Steganography of SPA is one of the important research subjects in the field of information security. And HSBH is an effective image hiding algorithm. It proves that SPA can detect HSBH algorithm in theory and experiment. This method not only can detect the existence of messages embedded by sequential or random replacement, but also can estimate the hiding capability. Experimental results show that the correct rate of detection is above 95% when the embedding rate p>3%.
