Keystroke dynamics analysis has been applied successfully to password or fixed short texts verification as a means to reduce their inherent security limitations, because their length and the fact of being typed often makes their characteristic timings fairly stable. On the other hand, free text analysis has been neglected until recent years due to the(More)
Replication of experiments lies at the very core of the scientific process. In spite of this, the relevance and relative count of replication studies has fallen sharply in the recent past in several disciplines and a similar trend is apparent in computing science and software engineering. Keystroke dynamics studies have not been exempted from this rule,(More)
In this paper, chromatic fiber-dispersion effects are studied in a radio-over-fiber (RoF) system with optical phase modulation and coherent detection at 60, 75 and 100 GHz using binary and quaternary phase-shift-keying (PSK) modulation over 40 and 80 km of single-mode-fiber. Electrical spectrum at the receiver and constellation diagrams are analyzed, and(More)
