What is Identification and Authentication

Many measures that enhance information security and privacy exist. Because these measures involve humans in various ways, their effectiveness depends on the human factor. This chapter reviews basic components of information security and privacy with an emphasis on human factors issues. It provides an overview of empirical investigations that have been conducted regarding the usability of security and privacy measures. These studies show that users have difficulty interacting with complex interfaces and that users’ performance can be improved by incorporating human factors principles into the designs. The authors conclude by discussing how human factors analyses can lead to the design of usable systems for information security and privacy assurance.
