Feed Forward Networks in Color Extended Visual Cryptography to Generate Meaningful Shares
J. Ida Christy, V. Seenivasagam · International Journal of Security and Its Applications · 2015
Conventional visual secret sharing schemes generate noise-like random pixels on shares to hide secret images.It suffers a management problem, because of which dealers cannot visually identify each share.This problem is solved by the Extended Visual Cryptography Scheme (EVCS), which adds a meaningful cover image in each share.However, the previous approaches involving the EVCS for color images suffer from a pixel expansion problem.In this paper, we propose a general approach to solve the abovementioned problem; the approach can be used for color images in non computer-aided decryption environments.The proposed approach uses Feed Forward Network to construct the shares.The experimental results indicate that a solution to the pixel expansion problem of the EVCS is achieved.Moreover, the display quality of the recovered image is better than that obtained using other VC schemes.
