Clearer rules on customers' rights to privacy are laid down in new EU telecoms rules, which are due to be implemented in national law in all Member States by 25 May 2011. The rules require operators to secure personal data properly and to inform their customers and data protection authorities promptly when personal data is lost. The rules also require Internet users to be better informed about data other parties store or access on their devices and improve the tools for fighting spam. This MEMO gives further details about these new privacy rules.
