Description
Summary:This study proposes a novel multi-image threshold sharing scheme based on Chinese remainder theorem and Lagrange interpolation. The exceptional property of the scheme is its ability to retrieve any secret image without recovering all the other images. Therefore, it works efficiently and reduces computation cost in case it needs to recover only one image from shares. In term of capacity, the scheme has no limitation on number of input secret images, output shares and the recovery threshold. Another advantage of the scheme is that it can be used for many image formats whether it is binary or grayscale or color. Moreover, the scheme can recover the secret images without any distortion. •Distortion free multi-image sharing.•No limitation on the number of input secret images, output shadows, and threshold value.•Applicable to binary, grayscale, and color images.•Has ability to retrieve any secret image without recovering all the secrets.
