Well for one thing, an IP address is always going to be the easiest way to track a user, but also user agent information which browsers happily give away too much information.
- selcuka 5y ago> an IP address is always going to be the easiest way to track a user Note that an IP address is not unique to a single user (NAT, CGNAT, mobile networks) and may frequently change. > also user agent information All users who use the same version of a browser on the same OS typically share the same user agent string (unless modified with a plugin or an extension). It's an indicator, but can't be used as a fingerprint itself.
- czbond 5y agoYes, for many. VPN's, mobile connections, and commercial work connections (using a proxy) will throw off IP address checks as they report a single IP for large pool groups. You'd have to also use MAC address, but mobile have MAC address swapping ,etc. I once wrote a tool that would capture all network requesters, and reverse fingerprint them through a connection of Operating system quirks responses to network oddities (eg: tcp fragmented frames), location, routers they connect through, etc combined with the other browser things avail.
- jefftk 5y ago> IP address is always going to be the easiest way to track a user This is changing: Apple has rolled out Private Relay, and Chrome is planning some combination of willful IP blindness and near-path NAT. > user agent information which browsers happily give away too much information So is this: all the browsers are working on reducing how much they put in the UA.
