Advanced Robust Data Hiding Using Visual Cryptography
Leelavathi Rudraksha, M. N. Giri Prasad · 2019
Visual cryptography is an algorithm used for encrypting digital media like images, text etc in which the decryption can be performed by visual mechanical operations rather than using a computer. In this paper, a novel visual cryptography scheme with k-n secret sharing is proposed which are then hidden in envelope cover mages using LSB technique for secure data transmission. As the creation of n shares uses random data input, a random number generator algorithm is used for obtain inputs for share generation. This technique needs very less mathematical calculation compare with other existing techniques of visual cryptography on color images.
