Your moods. Stroz Associates in New York markets software to scour employee e-mail, looking for mood swings identified by changes in vocabulary patterns. The goal: to alert companies that an employee is in danger of becoming violent.
Your genes. Under a proposed Oregon law, genetic information would no longer be considered private property once it is separated from that person's identity, either through encryption or anonymous research.
Your face. Without their knowledge, fans entering this year's Super Bowl in Tampa were scanned by cameras and their facial images compared against a computer file of known criminals. Facing a public backlash, officials for the the 2002 Winter Olympics in Salt Lake City say they have decided not to use the technology.
Your Internet activity. The FBI uses computer programs dubbed Carnivore and Etherpeek that let agents monitor e-mails, Web pages, chat room conversations and other online signals going to or from a suspect under investigation.
Your financial data. Banks, insurance companies and mortgage companies will limit the sale and spread of your personal financial data, but only if you "opt out" by specifically telling the companies not to share that information. Otherwise, your financial profile can be sold to others.
Your driving habits. In an experiment that could spread nationwide, the National Park Service plans to use radar cameras on the George Washington Parkway in northern Virginia to photograph speeders and mail them tickets. Cameras already are used on Florida roads to catch toll-jumpers.
Your location. New-generation cell phones and new satellite-based services for vehicles act as homing devices that can pinpoint your geographic location.
Your e-mail and voice mail at work. The majority of larger companies can scan computer and phone messages of employees to monitor such matters as work productivity, security of company secrets and potential discrimination and harassment.
Your "anonymous" online comments. Internet users that typically sign on with fictitious names to company message boards run by Yahoo and other providers may assume they are offering anonymous comments. But corporate lawyers repeatedly have had success extracting the identity of users whose comments are considered unfavorable to a company.
Your identity. Nearly 2,000 consumers contact the Federal Trade Commission every week to report that they have been victims of identity theft.
