IntroductionGoogle Glass is a wearable computer, which resembles a pair of glass with a high-resolution optical head-mounted display (OHMD). As the name suggests, it was developed by Google as part of one of their research and development projects called “Project Glass” [1]. The product was designed to be an omnipresent computer that displays information, communicates over the Internet, and interacts with the user through natural language voice commands beginning with "ok glass." Google Glass runs the Android operating system and comes with 12GB of usable storage, WiFi and Bluetooth connectivity, and a 5-megapixel camera capable of shooting 720p video. The device allows users to capture images, record videos, connect to the Internet, upload images and videos, and interact with social networks and one's mobile phone [2]. The consumer version of Google Glass will be available on the retail market in early 2014. Google Glass' ability to augment reality makes it likely to become widely used and become one of the most promising "wearable computing" devices. The augmented reality of Google Glass can be used in practical scenarios such as translating and presenting text to the user in real time, or can be used as a navigation system by displaying the user's location on the map . According to Mann, inventor of EyeTap which is Similar to Glass, these devices affect both privacy and secrecy by introducing bilateral surveillance and sousveillance [3]. There have been many concerns regarding the intrusion into privacy and ethical implications of using the device in public and recording people without their permission, a possible privacy violation by Google, security breaches and others. This essay explores the privacy threats presented by Google Glass, particularly unauthorized tracking. .... middle of paper ...... “Surveillance city?
