Context based enforcement of authorization for privacy and security in identity management

Protecting the identity of an individual is a shared responsibility between the individual, the organizations with whom the individual will be transacting during her life time, and the state of which the individual is a legal resident. Identity theft occurs when someone uses an individual's personal information without the knowledge of the individual to commit a crime, such as fraud or theft. Of late identity theft has become one of the fastest growing crimes, not only in western countries but also in developing countries where internet dominates business, financial transactions of big organizations, and social activities of individuals. In this paper we discuss a context based enforcement of authorization to protect the privacy of individuals and secure information about them stored in large identity management systems.
