The following topics are dealt with: secure computing; software engineering for security; data privacy; risk management; and trust and security models.
Summary form only given. Scantegrity II, an enhancement for optical scan voting systems, achieves a level of integrity unprecedented in scalable elections. It uses unique confirmation codes that are printed on ballots in invisible ink. Voters mark their ballots just as with conventional fill-in-the-oval, but a special pen makes the ink visible so that voters can note the confirmation codes if they...
Service-Oriented Architecture (SOA) has been adopted in many critical information systems in many application domains, such as health care, scientific research, e-business, and homeland security. While SOA has many advantages, such as rapid composition, deployment, and dynamic adaptation of service-based systems, many issues on security, privacy, risk, and trust in service-oriented environments need...
To protect user privacy in the search engine context, most current approaches, such as private information retrieval and privacy preserving data mining, require a server-side deployment, thus users have little control over their data and privacy. In this paper we propose a user-side solution within the context of keyword based search. We model the search privacy threat as an information inference...
Construction of learning structures for Bayesian networks is considered in this work when data is securely maintained by different parties, not willing to reveal their individual private data to each other. We propose a privacy-preserving protocol for Bayesian network from data which is homogeneously partitioned among two or more parties by using K2 algorithm, a heuristic algorithm typically used...
Constraint satisfaction has been a very successful paradigm for solving problems such as resource allocation and planning. Many of these problems pose themselves in a context involving multiple agents, and protecting privacy of information among them is often desirable. Secure multiparty computation (SMC) provides methods that in principle allow such computation without leaking any information. However,...
Social networking sites, such as MySpace, Facebook and Flickr, are gaining more and more popularity among Internet users. As users are enjoying this new style of networking, privacy concerns are also attracting increasing public attention due to reports about privacy breaches on social networking sites. We propose FaceCloak, an architecture that protects user privacy on a social networking site by...
