Web Firms, Advocates Draw Lines in Privacy Fight

But as the Internet becomes the backbone for an ever-growing body of personal data, including sensitive information such as healthcare records, many observers are expecting Congress to consider an update of the 1974 Privacy Act to add provisions relating to online data collection.
In a panel discussion on privacy here at the Hyatt Regency on Capitol Hill, Mike Hintze, Microsoft's (NASDAQ: MSFT) associate general counsel, expressed the company's cautious support for reforms to privacy law.
"We've been an advocate of federal privacy legislation for a number of years, and we would actually like to see a real comprehensive approach to privacy legislation that creates some baseline standards across industries and across the country," Hintze said.
But tech companies whose revenue streams in advertising and other areas are increasingly tied to the quality of their data-collection operations, and would be wary of privacy legislation with specific restrictive conditions for online information.
"What we are always up against is trying to make sure that we're not stifling innovation and research capacity to be able to offer improvements that we wouldn't have been able to foresee without the use of data," said Anne Toth, Yahoo's (NASDAQ: YHOO) vice president of policy and head of privacy.
"Prescriptiveness can be helpful, baselines can be helpful, but flexibility, and recognizing that technology is a very fast-moving train [is critical]," Toth added.
But privacy advocates warn that government might need to play a stronger role in ensuring that companies can't collect sensitive data such as genetic information, as well as establishing standards for how they anonymize the data that they do collect.
"There are a lot of intriguing myths about privacy and anonymity," said Pam Dixon, cofounder and executive director of the World Privacy Forum. "One of the myths is that if you just simply take a database -- and all databases are created kind of equally -- and you remove [personally identifiable information], then you've done your job anonymizing it. And that's actually not true."
Companies like Microsoft, Google (NASDAQ: GOOG) and Yahoo, which collect massive amounts of data both from their search engines and from other account-based services, make a point of touting their privacy safeguards such as deleting their server logs and deleting parts of Internet protocol addresses to ensure that their users remain anonymous.
[cob:Special_Report]Yahoo, for instance, recently made a splash when it announced that it would anonymize IP addresses after 90 days, down from its previous retention window of 13 months.
Microsoft keeps IP addresses for a longer period of time (18 months), but then deletes them entirely, rather than just erasing the final numbers in the string. Hintze also said that the company employs a technique called a one-way hash at the point search data is collected to keep it separate from any personal information it might collect.
"Giving users an assurance of their privacy is beneficial to us as a company," Hintze said.
