ABSTRACT
Privacy is the “the interest that individuals have in sustaining a personal space free from interference by other people and organizations.” In many countries, privacy is enforced by law. This chapter look at the types of controls that can be used to protect privacy, and the effectiveness of such controls Differential privacy is a relatively new technique used to obfuscate a data set by introducing a certain amount of error into the data set while allowing the entity querying the data set to make relevant statistical inferences. The California Online Privacy Protection Act is the California law that requires websites to post a privacy policy and comply with what the company posts, including whether websites track users across their site and other party’s websites. The Children’s Online Privacy Protection Act is a US federal law that applies to websites that collect data from children under the age of 13.
