Hugh Pickens writes "The NY Times reports that in the next few years, HTML5 will provide a powerful new suite of capabilities to Web developers that could give marketers and advertisers access to many more details about computer users' online activities. The new Web language and its additional features present more tracking opportunities because the technology uses a process in which large amounts of data can be collected and stored on the user's hard drive while online. Because of that process, advertisers and others could, experts say, see weeks or even months of personal data that could include a user's location, time zone, photographs, text from blogs, shopping cart contents, e-mails and a history of the Web pages visited. 'HTML5 opens Pandora's box of tracking in the Internet,' says Pam Dixon, the executive director of the World Privacy Forum. Meanwhile Ian Jacobs, head of communications at the World Wide Web consortium, says the development process for HTML5 will include a public review. 'There is accountability,' Jacobs says. 'This is not a secret cabal for global adoption of these core standards.'"
