Amended Biometric Authentication using Secret Sharing
Janhavi Sirdeshpande, Sonali Chandrashekhar Patil · International Journal of Computer Applications · 2014
Visual cryptography is a secret sharing scheme where a secret image gets divided into number of pieces called shares and not a single share disclose any information about secret image.There are some automated methods to identify and verify the user based on the physiological characteristics.To deal with such methods, there is a technology called biometrics which measures and statistically analyze the biological data.The biometric samples which are stored in the database as a secret are unique for each user so that no one can predict those samples.The addition in number of users increases the size of the database which affects space and time complexity.The intent of this paper is to overcome these issues by applying (2, 2) visual cryptography for amend biometric authentication.The experimental results show great reduction in space and time complexity.
