Smart phone surveillance is a sensitive issue, so topical and important, which is about everyday life of all of us, I am talking about the smart phones, small smart phones, these small but powerful computers that everybody use them everyday by doing more internet browsing rather than doing calls. The questions that arise about the security of smart phones are many, for example: may someone watch us? may the government hear what we saying and what messages we send? may they know our location? How much important meta-data is and to what extent it can reveal important information about the subscribers identity and how it relates to privacy and personal data. Finally, it is worth mentioning the participation of mobile phone providers in various government monitoring projects of the citizens either with targeted software which is not detectable, or with the direct access to the Servers of the providers for copying sensitive information without of course the consent of the subscribers. Such projects are the Carnivore, Prism, and other projects, and the countries involved in information exchange programs are behind lists identified as 5 Eyes, 9 Eyes, and 14 Eyes.
