facebook and the computer imprint

[zak]

recently my sister suddenly was not able to browse any site related to facebook and even can't display the facebook.com,
after formatting the hard disk and upgrading the ie6 to ie8 facebook run shortly for 1 minute and then it is blocked. she installed Opera and Chrome and facebook displayed for 1 minute then blocked. she can browse facebook using anonymizers, and there are 3 of other users who are using the same router with different computers who can access facebook normaly. i searched the web and many people have the same problem and the solution sucess for one does not work for another.
so the only result i can imagine that facebook site have a record of my sister computer such as a hardware number like the finger imprint; i imagine that she talk something bad like a spam against someone and he report that to facebook. then they block her computer from accessing facebook depending on her computer imprint.
the computer imprint used in some software passwords in wich if you even changed any hardware in your computer then you need a new password.
so i can say upon this analysis that every one going to facebook are completely exposed whether you are logged in or not, just they get your computer imprint and compare it to your big record in facebook database.
think of this with other sites. it is like wearing a long red hat with a flag over the hat and walking in the street , every one will know you.

PS: other possibility is the IP checking, ....

It is strange. If your sister is somewhere banned they should report when she try to login or use Facebook.

Anyway, it can be your MAC address that is used to identify your sister computer.
It is a unique number that identify your network card.
It is included in the header of every network packed sent over network (whatever network)

Some computer bios let change the Mac address.

I have nothing to do with facebook or twitter.

And, I don't want anything to do with them.

Maybe it is my imagination.

But, it seems that when I am trying to connect to many sites, first, at the bottom of the screen I see,

"Connecting to facebook.com", or,

"Transferring data from twitter.com".

Great.

So, maybe soon, if, for instance you are banned by facebook, then, you won't be able to connect to anything.

And, since facebook has so much of the money, no one will regulate it, yes or no?

The organization reflects the head, right?

Didn't Mark Zuckerberg, like Bill Gates, attend Harvard?

Didn't he have to pay someone else approximately 60 million dollars for stealing the idea for facebook?

It seems that Harvard graduates are very good-hearted people, doesn't it?

They must have been raised that way, correct?

No notification of an accusation. No hearing. No trial. No right to confront the accuser. No right to present evidence. No right to appeal. No notification of banning. The only way you find out is when you can no longer connect. That doesn't sound like the actions of a police state, does it? But, that's what happens with a corporation. Since, it is non-governmental, it can do almost anything it wants. What laws govern how it treats its users? I think almost none do. So, as long as the profits keep coming in, what motivation does it have to treat people fairly? And, I just read that facebook doubled its revenue in the first half of 2011.

So, if somehow facebook is reading some hardware ID, what recourse does the victim have? I guess she could buy another computer, and create a new identity, at least for now. But, maybe in the future, when you buy a new computer, your unique planetary ID will be burned into it, the first time you use it (or it will refuse to function).

Maybe I am too paranoid. But, throughout history, how many people thought that they might be too paranoid, only later to find out that they weren't paranoid at all, they were exactly correct?

thanks Eros, the MAC address is a good possibility i will try to change it when i visit them, a good description of the same problem reported here .. (http://forums.cnet.com/7723-6142_102-507580.html). and many other forums.
yes Dan they can govern the world, and dictate any one, and because they are extremely rich they don't feel necessarily to say sorry or to send a message that you are banned, someone can say you are talking about conspiracy theory, but it is the nature of the 40% of the people to be conspirators. and the nature of 100% of the banks to be conspirators, which are inhuman by nature; the proof: just try to not pay your monthly duty to the bank due to a sudden problem in your life and see that they will make you starve to death without any sorrow. and this is must not be the situation with human organizations.

[danbaron]

and this is must not be the situation with human organizations.

Sometimes I think I'm the only one who feels like me.

So, when I read zak, I feel a lot better.

The banks will charge us 15% on interest on credit cards, but they will pay us 1% on savings accounts.

that they will make you starve to death without any sorrow

Currently, the people have no power against injustice.

And, they are brainwashed not to realize what the rich are doing to them.

Few even realize that they should be angry.

They are like sheep docilely being led to slaughter.

The media, owned by the rich, hypnotizes everyone into thinking everyone is happy, everything is fair, and everything should remain exactly as it is.

Concerning how facebook recognizes a particular computer:

I don't know anything about this stuff.

Say, it is something in ROM.

Maybe I'm wrong, but it seems to me that Windows would read it upon start-up.

In that case, I think Windows must keep the value/values somewhere in RAM.

And, facebook must request the information from Windows, yes?

I can't imagine facebook accessing the information without going through Windows.

I guess the question is, what values does Windows store which identify a particular computer (maybe it is only the MAC address)?

Then, maybe using the Windows API, couldn't you find the locations where these values are stored, and make a little program to POKE different values in them?

(Or, like Eros said, if it is only the MAC address, and the BIOS will let you change it, then, the problem is solved.)

Maybe you could POKE different random values there each time.

It's her computer right, she can do what she wants with it, yes or no?

Maybe my idea is what you meant by, "anonymizers".

[zak]

Dan ,the anonymizer rarely i am using is a site... (http://anonymizer.ru/). just write the address you want to access at the top right corner then press Enter, i have faced a few situations in wich a site wich does'nt displayed but displayed using the anonymizer. but you can't log in using that site unless you pay. also there are many ip concealers software which i think belong to the same company. using www.whatismyip.com (http://www.whatismyip.com) you can know what is your ip address.

[danbaron]

I looked in my BIOS, and the only ID I could find is under CMOS Setup, System S/N.

It consists of a mix of 7 uppercase letters and 15 digits.

So, there could be 8,031,810,176,000,000,000,000,000 different combinations (26^7*10^15) of S/Ns.

I don't know if that is the ID facebook uses, but, it seems that the System S/N could absolutely be unique.

In fact, if the population of an average inhabited planet is 7 billion, and each inhabitant has one computer, then, that number of combinations could provide a unique S/N for every computer on 1,147,401,453,714,285 and 5/7 inhabited planets.

The upper estimate on the number of stars in our galaxy (Milky Way), is 4*10^11.

http://en.wikipedia.org/wiki/Milky_Way

If the average star has 10 inhabited planets (I think much too high), then, the number of inhabited planets in our galaxy is 4*10^12.

In that case, the number of possible different S/Ns, would be enough for every computer in 286 and 186017/218750 Milky Ways.

I dont use facebook and twitter at all but one my friend told me what is
all about .
There is a problem with trojans and keylogers -viruses.

One reason more to not use facebook and twitter.

[Michael Clease]

The thing to remember is that the mac address is for the router and not the computer its only the router that knows what machine is talking to the internet, its two separate networks.

Change the router and and that will change the mac.

Mac addresses can spoofed...

[danbaron]

Even in this forum, when I go from one page to another, sometimes at the bottom of the screen, I can see,

"Connecting to www.facebook.com",

or,

"Connecting to connect.facebook.net".

I have no idea why that is.
