So if the current model is broken, how can it be fixed? There are two broad answers: rules and tools.
Rules would mean new regulations. And Congress and the Federal Trade Commission are looking at further rules that could limit how personal information is used.

Google, Facebook and Twitter are evidence of the trend, and so are legions of start-ups seeking riches in fields like social networking, cloud computing and smartphone applications.
