We describe a technique for image verification by use of real-time joint transform correlation with scanning technique. The described method is independent of a spatial light modulator (SLM) in the Fourier plane which has limitations for applying to robust systems. The system is a hybrid processing combined of optical and electronic methods. The system also can perform real-time correlation without SLM at Fourier plane. We develop the theory of the technique and evaluate a performance of the method by estimating the correlation between an authentic fingerprint image and the distorted fingerprints image. Also, we present computer simulation result to demonstrate the validity of the idea.
