We apply the generalized Veneziano model ($B_5$ model) in the double-Regge exchange limit to the $\gamma p\to K^{+}{K}^{-}p$ reaction. Four different cases defined by the possible combinations of the signature factors of leading Regge exchanges [$(K^{*},a_2/f_2)$, $(K^{*},\rho /\omega )$, $(K_2^{*},a_2/f_2)$, and $(K_2^{*},\rho /\omega )$] have been simulated through the Monte Carlo method. Suitable event candidates for the double-Regge exchange high-energy limit were selected employing Van Hove plots as a better alternative to kinematical cuts in the $K^{+}{K}^{-}p$ Dalitz plot. In this way we predict and analyze the double-Regge contribution to the $K^{+}{K}^{-}p$ Dalitz plot, which constitutes one of the major backgrounds in the search for strangeonia, hybrids and exotics using $\gamma p\to K^{+}{K}^{-}p$ reaction. We expect that data currently under analysis, and those to come in the future, will allow verification of the double-Regge behavior and a better assessment of this component of the amplitude.
