(n, n+1) Visual Secret Sharing Scheme Based on Local Binary Pattern Operator

Abstract

A novel (n,n+1) Visual Secret Sharing (VSS) Scheme based on Local Binary Pattern (LBP) operators was presented in this paper. The proposed schemes without adopting Boolean operations make full use of the local contrast features of LBP operators to conceal secret image data into different image shares, which can then be used to recover the secret easily and exactly through the computation of LBP operators. Compared with state-of-the-art algorithms, experiments show that our proposed schemes demonstrate good randomness in shares and exact determination in reconstruction process without much computational cost.
