Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a technique reducing two dispersion values of a degradation level of stego images and a embedding rate in BPCS steganography technique. Threshold levels for judging complexity boundary are reevaluated by distributions of complexity which consist of complexity gained by judgment of complexity and a number of macro-blocks having its complexity. Secret information is reconstructed by the exclusive OR calculation with pseudo-random number bit by bit to avoid line noise in stego images, and then these reconstructed information is embedded into a dummy image. Experimental results about two dispersion values of a degradation level of stego images and a embedding rate have shown the validity of proposed technique.
