Plane Transform Visual Cryptography

摘要

Plane transformation visual cryptography takes a unique approach to some of the current shortcomings of current visual cryptography techniques. Typically, the direction and placement of the encrypted shares is critical when attempting to recover the secret. Many schemes are highly dependant on this stacking order. Within this paper, the scheme presented illustrates a technique whereby this restriction is loosened such that the number of acceptable alignment points is increased by performing a simple plane transform on one of the shares. This results in the same secret being recovered when the shares correctly aligned. The technique has also been extended to encompass multiple secrets, each of which can be recovered depending on the type of transformation performed on the shares.
