To implement Facebook plans to the Foundation, we lay UIDs encrypted in the next few weeks and then adding support for encryption after in-house developers and the larger Web community, Mike Vernal, a Facebook engineer said in a blog post. "While the initial press reports the implications of sharing a UID greatly exaggerated, we this problem seriously nehmen.Unsere policy already clearly UIDs can be shared with ad networks and data brokers, but we realize that some developers were accidentally this exchange of information", he wrote.
The proposed amendment is aimed at preventing unintended sharing of UIDs, but won't stop deliberate UID Exchange in violation of Facebook policy. "While the unintended sharing of this information on Facebook, this proposal will address the underlying problem data exchange via HTTP header is a Web-wide problem," wrote vernal. "We are happy to help us to work with the Web standards community and browser suppliers in the coming months to address this issue," he said.
