Visual Cryptography
A Rust implementation of visual cryptography algorithms supporting multiple schemes and configurable block sizes.
Overview
Visual cryptography is a cryptographic technique that allows visual information (images) to be encrypted in such a way that the decryption can be performed by the human visual system without any complex cryptographic computations. The basic principle involves splitting a secret image into multiple shares that appear as random noise, but when overlaid, reveal the original secret.
Implemented schemes
-
Naor & Shamir (1994)
-
XOR-based scheme for better contrast without pixel expansion (Naor & Shamir uses AND operation and 2x2 pixel expansion)
-
Nakajima & Yamaguchi (2002)
-
Taghaddos & Latif (2014)
-
Dhiman & Kasana (2018)
Schemes to be implemented
-
Visual cryptography for color images by Young–Chang Hou (2003) (didn't manage to find a free paper)
-
A QR code-based user-friendly visual cryptography scheme (QEVCS) by Lijing Ren & Denghui Zhang (2022)
Schemes to be evaluated
- Extended Visual Cryptography for Natural Images (Nakajima & Yamaguchi, 2002) (don't like the current output, need thorough testing, smth is definitely wrong)
