Copyright protection for progressive image transmission with qr code and secret sharing applications [PDF]

, 2018
Progressive image transmission (PIT) can be commonly encountered in the browsers due to the bandwidth consumption of different users. With the digital nature of images, they can be easily copied and spread, and hence copyright protection of progressively

Distortion free geometry based secret image sharing

, 2011
Blakley proposed a method to share a secret among a number of participants in 1979. His method uses the fact that a point (secret) in k-dimensional space is the intersection point of k hyperplanes.

Upper bound limit analysis of coral reef limestone cavern roof stability incorporating a tension‐shear failure mechanism with tensile‐strength cut‐off

Deep Underground Science and Engineering, EarlyView.
For the roof of coral reef limestone caverns, a novel tension‐shear composite failure mechanism was developed. The most critical tensile crack model was identified using a hybrid optimization algorithm, and the stability of the cavern roof was analyzed accordingly.

Secret Image Hiding and Sharing Based on the (t, n)-Threshold

, 2012
[[abstract]]This study proposes a new secret image sharing method based on the (t, n)-threshold.The sharing method is completed through three main steps: (1) quantizing the secret image, (2) generating n shadows from the quantized image, and (3) sharing ...

Weighted modulated secret image sharing method

, 2012
[[abstract]]We present a novel hybrid method that includes a modulated scheme for reducing the distortion of the reconstructed image and a two-layered structure for grouping participants with different weights in a secret image sharing problem ...

Rock mechanical properties under reconstructed deep in situ thermo–hydro–mechanical conditions: Implications for CO₂‐related injection scenarios

Deep Underground Science and Engineering, EarlyView.
The graphical abstract illustrates a reconstructed in situ thermo‐hydro‐mechanical (THM) framework in which porosity serves as the central variable linking stress, pore pressure, and temperature to evolving mechanical properties of rocks. Under burial conditions, in situ stress, pore pressure, and temperature jointly govern volumetric strain and ...

Secret Image Sharing with Reversible Steganography

, 2010
[[abstract]]The significant essential of secret image sharing approaches is that the revealed content of the secret image must be lossless. Moreover, the distorted stego images can be reverted to the original cover image.

Secret image sharing with multi-sized shadow images: Balancing concealment and communication overhead

Journal of King Saud University: Computer and Information Sciences
Secret image sharing (SIS) possesses advantageous attributes such as loss tolerance, offering a promising solution for image protection. However, the issue remains unresolved, which is the trade-off between the transmission or storage overhead of shadow ...
