Protecting Privacy in Signal Processing

While not explicitly stated in the U.S. Constitution, the rights of privacy for many aspects of our lives including religious beliefs, personal possession, and personal information are protected under the Bill of Rights. Nonetheless, news about different forms of privacy invasion has become a daily affair. From the sale of personal information to identity theft, from Google and YouTube surrendering user data to the mining of phone metadata by the National Security Agency, the number of ways that our privacy can be invaded seems to increase at an alarming rate.
