  In this paper, we propose a novel quantum-secured single-pixel imaging method
that utilizes non-classical correlations of a photon pair. Our method can
detect any attempts to deceive it by exploiting a non-classical correlation of
photon pairs while rejecting strong chaotic light illumination through photon
heralding. A security analysis based on polarization-correlation has been
conducted, demonstrating that our method has improved security compared to
existing quantum-secured imaging. More specifically, a partial deceiving
attack, which sends a mixture of a true and a false signal, can be detected
with our proposed analysis, while currently employed methods cannot. We also
provide proof-of-principle demonstrations of our method and trustworthy images
reconstructed using our security analysis. Our method can be developed using
matured techniques used in quantum secure communication, thus offering a
promising direction for practical applications in secure imaging.
