Ghost imaging has attracted much attention, in which the object can be reconstructed by using the correlation of intensity fluctuations. It is well known that a large number of realizations (such as 5000 or even 20,000) are usually required for object reconstructions in ghost imaging. In this Letter, we demonstrate, for the first time to our knowledge, how the reconstructed object can be authenticated using the significantly small number of realizations (i.e., less than 5% of Nyquist limit) in computational ghost imaging. The main objective for our study is to authenticate the object reconstructed by using the small number of realizations rather than to directly extract the high-fidelity object.
