Abstract
- A description and comparison of three visual extended cryptography algorithms is presented. Currently these methods are often used as a basis for developing more complex schemes. Results related to overlapping shades, pixel expansion, quality of images and shades, and the number of coded images are obtained. In conventional visual cryptography a secret image is encrypted into a set of images that look like random-noise and are distributed to each participant of the scheme. To obtain the secret image the images received must be super-imposed. .In the extended visual cryptography the shades are visually recognizable images. It is concluded that the three methods present particular advantages depending on the application. [ABSTRACT FROM AUTHOR]
