People around the world are concerned that more and more of their personal data is on the Internet, where it's easy to find, copy, and link up with other data. What people most often want is a sense of control over their data. Many people feel that this control is a fundamental human right, or an essential part of your property rights to your data.
Regulators are starting to respond to these concerns. Because societies around the world have different cultural norms and governments have different priorities, there will not be a single worldwide regulatory regime. However, it does seem possible to have a single set of basic technical mechanisms that support regulation.
