Voronoi-based image representation applied to binary visual cryptography

作者:

Highlights:

• Voronoi-based Visual Cryptography can drastically reduce the size of image shares.

• VVC can make VC secure with a private random generator and point-based image coding.

• Shape reconstruction properties of the Voronoi-based image representation are stated.

• VVC can support VC for low-resource technologies and for transmission reliability.

• VVC transfers powerful Voronoi properties to traditional VC schemes.
