A secret image sharing scheme for light images
In this study, a new (r, n)-threshold secret image sharing scheme with low information overhead for images is provided, which has a low distortion rate, and is more applicable for light images. A secret image is encoded into n noise-like shadow images to satisfy the condition that any r of the n shares can be used to reveal the secret image, and no information on the secret can be revealed from...
متن کاملA Meaningful Scheme for Sharing Secret Images Using Mosaic Images
Secret image sharing (SIS) technique protects an image by sharing it among many users. Most existing SIS schemes produce meaningless shadow images, which tends to cause attackers’ suspicion. In this paper, a meaningful secret image sharing scheme is proposed that, for the first time, uses mosaic images as the shadow images. The secret image is divided into several parts, and each part is transf...
متن کاملNonlinear Secret Image Sharing Scheme
Over the past decade, most of secret image sharing schemes have been proposed by using Shamir's technique. It is based on a linear combination polynomial arithmetic. Although Shamir's technique based secret image sharing schemes are efficient and scalable for various environments, there exists a security threat such as Tompa-Woll attack. Renvall and Ding proposed a new secret sharing technique ...
متن کاملVisual Secret Sharing Scheme using Grayscale Images
Pixel expansion and the quality of the reconstructed secret image has been a major issue of visual secret sharing (VSS) schemes. A number of probabilistic VSS schemes with minimum pixel expansion have been proposed for black and white (binary) secret images. This paper presents a probabilistic (2, 3)-VSS scheme for gray scale images. Its pixel expansion is larger in size but the quality of the ...
متن کاملA {k, n}-Secret Sharing Scheme for Color Images
This paper introduces a new {k, n}-secret sharing scheme for color images. The proposed method encrypts the color image into n color shares. The secret information is recovered only if the k (or more) allowed shares are available for decryption. The proposed method utilizes the conventional {k, n}-secret sharing strategy by operating at the bit-levels of the decomposed color image. Modifying th...
