Sheltered iris attestation by means of Visual Cryptography (SIA-VC)

Biometric techniques consists of uniquely identifying a person based on their physical characteristic or behavioral characteristic. It is mainly used for authentication purpose. Iris is one of the most powerful technique among all biometrics because of its uniqueness and stability. For authentication, the feature template in the database and the user template should be the same. Storing the template in the database securely is troublesome, because it can be compromised. In order to overcome this issue, in this paper a new method for securely storing the template in the database is proposed. This method uses Visual Cryptography (VC) concept and will generate shares, that shares will be stored in the database. The proposed Visual Cryptography fashion will generate meaningful shares which overcomes the problem in existing methods. Thus this new operandi will provide a great means of security and an extravagance layer for endorsement.
