Privacy-Preserving Sequential Pattern Release

We investigate situations where releasing frequent sequential patterns can compromise individual’s privacy. We propose two concrete objectives for privacy protection: k-anonymity and α-dissociation. The first add...

Geometrical contributions to secret sharing theory

Finite geometry has found applications in many different fields and practical environments. We consider one such application, to the theory of secret sharing, where finite projective geometry has proved to b...

Spreads of T ₂(o), α-flocks and Ovals

We establish a representation of a spread of the generalized quadrangle T ₂(0), o an oval of PG(2, q), q even, in terms of a certain family of q ovals of PG(2, q) and investigate the properties of this representa...

Providing Anonymity in Unconditionally Secure Secret Sharing Schemes

We discuss the concept of anonymity in an unconditionally secure secret sharing scheme, proposing several types of anonymity and situations in which they might arise. We present a foundational framework and pr...

Permutations amongst the Dembowski-Ostrom Polynomials

We note that certain Dembowski-Ostrom polynomials can be obtained from the product of two linearised polynomials. We examine this subclass for permutation behaviour over finite fields. In particular, a new inf...

Characterisations of Flock Quadrangles

We characterise the Hermitian and Kantor flock generalized quadrangles of order (q ²,q), q even, (associated with the linear and Fisher–Thas–Walker flocks of a quadratic cone, and the Desarguesian and Betten–Walk...

Unitals which meet Baer subplanes in 1 moduloq points

We prove that a parabolic unitalU in a translation plane π of orderq ² with kernel containing GF(q) is a Buekenhout-Metz unital if and only if certain Baer subplanes containing the translation line of π meetU in ...
