Visual cryptography schemes (VCSs) are the methods to provide data security in network systems by generating random and non meaningful shares of a original image under consideration. There occurs a problem of transmission loss and also the possibility of the intruder attack when the shares are passed within the same network. Previous research have focused on hiding the shares in halftone images but the possible risks they lead to are pixel expansion problems and degradation in the quality of the resultant images. Hence a binocular VCS (BVCS) and an encryption algorithm are proposed to hide the shared pixels in the single image random dot stereogram’s (SIRDSs) along with the different modes of transmission for the generated possible shares. Since the SIRDSs have the same 2D appearance as the conventional shares of a VCS, this paper tries to use SIRDSs as cover images of the shares of VCSs to reduce the transmission risk of the shares. The encryption algorithm used may modify the random dots in SIRDS’s to equalize the quality of the resultant image. This process is done using the construction rule of BVCS. Altering the dots may also have a impact on the pixel quality and hence an optimization model based on the quality requirement is used. Finally the shares are passed to the recipients over varied networks
