:14:36+00:00" status: stable stale_after: 2027-08-09 sources: - id: original resource: "https://hal.inria.fr/hal-01652021" title: "FP-STALKER: Tracking Browser Fingerprint Evolutions" author: Antoine Vastel, Pierre Laperdrix, Walter Rudametkin, Romain Rouvoy - id: capture resource: "https://web.archive.org/web/20191014054524/https://hal.inria.fr/hal-01652021" also_at: [] authors: - Antoine Vastel - Pierre Laperdrix - Walter Rudametkin - Romain Rouvoy canonical_url: "" cited_by: - "2016-17.md:106" commit: "" content_sha256: 6a17bca20c3e1b89f54957feb911f9204876f6c469de7c4b3d109ce70dec4105 depth: full depth_reason: default kind: article language: en licence: unknown original_url: "https://hal.inria.fr/hal-01652021" published: "" publisher: hal.inria.fr publisher_english: "" raw_sha256: f69d787ad079790a0990486d3c9aa54f900ec5eda7d84ec13e3141098659ec93 retrieved_from: "https://hal.inria.fr/hal-01652021" retrieved_kind: stored retrieved_utc: "2026-08-09T05:14:36+00:00" slug: hal-inria-fr-fp-stalker-tracking-browser-fingerprint-evolutions snapshot: 20191014054524 title_english: "" translation_file: "" translation_of: "" --- # FP-STALKER: Tracking Browser Fingerprint Evolutions **FP-STALKER: Tracking Browser Fingerprint Evolutions** - Antoine Vastel, Pierre Laperdrix, Walter Rudametkin, Romain Rouvoy, hal.inria.fr. - Published: date not stated - Original: - Preserved from: https://hal.inria.fr/hal-01652021 (stored) on 2026-08-09 - Capture timestamp: 20191014054524 - Licence: unknown Rights remain with the original author and publisher.

Unlike cookies, fingerprinting is a stateless technique that does not store any information on devices, but instead exploits unique combinations of attributes handed over freely by browsers. The uniqueness of fingerprints allows them to be used for identification. However, browser fingerprints change over time and the effectiveness of tracking users over longer durations has not been properly addressed. In this paper, we show that browser fingerprints tend to change frequently—from every few hours to days—due to, for example, software updates or configuration changes. Yet, despite these frequent changes, we show that browser fingerprints can still be linked, thus enabling long-term tracking. FP-STALKER is an approach to link browser fingerprint evolutions. It compares fingerprints to determine if they originate from the same browser. We created two variants of FP-STALKER, a rule-based variant that is faster, and a hybrid variant that exploits machine learning to boost accuracy. To evaluate FP-STALKER, we conduct an empirical study using 98,598 fingerprints we collected from 1,905 distinct browser instances. We compare our algorithm with the state of the art and show that, on average, we can track browsers for 54.48 days, and 26 % of browsers can be tracked for more than 100 days. **Keywords** : [browser fingerprinting](https://hal.inria.fr/search/index/q/*/keyword_t/browser fingerprinting/) [random forests](https://hal.inria.fr/search/index/q/*/keyword_t/random forests/) [user tracking](https://hal.inria.fr/search/index/q/*/keyword_t/user tracking/) **Document type** : Conference papers **Domain** : > ** [Computer Science [cs]](https://hal.inria.fr/search/index/q/*/level0_domain_s/info) / [Web](https://hal.inria.fr/search/index/q/*/level1_domain_s/info.info-wb) ** [Computer Science [cs]](https://hal.inria.fr/search/index/q/*/level0_domain_s/info) / [Software Engineering [cs.SE]](https://hal.inria.fr/search/index/q/*/level1_domain_s/info.info-se) [Computer Science [cs]](https://hal.inria.fr/search/index/q/*/level0_domain_s/info) / [Cryptography and Security [cs.CR]](https://hal.inria.fr/search/index/q/*/level1_domain_s/info.info-cr) [Computer Science [cs]](https://hal.inria.fr/search/index/q/*/level0_domain_s/info) / [Machine Learning [cs.LG]](https://hal.inria.fr/search/index/q/*/level1_domain_s/info.info-lg) Complete list of metadatas ** Display Cited literature [23 references] ** Display ** Hide [ ** Download ](https://hal.inria.fr/hal-01652021v1/html_references) --- https://hal.inria.fr/hal-01652021 Contributor : [Romain Rouvoy](https://hal.inria.fr/search/index/q/*/contributorId_i/102479/) < > Submitted on : Saturday, December 2, 2017 - 3:39:47 PM Last modification on : Friday, September 13, 2019 - 9:48:41 AM
