Construction of (4,8)-schemes of visual cryptography on the base of a class of linear hash functions
In the work, with the use of visual cryptography, a (4, 8)-scheme is constructed for sharing secret, which is a black and white image. To construct the (4,8)-scheme, the (4, 4)-scheme of visual cryptography and a class of linear hash functions are used. It is shown that using this class makes it possible to build a secure scheme with an acceptable relative contrast of the recovered secret black and white image.
