“…(k, n)-threshold ISS has a loss-tolerant property, i.e., the dealer can reconstruct the secret with at most n − k shares lost. Hence, ISS is applied to several applications, such as key management [1], digital watermarking [2], [3], identity authentication [4], [5], blockchain [6], access control [7], password transmission [8] and distributive storage for the cloud [9]- [11]. A digital image is a specific form of data, where each grayscale (binary) pixel is represented by 8 bits (1 bit); hence, ISS easily generates shares for secret sharing.…”

In reversible image secret sharing (RISS), the cover image can be recovered to some degree, and a share can be comprehensible rather than noise-like. Reversible cover images play an important role in law enforcement and medical diagnosis. The comprehensible share can not only reduce the suspicion of attackers but also improve the management efficiency of shares. In this paper, we first provide a formal definition of RISS. Then, we propose an RISS algorithm for a (k, n)-threshold based on the principle of the Chinese remainder theorem-based ISS (CRTISS). In the proposed RISS, the secret image is losslessly decoded by a modular operation, and the original cover image is recovered by a binarization operation, both of which are just simple operations. Theoretical analyses and experiments are provided to validate the proposed definition and algorithm.

The growth in the usage of internet has increased the demand for fast and accurate user identification and authentication. New threats, risks and vulnerabilities emphasize the need of a strong authentication system. Automated methods based on physiological characteristics of user are widely used to identify and verify the user. Biometric is the technology to deal with such methods which measures and statistically analyze the biological data. A biometric authentication system provides automatic authentication of an individual on the basis of unique features or characteristics possessed by an individual.The authentication system can be stronger using multiple factors for authentication process. The application like Aadhar Card uses multiple factors for authentication. There are some difficulties with multi-factor authentication system such as user privacy considerations, huge size databases and centralized database which may create security threats.To address such tribulations, the biometric authentication using secret sharing is proposed. Secret sharing will split the centralized database across the different locations. This will help in reducing the database size and removal of threats in centralized database. Also user privacy will be maintained due to decentralization of database.

“…Furthermore, regardless of how computationally powerful the device an attacker has, he cannot obtain any information about the multimedia data. As a result, secret sharing can potentially be applied to some scenarios [4], such as block chain [5], key management [6], digital watermarking [7], [8], identity authentication [9], [10], and distributive storage [11], [12].…”

Because of the importance of digital images and their extensive application to digital watermarking, block chain, access control, identity authentication, distributive storage in the cloud and so on, image secret sharing (ISS) is attracting ever-increasing attention. Share authentication is an important issue in its practical application. However, most ISS schemes with share authentication ability require a dealer to participate in the authentication (namely, dealer participatory authentication). In this paper, we design an ISS for a (k, n)-threshold with separate share authentication abilities of both dealer participatory authentication and dealer nonparticipatory authentication. The advantages of polynomial-based ISS and visual secret sharing (VSS) are skillfully fused to achieve these two authentication abilities without sending a share by using a screening operation. In addition, the designed scheme has the characteristics of low decryption (authentication) complexity, lossless decryption and no pixel expansion. Experiments and theoretical analyses are performed to show the effectiveness of the designed scheme.
