The regulators, led by France's Commission Nationale de l'Informatique (CNIL), have spent several months investigating the policy, which basically allows Google to mash up all its previous 60 policies into one document and grab data on folks from across their services.
The data authorities said today in a CNIL announcement that Google needed to make the new terms of their over-arching policy clearer for users and give those users an opt-out option for each product so they can stop information being taken from one to the other.
A letter has been sent to the search giant outlining the changes that are wanted, signed by 27 out of the 29 countries' regulators involved. But although the EU is asking for alterations to the policy, it has not yet fined or threatened to fine the firm or accused it of breaking the law.
Google's Peter Fleischer, global privacy counsel, said that it was reviewing the findings.
CNIL, which has been an avid critic of the new policy, headed up the probe for Europe's G29 countries and questioned Mountain View twice about the changes, but said the firm did not give "satisfactory answers" to its concerns.
Nevertheless, by analysing all the documents and mechanisms of the new policy, the data protection authorities decided that the web giant did not do enough to protect people's privacy.
Google users can't figure out what categories of their personal information are being snaffled by the firm and what purpose that data is used for under the current policy, the regulators said, claiming that the policy made no distinction between the results of a search query and a credit card number.
The authorities also said that users had no control over the combination of their data across Google products like Gmail and YouTube, whether it would be used for product development or advertising or research. Google refused to give specific retention periods to CNIL, but the investigation found that the scope of data gathering was pretty broad and the information was kept for quite a while.
"The mere consultation of a website including a ‘+1' button is recorded and kept during at least 18 months and can be associated with the uses of Google's services," they said. "Data collected with the DoubleClick cookie are associated to a identifying number valid during two years and renewable."
Several of the recommendations are also backed by members of the Asia Pacific Privacy Authorities and Canada's federal privacy commissioner has similar concerns about Google, they added.
The web behemoth seems incapable of turning around these days without running into another regulatory probe. Google has just finished with a Federal Trade Commission case over ignoring do-no-track in Safari browsers, the EU is in the middle of an antitrust case that's analysing whether the firm uses its search advertising to favour its own services over competitors and that whole Street View data slurp stuff just goes on and on.
The UK ICO for its part had this to say in a statement supplied to the Reg:
We await Google's response which will be considered by the Commission Nationale de l'information et des liberties (CNIL), on behalf of the ICO and the other European data protection regulators. A decision will then be made on whether further action is required.
