Image hatching (or nonphotorealistic line-art) is a technique widely used in the printing or engraving of currency. Diverse styles of brush strokes have previously been adopted for different areas of an image to create aesthetically pleasing textures and shading. Because there is no continuous tone within these types of images, a multilevel scheme is proposed, which uses different textures based on a threshold level. These textures are then applied to the different levels and are then combined to build up the final hatched image. The proposed technique allows a secret to be hidden using Visual Cryptography (VC) within the hatched images. Visual cryptography provides a very powerful means by which one secret can be distributed into two or more pieces known as shares. When the shares are superimposed exactly together, the original secret can be recovered without computation. Also provided is a comparison between the original grayscale images and the resulting hatched images that are generated by the proposed algorithm. This reinforces that the overall quality of the hatched scheme is sufficient. The Structural SIMilarity index (SSIM) is used to perform this comparison.

Image hatching (or non-photorealistic line-art) is a technique widely applied in the printing or engraving of currency. Diverse styles of brush strokes have previously been adopted for different areas of an image to create textures and shading. Because there is no continuous tone within these types of images, we propose a multi-level scheme, which uses different textures based on a threshold level. These textures are then applied to the different levels and are then combined to build up the final image. We propose a technique by which one can hide a secret using visual cryptography (VC) within the hatched images. Visual cryptography provides a very powerful means by which one secret can be distributed into two or more pieces known as shares. When the shares are superimposed exactly together, the original secret can be discovered without computer participation.

“…The OpenID Connect protocol can effectively solve the problem that the authentication is incomplete and the password security is not strong enough so that you can also achieve control authority. Visual cryptography can hide multiple secret information in a small amount of memory [7], with the advantages of simple technology implementation and low computational complexity.…”

OIDC protocol is one of the latest applications in the WoT application layer of a single sign-on protocol. In order to solve WoT application layer authentication and authorization issues, this paper presents a multi-secret visual cryptography scheme, combined with OIDC protocol, to achieve WoT application layer authentication and authorization functions. Multi-secret visual cryptography technology can hide a lot of secret information in a small amount of memory, while it can make up for OIDC defects. This solution can improve the security of WoT application layer under the premise of reducing the security.
