 The debates about privacy are almost always revolving around new technology, ranging from genetics and the extensive study of bio-markers, brain imaging, drones, wearable sensors and sensor networks, social media, smart phones, closed circuit television, to government cybersecurity programs, direct marketing, RFID tags, Big Data, head-mounted displays and search engines. There are basically two reactions to the flood of new technology and its impact on personal information and privacy: the first reaction, held by many people in IT industry and in R&amp;D, is that we have zero privacy in the digital age and that there is no way we can protect it, so we should get used to the new world and get over it (Sprenger 1999). The other reaction is that our privacy is more important than ever and that we can and we must attempt to protect it.
