While I understand that cookies are generally safe and they are only used to track certain information, I hear that some people are concerned about cookies undermining their privacy. Can someone explain to me in what way a cookie may undermine someone’s privacy?
I do not know exactly but I think everyone might know about all web sites you have visited. If that is not something you would like to protect you should be patient
that is if someone gains access to your computer directly however. what about privacy concerns over the internet, how is my privacy affected by the use of cookies?
It isn’t at all. Anyone who complains about cookies should be ignored and hit with a whale.
A website can use cookies to track everything you do on that website, which that website could not do without cookies. That’s not a concern for most people though.
Third party cookies concern more people. Web analytics providers and ad servers can use cookies to keep track of websites you visit and deduce information from that. For example, Google has its ads on many websites, so it has the ability to keep track of your browsing habits fairly well.
