Digital watermarking is the enabling technology to prove ownership on copyrighted material, detect originators of illegally made copies, monitor the usage of the copyrighted multimedia data and analyze the spread spectrum of the data over networks and servers. Embedding of unique customer identification as a watermark into data is called fingerprinting to… (More)
In P G(2, q 2), q a prime power, we study the set T of Baer subplanes that contain a fixed triangle P QR. To construct a linear rank 2–geometry over T , we determine the dihedral groups, their orders and possible extensions that are generated by the involutions of two Baer subplanes of T. If q +1 is an odd prime, the (q +1) 2 Baer subplanes through the… (More)
In the past, the computer has been used in geometry largely in order to solve particular problems of construction or non-existence.
Given a finite field F = GF (q n) of order q n it is well-known that the map f : F → F , f : x → x q is a field automorphism of F of order n, called the Frobenius automor-phism. If V is an n-dimensional vector space over the finite field GF (q), then V can be considered as the vector space of the field GF (q n) over GF (q). Therefore the Frobenius… (More)
