![]() Advertisers and AdTech vendors also use device fingerprinting to identify and track users across the Internet, which allows them to create user profiles and target them with personalized ads. Add that there is a pletora of consumer PCs with similar configurations. In a web analytics context, device fingerprinting is used to accurately identify and report on unique (i.e. Every human being has fingerprints, even before they are born, the fingerprints. Also, you would need a whole lot of samples to get statistically relevant results.ĮDIT: Browser fingerprint identifying power is weak: many browsers are autoupdating (like Chrome or Firefox) and official builts are very few (20? 40? Maybe a bit more if you count Linux distribution-compiled ones), so you will find a consistent portion of users with the same user agent. Fingerprints are unique patterns found on the tips of all fingers (and thumbs). It's a good proof concept, but nothing that you can use for this purpose. No way, you cannot set a variable or cookie from one domain and access it from another one in any decent browser, otherwise it would be a big security hole.ĮDIT: Panopticlick cannot be used as a tracking method as you suggested, because it is based on statistical matching and it is also pretty bad at that (try browsing from outside the USA or with the just-released Chrome/Firefox update). Whether or not fingerprints are unique to the individual (in a general sense) tells us nothing about how the identification process is carried out and whether or not it is done accurately and reliably. Also notice that user tracking is a delicate subject and you might incur into legal problems if you do not properly declare it in the TOS.ĮDIT: you cannot track a person across multiple web sites without using cookies in any of their variants (flash, session storage, etc.) and a domain shared between sites. ![]() ![]() Please bear in mind that the user can manipulate the HASHCODE and you should take that into account when engineering your application.Īnyway, notice that it's quite ugly in the fancy-url era. IdentoGO by IDEMIA provides a wide range of identity-related services with our primary service being the secure capture and transmission of electronic fingerprints for employment, certification, licensing and other verification purposes in professional and convenient locations. Whenever the server receives a request, it capture the HASHCODE if present, otherwise it generates one, and then append it to all links on the served page. Simplest way to keep a session without using cookies is appending a unique hash (maybe a UUID or something similar) to the urls in the page as a get parameter: /my/fancy/url ![]()
