The Federal Trade Commission has issued revised guidelines for behavioral advertising, but the rules aren't likely to be the last word on the issue.

The FTC released new rules Thursday to guide the collection, storage, and sharing of information on Internet users. The guidelines expand the rules to include ISPs and mobile service providers. They tell companies to inform users when their data is collected and to provide consumers with the opportunity to refuse data collection by opting out.

The FTC has urged companies to separate notifications and opt-out opportunities from overall privacy policies and make them easy for users to spot. It has advised companies to gain consent before accessing particularly sensitive information about health, children, and Social Security numbers. It also urged companies to protect consumers' data with adequate security measures. Finally, it has asked companies to inform consumers of any changes to data collection practices.
