The Carnegie Mellon University Usable Privacy and Security Laboratory (CUPS) was established in the Spring of 2004 to bring together Carnegie Mellon University researchers working on a diverse set of projects related to understanding and improving the usability of privacy and security software and systems. The privacy and security research community has become increasingly aware that usability problems severely impact the effectiveness of mechanisms designed to provide security and privacy in software systems. Indeed, one of the four grand research challenges in information security and assurance identified by the Computing Research Association in 2003 is: "Give end-users security controls they can understand and privacy they can control for the dynamic, pervasive computing environments of the future."
