Recursive Visual Secret Sharing for Biometric Authentication
Visual Secret Sharing (VSS) or Visual Cryptography is a single level encryption used to share a secret image in the form of shares among group of users and the image decryption can be done by stacking the shares without the prior knowledge of encryption and with no cryptographic computations. In the Recursive Visual secret Sharing (RVSS), the original image is encrypted into first level, second level, third level shares and so on. For n levels 2n shares are generated. In this paper, a new method of Biometric authentication using 2-outof- 2VSSwith two levels encryption is proposed, where the output of first level shares becomes the input to the second level shares generation. The security of the Biometric Image (BI) can be improved by increasing the levels of share generation (encryption) and decrypted image is obtained by stacking all level shares.
