European data protection officials are drafting plans to censure Google over its online privacy policy if the company does not meet the demands of regulators to revise it.

In a two-day closed-door meeting this week in Brussels of the European Union’s 27 national data protection officials, the group mapped a preliminary strategy, including the possibility of testing Google’s compliance with national privacy laws in countries like Ireland, Belgium and Finland, where the company operates data centers. That was the word from a person close to the discussions, who spoke on condition of anonymity.

The group may issue a public statement next week on the matter.

The group is focusing on new guidelines Google adopted this year for collecting information on individuals. Under the new policy, when people are logged into a Google account, the company can use information shared on one service in other Google services. For example, Google could show people an ad on YouTube based on what they have searched for, or fix the spelling of a friend’s name in a Google search based on information from Gmail.

When the guidelines were announced, they were sharply criticized in Europe. Data protection officials from various countries asked the French regulator, C.N.I.L., to study them. In mid-October, that regulator released a report criticizing the guidelines as allowing an “uncontrolled combination of data.”
