A U.S. passport not only allows an individual to travel freely in and out of the United States, but also can be used to obtain further identification documents, prove U.S. citizenship, and set up bank accounts, among other things. Because passports issued under a false identity help enable individuals to conceal their movements and activities, there is great concern that passport fraud could facilitate acts of terrorism. This book explores passport regulation and security issues, takes a look at electronic passport security features and the vulnerabilities in the current passport issuance process.
