SECURE VISUAL SECRET SHARING BASED ON DISCRETE WAVELET TRANSFORM [PDF]
ICTACT Journal on Image and Video Processing, 2015 Visual Cryptography Scheme (VCS) is an encryption method to encode secret written materials. This method converts the secret written material into an image. Then encode this secret image into n shadow images called shares.

DIGITAL COLOR IMAGE ENCRYPTION BASED ON INVERTIBLE MATRIX WITH SECRET SHARING [PDF]
ICTACT Journal on Image and Video Processing, 2013 This paper explores the new approach to implement image encryption in digital color images. The self invertible matrix created from the original image is used as keys for the RGB to YCbCr transform and the secret sharing operations.

XOR-based unexpanded meaningful visual secret sharing scheme
Int. J. Secur. Networks, 2019 Visual cryptography is a technique to conceal the secret information into n shares, distributed to n participants. When any k ≤ n, 2 ≤ k ≤ n, shares are printed on transparencies and stacked together, information about secret image can be revealed ...

Weighted visual secret sharing with multiple decryptions and lossless recovery.
Mathematical biosciences and engineering : MBE, 2019 Traditional visual secret sharing (VSS) encodes the original secret image into n shares, and each share is of equal importance. However, in some scenarios, we need to make a difference between the participants according to the levels of their importance.

Magic sheets: Visual cryptography with common shares
Computational Visual Media, 2018 Visual cryptography (VC) is an encryption technique for hiding a secret image in distributed and shared images (referred to as shares). VC schemes are employed to encrypt multiple images as meaningless, noisy patterns or meaningful images.

Secret Image Sharing using Visual Cryptography Shares with Acknowledgement
International Journal of Innovative Technology and Exploring Engineering, 2019 Visual Cryptography is an encryption technique in which the secret image is encoded and divided into n meaningless images called shares. The shares look like black and white dots embedded randomly in an image. These shares don’t reveal any information about the original image.

A New Repeating Color Watermarking Scheme Based on Human Visual Model
EURASIP Journal on Advances in Signal Processing, 2004 This paper proposes a human-visual-model-based scheme that effectively protects the intellectual copyright of digital images. In the proposed method, the theory of the visual secret sharing scheme is used to create a master watermark share and a secret ...

Meaningful And Unexpanded Shares For Visual Secret Sharing Schemes
, 2015 In today s internet world it is very essential to secretly share biometric data stored in the central database. There are so many options to secretly share biometri c data using cryptographic computation. This work reviews and applies a perfectly secure method to secretly share biometric data,for possible use in biometric authentication and protection ...
