Abstract
The strategy for the selection of an optimal time function for dynamic visual cryptography is presented in this paper. Evolutionary algorithms are used to obtain the symmetric piece-wise uniform density function. The fitness function of each chromosome is associated with the derivative of the standard of the time-averaged moiré image. The reconstructed near-optimal time function represents the smallest interval of amplitudes where an interpretable moiré pattern is generated in the time-averaged image. Such time functions can be effectively exploited in computational implementation of secure dynamic visual cryptography.
