“…Moreover, the problem of Private Proximity Testing (PPT) is a similar issue, which is only applicable in smart devices. It has attracted the attention of some researchers since 2006 [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. In PPT, the proximity of two Location Based Services (LBS) are securely examined.…”

In this paper, two protocols are presented for private intersection detection of two moving objects' trajectories. To design the first protocol, we simplify the problem of finding the intersection points to the problem of finding the common roots of the polynomials, which represent the moving objects' trajectories. Thereafter, GrÖbner Basis is used to design a novel secure protocol to find the common roots of the polynomials. Another protocol is also designed based on the distance computation of two trajectories' curves. The complexity of the GrÖbner-based protocol for finding the common roots of polynomials is numerical. Its complexity is much lower than the complexity of the garbled circuitbased protocol for Euclidean Distance Computation of l points and the complexity of the protocols for private proximity testing.

Ubiquitous computing systems are commonplace. They have opened the door to great benefits for society as a whole. However, they have to be used with care, otherwise they can cause serious risks for their users. In this chapter, we analyze the privacy risks of ubiquitous computing systems from a new individual-centred perspective based on five privacy dimensions, namely identity, location, footprint, query and intelligence. We describe each dimension and provide an introductory view of the main privacy risks of these systems. Also, we discuss some of the challenges that derive from new trends in the field.
