If you expect privacy when you’re online, if you think you can anonymously use the Internet without the government finding out who you are and what you’ve accessed, then you’re being unreasonable. That’s what the Ontario Court of Appeals has said, making them the highest court in Canada to rule that privacy laws don’t protect Canadians’ names and addresses from warrantless requests by police.
… police are now able to invade a person’s home and seize their property based on the fact that an I.P. address they rent is linked to a crime. An I.P. address is not a person. Often, a number of people under one roof use the same I.P. address. An I.P. address isn’t a fingerprint either. If a wi-fi connection is unprotected, anyone nearby can use it. I.P. spoofing allows users to hide their real I.P. addresses and use a fake one. If these fake addresses ever match a real one assigned to a third party, police investigations may incriminate innocent people.
Criminals who know they are doing wrong online will grow ever-more capable of dancing around I.P.-based identification. The rest of us will grow ever more likely of turning up as “false-positives.”
