Information protection specialists warn once again that the browser history is unique in each case, so it can identify each individual user.
Researchers from Mozilla, a company that develops the popular Firefox browser, claim in a report (PDF) that 99% of users can be identified using an Internet browser history.
The same is said by an independent cybersecurity expert:“The browser history is usually presented as a list of websites that the user has visited. For example, “google.com, facebook.com, reddit.com, bbc.co.uk, random-site.org, etcetc.org.uk”. “At first glance, such information may seem harmless, but it can be used to track a user and even create a digital image of him or her”.
Also, the expert noted that the history of visiting web pages practically does not change over time, which allows with a high degree of probability to “identify” a particular person without errors.
In terms of uniqueness and invariability, the expert compared the browser history with biometrics, which, in his opinion, provides the same level of identification.
In general, new research only confirms the conclusions of reports published in 2009-2011. The researchers decided to remind users and regulators once again that the history of site visits should be taken very seriously.
