Download or read book Cellular Convergence and the Death of Privacy written by Professor Stephen B. Wicker and published by Oxford University Press. This book was released on 2013-08-21 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cellular technology has always been a surveillance technology, but "cellular convergence" - the growing trend for all forms of communication to consolidate onto the cellular handset - has dramatically increased the impact of that surveillance. In Cellular Convergence and the Death of Privacy, Stephen Wicker explores this unprecedented threat to privacy from three distinct but overlapping perspectives: the technical, the legal, and the social. Professor Wicker first describes cellular technology and cellular surveillance using language accessible to non-specialists. He then examines current legislation and Supreme Court jurisprudence that form the framework for discussions about rights in the context of cellular surveillance. Lastly, he addresses the social impact of surveillance on individual users. The story he tells is one of a technology that is changing the face of politics and economics, but in ways that remain highly uncertain.

If you're itching to cut the copper cord with your costly, traditional phone service, you need Talk is Cheap, the new, easy-to-understand guide to understanding and using Voice over Internet Protocol (VoIP) and other Internet telephone options.Technologies such as VoIP are gaining a great deal of attention these days as more people switch from standard telephone service to phone service via the Internet. But while the cost savings are outstanding, there are some issues with Internet telephony that you should know about. Are the connections reliable? Is the quality comparable? Will it include 911 services?James Gaskin's Talk is Cheap addresses these issues and many more by explaining how to make the switch and what the tradeoffs will be if you opt for Internet telephony over traditional phone services.Talk is Cheap focuses on the increasingly popular services from Vonage, which uses VoIP, and Skype--a free service that operates as a peer-to-peer (P2P) network with the ability to turn any PC, Mac, or Pocket PC into a telephone.
