Popis:	In this paper we present a novel switching function for multiplicative watermarking systems. The switching function is based on the algebraic structure of elliptic curves over finite fields. The resulting function allows for both watermarking generator and remover to define appropriate system parameters, sharing only limited information, namely a private key. Given the definition of the switching function, we prove that the resulting watermarking parameters lead to a stable watermarking scheme. Comment: 8 pages, 3 figures, to be presented at: 11th IFAC Symposium on Fault Detection, Supervision and Safety for Technical Processes - SAFEPROCESS
