Facebook has long been difficulties with the issue of data protection and privacy of its users. Zukerberg While working to improve the appearance and environment introduces a "revolutionary" changes, policy issues again in the foreground.
Nik Cubrilovic self-proclaimed hacker has conducted many tests and analysis of HTTP request headers that browsers send to facebook.com, and also found that Facebook, instead of deleting, changing your "cookies" instantly when you log off from social networks, reports the blog portal ZDNet.
As your unique user information remains in the "cookie" on Facebook and you can follow. So if you think you will click on "log out" help, think again, say from ZDNet. If you go to a page that contains the Facebook plugin, your browser will continue to send confidential information in Palo Alto.
"When my browser log off from Facebook, each time you visit a page that has" like "or" share "button, Facebook continues to send confidential information,
including my ID, "said Cubrilovic, adding that all this can be checked by using any browser that contains the developer tools.
Facebook Engineers: We do not mis-use "cookie"
Reacted to these accusations is Facebook engineer Arturo Bejar and told to "hook" that stays on after you are log out the profile is used to track user habits.
"We do not use our 'cookies' in order to better qualify or advertising to sell information to third parties. I've heard so many times that our business sales information, but it's just not true. We use our 'cookies' while you are logged in order to personalize your experience and even to improve it, "the letter Arturo Bejar, which coincides with what Facebook says all the time.
Google is doing it for a long time
The same thing is now detected in Facebook, Google has been doing for years. If you were logged into Gmail, Maps, Documents and even visit the site that incorporates the code from Google, such as google anylitics, a free service that monitors traffic, Google will know where you're moving.
"The difference between Facebook and Google in this case is that more and more Web site has social benefits (widgets) that put them Facebook code. If you were logged on Facebook and you have the 'cookie' written code of your user account, it will use the mentioned code very easily be able to track your web surfing.
The biggest problem of monitoring is that Facebook is to some extent Google may remain anonymous because the creation account does not have to enter data while the actual users of the most popular social network usually put their name and some unique information.
They want to know more about customers
Knowing all of this raises the question "Why Facebook is doing and what happens to the information taken"?
Their intention is to learn as much about each user in order to send based on advertising. So things work on the internet and this is nothing new. The same can be done by the police. Specifically, the police must not only follow you through your relationship, then the one that carries your name. If you go to a friend or use a free wireless network for reporting, the police will make you very hard to find. But, hypothetically speaking of the police could search a list of the Facebook page where you were and get them thanks Facebook "cookie" which followed in your movement.
Solution:
A logical question arises: How to get rid of "cookies" and still you can use the Facebook service?
In order to avoid sending your private information, and still be able to use his, now maybe a little less to your favorite social network, you can delete the "cookies" each time after you log off from it.
Facebook: We do not use the information for targeted advertising
Facebook is officially recognized and reacted to data on the movement of users on the web due to Facebook when the user is logged out, but that this data is not misused and that the data they receive quickly deleted.
In a statement, which was passed Wall Street Journal, one of the employees in Facebook, Arturo Behar says that data is sent over the way the system is based is set and all cookies that are associated with Facebook.com sent automatically every time you see like button.
"The onus is on us to take all the data and delete them. What really matters is what we as a company and say what we stand behind," he said and stressed that this information is not used for targeted advertising, as well as to look for ways that this data is not sent, but "it would take."
