The gigabyte storage capacity and long memory of Google's planned web-based email service are making it a big target for privacy campaigners, while the name, Gmail, could soon be the subject of a trademark dispute.
A coalition of 28 privacy and civil liberties groups wrote a letter to Google founders Sergey Brin and Larry Page on Tuesday urging them to reconsider the service, which they said sets potentially dangerous precedents for the automated scanning of private communications. The service may conflict with European privacy laws, and should be suspended until privacy issues are addressed, they wrote.
The letter's signatories include the World Privacy Forum, the Privacy Rights Clearinghouse, Bits of Freedom, the Consumer Federation of America, the Electronic Privacy Information Center, the Foundation for Information Policy Research and Privacy International.
When Google announced the Gmail service on 31 March, the company said it will scan the text of all incoming email in order to place appropriate advertisements. This is a bad idea, according to the privacy campaigners, because "The scanning of confidential email violates the implicit trust of an email service provider."
Many email systems already scan message content in an effort to block spam, but inserting ads in incoming email is fundamentally different than removing harmful viruses and unwanted spam, the campaigners said. Inserting ads on the fly requires a chain of directories, databases and logs, and a long memory. Those auditing trails could be correlated with data collected from Google's search site, or social networking site Orkut, they said.
Google Vice President of Engineering Wayne Rosing sought to reassure the campaigners: The Gmail user's name is not sent to the ad server, and when the system scans the email, it does not look at the To or From fields, only the subject and body of the mail, he said in an interview.
Whatever the details of Gmail's scanning process, it sets dangerous precedents and reduces users' expectations of the privacy of email, the civil liberties groups said.
"These precedents may be adopted by other companies and governments and may persist long after Google is gone," they said.
One of the letter's signatories emphasised this danger in a phone interview.
"The mail is not just being scanned, it's also being indexed, and governments might want to know if a word is in the index, and if so, who used it," said Maurice Wessling of Bits of Freedom, a civil liberties organisation in Amsterdam.
"The unlimited period for data retention poses unnecessary risks of misuse," they wrote, adding that Google's policies on retaining data and correlating it between business units are problematic, lacking clarity and being too broad in scope. The company should set clear limits on how long it will retain user account, email and transactional data, and provide clear written policies about data sharing, they wrote.
Setting out these policies clearly and precisely is vital if Google is to remain within the law: As it stands, they said, Gmail may conflict with a European Union directive on privacy that users' consent must be informed, specific and unambiguous.
Rosing said Google believes its policies are clearly laid out and protect users' privacy. "We're committed to protecting user privacy to the maximum extent that we can do while at the same time abiding by the law," he said.
However good Google's intentions, they're worth nothing if the company folds, said one observer.
No one knows the likelihood of Google going under, since the company is not quoted on the stock exchange and nobody knows about its financial data, Mock wrote in an email.
Google may have some other protecting to do. Days after it announced the details of Gmail, its trademark is already being disputed. Following Google's use of the name Gmail in a press release, financial service provider The Market Age registered its interest in the name with the US Patent and Trademark Office, the British company said in a news release Tuesday.
The Market Age launched a web-based email service called Gmail in mid-2002 as part of an online share price and currency exchange rate analysis service offered by subsidiary Pronet Analytics.com , it said. Pronet's Gmail allows subscribers to annotate stock price charts and forward them by email. The company is seeking advice on how to protect its intellectual property, it said.
