Accessibility concerns compound the already-considerable difficulties of building systems that provide usable privacy and security. In addition to facing common concerns regarding the semantics of privacy and security tools, people with disabilities face accessibility obstacles, such as the inaccessibility of CAPTCHAs, phishing toolbars, verification images, and other displays that rely upon vi...

This chapter describes a privacy-secure digital watermarking scheme for fair content trading against cybercrime on digital content piracy and privacy leakage. Conventional digital watermarking schemes are effective only for providers since privacy of a client is not concerned though content is protected. Provider’s security as well as client’s security need to be considered to enhance security ...

Increasing collection of individuals’ information has led to several security and privacy issues, such as identity theft and targeted marketing. These risks are further heightened in the mobile realm as data collection can occur continuously and ubiquitously. Most existing research considers threats to privacy and security as separate concerns, resulting in separate research streams. However, f...

As our world becomes more computerized and interconnected, computer security and privacy will continue to increase in importance. In this paper, I overview several computer security and privacy challenges faced by end users of the technologies we build, and how we can design and build technologies that better match user expectations with respect to security and privacy. I close with open challe...

With their increasing popularity in cryptosystems, biometrics have attracted more and more attention from the information security community. However, how to handle the relevant privacy concerns remains to be troublesome. In this paper, we propose a novel security model to formalize the privacy concerns in biometric-based remote authentication schemes. Our security model covers a number of prac...
