FB Like Button

Facebook Twitter

'Like' Button Follows Web Users.

FB investigation by Irish

Tracking performed by social networks. In this blog post I analyze methods of user tracking which are performed by popular social network websites such as Facebook , Twitter , Xing , and recently Google+ . Each of these social networks have buttons (called Like , Tweet , Visitors , and +1 buttons) which are installed on numerous websites. I try to put some light on the actions performed by those buttons and how they track users around the web, even when they don't click those buttons. All these buttons have one thing in common: they are embedded in websites all around the web and load resources (scripts, images, etc.) which are fetched from the social networking website or their content delivery partners. The website operator embedding these buttons does not have the complete control over what content is loaded in the context of the user's browser viewing the website.

In the next paragraphs I show some details about the code of these buttons and what happens when users view the webpage located at . Facebook Struggles to Explain Its Web-Tracking Practices. Facebook’s business is built on trust, but that trust has been shaken over the past few weeks by criticism and speculation regarding how it uses browser cookies to get data about users.

Facebook Struggles to Explain Its Web-Tracking Practices

A lack of thorough documentation explaining what each of its cookies does has led some observers to assume that the company is tracking offsite browsing behavior in order to target ads. Facebook fixes ID cookie glitch. Cookies espions : Facebook réfute, avant pourtant de corriger. With ‘frictionless sharing,’ Facebook and news orgs push boundaries of online privacy. Facebook again may have gone too far in its quest to make privacy obsolete, and this time some news organizations could get burned by going along with it.

With ‘frictionless sharing,’ Facebook and news orgs push boundaries of online privacy

Facebook spent years making it easier for us to share by building its network and placing “Like” buttons across the Web. Its latest idea goes much further, turning sharing into a thoughtless process in which everything we read, watch or listen to is shared with our friends automatically. Encouraging sharing is great. Making sharing easier is even better. But this is much more than that. News organizations and other content companies are eagerly accompanying Facebook down this path. After disclosing required permissions up front, apps like Washington Post Social Reader automatically share all reading activity. New Facebook-based apps like Washington Post Social Reader, and similar ones from The Guardian and The Daily encourage Facebook users to read their stories and pump all that reading activity out to their friends.

And I believe that you believe that argument.

Facebook Disconnect

I believe even that Zuckerberg believes it. Very rarely is there a Gargamoyle sitting in a tower plotting the downfall of the smurfs. Most times it's just someone with the best of intentions. In this case your argument is that you just want the information so as to provide people what they want. Okay - fair enough. And next comes the only real reply that's available to you. Now - you don't state anything directly paternalistic in your reply. Sorry you need to try harder to see this from the other point of view. The first of these signs is the fact that you don't address the very obvious counter argument I just laid out. The second such sign of critical impairment is the fact that you are marginalising your opponents as "tin foil hat" people - or as ignorants who couldn't possibly understand.

Facebook denies cookie tracking allegations. Update: Facebook fixes cookie behavior after logging out.

Facebook denies cookie tracking allegations

Over the weekend, self-proclaimed hacker Nik Cubrilovic accused Facebook of tracking its users even if they log out of the social network. The company has denied the claims and has offered an explanation as to why its cookies behave the way they do. For reference, here's what I wrote based on Cubrilovic's findings: After running a series of tests analyzing the HTTP headers on requests sent by browsers to, he discovered that Facebook alters its tracking cookies the moment you log out, instead of deleting them. Since your uniquely identifying account information is still present in these cookies, Facebook can continue to track you. I also said I contacted Facebook for more information on this issue.

In short, Bejar is saying Cubrilovic raises some good points and has some interesting findings, but reaches incorrect conclusions. I'd like to thank Bejar for posting the comment on my blog.

FB Is Tracking Your Every Move

Facebook Tracks and Traces Everyone: Like This! by Arnold Roosendaal. TNO Information and Communication Technology in DelftNovember 30, 2010 Tilburg Law School Legal Studies Research Paper Series No. 03/2011 Abstract: Numerous websites have implemented the Facebook Like button to let Facebook members share their interests, therewith promoting websites or news items.
