Authentication capability and stego image distortion" issues of secret sharing schemes are addressed and improved by the proposed scheme in this paper. Reduced fake stego block authentication probability and improved stego image Peak Signal to Noise Ratio (PSNR) are achieved by encoding both the share and authentication bits by XOR. Employing only eight bit for both share and authentication reduces the probability of authenticating a fake stego block to 1/256 with 44 dB average PSNR stego images. Experimental results indicate improvements compared to similar studies reported in the literature.
