| الوصف: | Progressive Visual Secret Sharing (PVSS) is a Visual Secret Sharing scheme which shares a secret image among multiple users and during the decryption this secret image can be reconstructed in a progressive manner. Recently, PVSS has been extended for priority users by giving different importance to different shares. Thus, the higher priority user holding higher importance shares obtains better visual quality compared to the lower priority users. However, existing priority based visual secret sharing suffers from the problem of inconsistent contrast and degraded visual quality. Hence, this paper uses two different approaches namely Codebook approach and Random grid approach to construct (k, n) Priority based Progressive Visual Secret Sharing (PPVSS) without pixel expansion to provide consistent contrast and better visual quality of reconstructed image. Experimental results show the effectiveness of proposed scheme compared to the existing scheme. |
