Visual cryptography research papers

In way that encrypted image can be decrypted by the human vision if the correct image key is used. by this cryptographic technique we can encrypt visual information ( pictures text etc. ) in a way that human visual system can perform decryption of. call for papers - international journal of science research ( ijsr) visual cryptography research papers is a peer reviewed, monthly open access international journal. a review of image steganographic technique based on extended visual cryptography scheme. two novel visual cryptography ( vc) schemes are proposed by combining vc with single- pixel imaging ( spi) for the first time. it is pointed out that the overlapping of visual key images in vc is similar to the superposition of pixel intensities by a single- pixel detector in spi. in the first scheme, qr- code vc is designed by using opaque sheets instead of transparent sheets.

visual cryptography is introduced by first in 1994 by noar and shamir [ 1]. visual cryptography is a cryptographic technique which allows visual information ( e. printed text hand written notes pictures) to be encrypted in such a way that the decryption can be performed by the human visual. presented joint visual cryptography and watermarking ( jvw) algorithm. in this researcher paper they work on both watermarking and visual cryptography involve a hidden secret image. for visual cryptography secret image encoded into shares, more shares are required to decode the secret image. this unique book describes the fundamental concepts theories practice of visual cryptography. the design analysis, construction, application of visual cryptography schemes ( vcss) are discussed in detail. original size invariant, cutting- edge research is presented on probabilistic . the obtained visual quality is much better than all previous visual cryptography techniques.
