—We put forward a framework to address a problem created by the rapidly spreading use of imaging devices and related to involuntarily or unintentionally photographed individuals: their pictures can accumulate additional meta information via face recognition systems and can be manually tagged via social networks and publishing platforms. With this framework(More)
2D barcodes offer many benefits compared to 1D barcodes, such as high information density and robustness. Before their introduction to the mobile phone ecosystem, they have been widely used in specific applications, such as logistics or ticketing. However, there are multiple competing standards with different benefits and drawbacks. Therefore, reader(More)
<i>IMSI Catchers</i> are used in mobile networks to identify and eavesdrop on phones. When, the number of vendors increased and prices dropped, the device became available to much larger audiences. Self-made devices based on open source software are available for about US$ 1,500. In this paper, we identify and describe multiple methods of detecting(More)
—This paper describes a prototype built as part of the Centrobot project. We present a web application intended for sharing robotics educational material. The system will allow browsing and editing a large set of projects, which we call robtivities (robotic activities). The aim of the portal is to supply information, robotivities and metadata, which can be(More)
—The history of computers is full of underestimation: 640 kilobyte, 2-digit years, and 32-bit Internet addresses. IPv6 was invented to overcome the latter as well as to revise other drawbacks and security vulnerabilities of its predecessor IPv4. Initially considered the savior in terms of security because of its mandatory IPsec support, it turned out not to(More)
—Intentionally inserted malfunctions in integrated circuits, referred to as Hardware Trojans, have become an emerging threat. Recently, the scientific community started to propose technical approaches to mitigate the threat of unspecified and potentially malicious functionality. However, these detection and prevention mechanisms are still hardly integrated(More)
