How are consumers and companies addressing personal-data privacy?

"Increasingly, consumers are fighting to regain control of personal data and how that information is used. Privacy advocates are working to block sales of information collected by governments and corporations. For example, they want to prevent state governments from selling driver’s license information and supermarkets from collecting and selling information gathered when shoppers use barcoded plastic discount cards. With information about their buying habits, advertisers can target consumers for specific marketing programs. The challenge to companies is to find a balance between collecting the information they need while at the same time protecting individual consumer rights. Most registration and warranty forms that ask questions about income and interests have a box for consumers to check to prevent the company from selling their names. Many companies now state in their privacy policies that they will not abuse the information they collect. Regulators are taking action against companies that fail to respect consumer privacy."
