Privacy question

What can an ISP/server tell about your internet activity from the following? Is it enough to reconstruct every page you visited, what you did on them etc?

source and destination IP addresses
source and destination port numbers
protocol type
number of octets of data
number of packets of data

Thanks.

No, they don't have to "reconstruct" a page... They have the pages you visited already, so they can just look at thier logs, and see that ip X asked for this and that, and blam, youre busted.

Sorry can you elaborate a little I don't quite understand this answer? You're saying that they can look at which pages someone visited from the data mentioned? Can they tell if you changed something on the page if the page itself doesn't have a method of recording this?

They see basically everything you see, lets put it that way.

Same goes for search engines (except it's only what you search/look at on the search website, not everything you view in general)

As waffle said, they see everything, and they just need the requests from your ip to their server.

When you type h ttp://www. techist.com, your computer asks the isps servers to go and get that page and put it on your screen. Same time, A log is writen on the server thAt says on this time and date, ip 192.168.1.102 asked for techist.com.

So they know where you go and what time you did it at, from their server logs.

No, they can't tell you changed a page, as they only show where you go, and what you ask of their servers. Depending on their log keeping, they might have the ability to see what you send to and from you to that pages ip.
