Ways another user can look like you
From Digital Economy Act Info
One of the differences between the act and existing copyright law is there is no requirement to prove an individual is infringing copyright, only than an internet subscriber's connection is. This leads to the problem that subscribers' details can be incorrectly identified, either because of technological limitations, or because they are forged.
It's important you learn about how this might happen, so you can try to protect your network connection.
Shared / Public Access
Unauthorized Wifi Access
If your broadband connection also provides you with a wifi connection, then this is another manner in which your connection can be used without your knowledge. The technology used to secure your wifi connection is unfortunately vulnerable. You may have noticed security terms like 'WEP' or 'WPA2' when you connect - these are affected. WEP for example has been very much broken and the variants of WPA and WPA2 that are available on your home routers have vulnerabilities too. What this means to you, is that no matter which settings you select or which password you pick to secure your wifi, it can be broken into.
Shared Proxy Servers / NAT
DHCP
IP Spoofing
Compromised Computer
If your computer gets infected by a Trojan, Rootkit, or computer virus, it is no longer under your control. A malicious user can upload, download and use your computer without your knowledge. In fact, this is what the majority of trojans typically do: Botnets are collections of subverted computers (the Dutch police uncovered a botnet consisting of 1.5 million infected computers) - it will be up to you and your legal counsel to prove that you have been a victim of a trojan or botnet subversion.
