Abstract: Multi-image secret sharing (MSS) scheme for two decoding options by employing universal share is discussed in this manuscript. One decoding option is piling of shares to get a secret image preview and the other option needs computation of shares to get a finer view of the secret image. In the past, universal share-based MSS schemes were presented using the common share. This paper presents a universal share-based MSS scheme which also offers two-in-one decoding. Boolean-based light-weight computation is utilized for lossless recovery of secret images. The proposed scheme encodes n secret images into a pie-shaped universal share and n noisy shares. Universal share is a common share for all n secrets; hence, it offers an efficient utilization of the available network bandwidth. Experimental results illustrate the effectiveness of the proposed scheme.
