| 520 | 3 | |a In this paper, a visual secret sharing scheme for case (k, n) based on random noise balanced error diffusion (RNBED) is proposed. The proposed scheme satisfies (k, n) threshold, requiring no codebook design, and avoiding the pixel expansion problem. In addition, it improves existing schemes in terms of contrast and evenness, which are two important metrics for evaluating the visual quality of recovered secret. Experimental results and security analyses show the effectiveness of the proposed scheme. Comparisons with previous approaches show the advantages of the proposed scheme. | |
