Is it possible to take advantage of the benefits of data collection-and mitigate risks-for both companies and customers? Most consumers are not very skilled at evaluating privacy risks; they're either unable to determine the cost of sharing personal data online or unaware of what they're sharing. (Doesn't everyone scroll down without reading to click "I accept"?)

In today's digital surveillance economy, there are no clear-cut best practices or guidelines. Gathering and using information can help customers-we see that in personalization and autofill of online forms. But companies must act in the best interest of their customers and treat the sensitive information users give them with the ethical care of doctors, lawyers, and financial advisers. The challenges of operating in a digital ecosystem aren't going away.
