Query: Security against jamming and noise exclusion in imaging   We describe a protocol by which an imaging system could be protected against
jamming by a malevolent party. Our protocol not only allows recognition of the
jamming, but also allows for the recovery of the true image from the jammed
one. We apply the method to jamming of quantum ghost imaging, for which the
jamming detection probability is increased when the imaging light is entangled.
The method can also be used to provide image recovery in general noisy
environments.
