Recursive Visual Secret Sharing Scheme using Fingerprint Authentication

Recursive Visual Secret Sharing scheme takes the idea from the basic scheme of Visual cryptography to stack two transparent shares to obtain the original image. The paper proposes a scheme of recursive creation of shares using the basic scheme and embedding secrets into the shares. This results levels of share creation i.e. n- secrets equals n/2 levels. The Recursive visual cryptography produces shares from level n-1 when encrypted. For the purpose of user identification Biometric fingerprint authentication using minutiae extraction is provided with pixel pattern match and RGBA intensity match.  Thus the proposed scheme would make efficient utilization of data.
