Google is running a Chrome "origin trial" to test out an experimental new tracking feature called Federated Learning of Cohorts (aka "FLoC").FLoC exists because Google acknowledges the privacy harms of third-party cookies, but insists on continuing to let advertisers target you based on how you browse the web.

They tested five cache analysis methods on four processor architectures (Intel Core, AMD Ryzen, Apple M1, Samsung Exynos).The result: all these platforms are vulnerable to varying degrees.

Researchers from the University of Illinois, Chicago said in a new paper that most browsers cache the images in a location that’s separate from the ones used to store site data, browsing history, and cookies.

Some users will argue that Google could take more drastic measures and simply use its tech prowess to stop the ad ecosystem from tracking you through cookies, fingerprinting and whatever else the adtech boffins will dream up next.

So today, we are announcing a new initiative to develop a set of open standards to fundamentally enhance privacy on the web.Starting with today’s announcements, we will work with the web community to develop new standards that advance privacy, while continuing to support free access to content.

Boffins from Graz University of Technology in Austria have devised an automated system for browser profiling using two new side channel attacks that can help expose information about software and hardware to fingerprint browsers and improve the effectiveness of exploits.

When Queensland sawmill worker Jeremy Lee refused to give his fingerprints to his employer as part of a new work sign-in, he wasn't just thinking about his privacy.

Because relatively few people change their VPN server location during 1 session, trackers can be pretty sure that two users with exactly same browser fingerprint and TCP/IP fingerprint but different IP address, one.

Given the rise in harmful practices like cryptocurrency mining and fingerprinting, Mozilla has now introduced a new anti-tracking feature for its Firefox browser. Once you are on the latest Nightly Beta 68 or Beta 67 version of Firefox , the anti-tracking feature will have to be enabled manually.

We have added a feature to block fingerprinting and cryptomining in Firefox Nightly as an option for users to turn on. In Firefox Nightly 68 and Beta 67, these new protections against fingerprinting and cryptomining are currently disabled by default.

This article is a short guide to using JA3 for fingerprinting TLS clients, with possible use cases and a simple demo. At the implementation level this can translate to: advertising dummy future ciphers each time in order to create unique fingerprints.

"From the negative perspective, people can use our cross-browser tracking to violate users' privacy by providing customized ads," Yinzhi Cao, the lead researcher who is an assistant professor in the Computer Science and Engineering Department at Lehigh University, told Ars.

In the case of tracking and fraud detection, the goal is to obtain a canvas as unique and stable as possible in order to distinguish the maximum number of users. Diversity of canvas fingerprints In total we encountered 69 different canvas present on 3,825 distinct websites.

Using the two methods, companies that utilize web trackers can collect massive amount of data from which they can create detailed user profiles, and use them for marketing purposes. Other strategies companies can use to track users, include: using web beacons, server logs, browser user-agent and Flash cookies.
