Abstract
Recently, three visual cryptography schemes with
t
-error-correcting capability (VCSs-
t
EC) were introduced for preventing the shadows carrying additional information from being corrupted by noise interference. However, the concerns on VCS-
t
EC, such as the average amount of carrying information, decoding of information from shadows, and the demonstration way of a secret, should be considered and improved. In this article, two schemes, namely the (
k, n
) probabilistic VCS-
t
EC (PVCS-
t
EC) and the (2,
n
) deterministic VCS-
t
EC (DVCS-
t
EC), are proposed. The concept of probabilistic VCS is combined with the Bose-Chaudhuri-Hocquenghem code (BCH code) for designing the (
k, n
) PVCS-
t
EC. Furthermore, some constant-weight BCH codewords are adopted to build the (2,
n
)-DVCS-
t
EC. Comprehensive results and experiments are demonstrated to clarify the enhancement of information-carrying and decoding by the two proposed methods.
