Google committed a "significant breach" of the Data Protection laws when its Street View cars grabbed personal data but the Internet giant will not be fined, the information commissioner of Britain said Wednesday.
Britain is the latest in a series of countries to condemn Google after the cars, which take photos for the search engine's free online mapping service, mistakenly picked up private emails and passwords from wireless networks.
Information Commissioner Christopher Graham said Google's British arm will now be subjected to an audit but it will escape a fine so long as the firm vows not to commit similar privacy breaches in future.
"It is my view that the collection of this information was not fair or lawful and constitutes a significant breach of the first principle of the Data Protection Act," Graham said in a statement.
He said an investigation by the independent authority found Google's Street View cars had collected "fragments of personal data" from wireless networks which it had now been ordered to delete.
"Google UK will be subject to an audit and must sign an undertaking to ensure data protection breaches do not occur again or they will face enforcement action."
The statement said Graham had rejected calls to fine Google over the breaches "but is well placed to take further regulatory action if the undertaking is not fully complied with."
Google apologised for collecting the data and said it was working with British authorities to ensure that it did not happen again. It first revealed the problem in May.
"We are profoundly sorry for mistakenly collecting payload data in the UK from unencrypted wireless networks," Peter Fleischer, Google's global privacy counsel, said in a statement.
"As we have said before, we did not want this data, have never used any of it in our products or services, and have sought to delete it as quickly as possible."
But Big Brother Watch, a British pressure group that fights invasion of privacy, said it was "disgraceful" that the watchdog had not fined Google.
"If Google can harvest the personal information of thousands of people and get off scot-free, then the (information commissioner) plainly has a contempt for privacy," the group's director Alex Deane said in a statement.
The Californian company has faced strong resistance in some countries to Street View -- which enables Internet users to obtain a virtual image of a whole street from every angle -- due to concerns over invasion of privacy.
Italian prosecutors said last week they had launched an investigation against Google. Spain filed suit against the firm earlier in October while in September Czech authorities banned Google from collecting Street View data.
The US Federal Trade Commission said last week that it was ending its inquiry into Street View, although Google is facing civil suits in several US states demanding millions of dollars in damages.
