Weighted Threshold Secret Image Sharing [PDF]
, 2009 Given a secret image I, a threshold r, and a set of n ( ≥ r) participants P = {1, 2, ... , n} with a set of weights W = {w 1, w 2, ... , w n } where w i is the weight (which indicates the degree/rank of importance) of participant i and we assume that w 1 ≤ w 2 ≤ ... w n . The idea of weighted threshold secret image sharing encodes I into n shadows S 1,

New Design for Friendly Visual Secret Sharing
, 2014 NSC101-2221-E-032-047Different from conventional cryptography, visual cryptography is an image cryptographic technique proposed by Naor and Shamir. It encodes a secret image into n pieces of noise-like shares.

A verifiable essential secret image sharing scheme based on HLRs (VESIS‐(t, s, k, n))
CAAI Transactions on Intelligence TechnologyIn traditional secret image sharing schemes, a secret image is shared among shareholders who have the same position. But if the shareholders have two different positions, essential and non‐essential, it is necessary to use essential secret image sharing ...

A Secret Image Restoring Scheme Using Threshold Pairs of Unordered Image Shares
IEEE Access, 2019 Secret image sharing has been widely used in numerous areas such as remote sensing and information security. The goal is to share and recover one or more images using several image shares. However, most schemes only consider ordered shares.

Analysis of Secret Image Sharing using Shared Image
International Journal of Computer Applications, 2014 secret image sharing scheme with steganography lacks to provide the authentication, quality of stego-image and more cheating done by the dishonest participants. So, a secret image sharing using shared image technique is proposed to prevent the participants from the subsidiary stipulation of a false stego-image (an image containing the hidden secret ...

Deep Underground Science and Engineering, EarlyView.Cement infill shares compressive and shear stresses during loading, while interfacial friction hinders crack propagation and reduces stress concentration, improving the rock's load‐bearing capacity. Failure modes vary with crack inclination. Unfilled specimens show four modes.

Deep Underground Science and Engineering, EarlyView.The evolution of the temperature field and frozen wall under different fracture conditions was examined by an artificial ground freezing‐based thermal‐hydraulic coupled model. It was observed that fracture inclination affects the interaction extent of freezing pipes and fracture, while phase transition extent is the dominant factor for heat transfer in
