German data protection regulator Johannes Casper has denied Facebook to collect and process Whatsapp user data. He said it is his job to prevent such black-box procedures. WhatsApp said that the decision was based on a fundamental misunderstanding of the effect and purpose of the new update. Casper has used his executive authorities to put a three-month ban on Facebook-owned WhatsApp. He would also seek an EU-wide ruling at the European Data Protection Board.
