• 10 nations tell Google of privacy concern on Buzz

NEW YORK — Officials from Germany, Canada, France and seven other countries are raising privacy concerns about Google’s mapping service and the company’s fumbled foray into social networking.

Although the concerns they raise are not new, the officials said the online search leader "too often" forgets people’s privacy rights as it rolls out new technologies.

(

The bulk of the complaints are over Buzz, which Google (Nasdaq: GOOG) launched in February as part of its Gmail service. Buzz quickly came under fire for automatically creating public circles of friends for users, based on their most frequent e-mail contacts. After complaints, the company apologized and made changes to the service.

But in the letter sent Monday to Google CEO Eric Schmidt, privacy and data-protection officials from the 10 countries said they are still "extremely concerned about how a product with such significant privacy issues was launched in the first place."

Google Street View, a mapping service that includes street-level photos taken by cameras mounted on cars that sweep through neighborhoods, is another area of concern. The officials complained that Google launched it in various countries without "due consideration of privacy and data protection laws and cultural norms."

"In that instance, you addressed privacy concerns related to such matters as the retention of unblurred facial images only after the fact, and there is continued concern about the adequacy of the information you provide before the images are captured," officials said in their letter, posted on the Web site of Canada’s privacy commissioner.

Google said it has "discussed all these issues publicly many times before and have nothing to add to today’s letter."

The other countries that signed the letter are Ireland, Israel, Italy, the Netherlands, New Zealand, Spain and the United Kingdom.

• Atheros Communications shares up after 1Q results
NEW YORK — Surprisingly upbeat first-quarter results sent shares of chip maker Atheros Communications Inc. up sharply Tuesday. Lazard Capital Markets analyst Daniel Amir lifted his price target for shares to $47 from $42 in a client note Tuesday.
