Contribution

It proposes a novel, simple approach for color visual cryptography assuming binary data, filling a gap in practical encryption methods for color images.

Findings

Enables full restoration of encrypted color images.

Provides a simple implementation framework.

Ensures security within the binary data assumption.

Abstract

While strictly black and white images have been the basis for visual cryptography, there has been a lack of an easily implemented format for colour images. This paper establishes a simple, yet secure way of implementing visual cryptography with colour, assuming a binary data representation.
