Weak coherent source (WCS) and spontaneous parametric down converted heralded single photon pairs have found applications in quantum key distribution (QKD) and quantum imaging (QI) experiments. Decoy state methods have also been used to enhance the security for QKD and QI. We study quantum secured imaging with the decoy state heralded single photon source (HSPS). The HSPSs superior performance in low photon number regimes makes it an ideal candidate for integrating quantum key distribution protocols to reduce measurement uncertainty and ensure secure QI. Furthermore, our results also infer the influence of the decoy state WCS, due to its higher operating speed than decoy state HSPS, would be effective in conditions that allow higher mean photon numbers for quantum secured imaging.
