“…Note that an RSSI of -13 is actually a disconnection. Madhavapeddy and Tse performed further studies of Bluetooth propagation in our offices using a similar technique [23]. It is clear from Figure 4 that there is no deterministic relationship between distance and RSSI, but that there is a qualitative trend (larger distances are associated with more negative RSSI values).…”

Abstract. Outdoor location-based services are now prevalent due to advances in mobile technology and GPS. Indoors, however, even coarse location remains unavailable. Bluetooth has been identified as a potential location technology that mobile consumer devices already support, easing deployment and maintenance. However, Bluetooth tracking systems to date have relied on the Bluetooth inquiry mode to constantly scan for devices. This process is very slow and can be a security and privacy risk. In this paper we investigate an alternative: connection-based tracking. This permits tracking of a previously identified handset within a field of fixed base stations. Proximity is determined by creating and monitoring low-level Bluetooth connections that do not require authorisation. We investigate the properties of the low-level connections both theoretically and in practice, and show how to construct a building-wide tracking system based on this technique. We conclude that the technique is a viable alternative to inquiry-based Bluetooth tracking.

Disposable credit card numbers are a recent approach to tackling the severe problem of credit card fraud, nowadays constantly growing, especially in the context of e-commerce payments. Whenever we cannot rely on a secure communication channel between cardholder and issuer, a possibility is to generate new numbers on the basis of some common scheme, starting from a shared secret information. However, in order to make the approach meaningful from a practical point of view, the solution should guarantee backward compatibility with the current system, absence of new investments in dedicated hardware, wide-spectrum usability, and adequate security level. In this paper, we propose a solution based on the use of standard mobile phones, fully meeting the above desiderata. Importantly, our solution does not require any cryptographic support and, as a consequence, the use of PADs or smart phones, opening then its usability to a wider potential market.Key words Credit card payments -credit card fraud -disposable credit card numbers -secure payments.

“…Hightower provides an overview of the various location technologies and techniques [9]. The two basic approaches are to build the entire sensing infrastructure from the ground up (e.g., ActiveBadge [26], Cricket [20] , and Active Bat [2]) or to leverage existing infrastructure that can yield localization, either through triangulation or fingerprinting (e.g., 802.11 work such as RADAR [3] and Place Lab [12], GSM [18], and Bluetooth [14]). Applications that leverage some of these location technologies started with the original location research at Olivetti and Xerox PARC, where researchers used office tasks as motivation to create experiences such as Audio Aura, auto call forwarding, and desktop migration [16,26].…”

Abstract. Precise indoor localization is quickly becoming a reality, but application demonstrations to date have been limited to use of only a single piece of location information attached to an individual sensing device. The localized device is often held by an individual, allowing applications, often unreliably, to make high-level predictions of user intent based solely on that single piece of location information. In this paper, we demonstrate how effective integration of sensing and laser-assisted interaction results in a handheld device, the iCam, which simultaneously calculates its own location as well as the location of another object in the environment. We describe how iCam is built and demonstrate how location-aware at-a-distance interaction simplifies certain locationaware activities.
