“…The traditional VCS, which encrypts only a single image, has been extended to handle multiple secrets using two circle shares and different rotation angles [7]. Universal shares can decrypt multiple images using a unique share [8,9]. Among the various approaches, methods that employ universal shares [8,9] are most closely related to our proposed approach: our common share is a type of universal share.…”

Visual cryptography (VC) is an encryption technique for hiding a secret image in distributed and shared images (referred to as shares). VC schemes are employed to encrypt multiple images as meaningless, noisy patterns or meaningful images. However, decrypting multiple secret images using a unique share is difficult with traditional VC. We propose an approach to hide multiple images in meaningful shares. We can decrypt multiple images simultaneously using a common share, which we refer to as a magic sheet.The magic sheet decrypts multiple secret images depending on a given share. The shares are printed on transparencies, and decryption is performed by physically superimposing the transparencies. We evaluate the proposed method using binary, grayscale, and color images.

“…A well-known approach developed by Thien and Lin [9] is secret image with friendly shadows(shares), which generates a meaningful share in one step. Another method of managing shares is to design a special share, for instance, Fang [2] presented a universal share method. The special share recovers different secret images with different groups of dealers.…”

Secret image sharing is a sharing method to transmit and store images with fault tolerance property. The paper proposes a recursive method to extend conventional secret image sharing more general in application which is named multi-layer secret image sharing. It enables users more controllability to secret images than conventional secret image sharing. Moreover, a useful application is also introduced in this paper.

Recently, Fang and Lin proposed a multiple images sharing system with a universal share. This universal share can be usedfor a company's organizer to attend the recovery meeting of any shared images. Since the organizer only needs to keep the unique share, it reduces the difficulties ofthe share management ofthe organizer. However, the universal share is embedded into a secret by the least-significant-bits (LSB) substitution method before evaluating all the shares of the secret. The secret image becomes a distortion image. The original secret cannot be reconstructed without loss. In this paper, we present a distortionfree sharing schemefor the sharing ofmultiple images. Instead of using LSB to embed a universal share, all the bits ofthe secret image and the universal share are used to generate the coefficients of sharing polynomials. Moreover, this paper employs the Galois Field GF(2 8 ) instead of GF(251). Since all the information of the security image is hiding in those polynomials, the original secret can be revealed without any distortion.
