Executive Summary

A biometric authentication system operates by acquiring raw biometric data from a subject, extracting a feature set from the data and comparing the feature set against the templates stored in a database in order to identify a person or to verify a claimed identity. The template data in the database is generated during enrolment and is often stored along with the original raw data. This paper explores the possibility of using visual cryptography without pixel expansion for imparting privacy to biometric data such as fingerprint images, iris codes, and face images.
