PARIS, Feb. 19  European governments are preparing legislation to require companies to keep detailed data about people’s Internet and phone use that goes beyond what the countries will be required to do under a European Union directive.

In Germany, a proposal from the Ministry of Justice would essentially prohibit using false information to create an e-mail account, making the standard Internet practice of creating accounts with pseudonyms illegal.

A draft law in the Netherlands would likewise go further than the European Union requires, in this case by requiring phone companies to save records of a caller’s precise location during an entire mobile phone conversation.

Even now, Internet service providers in Europe divulge customer information  which they normally keep on hand for about three months, for billing purposes  to police officials with legally valid orders on a routine basis, said Peter Fleischer, the Paris-based European privacy counsel for Google. The data concerns how the communication was sent and by whom but not its content.
