Facebook has stated in a post on their blog that it will block Google’s Friend Connect service from accessing data on its social network site. The company has motivated its decision by saying that Friend Connect does not comply with their privacy policy.

The main issue is the fact that, according to them, Google’s service is allowing third party sites to have access to the user information that is transmitted while exporting profile information.

The decision comes as a blow to the joint effort of the three companies, Facebook, Google and MySpace, to increase data portability over the internet. Each of the companies has released its own service, and all have hailed each other’s initiative. It is not known how much banning Google from Facebook will hurt the project, nor whether it will give MySpace a reason to do the same thing.

Facebook has said that Google will be allowed access again as soon as it will solve the issues, but the search giant replied that it doesn’t understand what exactly it is expected to do.

It is interesting to take notice of the fact that Facebook has launched its own service, called Facebook Connect, three days before Google, and that its specifications are apparently pretty similar to those of its competitor.

Friend Connect is a service that allows site users to add a tiny bit of code to their web pages, code that will allow the users to import their profile information from other sites like, for example, MySpace.

The service is designed to add social capabilities even to sites that lack the resources to do so independently. For the time being, only a few sites have been granted access to Google’s code, but the number will increase as the service proves to work properly.
